when your teeth grind food is it chemical or mechanical
Mechanical and chemical digestion. In mechanical digestion the teeth breakdown food into smaller pieces and in chemical digestion the salivary glands breaks down the food molecules.
The teeth grinding is a mechanical change. The saliva mixing in with the food and starting the digestive process would be a chemical change.
Teeth are extremely important in mechanical digestion of food. It is very difficult to digest the large pieces of food. Only properly masticated food is easily digested. You do not have other organs, which can grind food like your teeth do. Nature has made teeth very hard for this function.
Teeth
Mastication (when teeth cut and grind food) is a physical change.

all grind food
Teeth are involved in mechanical digestion. They physically break down food by crushing, grinding, and cutting it into smaller pieces, making it easier for enzymes in the digestive system to access and break down nutrients.
Chemical digestion uses enzymes and other chemicals to break the bonds in food. Mechanical digestion is basically the teeth grinding the food into physically smaller pieces.
You chew it with your teeth.
they cut in to food like meat but the molars grind and crush food
Teeth crushing food is a physical process because it involves the mechanical breaking down of food into smaller pieces. Chemical processing, on the other hand, involves the breakdown of food molecules through reactions with enzymes and other substances in the body.
