Answer:

There are four types of teeth in human

1. Incisor: These are long, chisel-like teeth for gnawing the food. They are more developed in gnawing animals. Examples: lagomorphs, rodents, tusk of elephant are modification of upper Incisor. Tusk is used to protect from enemies, attack on enemies (not for feeding purpose)

2. Canines: These are sharp-pointed teeth meant for tearing the food. Canines are most developed in carnivorous animals. canines are absent in herbivorous animals. Example: Rabbits do not have canines. In herbivorous, the space of canine in gums is empty and this empty space is called diastema.

4. Molars (Cheek teeth): These also meant for chewing & crushing of food. They are rectangular in shape. Premolar and molar help in the mastication of food. In human teeth of upper jaw are attached to the maxilla bone. While teeth of lower jaw are attached to the mandible bone.

Human dentition Formula

$\frac{2123}{2123}$

This formula illustrates no of teeth in half upper jaw

2= Incisor

1= canine

2= premolar

3= molar
