The four types of teeth in our mouth are:
1) Incisors- They help us in biting and cutting the food.
2) Canines- They help us in piercing and tearing the pieces of meat.
3) Premolars- They assist the molars by holding the food with their cusps and also crushing them.
4) Molars- They help us in chewing and grinding the food so that it can be swallowed easily.
