Composition: Enamel is about 96% mineral, which is what gives it its incredible strength and durability. The remaining 4% consists of water and organic material.
Function: It acts as a protective hard shell for the inner, more sensitive parts of the tooth (the dentin and pulp) against the physical and chemical demands of chewing and acidic foods.
Durability: Unlike bone, enamel does not contain living cells and cannot regenerate or repair itself if it is chipped or decayed.
