The saliva contains salivary amylase which is an enzyme that starts the process of digestion of sugars and starch in food. Starch which is contained in large quantities in many staple foods like rice, maize, yam, cassava and potatoes is broken down into glucose.

Particles of food and debris remain on the surface of the teeth. Bacteria in the mouth use these sugars as their energy source and in the process, the produce acids which destroy the hard tissues of the teeth. If the breakdown of the minerals in the teeth is more than the buildup, it results in tooth decay.

Risk factors for tooth decay include irregular and poor cleaning of teeth, eating foods high in sugars and low levels of fluoride.
