उत्तर
Human teeth are of four kinds:
- Incisors are the four front teeth at the middle of each jaw. They are chisel-shaped for biting and cutting.
- Canines are one on either side of the incisors in each jaw. They are pointed for tearing the food.
- Premolars are two on each side of canines in each jaw. They help in crushing and grinding the food.
- Molars are the last three teeth on each side in each jaw. They have a broad uneven surface for finer crushing and grinding of ingested food.
