Premolars (bicuspids) and molars have a series of elevations (points or 'cusps') that are used for breaking up particles of food. Each premolar generally has two cusps, hence the name bicuspid. They are used for holding and crushing food. Molars are the flat teeth at the rear of the mouth.

What tooth numbers are bicuspids?

The bicuspids are #4, 5, 12, 13 (upper jaw) and #20, 21, 28, 29 (lower jaw). Bicuspids are a sort of "in-between tooth," with the properties of both the canine and molar teeth. These teeth transfer food from the canines to the molars for proper grinding.

What type of teeth are also known as bicuspids?

Bicuspids, also known as premolars, are the teeth located between your canines (the pointy teeth located after your top and bottom front 4 teeth) and molars (back teeth). They are often referred to as transitional teeth, taking on properties of both the canines and the molars.
