Sports drinks may help you re-fuel after a workout, but new information suggests they could also be harming your teeth.
A study found sports drinks can damage tooth enamel which could increase the risk for tooth decay. Researchers found the sports drinks damaged enamel three to 11 times more than cola based drinks. They say rinsing your mouth with water after consuming sports drinks can help protect the teeth.
The enamel was removed from intact human teeth, weighed and tested in lab environment. Saliva can help neutralize the effect 30 to 60 minutes after exposure. Sipping over long periods of time accelerates the process. Nitric acids take longer to neutralize than phosphoric acids found in colas.
