Dental Care Day 2: Types of Teeth

Types of Teeth
Read: All About Teeth by Mari Schuh and Snacks for Healthy Teeth by Mari Schuh

Discuss: Humans have 20 baby teeth and then at age 6 or 7 they begin to fall out and we get 32 permanent teeth. There are 206 bones in your body. Of those 206 bones, which are the hardest ones? Yes, teeth are the hardest bones in the human body. If teeth are so hard and strong, then why do they decay and break? Well, it’s because of the germs. We get germs in our teeth when we eat, so we must brush our teeth every day.

Canine- 1 next to each outside incisor for tearing
Molars- the back teeth for grinding
