Incisors
At the front of the mouth are eight thin, straight teeth called incisors – four at the top and four at the bottom – which bite into the food you eat and help you pronounce words as you you speak. Incisors also support the lips.
Canines
On each side of the upper and lower incisors is a single canine tooth, making four in total. Dentists call these slightly pointed teeth cuspids, and like incisors, they cut or shear food and support the lips. Another function of the canines is to help guide all the teeth into place when the upper and lower jaw come together.
Premolars
Behind the canines are the premolars, or, as dentists call them, the bicuspids. Premolars have a flattened top, and are used to chew food and maintain the height of the face. There are eight premolars in an adult's mouth: four on the top and four on the bottom.
Molars
The molars or molar teeth are large, flat teeth at the back of the mouth. They are more developed in mammals. They are used primarily to grind food during chewing.
Most adults have 32 teeth, called permanent or secondary teeth:
8 incisors.
4 canines, also called cuspids.
8 premolars, also called bicuspids.
12 molars, including 4 wisdom teeth
