उत्तर
molars and premolars
Explanation:
Our teeth cut, tear and grind the food before we swallow it. There are four types of teeth in our mouth –
- Incisors: These are the front eight teeth, four in the upper and four in the lower jaw. These are well adapted for cutting and biting of food items.
- Canines: There are four canines, one canine each on either side of each jaw. These teeth are well adapted to hold and tear the food.
- Premolars: There are eight premolars in total, two premolars in each half of the both upper and lower jaws. These are well adapted to crush and grind food.
- Molars: There are twelve molars, three in each half of the both upper and lower jaws. These are well adapted to crush and grind the food.
