Teeth Alive?

Teeth are alive right, not just the nerve inside? Made of cells, but are all the cells alive, even the outer surface?

Enamel's primary mineral is hydroxyapatite, which is a crystalline calcium phosphate. The large amount of minerals in enamel accounts not only for its strength but also for its brittleness . Dentin, which is less mineralized and less brittle, compensates for enamel and is necessary as a support.

Unlike dentin and bone, enamel does not contain collagen. Instead, it has two unique classes of proteins called amelogenins and enamelins. While the role of these proteins is not fully understood, it is believed that they aid in the development of enamel by serving as a framework support, among other functions.
