Your body is a complex machine. The foods you choose and how often you eat them can affect your overall health and the health of your teeth and gums.
Avoid sugar. If you consume too many sugar-filled foods and drinks, you could be at risk for tooth decay. Tooth decay occurs when sugar interacts with plaque to produce acid that attacks teeth, breaking down enamel so that cavities can form.
Tooth decay is the most common chronic childhood disease, but the good news is that it is completely preventable. Foods and drinks that contain sugars of any kind can contribute to tooth decay. Common sources of sugar in the diet include: Soft drinks, Juices, Candy, Cookies and cakes, Breakfast cereals, Yogurt, Flavored milk.
