What are the different types of teeth in the oral cavity?

There are four types of teeth in the oral cavity: incisors, canines (also called cuspids), premolars (also called bicuspids) and molars. Most adults have 32 teeth, which are also called secondary or permanent teeth, while in children, there are 3 types of teeth, namely incisors, canines and molars. The teeth in children are called primary or milk teeth. 

What is the function of each type of tooth?

Incissors:

Incisors are the chiselled-shaped eight teeth located in the front of your upper and lower jaw. These are further divided into central incisors and lateral incisors. These teeth help you bite into food because of the sharp edges. 

Canines:

Next to the incisors come the following type, i.e., canines. There are two canines present in the upper jaw and two canines present in the lower jaw. Canines are the pointed teeth in the buccal cavity. They are situated at the ‘corners’ of the dental arches and have a sharp and pointed, and elongated surface that helps in tearing the food.

Premolars:

Next to the canines sits the premolars, which are eight in number. They have a flat surface with ridges that help in grinding and crushing the food into smaller pieces that helps in swallowing. 

Molars:

The last set of teeth is the molars, which are the biggest and strongest teeth. These teeth help in grinding food because of their large surface area. The molars include the wisdom teeth, which are the last teeth to erupt; usually, they come in between the ages of 17 to 25 and are four in number. These are also called third molars. However, sometimes these are stuck under the gums, either entirely or partially. These are called impacted teeth and, in most cases, are extracted.
