Dentition

Dentition is the development of teeth and where the teeth are in the mouth. Almost all mammals have up to four different types of teeth: incisors, canines, premolars, and molars. Animals that have different types of teeth are called "heterodont". If they do not, they are called "homodont".

In mammals, the young have a set of primary teeth (milk teeth) that fall out after a few years. When they fall out, adult teeth grow in. Animals that have milk teeth and adult teeth are called diphyodont.
