How a Tooth Decays
You've probably gone to the dentist before and had to wait in the waiting room with several other people. Well have you ever wondered why all those people are there? This project helps you to understand the process that causes a tooth to decay. You will also learn to protect your teeth and prevent tooth decay.
 Material and instructions
You collect some information, do a few experiments and make a display for your presentation. It will take one to three weeks to complete this project, but it is worth the time. You will need to write a report about your findings. For your display you may also make a large model of a tooth and paint it to show what areas of a tooth are at risk for a cavity.
