After exercising, you may reach for a sports drink. Just don't sip too long.

Sports Drinks Can Be Tough on Teeth

While all sweetened drinks are bad for teeth, some energy and sports drinks may be worse, according to one study in General Dentistry. Researchers found that these drinks -- as well as bottled lemonade -- may erode tooth enamel after long-term use. The result is thin, translucent, discolored teeth. To prevent tooth erosion:

• Don't sit and sip these drinks for a long time
• Rinse your mouth with water when finished drinking.
