Adult Chimpanzees have 32 teeth, as do humans and the other apes. Without the guidance of anterior incisors and canines, this envelope of function can be destructive to the remaining teeth resulting in periodontal trauma from occlusion seen as wear, fracture or tooth loosening and loss.

Human teeth and jaws are markedly smaller for their size than those of other apes, which may be an adaptation to not only having supplanted with extensive tool use the role of jaws in hunting and fighting, but also eating cooked food since the end of the Pleistocene . In platyrrhine species, there are 3 premolars and 2 or 3 molars. These differences can not only be associated with different populations across space, but also change over time so that the study of the characteristics of teeth could say which population one is dealing with, and at what point in that population's history they are.
