Bicuspid mean teeth having two cusps. They are also known as pre molars, so called because they are situated in front of molars.

The bicuspids are teeth that are situated just behind the long canines and in front of the big molars.

The bicuspids help in breaking hard objects like nut, while incisors are for cutting teeth, canines help in tearing food and molars in grinding purpose.

Bicuspid teeth appear between anterior and posterior teeth, they have the properties of both anterior teeth and posterior teeth, to help them in transferring the food from anterior teeth to posterior teeth.

Hence they help in transferring the food from anterior teeth to posterior teeth for grinding purpose.

Primary molars shed by the age of ten or eleven years and are preceded by pre molars at the age of ten or twelve years.

Bicuspid teeth are shorter than canines and smaller than molars.

They appear in pairs in all the four quadrants of the mouth. This is the normal exfoliation and eruption process.

Bicuspid teeth are maxillary first premolar, maxillary second premolar and mandibular first The Bicuspids premolar and mandibular second premolar.

There are usually two cusps in the bicuspids, bigger buccal and smaller lingual; hence the name bicuspid, the mandibular bicuspid has two small lingual cusps.

The maxillary and mandibular first premolar is usually extracted during orthodontic treatment to create the desired space for any patient having proclination of crowed teeth.

These Bicuspid teeth have a single root in all except maxillary first premolar having two roots.

The roots are usually straight; sometimes they have a buccal or palatal curve.
