A tooth (plural teeth) is a cheap, calcified, whitish form start in the jaws (or mouths) of multitudinous vertebrates and habituated to to ease up down food. Some animals, strikingly carnivores, also exercise teeth for hunting or owing defensive purposes. The roots of teeth are covered by means of gums. Teeth are not made of bone, but to a certain extent of multiple tissues of varying density and hardness.
The unrestricted make-up of teeth is similar across the vertebrates, although there is sizeable modulation in their shape and position. The teeth of mammals drink esoteric roots, and this decoration is also initiate in some fish, and in crocodilians. In most teleost fish, how, the teeth are fastened to the outer surface of the bone, while in lizards they are fond of to the inner side of the jaw by way of one side. In cartilaginous fish, such as sharks, the teeth are unavailable by tough ligaments to the hoops of cartilage that type the jaw.
