What are teeth made from?

Browse → Human Body → Outside the Body

What do you think your teeth might be made from? Because they need to be hard and tough so you can chew, teeth are made from some pretty strong substances!

On the very outside of your teeth is something called enamel. Enamel is the hardest material in the entire body! Below the enamel is a part of the tooth known as the dentin, which is mostly made up of hard minerals like calcium. (You might know calcium as the good-for-you ingredient that gives milk its white color.)

These two tough layers protect some more delicate parts further inside of your teeth: the pulp. A tooth’s “pulp” contains nerves and blood vessels. The blood vessels help bring important things to your teeth, like nutrients and oxygen. The nerves help alert you of any problems your teeth might be having, so you can take good care of them right away!
