This document describes the different types of teeth and their functions. It discusses the four types of teeth: incisors, which cut food; canines, which tear and hold food; premolars, which have a grinding function; and molars, which grind and chew food. It also notes that humans have two sets of teeth - milk (primary) teeth when young, which are later replaced by permanent adult teeth starting around age 6 or 7 years old.
