Athletes are damaging their teeth with energy drinks, study finds


British Olympic and professional athletes regular use of sports drinks, energy bars and gels could be damaging their teeth, according to a study.

Researchers from University College London surveyed 352 female and male athletes across 11 sports, including cycling, swimming, rugby, football, rowing, hockey, sailing and athletics. The study concluded that elite athletes have poor oral health despite their efforts to care for their teeth.

The findings, published in the British Dental Journal, showed 94% of athletes brushed their teeth twice a day, compared with 75% of the general public, while 44% flossed regularly, compared with 21% of the public.

The study builds on previous research by the UCL Eastman Dental Institute that measured tooth decay, gum health and acid erosion in elite athletes, which showed that 49.1% of athletes had untreated tooth decay. And 32% reported that their oral health had a negative impact on their training and performance. The latest study attempted to explore why.

Researchers found that 87% of athletes regularly drink sports drinks, 59% eat energy bars and 70% use energy gels (70%), all of which are known to damage teeth.

Previous findings have suggested that elite athletes may have a higher risk of oral disease from a dry mouth during intensive training.

UCL’s Dr Julie Gallagher said: “We found that a majority of the athletes in our survey already have good oral health related habits in as much as they brush their teeth twice a day, visit the dentist regularly, don’t smoke and have a healthy general diet.

“However, they use sports drinks, energy gels and bars frequently during training and competition; the sugar in these products increases the risk of tooth decay and the acidity of them increases the risk of erosion. This could be contributing to the high levels of tooth decay and acid erosion we saw during the dental check-ups.”

Gallagher added that the athletes who were interviewed for the study were willing to consider behaviour changes such as additional fluoride use from mouthwash, more frequent dental visits and reducing their intake of sports drinks to improve oral health.

Researchers went on to work with the elite athletes and their support team members to design an oral health intervention study. The results will be published soon.
