The premolar teeth or bicuspids are transitional teeth located between the canine and molar teeth. Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome.

Molars are the rearmost and most complicated kind of Tooth in most Mammals In many mammals they grind food hence the Latin name mola, " Millstone In humans, there are two premolars per quadrant, making eight premolars total in the mouth. They have at least two cusps. A cusp is an occlusal or incisal eminence on a tooth Canine teeth otherwise known as cuspids, each possess a single cusp while Premolars Premolars can be considered as a 'transitional tooth' during chewing, or mastication. It has properties of both the anterior canines and posterior molars, 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.

The premolars in humans are the maxillary first premolar, maxillary second premolar, mandibular first premolar, and the mandibular second premolar. The maxillary first premolar is the Tooth located laterally (away from the midline of the Face) from both the Maxillary canines of the Mouth The maxillary second premolar is the Tooth located laterally (away from the midline of the Face) from both the Maxillary first premolars of the The mandibular first premolar is the Tooth located laterally (away from the midline of the Face) from both the Mandibular canines of the Mouth The mandibular second premolar is the Tooth located distally (away from the midline of the Face) from both the Mandibular first premolars of the
There is always one large buccal cusp, especially so in the mandibular first premolar. The lower second premolar almost always presents with two lingual cusps.
Premolar teeth by definition are permanent teeth distal to the canines preceded by deciduous molars.

Mammals ( class Mammalia) are a class of Vertebrate Animals characterized by the presence of Sweat glands, including sweat glands The most mesial two have been lost in New World monkeys, apes, and humans. There are numerous commonly used terms of relationship and comparison that refer to different aspects of teeth and are frequently utilized in articles about Dentistry.
