Kinds of Teeth

There are different kinds of teeth. Let’s open our mouth and look into the mirror and compare the teeth in front and at the back. We find different types of teeth in our mouth. The teeth are of different shapes because they have different uses.

There are four different kinds of teeth.

They are the following:

Incisors: The teeth in front are for cutting. Those teeth are known as incisors. In all there are 8 incisors.

Canines: The teeth next to the incisors are sharp and pointed. 

They are used for tearing food. For example, used for tearing meat. Those teeth are known as canines. In all there are 4 canines.

Premolars and molars: The teeth at the back of our mouth are flat and wide. Those teeth are known as premolars and molars. These teeth are used to crush and grind the food. There are 8 premolars and 12 molars.

We know an adult person has 32 teeth. There are 16 teeth in the lower jaw and 16 in the upper jaw.

Kinds of Teeth

Let us observe how we use our different kinds of teeth while we eat different food.

(i) When we bite into an apple then we use our incisors. Because we know incisors are our front teeth which we use for cutting the apple. Now after cutting the apple then we chew the apple. To chew the apple we use our premolars and molars. Because we know premolars and molars are used to crush and grind the apple.

(ii) When we tear the meat then we use our canines. Because we know canines are sharp and pointed which we use for tearing the meat. Now after tearing the meat then we chew the meat. To chew the meat we use our premolars and molars. Because we know premolars and molars are used to crush and grind the meat.
