Why are teeth not considered skeletons?

Teeth, like bones, contain calcium, phosphorus, and other minerals. But there's one substance that teeth don't have—collagen. Collagen is a type of protein, considered as “the glue that holds the body together”.

Why are everyone's teeth so white?

Enamel is mostly made up of calcium phosphate, a naturally white, rock-hard mineral, giving our teeth their white colour. Tooth enamel is the hardest substance in the human body and should last a lifetime. However, the outer layer of enamel can become damaged or worn down, particularly if you eat a lot of sugary foods.

Can yellow teeth become white again?

Can you get DNA from ivory?

Do teeth really have skin?

Microscopic bacteria in your mouth form a film (or skin) on the teeth. When it is so thin that it is barely detectible, it is called biofilm. When it gets thicker, it is called plaque.
