(NAPSI)—Each smile is unique. What does yours say about you?
Your Teeth Tell Your Story

The crowns and roots of your permanent teeth form beneath your baby teeth, eventually pushing them out of the way and triggering a visit from the Tooth Fairy.
Teeth Survive Long After Death
The enamel on teeth is stronger than any other part of the body—so strong that it can remain intact for hundreds of years after someone dies. Studying the teeth of human ancestors has taught scientists some fascinating things about history.

Even the toughest substance in the body needs regular care, however.
