The crown of each premolar is compressed anteroposteriorly and surmounted by two cusps, and the neck is oval. The root is single and compressed in all premolars except the upper first, which usually has two roots. Usually an anterior and a posterior groove are also present. The upper premolars are larger than the lower premolars. Also called bicuspid. Compare canine tooth, incisor, molar.
