Molar

One of four types of tooth found in heterodont mammals. Molars are low, flat teeth, usually in the rear of the mouth, that are used for crushing and grinding if low-cusped and for puncturing if high-cusped. There are normally three molars per quadrant in the human jaw.

Cf. incisor, canine, and premolar.
