Bicuspid
Bicuspid
Bicuspid (/baɪˈkʌspɪd/), also known as a premolar tooth, is one of the types of teeth in the human mouth. The term "bicuspid" is derived from the Latin words "bis" meaning "two" and "cuspis" meaning "point" or "peak". This refers to the two pointed cusps found on the biting surface of the tooth.
Anatomy
The human bicuspid is located between the canines and molars. There are two bicuspids per quadrant in the permanent dentition, making a total of eight bicuspids in the mouth. They are used for chewing and grinding food.
Types
There are two types of bicuspids in the human mouth: the first bicuspid and the second bicuspid. The first bicuspid, also known as the first premolar, is closer to the front of the mouth. The second bicuspid, also known as the second premolar, is closer to the back of the mouth.
