A Safer Soft Drink?
Yearning for a soft drink? Reach for a root beer. Exposing teeth to soft drinks, even briefly, causes dental erosion—and longer exposure can cause enamel loss. But root beer does not contain phosphoric or citric acids that harm teeth, according to a study in General Dentistry, the journal of the Academy of General Dentistry. A lot of people think sugar is the only threat from soft drinks. But even diet drinks contain phosphoric acid, citric acid, or both, which can cause dental erosion. Many of the soft drinks that people consume may contain 9 to 12 teaspoons of sugar and have an acidity that approaches the level of battery acid. Having soft drinks only with meals and using a straw, which reduces soda’s contact with teeth, may help prevent problems.2
