We see a great frequency of dental caries in teenagers due to the availability of soft drinks and sports drinks in school. Sports drinks are good to use following athletics to replenish fluids, but regular and indiscriminate use bathes the teeth in sugar and acid and leads to decay. We recommend a switch to flavored waters or plain water to give the teeth a break from the sugar-producing acid and provide a chance for them to re-mineralize and heal (see the section on What is Dental Caries for more information on re-mineralization.)
