Detailed explanation-1: -The term heterodonty indicates that there are tooth shape differences along the tooth row-incisors and canines rostrally and cheek teeth (premolars and molars) caudally. These are the four tooth classes of mammals: incisors, canines, and premolars are replaced, they are deciduous teeth; molars are not replaced.

Detailed explanation-2: -Humans have two sets of teeth: primary (or baby) teeth and permanent (adult) teeth, which develop in stages.

Detailed explanation-3: -An adult human has 32 permanent teeth which are of four different types, namely incisors, canine, premolars and molar. Such type of dentition is called heterodont dentition.

Detailed explanation-4: -Whether the teeth are the same or different in shape. Homodont-Teeth are all about the same shape (most vertebrates, few mammals). Heterodont-Teeth have different form and functions in different parts of the tooth row (mammals, a few fish).

Detailed explanation-5: -The permanent teeth in humans are of different shapes and sizes and perform various infections. These type of teeth is called heterodont.
