10 Interesting Facts about Teeth

One of these following facts about teeth might give you much information about it. Teeth (pl) are small, calcified, whitish structure found in the jaws (or mouths) of many vertebrates and used to break down food. Some animals, particularly carnivores, also use teeth for hunting or for defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but rather of multiple tissues of varying density and hardness. The cellular tissues that ultimately become teeth originate from the embryonic germ layer, the ectoderm. To get to know more about teeth, here are some other facts about teeth you might be interested in.
