The premolars are the teeth which are located after the canines and before the molars. In total, there are eight premolars in the mouth of a person, two on the right side maxilla, and two on the left side maxilla, two on the right side mandible and two on the left side mandible. These premolars are called:

  • Maxillary first premolar
  • Maxillary second premolar
  • Mandibular first premolar
  • Mandibular second premolar

Functionally, these are transitional teeth and the food which is eaten is moved from the canines to the premolars first, and then it is moved to the molars so that the food gets ground perfectly. The first mandibular premolar consists of one large buccal cusp and the second mandibular premolar has two lingual cusps.

The first permanent premolar tooth erupts at the age of nine years usually and the second at age ten.
