Maxillary first premolars and mandibular molars usually have two roots. There are four classes of teeth&colon; incisors, canines, premolars, and molars. Of these teeth, there are four incisors, two canines, four premolars, and six molars. Instead, the teeth that precede the permanent premolars are the deciduous molars. Several hominin remains, including premolars, molars, and incisors, were identified. The canines are usually replaced first, followed by the premolars, incisors, and then molars. The holotype, CCH6, comprises the upper right premolars and molars. All horses have 12 premolars, 12 molars, and 12 incisors. Maxillary premolars and the mandibular first premolars usually have two cusps. The lower premolars and the upper second premolar usually have one root. The number of premolars, incisors and canines decreased. It had 3 premolars and 3 molars in both jaws. The profiles of the molars are more rounded than those of the premolars. It has two pairs of lower incisors with three pairs of lower premolars. The premolars and molars are at the back of the mouth.
