Tooth enamel, to play on a phrase from Shakespeare, is made of “sterner stuff.” The strongest substance in the body, enamel can take years of biting and chewing and keep on going.
It does have one nemesis, though—mouth acid, which can soften and erode enamel’s mineral content. This is less of a concern if you have healthy saliva flow, because saliva neutralizes acid in thirty minutes to an hour after an acid attack and can also help re-mineralize the enamel. Daily brushing and flossing also help curb mouth acid by reducing the bacteria that produces it.
But as effective as saliva is at neutralizing mouth acidity, it can be overwhelmed by outside acid derived through certain foods and beverages. In the past couple of decades, at least two of these acid sources have grown in prominence: energy drinks and, believe it or not, sports drinks.
Just how acidic are they? The pH scale runs from 1 to 14, with acidity on the low end and alkalinity on the higher (7 is neutral). Tooth enamel begins dissolving below 5.5. Laboratory tests have pegged the average pH of energy drinks at 3.05 and sports drinks, 2.91.
Because of their acidity, frequent energy or sports drink consumption will bring mouth pH into the danger zone for tooth enamel. It’s even more likely if these beverages are sipped over an extended period, which can prevent saliva from getting ahead of any newly introduced acid.
Keeping your distance from these beverages is probably the safest bet. But if you do imbibe occasionally, follow these common sense tips:
- Avoid sipping the beverage over long periods—and try to limit drinking them to meal times;
- After drinking a beverage, wash your mouth out with water and wait an hour to brush to give your saliva time to neutralize any acid.
- Practice consistent, daily brushing and flossing.
Above all, keep a healthy respect for acidic foods and beverages like energy and sports drinks and don’t overuse them. Your tooth enamel will appreciate it.

Although a variety of foods provide energy-producing carbohydrates, sugar is among the most popular. It’s believed we universally crave sugar because of the quick energy boost after eating it, or that it also causes a release in our brains of serotonin endorphins, chemicals which relax us and make us feel good.
But there is a downside to refined sugars like table sugar or high-fructose corn syrup: too much in our diets contributes to conditions like cardiovascular disease, diabetes, and dental disease. On the latter, sugar is a primary food source for oral bacteria; the more sugar available in the mouth the higher the levels of bacteria that lead to tooth decay and gum disease.
Moderating your intake of refined sugars and other carbohydrates can be hard to do, given that many processed foods contain various forms of refined sugar. A diet rich in fresh fruits and vegetables helps control sugar intake as well as contribute to overall health. Many people also turn to a variety of sugar substitutes: one study found roughly 85% of Americans use some form of it in place of sugar. They’re also being added to many processed foods: unless you’re checking ingredients labels, you may be consuming them unknowingly.
Sugar substitutes are generally either artificial, manufactured products like saccharin or aspartame or extractions from natural substances like stevia or sorbitol. The good news concerning your teeth and gums is that all the major sugar substitutes don’t encourage bacterial growth. Still, while they’re generally safe for consumption, each has varying properties and may have side-effects for certain people. For example, people with phenylketonuria, a rare genetic condition, can’t process aspartame properly and should avoid it.
One alcohol-based sweetener in particular is of interest in oral care. A number of studies indicate xylitol may actually inhibit bacterial growth and thus reduce the risk of tooth decay. You can find xylitol in a variety of gum and mint products.
When considering what sugar substitutes to use, be sure you’re up to date on their potential health effects for certain individuals, as well as check the ingredients labels of processed foods for added sweeteners. As your dentist, we’ll also be glad to advise you on strategies to reduce sugar in your diet and promote better dental health.
