What are teeth made of?

Around the very outside of your teeth is enamel. Enamel is the most robust material in the entire body. Enamel is mostly fabricated of calcium phosphate, which is a tough mineral. Beneath the enamel is a part of the tooth called dentin, which is the layer comprised of the majority of your tooth structure.

No bones about it, teeth are of many tissues of varying density and hardness. The cellular tissues that eventually become teeth generate from the embryonic germ layer, known as the ectoderm. The general structure of your teeth is similar across the vertebrates, although there is considerable variation in their form and position.
