There are various types of dentitions based on tooth attachment, type of teeth in the jawbone, type of molar and premolars - which are types of teeth, and so on. Lophodont is one of the types of molars and premolars.

In many cases, food that is hard and abrasive is consumed by herbivores. They must grind their food efficiently. Their grinding action is improved by the addition of hard enamel ridges to the teeth. These teeth are often either lophodont or selenodont. These have elongated ridges which are called loops that run between cusps. The molars and premolars of tapir, manatees, and many rodents are lophodont.
