The Erosion of Tooth Enamel

The Erosion of Tooth Enamel | Science Fair Projects | STEM Projects
Have you ever wondered if drinking soft drinks can cause tooth erosion? In this science project, you will find out if immersing teeth in soft drinks can cause them to lose weight.


The hypothesis is that immersing teeth in soft drinks will cause tooth erosion and the teeth will lose some of their weight.

Method & Materials

You will fill three bottles with different soft drinks, wash and clean three teeth, and place a tooth in each bottle. After the first day, remove the teeth from each bottle and check their weights. Repeat this process every day for the next four days.
You will need three transparent bottles, one bottle of Coca Cola, one bottle of Sprite, one bottle of root beer, one digital weighing scale, and three teeth of identical size and weight.


The results showed that all the teeth immersed in the soft drinks lost some weight daily. The tooth that was immersed in Coca Cola lost the most weight and the tooth that was immersed in root beer exhibited the least erosion.

Why do this project?

This science project is interesting because it shows the effects of soft drinks on tooth enamel. It also shows how different types of soft drinks can have different effects on teeth.

Also Consider

Experiment variations include testing the effects of soft drinks on other calcium-rich materials, such as pieces of chalk, and testing the effects of fruit juice on tooth enamel.
