A tooth (plural teeth) is a undersized, calcified, whitish structure initiate in the jaws (or mouths) of many vertebrates and habituated to to sever down food. Some animals, particularly carnivores, also partake of teeth for hunting or in place of defensive purposes. The roots of teeth are covered by gums. Teeth are not made of bone, but degree of multiple tissues of varying density and hardness.
The ordinary make-up of teeth is alike resemble across the vertebrates, although there is sizeable modulation in their fabric and position. The teeth of mammals have deep roots, and this pattern is also rest in some fish, and in crocodilians. In most teleost fish, however, the teeth are spoken for to the outer outside of the bone, while in lizards they are attached to the inner side of the jaw by way of a man side. In cartilaginous fish, such as sharks, the teeth are seconded beside rough ligaments to the hoops of cartilage that form the jaw.
