Bicuspid or Pre-Molar

Bicuspid or Pre-Molar Edmonton

Premolars, also called bicuspids, are the permanent teeth located between your molars in the back of your mouth and your canine teeth (cuspids) in the front. They are transitional teeth, displaying some of the features of both canines and molars, that help cut and move food from the front teeth to the molars for chewing. There are four premolar teeth in each dental arch - upper and lower.

The main distinctions between premolar and molar teeth are in their size and shape. While a molar has four cusps or points, a premolar has only two. Molars are also significantly larger than their bicuspid neighbors.

Both premolar and molar teeth have pits and fissures between their cusps that can trap the food and bacteria that lead to cavities, although the crevices in molars are deeper and more difficult to keep free of cavity-causing particles.

The premolar teeth, with the exception of the upper or maxillary first bicuspid, usually have a single root. The maxillary first premolar usually has two roots, though a single root is also possible. Molars, in contrast, all have at least two roots, with the upper molars typically having three.
