A recent study published in the May/June issue of General Dentistry, found that an alarming increase in the consumption of sports and energy drinks, especially among adolescents, is causing irreversible damage to teeth-specifically, the high acidity levels in the drinks erode tooth enamel, the glossy outer layer of the tooth. The researchers found that damage to enamel was evident after only five days of exposure to sports or energy drinks, although energy drinks showed a significantly greater potential to damage teeth than sports drinks. In fact , the authors found that energy drinks caused twice as much damage to teeth as sports drinks.
