Human teeth are the teeth found in the human mouth. They function in mechanically breaking down items of food by cutting and crushing them in preparation for swallowing and digestion. The roots of teeth are embedded in the upper jaw or the lower jaw and are covered by gums.
Humans usually have 20 primary teeth and 32 permanent (adult) teeth. Teeth are classified as incisors, canines, premolars and molars. Incisors are primarily used for biting pieces from foods such as raw carrots or apples and peeled but uncut bananas, while molars are used primarily for grinding foods after they are already in bite size pieces inside the mouth.
