You may think you’re saving some calories and your health by drinking sparkling water like LaCroix and Perrier, but dentists have said that the flavored drink could make your teeth prone to cavities.

According to Delish, the flavor and bubbles make drinks acidic which can deteriorate tooth enamel. However, sparkling sodas aren’t as acidic as sodas. As long as you only drink them in moderation, you should be fine.

American Dental Association Spokesperson Dr. Edmond R. Hewlett explained that drinking a lot of flavored, sparkling water could erode tooth enamel, which can lead to cavities. There haven’t been many studies conducted regarding flavored waters but sparkling drinks are just as acidic as sodas, and it’s the added flavors that make drinks acidic. When tooth enamel wears down, it can make your teeth sensitive to temperatures and prone to cavities.

The Today Show reported that even unflavored carbonated water is acidic since our mouths turn the bubbles into carbonic acid. Adding a lemon or lime to sparkling water makes the drink much more acidic. Dr. Hewlett advised to reduce the amount of time your teeth touch flavored water, so really, its safer to chug sparkling water than sip it throughout the day. It’s also best to drink sparkling water with meals. Other tips included: “Don’t hold the water in your mouth before you swallow,” and make sure you are drinking regular unflavored water to remain hydrated.

“For an average, healthy person, carbonated, sugar-free beverages are not going to be a main cavity-causing factor,” Delaware dentist Andrew Swiatowicz told The Atlantic, “If you are at all concerned, you can always dilute the carbonated water with regular water, or even just swish with regular water after.”

Now if you were to use alkaline water how would that factor?
