The different types of teeth are distinguished on the basis of morphology, position, and function (Fig. 8.278A).
In adults, there are 32 teeth, 16 in the upper jaw and 16 in the lower jaw. On each side in both maxillary and mandibular arches are two incisor, one canine, two premolar, and three molar teeth.
The incisor teeth are the “front teeth” and have one root and a chisel-shaped crown, which “cuts.”
