Incisor Tooth

In mammals, the incisor teeth are the flat teeth at the front of the jaw.

In many herbivores and omnivores, they are adapted for shearing sharply, whereas in felids the incisors are small, as meat is bitten off with the canines and carnassials.

In elephants, the upper incisors are modified into curved tusks and in narwhals one incisor develops into a straight, twisted tusk.

Rodents have incisors that grow throughout their lifetime and they are worn down by gnawing.
