Dens premolaris primus superioris

The premolars, also called premolar teeth, or bicuspids, are transitional teeth located between the canine and molar teeth.

In humans, there are two premolars per quadrant in the permanent set of teeth, making eight premolars total in the mouth.

They have at least two cusps.

Premolars can be considered transitional teeth during chewing, or mastication.

They have properties of both the canines, that lay anterior and molars that lay posterior, and so food can be transferred from the canines to the premolars and finally to the molars for grinding, instead of directly from the canines to the molars.
