"Other beverages, such as orange juice and soda, also may cause tooth erosion when consumed in high quantities," says AGD spokesperson Charles Perle, DMD, FAGD. "Bulimia is another cause of tooth erosion because of constant regurgitation of stomach acids."

When drinking acidic beverages, use a straw or take small sips, limiting the acid contact against the teeth. "Remember, your teeth aren't thirsty, your throat is," says Dr. Perle.

The study indicated a low saliva flow increased the erosion potential because saliva serves as an enamel barrier. Brushing before or after wine tasting increases erosion by removing the protective saliva barrier, so brush gently only before bedtime using a toothbrush with soft bristles and fluoride toothpaste.
