Sparkling water

Sparkling water is in, but is it good for your teeth?

What makes carbonated drinks bubbly?

The fizz comes from carbon dioxide, which quickly turns into carbonic acid.

Is carbonation harmful?

The level of acid in most sparkling water does not pose a threat to your teeth, according to the American Dental Association. When researchers soaked teeth in sparkling water versus regular water, they observed no significant difference in enamel erosion. More research is needed to fully explore the topic, but current knowledge suggests the coast is clear. 

But isn't it acidic?

Even though fizzy water is more acidic than still water, its pH is lower than drinks like orange juice.

Try these tips to protect your teeth:

Avoid harmful additives. Some flavors like lemon and orange contain citric acid, while others are sweetened with sugars, which can put you at greater risk for cavities.

Skip the citrus. Adding a slice of lemon or lime increases the acidity of your drink and wears away tooth enamel.

Wash it down quickly. It’s better to drink it all in one sitting or with a meal rather than slowly sipping on it throughout the day.

The verdict: Enjoy sparkling water in moderation, but make plain water your drink of choice. The fluoride added to most tap water gives your enamel a boost that helps protect it from decay.
