Egg and Soda Science Fair Experiment: Tooth Decay Project

Krystal DeVille

July 10, 2022

Healthy teeth are essential for your overall health!

They make it a breeze for our mouths to form words and flash million-dollar smiles. This importance in our lives is why we must pay attention to a potentially adverse problem: tooth decay .

Are you having a hard time getting your child to brush their teeth? If so, it might be time to bring out the big guns by introducing the egg and soda science fair experiment to explore the concept of dental health.

Theoretically, a hard-boiled eggshell works similarly to the enamel on your child’s tooth. It protects the dentin (the soft inside of a tooth) from damage.

Unfortunately, some of our dietary habits make it difficult for the enamel to protect our teeth from damage. This science experiment will demonstrate the repercussions of our choices on our bodies, and why tooth health matters. Read on!

Egg and Soda Science Fair Experiment

What You Need

The good news is that the egg and soda science fair experiment doesn’t require a myriad of pricey supplies. They’re wallet-friendly and there’s the likelihood that you have most of them in your home. If not, they’re readily available online and can be delivered to your doorstep.

• Three clear plastic cups
• Toothpaste and a toothbrush
• Three white-shelled hard-boiled eggs

Before the Egg and Soda Science Fair Experiment

Start by talking to your child about the importance of dental hygiene practices that include brushing their teeth twice a day.

Ensure you explain how certain activities, drinks, and food, can damage and stain teeth. You’ll also want to delve into how the consumption of acidic drinks can erode tooth enamel .

Ask your child to name a few types of drinks that are detrimental to their teeth. They may list juice, soda, or coffee because of the acid and sugar.

Furthermore, you can ask your child to think of drinks that can boost the health of their teeth. They might answer water and milk.

You can also find out if they believe brushing after the consumption of some of the harmful drinks can lower the risk of damage to their teeth.

Explain the Egg and Soda Science Fair Experiment

To spark their curiosity and pique their interest, inform your child that you have a way of discovering the repercussions of leaving those harmful drinks on their teeth overnight.

With a boiled egg in hand, demonstrate how it resembles their teeth (a thin and sturdy outer shell and a soft inside). Take the time to explain the consequences of leaving the egg soaked in soda overnight, compared to water.

Additionally, consider various types of soda such as colas that have varying effects compared to their clear lemon-lime counterparts.

Another fun experiment I did with my son was the Cloud in a Bottle project. You’ll make clouds inside your house in a few different ways.

Perform the Egg and Soda Science Fair Experiment

It’s a straightforward experiment that can be performed by following the steps below.

• Boil the eggs, ensuring you have a few extra ones if some of them crack during boiling. A cracked shell on your hard-boiled egg will alter the outcome of the experiment.
• Help your child fill each of the plastic cups whereby one has water, another has diet soda, and the third contains regular soda.
• Once the eggs have boiled have your child put one in each plastic cup then leave them overnight.
• Check on the eggs the following day. You may need to pour out the liquid from each cup to examine how each egg has been affected. You’ll notice the egg in the cola has been stained.
• Discuss the changes you notice in each egg. Ask your child what they believe occurred and the solution to get the eggs back to their original state.
• Give your child some toothpaste and a toothbrush and have them attempt to brush the stains off the eggshell.

As a variation, you can boil a few additional eggs and add cups with coffee, clear soda, vinegar, and orange juice for comparison.

Understanding the Results of the Egg and Soda Science Fair Experiment

Each liquid provides essential information on how certain liquids negatively impact our teeth. The egg in water will have no changes because the acidity (pH) of water is close to your body’s resting PH. Water won’t break down your teeth, making it one of the healthiest liquids to consume.

Although the soda pop will result in softening of the outer shell of the egg, certainly not as much as vinegar. Most importantly, the soda pop will result in a discoloration of the white egg, particularly if the soda is dark. Its acid levels can result in the weakening or demineralization of the tooth enamel.

Lastly, the acidic level of vinegar is detrimental to your teeth during an acid attack. Every time you consume starch or sugar, the bacteria in your mouth utilize it to form the acid that is represented in a tooth decay experiment with vinegar.

The acidic vinegar breaks down the minerals in the eggshell just like acid does to the outer shell of your tooth. After a few days, there’s barely any shell left.

Preventing Tooth Decay

Aside from brushing your teeth every day, are there other ways to curb tooth decay? Although dentists recommend fluoride, how effective is it? You can find out by filling two clear jars with vinegar.

Then, coat one eggshell layer one eggshell entirely with gel fluoride toothpaste and put it in one jar, and put an uncoated eggshell in the second jar.

Keep an eye out for signs of decay on the uncoated eggshell as you note the condition of the coated eggshell. You shouldn’t notice decay on the coated eggshell.

The Takeaway

You and your child can learn two main things from this experiment. Firstly, the acid contained in soda and vinegar has the potential to severely erode tooth enamel.

Secondly, it takes more than just a few quick swipes with a toothbrush to get teeth spick-and-span. Therefore, incorporating healthy food choices in addition to brushing teeth every day with fluoride toothpaste is the key to preventing teeth erosion and decay.

Tooth Decay: An ‘Eggciting’ Science Experiment for Kids

• March 20, 2018
• Patient Education

Tooth Egg Experiment

If you’re looking for a fun way to teach your children about tooth decay and proper oral health, it’s time to do the Tooth Egg Experiment.  The classic experiment is one that many of us can remember doing in our youth.  It shows how an acid attack can destroy the enamel, or the outer surface of our teeth.  The materials required are commonly found in most households; so most parents won’t have to sweat a trip to the store.

Ready for a Dental Checkup With a Pediatric Dentist? Call Our Muscatine Office (563) 607-5979

Materials for the Tooth Egg Experiment

• White Eggs (one for each liquid tested, we recommend at least three)
• Diet Soda Pop

• Make hard boil eggs.  Place the eggs in a pot of water and ensure there is enough water to cover the eggs as the water boils off.  Bring the water to boil over high heat, once boiling cover the eggs, and remove them for heat and let them sit for eight to ten minutes.  Drain the water, and allow the eggs to cool.
• Place each egg in a clear cup.
• Add each selected liquid to the cups individually and ensure the liquid covers the eggs
• Let the eggs sit for 2-3 days
• Remove the eggs and inspect them for changes!  Your kids will be amazed.

Discuss The Results

Understanding the results of the Tooth Egg Experiment is important.  Each liquid can provide important information on how certain liquids affect our teeth.  The egg in water will have no changes, this is because the acidity (pH) of water is very close to the resting pH of our body.  Water will not breakdown our teeth, and is one of the healthiest liquids we can drink.

The soda pop will cause some softening of the outer shell of the egg, but not as much as the vinegar.  Most notably the soda pop will cause a discoloration of the white egg; especially if the soda pop is dark.  The acid content of soda pop can lead to the demineralization, or weakening, of our tooth enamel.

Lastly, the acidic content of vinegar shows the damage that is done to our teeth during an acid attack. Each time we consume a sugar or starch, bacteria in our mouth will utilize it to create acid.  This acid is represented in the Tooth Egg Experiment by vinegar.  The acidic vinegar breaks down the minerals in the egg’s shell just as the acid does to the outer shell of our tooth.  After a few days there is almost no shell remaining.

As each of these experiment variations showcases the potential for tooth decay, discuss the results with your children and talk about healthy food choices and the importance of a balanced diet.

Tooth Decay Experiment: Teach Kids the Importance of Brushing their Teeth

I love doing science experiments with my son. One reason is that they help children become better readers. Also, they provide learning that is hands-on and uses the three senses of sight, hearing, and touch (sometimes smelling and tasting as well). They are the best way children can apply what they are learning.

In the past, I have used science experiments to teach my son lessons in hygiene such as the importance of washing his hands . The activity I will show you today is a great complement to that experiment. It is called the Tooth Decay Experiment. This could be your child’s next science fair project (for older kids).

The Tooth Decay Experiment will show your children the importance of brushing their teeth twice a day. Furthermore, it demonstrates what happens to your teeth when you drink certain beverages such as orange juice, tea, and water.

We have fun with all our experiments; even those that don’t work. It gives us opportunities to investigate and solve problems. I tell my son this is what scientist do!

The Tooth Decay Experiment has made my son a “Flossing and Teeth Brushing Advocate!” After you do this activity, it will probably have the same impact on your child. I will show you how to do it.

Let’s Get Started!

Warning: This post contains a lot of pictures .

• 5 cups (we used paper cups)
• 5 individual labels that read: Orange Juice, Soda, Water, Tea, and Vinegar
• 1 cup of orange juice (enough to submerge an egg)
• 1 cup of dark soda (enough to submerge an egg)
• 1 cup of water (enough to submerge an egg)
• 1 cup of tea (enough to submerge an egg)
• 1 cup of vinegar (enough to submerge an egg)
• Plastic Gloves to protect hands
• Goggles to protect hands

Here is a video of my son doing the Tooth Decay Experiment. This video comes from my son’s YouTube Channel, Corban’s Fun Learning Adventures. Please like and subscribe for fun activities.

Directions:

• Make 5 individual labels that read: Orange Juice, Soda, Water, Tea, and Vinegar

If you want to know how my son learned to write the alphabet and numbers as a 2-year-old through PLAY, click this link.

• Cut the labels out and put them on the cups.

• Put the eggs in each cup.

• Pour the liquids in each labeled cup.

• Let the eggs sit in the cups for 24 hours.

• The next day take the eggs out of the cups and see what happened.

This experiment had a big impact on my son. He knows that brushing his teeth is important. After doing this activity, he said he wanted brush his teeth everyday.

Such a great experiment, it is so important to teach kids to brush their teeth.

Yes this is true! I wish I would have done this experiment as a child.

I love the hands-on experiments you provide, and this tooth decay activity is no exception! Thanks for sharing!

No problem!! Thank you for your comment!

Great idea! What a fun experiment for kids that really teaches something important!

Thank you! This is one of my favorite experiments.

What a cool experiment. I love how this teaches them to brush their teeth.

Thank you! This is one of his favorite experiments.

I absolutely love this experiment so much! My kids go to an in home school where she makes everyone brush their teeth before starting school for the day. They do it with no questions asked for her but aren’t as good to brush their teeth at home. I think they will love this!

OH good! I hope they have fun with this experiment. Thank you for your comment.

This is so informative.

Thank you! I’m glad you found it helpful.

How Liquids Affect Your Teeth : Egg Shells in Acid

This is a classic investigation into the effect of different liquids on your teeth. If you can’t get easy to access to some teeth (ask your local tooth-fairy) – then an eggshell can provide a simple stand-in. Clean (cooked & boiled) chicken bones can also work well.

You will need

• Egg shells (boiled or sterilised) to model our teeth
• Different liquids to test – for example water, vinegar, cola, orange juice, milk
• Plastic cups or beakers
• Sticky labels or marker pens
• (optional, replace the eggs with cooked chicken bones which have been boiled and scrubbed)

How to do it

• Prior to the session, prepare the egg shells. Dispose of the white and yolk and boil the shells in water for at least 5 minutes.
• 1/3 fill each of the cups with the different liquids and label them.
• Place an egg shell into each of the cups and press it under the surface so it fills and sinks.
• Leave it for 24 hours then carefully pour away the liquids and add fresh liquid to each cup.
• Leave for a week, observing the eggshells every day. Freshen up the liquid if necessary.

What’s going on?

The drinks that have the biggest affect on the shells contain acids – juice, vinegar and cola are all very acidic. Egg shells (and teeth) contain calcium carbonate. This reacts with the acid to form carbon dioxide and a soluble form of calcium. This means that the hard shell of the egg (and teeth) dissolves, leaving only softer parts.

This video I filmed for Twig Education shows you what to do:

You can supersize this experiment by creating a bouncy egg by soaking a raw egg in vinegar for at least three days.

• Take a raw egg and carefully place it into a glass or jar
• Fill the glass with white vinegar until the egg is completely submerged
• Leave the egg in the glass for 2 or 3 days. Check the egg each day. When the egg has started to become translucent you will know it is ready.
• Remove the egg from the glass and rinse it in tap water. Whilst rinsing gently rub the outside of the egg and the white film will come off leaving you will a translucent egg.
• Examine the egg. You’ll notice that is feels rubbery (like a bouncy ball). Then lift the egg 10cm or so in the air, let go and watch it bounce.

What’s happening?

As for the egg shell experiment the vinegar begins to dissolve the shell. Eventually, the shell will completely dissolve leaving just the thin membrane of the egg. The result is an egg that looks and feels like a bouncy ball.

A Science Fair Project on Tooth Decay

Teeth Science Projects

Healthy teeth are vital when you chew food, which is important for digestion. They make it easier for our mouths to form words and – let's not forget – they make radiant smiles. Because teeth are so important, tooth decay can be a serious problem. A science fair project provides an opportunity to demonstrate how tooth decay happens and how to prevent it. You'll need to create many samples for this project, and you probably don't have a collection of teeth for them. Don't worry. Eggshells are a great substitute, and you can get as many of those as you need.

Causes of Tooth Decay

You've probably heard that sweet foods are a major cause of tooth decay, but that leads to two important questions with demonstrable answers. The first question is "Does the sugar in these foods cause the decay or is it something else?" The second question is "How do you prevent decay? "

To answer the first question, soak eggshells in a variety of solutions that may or may not cause decay. Eggshells are a good substitute for teeth because they are made from chemicals similar to those that form tooth enamel.

You can choose the solutions based on what you think are the most likely causes of decay, but one of the solutions should be pure sugar water, because you specifically want to know if sugar is the culprit. Here are some other possibilities:

• Mineral water

Let the samples sit for a week and then note the condition of the eggshells and write down the results.

You'll probably notice that the eggshells that soaked in cola and vinegar are the most affected. In fact, there may be nothing left of them. On the other hand, the eggshells in mineral water and sugar water are mostly unaffected, while those in lemonade and milk may or may not show signs of decay.

The Explanation

Dentists warn about sweet foods because sugar feeds bacteria living in a layer of plaque on the surface of tooth enamel. These bacteria create acids through their metabolism, and it's the acids that cause decay.

Cola contains phosphoric acid, and vinegar contains acetic acid. Both acids are concentrated enough to soften and partially dissolve eggshells. Sugar water and mineral water aren't acidic, so the eggshells in these liquids should be unaffected. Lemonade contains citric acid, and milk contains lactic acid, but these are less concentrated than the acids in cola and vinegar, so you may or may not see damage to the eggshells immersed in these liquids.

As a follow-up, you might let the eggshells in the milk and lemonade sit for a while longer to see how long it takes for them to show signs of decay.

Preventing Decay

Besides cleaning your teeth regularly, is there any way to prevent decay? Dentists recommend fluoride, but does it really help? Find out for yourself with eggshells and two jars filled with vinegar. Coat one eggshell completely with gel fluoride toothpaste and put it in one jar and then put an uncoated eggshell in the other jar. Watch for signs of decay on the uncoated eggshell and when you see them, note the condition of the eggshell you coated with toothpaste. If fluoride works, you shouldn't see any decay.

Follow up this demonstration by allowing the coated eggshell to remain in the vinegar to see how long it takes to start decaying.

The egg in vinegar experiment can be used as followup or in conjunction with the Egg in Soda Experiment as a way to show your child how acid interacts with calcium to cause tooth decay . Of course, putting an egg in vinegar isn't exactly the same as not brushing your teeth, but the chemical reaction caused by the two substances interacting is very similar to what happens between the acid in your child's mouth and their teeth.

• hard boiled eggs
• a clear plastic cup

Preparation Lesson

Let your child examine a hard boiled egg, even letting them smash and remove the shell if they wants. Ask them to run her tongue over their teeth and/or look at them in the mirror.

If your child doesn't already know that the hard outside of their teeth is called enamel, tell them about enamel and how it protects their teeth. Then ask:

• What does the shell do for the egg? (protects the soft inside, etc.)
• Does that remind you at all of your teeth?
• Do you remember what the soft inside of your teeth is called? (dentin)?
• Why do you think your teeth are covered in enamel?
• What would happen if the enamel was damaged or had holes in it?

Forming Hypotheses

Tell your child you're going to leave the egg in a cup of vinegar for a few days and observe what happens to it. Help them come up with a hypothesis about what they expect to see during the experiment.

Their hypothesis may be something along the lines of "the vinegar will eat the eggshell," but if they don't propose a hypothesis that fits the end result, that's OK. That's the whole point of the scientific method—to see if what you think will happen, happens and why or why not.

Perform the Experiment

• Place the hard-boiled egg in a clear cup or jar and fill it with white vinegar.
• Cover the top of the container. Explain to your child that covering the cup is sort of like leaving her mouth closed without brushing their teeth.
• Observe the egg on day one. The egg should be covered in bubbles.
• Continue to observe the egg for another day or two.
• Remove the cover from the container and drain the vinegar. Allow your child to touch the egg. The shell should be soft and pitted, if not completely dissolved.

What Happened

The bubbles you saw during the experiment are carbon dioxide, a gas that is released during the chemical reaction between the acetic acid (vinegar) and calcium carbonate of the eggshell. The acid breaks down the calcium and essentially eats away at the eggshell.

Connection to Dental Health

Your child may wonder how an egg in vinegar has anything to do with their teeth. Though it doesn't happen as quickly as the reaction between the egg and vinegar, there's a similar reaction that happens in your child's mouth.

The bacteria that live in her mouth stick to the hard surfaces of their teeth. Some of these bacteria create acids when they are combined with sugar in foods and beverages they consume. These acids can break down the enamel of their teeth if they don't brush often and be careful about how the number of sweets they eat.

Note: This experiment can be very upsetting to some children. Be certain to reassure your child that their teeth won't be "eaten" by acid if they forget to brush once in a while.

5 Science Experiments for Kids Related to Teeth

Using Engaging Science Experiments to Teach Your Child

When it comes to your child’s oral health, one of your major tasks as a parent is teaching them about the importance of a great oral hygiene routine and integrating this routine into their day. Getting your child interested in oral hygiene might feel like a struggle at first, but there are actually plenty of fun activities and experiments you can use to get your child engaged and interested in their oral health while showing just how important oral hygiene is. The lessons you’re trying to teach will better stick if your child is engaged and having fun — and it’ll be more fun for you, too! Plus, starting this process early builds healthy habits in your child and protects their teeth and gums in the long run, helping them stay healthier well into adulthood. Here are a few science experiments you can try at home to entertain, teach, and engage your little ones!

Egg Brushing

Eggshells are made from calcium, so they make an easily accessible comparison to tooth enamel for home science experiments. This experiment involves soaking hard-boiled eggs overnight in different types of liquids, including water, a dark-colored soda, and vinegar. Give your kids the chance to guess what they think will happen to each egg, then check the eggs in the morning. The egg that was soaked in soda will be stained brown, so it will look the most different visually, but the shell of the vinegar egg will be squishy!

You can explain why these changes happened and how it relates to your child’s own teeth, and then you can drive home the importance of brushing their teeth with one final step. Give your kids a toothbrush and let them try to brush the stained egg with water, then with toothpaste. While the stain won’t come off with just water, a little elbow grease and toothpaste should start to get the egg clean. It’s a great way to show your kids how much the foods and drinks they consume can change their teeth and how important brushing their teeth with toothpaste really is!

Revealing Plaque

Plaque is usually pretty hard to spot while it’s on your child’s teeth, so it’s often hard for children to relate to the need to get rid of it. After all, seeing is believing, and your kids can’t see the problem you’re talking about! Thankfully, there’s some very fun and eye-opening science experiments you can do at home to help your child see the plaque on their teeth. Disclosing tablets are chewable tablets that turn the plaque in your children’s mouths bright colors. Your children will love the colors, but it’s also a great way to help them relate to and better understand the importance of good oral hygiene.

Since chewing the tablets before they’ve brushed their teeth will make it easier for your children to locate and clean all the plaque from their mouths, this experiment can also help them learn to be more thorough during their oral hygiene routine. Using a tablet after they’ve already brushed their teeth can also reveal spots they’ve missed, helping them to go back and get those spots more thoroughly. Whether you use it as a one-time experiment or regular aid to help your child learn to brush their teeth better, it can be both a fun and educational activity that helps them improve their oral hygiene routine.

Homemade Toothpaste

Making toothpaste with your kids is a fun way to get them involved in their oral hygiene routine. Plus, just like any time you make something with your kids, it’s a great opportunity for bonding time. It’ll feel more like a fun craft or cooking project for your kids than it will a science experiment or a learning experience! There are plenty of homemade toothpaste recipes, including several specifically meant for kids and designed to taste better to them, so you can pick a recipe that sounds good to you. While you make the toothpaste, you can explain why different ingredients are going in it or talk about how toothpaste helps keep teeth healthy. Working with measurements even allows you to fit in a little practice with numbers or math concepts for your little ones, so this can be a fun but very educational activity for your kids!

Growing Plaque

We always tell kids that bacteria feed on sugar, but this science experiment is a great way to show them just how big of an impact sugar can have! It’s also an incredibly simple experiment that can be done with ingredients you likely already have at home. All you need to do is mix warm water and yeast in two cups, then add sugar to one of the cups. Be careful to stir the mixtures with different spoons so that no sugar makes it into your sugar-free mix. As you mix the ingredients, you can explain that like the bacteria in your mouth, yeast thrives off of sugar. Then all you have to do is wait and watch! The cup that has sugar in it will foam a lot, potentially even overflowing. Seeing this reaction can help show your child what’s happening in their mouth, even if they can’t see it. You can then explain how flossing and brushing their teeth protects their mouth from bacteria and keeps their teeth healthy.

Elephant Toothpaste

Making “ elephant toothpaste ” doesn’t provide a result that your kids can use to clean their teeth — it just creates a fun chemical reaction that results in foam. When you create this mixture in a bottle, the foam erupts from it in a way that looks like toothpaste being squeezed from a tube. It’s still an incredibly fun experiment that provides an opening for you to talk about toothpaste and how it helps keep teeth healthy. It also has value in the way it’s able to also teach your child about science and chemical reactions. Younger kids will simply think it’s cool that the bottle heats up as the foam begins to form, but you can explain this chemical reaction in a little more detail to slightly older kids. The yeast works as a catalyst to separate the oxygen from the hydrogen peroxide and produce heat in the process, making the result a great example of an exothermic reaction. Your kids will have a blast with this experiment while learning about both science and oral health!

Children learn best when they’re engaged and having fun, so these science experiments allow you to meet your children at their level. Your kids will have a blast, but they’ll also be able to learn through experiencing the concepts you’re talking about, giving them a better long-term understanding of just how important it is to take good care of their oral health. Your children will carry this understanding and the related habits you’ll help them form into adulthood, impacting their oral and overall health for a lifetime.

Egg and Toothpaste Experiment (Learn Importance of Brushing Your Teeth)

• November 4, 2020
• 3-4 Year Olds , 5-6 Year Olds , 7-9 Year Olds , Rainy Day Science

This wonderful experiment using eggs and toothpaste helps parents and teachers to teach children how important is brushing teeth.

Most parents out there have had difficult times to make your child’s brushing time fun and excited!!

Also, many parents experienced annoying times to stop their kid from grabbing artificial sweeteners like soda, candies, etc.

If you are one among such parents whose warnings just remain as warnings which are not put into serious action by your child, here is the super-fun activity for you!

Egg and Toothpaste Science Activity

Objective: To observe how eggshell is protected by tooth paste and learn how tooth reacts to acids and stain.

Time: The activity requires 24 hours to show stain on eggs.

Inspiration: One day, my younger daughter (who is 5 years old) came up with a question “Mumma! How come our teeth becomes stained and turn into yellow colored?”

Immediately, I asked her what is wrong with her teeth.

She replied, “Mumma! I am completely fine but today in my school, one of my close friends was suffering from teeth pain and I observed her teeth were yellow tinted.”

Then, I understood the complete picture and turned her question as a great opportunity to show her how important is brushing our teeth using toothpaste.

For this activity I used eggs and toothpaste to show her importance of brushing.

Why eggs? Eggshells are having the same material as of our tooth and bone composition. So, eggs make a great ingredient in this activity.

Appropriate For Age Group: this fun science investigation is perfect for preschoolers, kindergarten, and elementary children. Toddlers can enjoy and try to understand the results but they may not exactly know the science involved in this experiment.

Materials Required: For your surprise, this super cool egg and tooth paste science activity requires 3-4 ingredients from the fridge of your kitchen. Do you want to know what those simple supplies are!? Have a look here:

1) 4 plain and raw eggs

2) Tooth Paste (any kind of toothpaste right in your home is fine)

3) Coca Cola

4) Black Coffee

That’s it! Just collect these items from your kitchen and get ready at the experiment table to investigate eggs and toothpaste hands-on.

Simple Step-by-Step Instructions

This fun science investigation takes a few minutes to finish but we need to wait for a day or 24 hours to see the spectacular results. So, plan accordingly if you want to perform this activity either at home or in a school event.

Let us jump into the simple instructions and follow the same while experimenting with eggs and toothpaste.

Step-1: Do little Preparations

Before you start this activity, you need to help your children in making black coffee.

If your children are too young to manage burners, then prepare black coffee and directly offer them to use in the activity.

And keep four neatly cleaned transparent glasses ready! Also make sure the eggs you picked up are in good condition that means there is no breakage or leakage of egg inside contents.

Because leaking egg can damage the whole experiment results and looks messy too!

Step-2: Keep the eggs ready for the Experiment

Bring the eggs to the room temperature in order to achieve appropriate outcome.

Once you check the eggs are in good condition, ask your child to wash the eggs carefully with neat hands. And then let them dry the wet eggs using paper or cloth napkins.

That’s all! Your eggs are ready to go on to the experiment table.

Step-3: Cover the eggs with Toothpaste  

Ask your child to coat two plain eggs with good amount of toothpaste evenly. And the rest two eggs remain as it is. That means we are not coating these eggs with any other material.

Step-4: Arrange the Glasses for Experiment

Now pick four transparent glasses and fill two glasses with coke and the other two glasses with black coffee.

Make sure you are placing these glasses on a plain and flat surface such that you can avoid unnecessary disturbances and messy work during investigation.

Also, remember to fill the glasses with the respective liquids in equal amounts. If you want, you can measure and pour the liquids in to the glasses to keep the quantity equal.

Step-5: Drop the Eggs

It is time to drop the eggs into the liquids for investigation! Pick one plain egg and one toothpaste coated egg and drop them in coke filled glasses respectively.

After that pick another set of eggs i.e. one plain egg and one egg covered with toothpaste and drop into the two glasses filled with black coffee respectively.

Step-6: Allow the set-up for a day

This is so simple and easy step where you have nothing to do or investigate! Yes, ask your children to leave the experiment set-up for 24 hours completely to see the fascinating results.

Step-7: Observe the Results

Are you done waiting for 24 hours to see the outcomes? Here are the results we experienced after a long wait of 24 hours. Hahaha! Yes, waiting for 24 hours is a long wait for children to see the results.

I am attaching the results table and pictures for your reference. Just compare and see whether you also experienced the same.

Glass-1 filled with coke and plain egg got stains where the one coated with toothpaste and dropped in glass 2 with coke does not have any stains.

In the same way, the plain egg dropped in black coffee showed stains whereas the egg coated with tooth paste does not show any stains. You can see the pictures attached for your reference.

Science behind the Egg and Toothpaste Activity

Egg shell is the rich source of calcium carbonate whereas black coffee and coca-cola are acidic in nature.

When the plain egg dropped in the coke and black coffee, the acidic contents immediately start reacting with calcium carbonate and forms stains.

As this is a slow process we are letting the experiment set up for 24 hours to see best results. On the other hand, the eggs coated with toothpaste, when dropped in the coke and black coffee, the fluoride in toothpaste build a protective layer between the eggshells and acidic solutions.

The fluoride in toothpaste makes the eggshell stronger and protects it from reacting to acidic contents of coke and black coffee.

Fluoride is the natural mineral helps the outer layer of eggs and teeth become stronger naturally.

Egg-Toothpaste Science Experiment and Importance of Brushing Teeth

Eggshells denote the teeth of humans as the outer layers of both made of same material i.e. calcium. And the chemical composition of eggs, bones, and teeth are same.

So, we are representing eggshells as teeth. Coke and black coffee represents the acids caused due to bacteria in the form of plaque. Plaque is the result of constant consumption of artificial sweeteners.

So, when we brush our teeth properly using toothpaste, the fluoride content in it helps teeth from the damage of acids, cavities, stains, and plaque.

This is how we can explain and give a great demonstration on importance of proper brushing teeth with fluoride contained toothpaste.

The fluoride content in toothpaste keeps the eggshells safe from the acids present in black coffee and coke. Hence, the toothpaste acts as a strong protective layer between the acids in coke and calcium content of eggshell respectively.

Liquids rich in acids are the best liquids to dissolve egg shells. For example: Orange Juice, Vinegar, Coke, Black Coffee, and other acidic liquids. The acids in these liquids react with calcium carbonate in egg shells. Carbon dioxide is the gas released during this reaction. If you let the reaction to continue for long hours, you can observe acids dissolving the egg shells gradually and completely. Finally, the reaction leave the egg to uncover its outer layer and exposes inside contents.  

Osmosis is the process through which sudden drive of solvent particles happen from less concentrated solution to high concentrated solution. This is the same happens when you place an egg in pure water for 24 hours. The water travels from outside part of the egg through the semi-permeable membrane to the inside part of the egg. You can observe osmosis when the egg swells up after sometime the egg put in the water. Otherwise, add some food color to the water and let the egg sit for a day. You can easily observe the transmission of water through the color travel from outside to inside part of egg.  

Take a glass of coca cola and place an egg in it. Let it remain in the coke solution for 24 hours. Then, take out the egg and you can see the egg is stained. This is because the acid the coke reacts with calcium in the egg shell.

Absolutely yes! Coke contains dissolving agent in it i.e. acidic nature, which is why the egg shells dissolves completely when an egg is placed in coke solution and left for long hours. The egg shell is nothing but calcium carbonate which softens and melts on long exposure to acidic solutions like coke. You can observe this amazing chemical reaction by witnessing the carbon dioxide gas releasing as a result of reaction in the form of tiny bubbles.

5 More Toothy Science Experiments to Do With Your Kids

Plaque Attack and Other Fun Dental Experiments for Kids

If you’re looking for toothy science experiments for kids, Must Love Kids Pediatric Dentistry has got some great resources for you. Check out these 5 fun science projects or keep reading for a step-by-step guide on how to set up a plaque attack and other fun dental experiments for kids.

1. Apple Cavity Experiment

Want to show your kids the problems cavities cause when we don’t take care of our teeth? Start with this simple apple cavity tooth science experiment.

• A sharpened pencil
• 3 paper bags
• A sharp knife

Instructions:

Step 1: Take one apple and use the sharpened pencil to make five to 10 holes in it. Poke only one hole in the second apple and use the third apple as the control.

Step 2: Put the apples in separate paper bags and let them stay there overnight.

Step 3: Use a sharp knife to cut all the apples in half.

The control apple will appear normal, while the apples with holes in them will have turned brown, an early sign of decay.

Explain to your kids how the skin of the apple protects the insides, and when it’s compromised (like with a punctured hole), the whole fruit begins to rot, just like with our teeth. The hard outer surface of our teeth, the enamel, can only protect our teeth if it remains intact. Any break in the enamel may allow bacteria to accumulate and cause the development of cavities.

2. Plaque Attack Experiment

Now this may just be our favorite tooth science project here at Must Love Kids Pediatric Dentistry. Your little one gets a front row seat to the Plaque Formation Show, experiments like this one may just be gross enough to nudge them onto a path of good oral hygiene.

• 2 cups of warm water
• 4 tsp of yeast
• 1 tbsp of sugar
• 2 plastic spoons

Step 1: Use separate spoons to add 2 teaspoons of yeast into each cup of warm water.

Step 2: Pour 1 tablespoon of sugar into one of the cups and stir the mixture. Remember to use different plastic spoons for each of your cups.

A brown foam will start coming out of the cup you added sugar into. Ask your kids to try and guess why this did not happen in the other cup.

As you discuss the experiment with your little Isaac Newton, talk about how sugar in our mouth also creates plaque , and if this sticky fluid is not removed through proper brushing and flossing twice a day, it can lead to tooth decay or even gum disease.

3. “Think Before You Drink” Experiment

Soda pops, energy drinks, and apple juice. Most of our patients here at your favorite kids’ dentist (Must Love Kids Pediatric Dentistry) love either all three or at least one. Some maybe even love these drinks a little too much. If that’s true for your family, try the Think Before You Drink tooth science experiment. It can help show your kids how much hidden sugar is in such drinks and how it can damage your teeth.

• 6 clear disposable cups
• 3 soft drinks (e.g soda pop, energy drink, and a juice box)
• A bowl of sugar
• A permanent marker

Step 1: Use the permanent marker to label three cups with the names of the soft drinks you chose for this tooth science project.

Step 2: Read the label for each soft drink to find out the total grams of sugar in each. Divide this value by 4.2 to find out the number of teaspoons of sugar in each drink. Record your values in the notepad.

Step 3: Add the number of teaspoons of sugar you found in step 2 into the labeled cups and set it aside.

Step 4: Use the permanent marker to label the remaining three cups with a drink name and place each cup in front of its corresponding soft drink.

Step 5: Ask your child to add the amount of sugar they think is in each soft drink into the cup in front of it.

Step 6: Bring out the cups you placed aside that had the actual amount of sugar in each drink and compare the two sets of cups.

Did your little one guess higher or lower than what was actually in the drink? We often don’t realize how much sugar is in our drinks . But such hidden sugars in drinks are just as bad for our teeth as candy and chocolate is. Brainstorm with your child on how you can make healthier drink choices. Some great options would be to switch soda pop for milk and energy drinks with vegetable juices that are low in sugar.

4. Flossing Experiment

Flossing involves a lot of hand-eye coordination that can be hard to master for our kids, especially the younger ones. Doing experiments that involve flossing will help your child get some practice in. This tooth science project is a great hands-on activity to explain flossing and also learn why it’s an important part of any good oral hygiene routine .

• Jar of peanut butter or any other sticky food product
• Rubber glove
• Toothbrush and toothpaste
• Dental floss

Step 1: Put the glove on your hand. Spread your fingers apart and ask your child to smear peanut butter on every side of your fingers.

Step 2: Put your fingers together. Add toothpaste to your toothbrush and let your child try to brush the peanut butter away. Make sure you don’t separate your fingers throughout the process.

Step 3: While still pressing your finger firmly together, ask your child to use dental floss to clean the area between your fingers.

Even after cleaning the glove with a toothbrush and toothpaste, the dental floss still comes out with peanut butter on it.

Explain to your child that your fingers represent your teeth, and that no matter how great you are at brushing, peanut butter (or any other food particle) can still remain in the space between the teeth. That’s why it’s important that we also floss, so we can clean the places where a toothbrush can’t.

5. Egg Carton Toothbrush Painting Activity

Another tooth science project our Must Love Kids Pediatric Dentistry patients love doing is the egg carton toothbrush painting activity. It’s a fun, hands-on activity that teaches kids the importance of brushing and flossing. And as an added bonus, it takes less than five minutes to set up.

• White Styrofoam egg carton
• Washable tempera paint (you can choose any color)
• 2 toothbrushes
• 12-inch string
• Bowl of water
• Toothpaste (optional)

Step 1: Flip the egg carton so the bumps are on top. Use one of your toothbrushes to paint the dips and bumps as well as in between each egg space. Let it dry.

Step 2: Dip the other toothbrush into your bowl of water. Add toothpaste onto the bristles and start brushing the egg cups to try and remove the paint.

Step 3: Next, use the string to remove any leftover paint in the space between each egg space.

Step 4: Rinse your egg carton in the bowl of water, and if there’s any leftover paint on the egg carton, repeat steps 2 and 3.

Using an egg carton allows your child to visualize the different areas of teeth that we need to clean on a daily basis. As you paint the dips and bumps and try to remove the paint between each egg space, your child starts to understand how it’s easy to miss some places if you’re not careful.

Have fun with these fun science experiments!

Try any of these 5 toothy science experiments on this list and let us know how it went through our Facebook page or during your next dental appointment at our Vancouver office. We look forward to seeing your smiles.

What Do Sugary Drinks Do to Your Teeth? - Kids Science Experiment

I hope you will enjoy this fun science experiment for kids. With some basic materials and a day of waiting, you can show your children what drinks like soda pop and fruit juice to do to their teeth and give them an idea of how important it is to brush every day.

My kids are pop fiends. (I know some of you are confused right now because you call pop soda .)

Probably because I am a pop fiend. They learn what they see, right?

It's not one of our finer points.

Anyway, I wanted to show the girls what pop does to their teeth because they are both kind of in a funk where they don't want to brush without a lot of prompting.

So we talked about how your tooth enamel is made of the same basic stuff (calcium) as eggshells (calcium carbonate, I think), and so we could soak some eggs in drinks that we like to see what would happen to them over time. The discoloration of the white egg would be similar to the discoloration of our white teeth over time.

The effects of different drinks, as you can see above, were striking. The kids, Allie especially, really got the idea that these drinks are harmful to her teeth, and she has since been brushing every day without any fuss.

• 5 raw white eggs - Actually, they don't have to be raw, but they also don't have to be cooked, so I don't know why you would spend the time.
• 5 cups - I thought about buying clear plastic cups, but the liquid is dark, and you can't see the eggs anyway, so use whatever cups you already have.
• Masking tape
• A dark-colored sugar-free drink like Gatorade G2 or a diet soda
• A dark-colored fruit juice like grape juice
• A dark-colored flavor of regular soda or pop - we used black cherry but a cola like Pepsi or Coke would probably work better
• Orange juice (We only had 4 eggs left in the house, so we omitted orange juice, but I was really interested in what would happen with this. My dentist told me that orange juice is pretty close to the worst drink possible for my soft teeth because the acid attacks the enamel and the dentin inside.)

Instructions

• This one is super easy.

• Store your cups in a safe spot.
• Wait. Check your cups after a few hours if you want. We checked ours before we went to bed and then took them out after about 24 hours.

The Science

The hard shell of an egg protects the soft parts inside, just like the hard enamel on your teeth protect the soft and tender pulp on the inside. Both eggshells and teeth are made of calcium, a hard white substance that also makes up our bones.

Sugar and acids are very harmful to teeth. Acids actually dissolve the enamel, giving bacteria an inroad to begin decaying it, and sugar promotes tooth decay (cavities).

Of course, the water egg was the best after 24 hours. But take a look at the Gatorade egg:

There was definitely a yucky-looking purplish coating on the egg, but it was fairly easy to wipe off with just our fingers. Unfortunately, the slime made the egg slippery and it fell on the floor before I was able to photograph it with the other eggs (in case you were wondering why there were only 3 eggs in the photos, now you know).

This was the black cherry pop egg:

And this was the grape juice egg: (I love the shock on Allie's face here.)

A study published in the journal  General Dentistry found that pop is actually ten times more harmful in the minutes after drinking than is fruit juice. Our experiment showed that the discoloration from grape juice was a lot worse and longer-lasting, but it's not likely to cause actual decay as quickly as the pop would. So that part of the experiment was a little confusing.

The bottom line is that the sugar, color, and acids in our drinks harm our teeth, and those effects are exacerbated by poor brushing habits.

Extend the Experiment

Take this experiment a step further by brushing the eggs with a toothbrush and then with toothpaste and a toothbrush, to see how much of the stain can be removed from the egg and how much is left. It takes a lot longer than you think to clear away the stain, and you will probably find (as we did) that a lot of the stain is permanent.
