Its always necessary keep your teeth clean
A tooth (plural teeth) is a mignonne, calcified, whitish form initiate in
the jaws (or mouths) of multitudinous vertebrates and used to defeat down
food. Some animals, explicitly carnivores, also exercise 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 fairly of multiple
tissues of varying density and hardness.
The general structure of teeth is alike resemble across the vertebrates,
although there is sizeable converting in their show up and position. The
teeth of mammals drink profound 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 surface of the bone, while in lizards they are
fond of to the inner side of the jaw by way of a man side. In cartilaginous
fish, such as sharks, the teeth are seconded by means of tough ligaments to
the hoops of cartilage that type the jaw.
