Myth - More sugar means more tooth decay

Fact: It isn't the amount of sugar you eat; it is the amount of time that the sugar has contact with the teeth. Foods such as slowly-dissolving candies and soda are in the mouth for longer periods of time. This increases the amount of time teeth are exposed to the acids formed by oral bacteria from the sugars. Some research shows that teens obtain about 40 percent of their carbohydrate intake from soft drinks. This constant beverage use increases the risk of tooth decay. Sugar-free carbonated drinks and acidic beverages, such as lemonade, are often considered safer for teeth than sugared beverages but can also contribute to demineralization of tooth enamel if consumed regularly.
