In mammals, the teeth are divided into four types: incisors, canines, premolars, and molars. Omnivores, herbivores, and carnivores have different forms and numbers of these teeth. Carnivores'incisors are short but sharp for scraping meat off bones. Their canines are enlarged for killing their prey. The premolars and molars are jagged for tearing apart flesh.
