Premolars Premolars, or bicuspids, are used for chewing and grinding food. Adults have four premolars on each side of their mouths — two on the upper and two on the lower jaw. There are no primary premolars; the first premolars appear around age 10, with the second premolars arriving about a year later.

Types of Teeth and Their Functions
- Incisors – The four front teeth in both the upper and lower jaws are called incisors.
- Canines – There are four canines in the oral cavity.
- Premolars (Bicuspids) – These teeth are located behind and adjacent to the canines and are designed to crush food.
- Molars – The most posterior teeth in the mouth are the molars.
Also Know, what each tooth is used for? Incisors — the sharp, chisel-shaped front teeth (four upper, four lower) used for cutting food. Canines — sometimes called cuspids, these teeth are shaped like points (cusps) and are used for tearing food. Premolars — these teeth have two pointed cusps on their biting surface and are sometimes referred to as bicuspids.
Moreover, are premolars important?
Why you need your premolars but not your wisdom teeth The premolars are considered transitional teeth, as they work to guide food from the cuspids near the front of the mouth back to the molars near the rear of the mouth for chewing.
What is the difference between molars and premolars?
Premolars and molars play a vital role in the process of grinding and chewing. In this post, we will discuss some differences between molars and premolars: The lower molars usually have 2 roots while the upper molars have 3 roots. They have a flat surface and have 4 cusps to aid easy chewing of the food.
