Is La Croix Seltzer Water Harming Your Teeth?

Sorry, everyone, but the La Croix phenomenon is ultimately not dental-health friendly.

"Even when it’s unflavored, fizzy water contains an acid—carbonic acid—that gives it its bubbles. That acidity can gradually wear away tooth enamel.The good news is, it’s a relatively weak acid. Unless they’re flavored with citric or other acids, seltzers tend to have more neutral pH values than soft drinks like Coke. While bottled flat water has a pH of about 7—or totally neutral—that of Perrier is about 5.5.

"The flavorings, though, can bring the pH down, making the beverages even harsher on tooth enamel. One 2007 study in which researchers exposed human teeth to flavored sparkling waters for 30 minutes found the waters to be roughly as corrosive as orange juice. “It would be inappropriate to consider these flavored sparkling waters as a healthy dental alternative to other acidic drinks,” that study concluded."
