Although energy drinks are but a blip on the historical timeline compared to coffee or tea, they've displaced these traditional stimulants among nearly half of today's adolescents and young adults. But these sweetened “processed” drinks are also controversial among healthcare experts—particularly the effect they may have on dental health.
Besides the added sugar found in many energy drinks—a prime food source for harmful bacteria—many energy drinks and their cousins sports drinks contain significant amounts of acid. High levels of acid soften and erode tooth enamel, which can lead to tooth decay.
During one experimental study, portions of tooth enamel were subjected to a number of name-brand energy and sports beverages. Over the course of a few days, researchers recorded significant enamel loss, especially involving the energy drink samples.
Abstaining from both energy and sports drinks is a sound way to avoid enamel erosion (the best hydrator, it turns out, is simply water). But if you do wish to continue consuming these beverages, here are a few common sense precautions for reduce the risk of harm to your teeth.
Partake only at mealtimes. Among its many abilities, saliva is able to neutralize oral acid and bring the mouth to a neutral pH level within 30 minutes to an hour. But if you're sipping on high-acid beverages throughout the day, your saliva may not be able to compensate effectively. Drinking energy drinks only during a meal helps saliva do its acid-buffering job better.
Rinse with water afterwards. Rinsing with a little water after eating or drinking something acidic can help reduce the pH levels in the mouth. That's because water is by and large neutral on the acidic/alkaline scale. Because it's not adding more, rinsing with water dilutes any concentrations of acid that may still be lingering in your mouth.
Don't brush immediately. Brushing is essential to overall hygiene, but if you do it right after you eat or drink, you could be doing more harm than good. That's because elevated acid levels that naturally occur after consuming foods and beverages can temporarily soften and demineralize the surface enamel. Brushing could remove microscopic bits of softened enamel. If you wait an hour to brush, you'll be giving saliva time to “re-mineralize” your enamel.
