Our teeth do the job of breaking, crushing, and mashing our food and are all forms of mechanical digestion. The process of digestion is helped along because there are chemicals in our saliva called enzymes. Enzymes change the rate of a chemical reaction. When a chemical reaction happens in the digestive system, the process is called chemical digestion.

Human beings have four different types of teeth which are used to physically break our food down into smaller pieces so that we can core easily swallow it. Canine and incisors rip and tear our food and premolars and molars crush and mash it further so that we can then safely swallow it.
