Types of Teeth and their functions

As we discussed, an adult humans have 32 permanent teeth and children have 20 milk teeth or deciduous teeth at the age of 3 years.

Let’s further see the numbers of each and every type of tooth and their functions in detail.

1. Incisors teeth :

These are your front teeth or anterior teeth. Every individual has a total of 8 incisors and has two types of incisor teeth, 2 central incisors and 2 lateral incisors on each side in the upper and lower jaw.

Incisors are flat and have sharp edges (chisel shaped) to bite into the food and cut it in smaller pieces.

2. Canines teeth :

There are 4 canines in total, 1-1 canine on each side in the upper and lower jaw. They are sharp pointed teeth and mostly used for tearing down food items.

3. Premolar teeth :

Premolars are 8 in total, 2-2 premolars on each side in the upper and lower jaw. They are mainly used for cutting and grinding the food items. Premolars are absent in children.

4. Molar teeth :

Molar teeth are 12 in total in adults and 8 in numbers in children. Children have 2-2 molars on each side in the upper and lower jaw and adults have 3-3 molars (including Wisdom teeth, last 3rd molar tooth) on each side in upper and lower jaw.

3rd Molars or Wisdom teeth are absent in children.

Wisdom teeth or 3rd molars are the last teeth in the mouth, mostly they are not functional and not used for chewing food. Not all people may have wisdom teeth as sometimes it’s covered by gums or gingival tissue and not erupted in the oral cavity (mouth) also known as impacted wisdom teeth. This causes pain on movement of teeth.

To know the position of wisdom teeth, radiographic examination is required. Many times, wrongly positioned wisdom teeth damage the tooth close to it, and in some cases it causes pain; in those cases removal of wisdom teeth is advised. Because these teeth are none functional, it won’t affect your normal chewing of food.

Molars are the largest teeth and have large surface area to help them to chew and grind food to make it smaller and facilitate swallowing it.
