According to AGD spokesperson Cynthia Sherwood, DDS, soda's combination of sugar and acidity can be damaging to teeth. Though the level of risk varies from person to person, Dr. Sherwood says, "Repeated exposure of soda through sipping over a long period of time increases the risk of getting a cavity."

Dr. Sherwood adds that drinking soda through a straw may help reduce the amount of soda that comes into direct contact with the teeth. She also recommends that soda drinkers rinse their mouths out with water after drinking and use toothpaste that contains fluoride. 

Fact:  

• A typical 12-once can of regular soda contains approximately 10 teaspoons of sugar.
