What do the bicuspids do?

Answer 1

The bicuspid teeth are the ones that are generally just behind the really sharp, vampire-looking teeth called the "canines". The bicuspids are the best teeth in the body for breaking hard objects like nuts. While the sharp incisors are used to cut food, and the canines are for tearing meats, and the molars are build for grinding and most chewing, the bicuspids are sort of in the middle of the road.

Answer 2

They are the teeth that lie between the canines and the molars, sometimes also known as PRE-MOLARS.
