What are your teeth made out of?

Answer 1

A tooth is not at all a bone and it is not even really like bone. Teeth are made by cells called ameloblasts and odontoblasts. The main mineral content is called "hydroxyapatite," which is a form of calcium crystal.

If you put the following words in any search engine, you will get thousands of references telling about how teeth are formed:

ameloblast, odontoblast, (osteogenesis -imperfecta)

Answer 2

There are 2 parts to a tooth. The exposed part protruding from the gum is the "crown". What's buried under the gum is called the "root". Under the crown there are 3 parts, from outer to inner - enamel (white, hardest, with the highest mineral content), dentin (yellowish, softer, lower mineral dentin but more like shock absorber), then there's an inner pulp chamber containing blood vessels, nerves and tissues which nourish the tooth and surrounding periodontal ligament and gingiva. In the root part, the outer layer is called "cementum", then again dentin and pulp on the inside.

Answer 3

Teeth have different layers. The outer layer is called enamel. Then just under that you have the dentin. You also have nerves.

Does that answer your question?

Answer 4

HELLO,
DR. SAM IS ABSOLUTELY CORRECT IT'S HYDROXYAPATITE CRYSTALS WHICH ARE THE UNDERLYING STRUCTURE OF TEETH. IF CAN ONLY ADD, A TOOTH IS NOT A DEAD HARD STRUCTURE, BUT A LIVING BODY PART COMPLETE WITH ITS OWN BLOOD AND NERVE SUPPLY.
