Number of Teeth in the Human Mouth. How many teeth are there in the human mouth? 32. Adult humans have 32 permanent teeth in a complete set. Human teeth are made up of 12 molars found in the back of the mouth, 8 premolars or bicuspids found adjacent to the molars, 4 cuspids or canines, and 8 incisors found at the front of the mouth.
A normal adult mouth has 32 teeth, which (except for wisdom teeth) have erupted by about age 13: â¢ Incisors (8 total): The middlemost four teeth on the upper and lower jaws. â¢ Canines (4 total): The pointed teeth just outside the incisors. â¢ Premolars (8 total): Teeth between the canines and molars. â¢ Molars (8 total): Flat teeth in the rear of the mouth, best at grinding food. â¢ Wisdom teeth or third molars (4 total): These teeth erupt at around age 18, but are often surgically removed to prevent displacement of other teeth.
