Why do we use eggs for teeth in an experiment?

Why do we use eggs for teeth in an experiment?

The idea behind this tooth decay experiment is simple – eggshells are like teeth enamel. When eggshells come in contact with these drinks and beverages for a long time, they get eaten away, just like tooth enamel.

What happens when you put toothpaste on an egg and leave it for 24 hours?

What happens when you put toothpaste on an egg? The fluoride content in toothpaste keeps the eggshells safe from the acids present in black coffee and coke.

What happens when you cover an egg with toothpaste?

The eggshell is half coated in toothpaste. The calcium fluoride in the toothpaste protects this half of the eggshell in the same way that toothpaste protects our teeth. Safety: This experiment should NOT be carried out if anyone has an egg allergy.

How does an egg shell compare 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.

How different liquids affect teeth?

Anything that measures 5.5 or less on the pH scale is considered acidic – the lower the number the worse. The acidity in these drinks softens tooth enamel, making teeth vulnerable to decay and cavities. Sodas, sports drinks, energy drinks, iced and sweet teas, and fruit juices all have high acid levels.

How sugary drinks affect teeth experiment with eggs?

Eating/drinking sugary drinks causes naturally occurring bacteria in our mouth to produce acids which can eat away at our teeth and result in erosion or dental decay. In this experiment, we use the hard egg shell to demonstrate the properties of tooth enamel.

What is the conclusion of the bouncy egg experiment?

Conclusions. The eggshell is dissolved because vinegar is an acid and eggshells contain calcium carbonate, which is a base. When these two chemicals are combined, a chemical reaction occurs. Carbon dioxide is formed, which is why you see the bubbles.

How do you make eggs clear and bouncy?


  1. Fill your container with about 1 cup of vinegar.
  2. Add about 10 drops of food coloring of your choice.
  3. Carefully place a raw egg inside each jar.
  4. When the surface of the water has a weird scummy film, the eggs are ready to take out.
  5. You can gently roll and bounce the eggs to see what happens!

How do different liquids affect egg shells?

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.

What material is closest to teeth?

They actually have extremely similar chemical make-ups. Eggshells have a similar chemical composition to our tooth enamel, making them react similarly with other chemicals.

What happens to egg when placed in vinegar?

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!

What conclusion can you make on the effect of sugary drinks on teeth?

Sugary beverages are not good for teeth as they stick to the surface and bacteria then break down the sugar to make acid, which can damage teeth. When tooth enamel is exposed to acidic beverages or acid generated by sugary beverages, it softens and loses some of its mineral content.

What is the tooth egg experiment?

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.

Which acid is represented in the tooth egg experiment by Vinegar?

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.

What grade level is a tooth decay egg?

At Home Science Experiments Tooth Decay Egg Experiment Grade Levels: 1-12 Tooth enamel is tough but can be eroded by sugar in your beverages and acids in your mouth. Sugary beverages are not good for teeth as they stick to the surface and bacteria then break down the sugar to make acid, which can damage teeth.

Can egg shells teach us how to keep our teeth healthy?

This fun tooth decay experiment with egg shells is all about teeth and how to keep them healthy. First we talked about how important it is to brush teeth everyday and then chatted about foods that are good for teeth and foods that aren’t.
