Cusp (dentistry)

Cusp (dentistry)
The teeth of the right side of the mouth, shown contacting the teeth in the opposing jaw with their cusp tips.

A cusp is an occlusal or incisal eminence on a tooth.

Canine teeth, otherwise known as cuspids, each possess a single cusp, while premolars, otherwise known as bicuspids, possess two each. Molars normally possess either four or five cusps. In certain populations the maxillary molars, especially first molars, will possess a fifth cusp situated on the mesiolingual cusp known as the Cusp of Carabelli.
