Fact Checked

Sports drinks have been designed to help professional athletes recover from the stresses their intense athletic activities put them under.

If you play weekend or social sports, the best drink for you to stay hydrated is water. For this level of activity, sports drinks will provide you with little benefit. However, they will expose your teeth to added sugars and acid that can cause tooth decay and tooth erosion when drunk regularly. They can be particularly damaging to the teeth if you drink them when you are dehydrated.

Ingredients

One quick way to work out whether what you are drinking is beneficial to your dental and overall health is to be familiar with the nutritional label located on the side of the drink.
 
Sports drinks often contain added sugar and ingredients that cause the drink to have a low pH, making it acidic. Drinking these types of drinks regularly can cause damage to the teeth over time. Sugary drinks can cause tooth decay while acidic drinks can cause tooth erosion where the tooth structure is worn away.
 
In the list of ingredients, words such as sugar, glucose, dextrose, fruit juice concentrate and cane sugar may be found. These are all sources of added sugar.
 
Ingredients that can make the drink acidic include citric acid, sodium benzoate, and sodium citrate.

Choose water

When playing sports or exercising, try to remember to take a reusable water bottle that you can refill with tap water (if accessible). Tap water is the best drink choice for healthy teeth and for keeping your body hydrated. In most Australian communities, tap water includes fluoride which helps to protect and strengthen the teeth. 
 
If you regularly drink sports drinks, be sure to drink water after. Also attend for regular dental examinations to ensure your teeth remain healthy.
