Which teeth are used for chewing and grinding

The teeth used for chewing and grinding are called the molars and premolars. These are the larger teeth in the back of the mouth that are used for grinding and crushing food.

There are a total of eight molars and eight premolars in the mouth, with four on the top and four on the bottom.

The molars and premolars have a flat, wide surface that is covered in tiny ridges and grooves. These ridges and grooves help the teeth grip and grind food into smaller pieces that are easier to swallow and digest.
