There are four different types totaling 32 teeth in the mouth of an adult.
An adult person has 32 teeth.
INCISORS or Cutting teeth:
The 8 incisors are the very front teeth with rather flat surfaces, a straight sharp horizontal edge for cutting and biting the food and one long, single, conical root.
The 4 canine teeth are very strong, pointed corner teeth for tearing and shredding, placed laterally to each lateral incisor. They are larger and stronger than the incisors. The upper canine teeth are sometimes called eyeteeth.
The 8 premolars, used for the chewing of the food, are placed lateral to and behind the canine teeth, with a flat upper surface and 1-2 roots.
Molars or Molar teeth:
The 12 molars are the back teeth. Molars are the largest of the permanent teeth, used for the final chewing and grinding of the food before swallowing. The very back molars are also known as wisdom teeth.
