How does my diet affect the development of cavities?

Tooth decay is a destruction of the tooth enamel. It occurs when foods containing carbohydrates (sugars and starches) such as milk, pop, raisins, cakes or candy are frequently left on the teeth. Bacteria that live in the mouth thrive on these foods, producing acids as a result. Over a period of time, these acids destroy tooth enamel, resulting in tooth decay. Eating nutritious, balanced meals and limiting snacking can help to prevent cavities.

The nutrition needed by bacteria that cause cavities comes from your diet. Foods and drinks that contain sugar or other carbohydrates and adhere to your teeth, such as milk, honey, sugar, soda, candy, dried fruit, cake and cookies, chips, dry cereal, and ice cream have a higher probability of causing cavities than food and drink that is low in sugar and/or which can be easily eliminated from the mouth by saliva. The longer the food or drink stays in the mouth clinging to the teeth, the more likely it can come in contact with plaque bacteria that produce the acid that causes cavities. If you often snack or drink sodas, the acid has more time to attack your teeth. Rinsing your mouth after ingesting a snack or soda eliminates some of the food debris, but brushing your teeth is more beneficial.
