Is Sparkling Water Bad for My Teeth?

We have all heard that soda is bad for our teeth due to the high sugar content, but what about carbonated water, is sparkling water bad for my teeth? The short answer is no, but plain water is always the best option as it contains fluoride (double check your tap water to ensure it contains fluoride) and naturally helps fight cavities by washing away leftover food which if left on the teeth and gums can lead to bacteria/plaque build up, and keeps your mouth from becoming dry which can lead to bad breath and an increased risk of cavities.

Sparkling water may have a higher acidity level, but studies have shown that tap water and carbonated water have the same effect on teeth. To our teeth, water is water, no matter if it is bubbly or comes right from the faucet. However, it is important to know what is in those carbonated drinks.

Things to look for:


Check the nutrition label for the amount of sugar in the drink. Ideally, this number should be 0 grams and if it is not you should likely look for another sparkling water option. Also, be sure to check the ingredients. Look on your label for any added sugar. Tip: Generally, any ingredients that end in “ose” are sugar! Examples; sucrose, dextrose, fructose, maltose, etc.


If your sparkling water is citrus flavored it likely has elevated acidity levels and can increase your risk of damaging the enamel of your teeth. Therefore, aim to avoid citrus (lemon, lime, orange, etc.) flavored carbonated water.

Go Ahead Reach for That Sparkling Water

When in doubt, fluoridated tap water is always the best option for our teeth, but if sparkling water helps to decrease the number of sodas or sugary drinks you drink, then go ahead and reach for that fizzy sugar-free water!
