A recent study found a correlation between exercise and teeth loss. While the study was relatively small, involving only 70 people, the researchers found that those who exercised more had a higher risk of rotting teeth. Specifically, the risk of decay correlated with the amount of timing spent training.
The study was based on examining the oral health of those 70 individuals, some of whom were triathletes and others whom were described an non-athletes.
Possible causes for the higher risk of poor oral health among the athletes included: 1) higher levels of alkalinity caused by lower levels of saliva produced while exercising, and 2) the consumption of high-sugar energy and sport drinks.
More alkaline saliva may allow bacteria and plaque to increase, and may have been the issue in this case. No direct link to the sport drinks and nutrition could be found.
At this time, the lead researcher said that the only conclusion that can be drawn from the study is that prolonged endurance training might be a risk factor for oral health.
The study was published in the Scandinavian Journal of Medicine & Science in Sports.
