What can you substitute for teeth in an experiment?
This Catalyst article describes an experiment with fluoride toothpaste on eggshells (as a substitute for teeth). Both teeth and eggs contain calcium compounds which can be attacked by acid. When an egg is put in vinegar the shell is weakened by the acid making it soft and more fragile….An Eggsperiment on Teeth.

What objects are similar to teeth?
Eggshells are similar to tooth enamel. They share the same coloring, ranging from a light yellow to white. In addition, the eggshell protects the egg from breaking, just as tooth enamel protects the tooth from decaying.
Why can eggs represent teeth?
Eggshells have a similar chemical composition to our tooth enamel, making them react similarly with other chemicals. This can help us understand what stains tooth enamel. When we brush an eggshell with fluoridated toothpaste, it strengthens the shell and protects it from acid, just like it does for our tooth enamel.
Why are eggs and teeth similar?
Egg shells are made of calcium carbonate – a hard mineral that is similar to calcium phosphate, the substance our teeth are made of. Acids react with calcium carbonate, breaking it apart into calcium (which is carried off in the water) and carbon dioxide gas.
Which liquid causes teeth to decay fastest?
From this unique experiment we have discovered that coke cola rots teeth the fastest. Apple juice came 2nd because Apple juice has natural sugars which rot teeth.
How do you check enamel on teeth?
Tooth enamel is tough but can be eroded by acids in your mouth. Test the acid levels in your favorite drinks with pH test strips, then soak shark teeth or eggshells in each drink to see if the acid weakens tooth enamel. Try it!
What qualities do eggs share with human teeth?
Eggs share similar qualities with human teeth, which makes them a good model for this experiment. The texture of the tooth enamel and the egg shell are similar; both are calcium-rich and have a protective function. Coco Cola, Hi-C, and water are common drinks that have different effects on teeth.
Can egg stain teeth?
Eggshells and teeth have entirely different functions, so it’s difficult to see what they have in common unless we take a look at how they are made. Eggshells have a similar make-up to our tooth enamel, making them react similarly with other foods and beverages. This can help us understand what stains tooth enamel.
What liquids dissolve eggshells?
vinegar react with eggshells and make them dissolve, leaving the inside of the egg intact.
Is sugar or acid worse for teeth?
These acids chip away at the outer layer of your teeth, weakening it and making you more prone to cavities or cracked teeth. So while it’s not entirely true to say that food acids are worse than sugar, they can have effects on your teeth that are just as serious.
What foods make teeth whiter?
Foods That Whiten Teeth Naturally
- Strawberries. They may stain your shirt, but they could work to whiten teeth, since they contain an enzyme called malic acid.
- Apples, celery and carrots.
- Oranges and pineapples.
- Baking soda.
- Yogurt, milk and cheese.
What does vinegar do to eggshells?
If you soak an egg in vinegar the eggshell will absorb the acid and break down, or dissolve. The calcium carbonate will become carbon dioxide gas, which will go into the air. What is left is the soft tissue that lined the inside of the eggshell. It will bounce!
How do you make a bouncy egg with water?
Place the boiled egg in the bowl. Completely cover the boiled egg with vinegar. After three days, remove the egg from the jar. Gently rinse the shell off the egg with tap water.
