The function of the teeth labelled X is for tearing and grasping. The teeth labelled X are the canine teeth, which are the sharp, pointed teeth located next to the incisors in both jaws. The canine teeth are adapted for grasping and tearing food, and they play an important role in feeding on prey and in processing tough or fibrous foods.
