Is Exercise Bad for Your Teeth?

Vigorous exercise is good for almost all of the body — except perhaps the teeth, according to a surprising new study of athletes. The study, published in The Scandinavian Journal of Medicine & Science in Sports, found that heavy training may contribute to dental problems in unexpected ways.
Compared with the control group, the athletes showed significantly greater erosion of their tooth enamel. They also tended to have more cavities, with the risk increasing as an athlete’s training time grew. Over all, the more hours that an athlete spent working out, the more likely he or she was to have cavities.
The researchers found no correlation, however, between consuming sports drinks or any other elements of the athletes’ diets and their oral health.
The extent of the changes in the athletes’ saliva during a workout were something of a surprise, said Dr. Cornelia Frese, a senior dentist at University Hospital Heidelberg, who led the study.
