"teeth" news and stories

A new study from researchers at the University of Iowa School of Dentistry found that Gatorade eroded tooth enamel faster than Coca Cola, Diet Coke, Red Bull or apple juice. Researchers took extracted teeth and coated all but a few spots of each with nail polish. The teeth were then soaked in the sugary drinks for 25 hours, with the liquid being changed every five hours. In the end, Gatorade was the most corrosive on the spots without nail polish. A dental expert cited in a recent WebMD article says that so far, no data shows that sports drinks are actually any worse than sodas on teeth. He added that sipping sodas or other sugary drinks all day is far worse than having one with a meal, as the other foods in the mouth buffer the effects of the drinks. Another expert, quoted in a Forbes article, says that the acidity of these beverages is also to blame. Others critiqued the study, saying that a 25-hour period of exposure to sugary drinks had little to do with real-world situations.
