PREMOLARS

The premolars are located between the canines and the molars. The crown of each premolar features two cusps which facilitate the grinding and chewing of food. The premolars are not represented in deciduous teeth, but are permanent teeth which erupt once the child approaches nine or ten years of age. The premolar roots feature single root stems which anchor them in the maxilla and mandible, similar to the incisors and canines.
