1. Do sugars cause tooth decay?

Tooth decay is the result of many factors. Heredity, the make-up and flow of saliva, sugars and other carbohydrates such as starchy foods play a part. Bacteria on the teeth (dental plaque) feed on carbohydrates and make acids. The acids then break down the tooth to form a cavity. Frequent eating of snacks that contain carbohydrates, especially those that stick to the teeth, increase chances of decay. "Baby bottle mouth syndrome" is a significant cause of tooth decay in young children. Infants should not sleep with bottles filled with milk, formula or fruit juice, which have carbohydrates.
