A tooth (plural teeth) is a undersized, calcified, whitish build ground in the jaws (or mouths) of multitudinous vertebrates and occupied to sever down food. Some animals, particularly carnivores, also take teeth for the purpose hunting or instead of defensive purposes. The roots of teeth are covered nearby gums. Teeth are not made of bone, but degree of multiple tissues of varying density and hardness.

The community make-up of teeth is similar across the vertebrates, although there is of distinction modulation in their show up and position. The teeth of mammals be struck by deep roots, and this design is also initiate in some fish, and in crocodilians. In most teleost fish, manner, the teeth are attached to the outer outwardly of the bone, while in lizards they are fixed devoted to to the inner surface of the jaw alongside the same side. In cartilaginous fish, such as sharks, the teeth are seconded by means of tough ligaments to the hoops of cartilage that accumulate the jaw.
