The first premolar, also known as the first bicuspid, is typically the fourth tooth from the midline in each quadrant of the mouth. In adults, it is located between the canine and the second premolar. The first premolar usually has two cusps and is primarily used for grinding food. In the upper jaw, it often has a slightly larger and more prominent structure compared to its lower counterpart.

AnswerUpper molarsStrictly speaking, the only permanent tooth with a regularly occurring transverse ridge is the mandibular first premolar. However, on very rare occasions the maxillary first premolar and maxillary first molar may have a transverse ridge as well. There is still disagreement determining the frequency that the buccal and lingual triangular ridges meet without being interrupted by the central groove.
