when your teeth grind food is it chemical or mechanical
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.

Salivary Glands performs Chemical Digestion
Mastication (when teeth cut and grind food) is a physical change.

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.
Mechanical digestion chops the food in to smaller pieces, thus exposing more of it to the enzymes of the chemical digestion.Mechanical digestion begins in the mouth by the teeth, tongue and saliva. Mechanical digestion is important for chemical digestion because when food is broken down into smaller particles by mechanical means, chemical digestion will be more efficient.
they cut in to food like meat but the molars grind and crush food
