The maxillary second premolar is one of two teeth located in the upper jaw laterally (away from the midline of the face) from both the maxillary first premolars of the mouth but mesial (toward the midline of the face) from both maxillary first molars. The function of this premolar is similar to that of first molars in regard to grinding being the principal action during mastication commonly known as chewing.
