Sports drinks can cause tooth erosionApril 4th, 2009 - 3:29 pm ICT by IANS
Washington, April 4 (IANS) Sipping sports drinks may boost your energy levels but they have a flip side - they may erode your teeth.
In a study, researchers found that their prolonged consumption may be linked to erosive tooth wear, in which acids eat away the tooth’s smooth hard enamel coating and trickle into the bonelike material underneath, causing tooth to soften and weaken.
The condition affects one in 15 Americans and can result in severe tooth damage and even tooth loss if left untreated.
“This is the first time that the citric acid in sports drinks has been linked to erosive tooth wear,” said Mark Wolff, professor of cariology and comprehensive care at New York University College of Dentistry, who led the study.
Wolff’s research team cut in half cow teeth, which were used for the study because of their close resemblance to human teeth. They immersed one half of the specimens in a sports drink, the other half in water, then compared the two halves and discovered that the one exposed to the sports drink displayed a significant amount of erosion and softening.
“Five teeth were immersed in each drink for 75 to 90 minutes to simulate the effects of sipping on sports drinks over the course of the day,” Wolff said. The researchers evaluated the effects of a range of top-selling sports drinks on the cow teeth.
According to Wolff, brushing teeth immediately after consuming a sports drink can compound the problem of tooth erosion, because softened enamel is very susceptible to the abrasive properties of toothpaste.
“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,” Wolff advised.
“If you frequently consume sports drinks, ask your dentist if you should use an acid-neutralising remineralising toothpaste to help re-harden soft enamel,” he said.
The findings were presented at the annual meeting of the International Association for Dental Research in Miami, said a New York University release.
