I’ll fess up. Soccer doesn’t really cause cavities…
However, many kids who participate in athletics drink sports drinks (e.g., Gatorade or Powerade). They advertise that they help you to refuel and to restore lost electrolytes, but they don’t tell you that these sports drinks can be just as acidic as soda.
To illustrate this more clearly, see the chart below. It shows the pH (i.e. acidity) of common drinks. The lower the pH, the more acidic the beverage is. In other words, a lower number means it has more potential to harm your child’s teeth.
Approximate pH Range[4, 5]
Water, which is neutral and one of the most beneficial drinks for teeth, has a pH of 7. Compare that to the acidity of soda, a beverage commonly known to be bad for teeth. The pH of soda ranges from 2.7-3.5 and the pH of sports drinks ranges from 2.3-4.4. Not much of a difference between the acidity of soda or sports drinks, right?… Now that you’re informed, it shouldn’t be much of a surprise to learn that many studies now show that sports drinks can lead to enamel weakening and more cavities .
While sports drinks are a popular means for replacing fluids lost during athletic competition, studies have not conclusively shown that these beverages are better than water for hydrating or for maintaining electrolyte balance [1,3]. In fact, cold water remains the ideal replacement beverage for most young athletes .
In addition to cavities, there are some concerns that frequent consumption of sports drinks can also lead to obesity as many of these drinks contain added sugars. So, avoiding these drinks can help improve our overall health as well!
I don’t think you need to ban sports drinks entirely but your child should avoid it during times of sedentary or limited activity. Just be judicious with your child’s consumption of sports drinks and try to limit its use to specific cases such as prolonged vigorous exercise or instances of excessive heat and humidity .
