A recent study at the Department of Cariology & Comprehensive Care at New York University College of Dentistry studied the effect of several top selling sport drinks on teeth. What they discovered was that the tooth surface “softened” after being exposed to the sport drinks. Many sport drinks not only contain sugar, but equally damaging is the level of citric acid they may contain and the subsequent erosion of the tooth enamel. Although this is not decay, the softened tooth surface can lead to erosion possibly leading to exposure to the sensitive inner dentin or root surface of the teeth. This could eventually lead to an increase in future decay and sensitivity. Research Dr. Wolf also stated “To prevent tooth erosion, consume sports drinks in moderation, and wait at least 30 minutes before brushing your teeth, to allow softened enamel to re-harden." Limiting the number of sport drinks and rinsing with water afterwards is also prudent.
