Saliva breaking down a piece of bread is a chemical change because enzymes in the saliva break down the starches in the bread into simpler sugars through a chemical reaction. This results in a change in the composition and structure of the bread at a molecular level.

When you put food in your mouth, two processes are at work to begin digesting.The first process is chewing. This causes a physicalchange in the food. In short, it changes shape and mixes with saliva.The second process is digestion by saliva. Saliva induces some chemical changes, such as the break down of starches into sugars.
Digestion involves both physical and chemical changes. The teeth crush food into smaller particles, which is a physical change, whereas the saliva, stomach, gall bladder, and pancreas contain chemicals that break down food chemically in the mouth, stomach, and small intestines.
