The cuspid tooth is perhaps the most recognizable tooth in the mouth because of its pointed shape and length. Located between the incisors and first premolar, cuspids are primarily used for griping and tearing food. Since the cuspid is the longest tooth with one firmly implanted root, it helps guide the teeth and jaws into their proper biting position.

Human adults will develop four cuspids, one in each dental quadrant, sometime between ages 11 or 12. Next to the wisdom teeth, cuspids may become impacted in the bone. Oral surgery along with orthodontic treatment is recommended for patients with impacted cuspids
