What are teeth?
Teeth are a part of your digestive system.  They are used to mash and grind food to allow your digestive system to be able to process it into nutrients and energy for the body.  Most humans have 32 teeth, and enamel is the protective outer layer of the teeth.  Teeth attach the the mandible bone and are very strong.  If you eat a lot of sugar the enamel on the teeth will break down causing cavities that have to be fixed and repaired at the dentist.
