Seltzer waters like San Pellegrino, Perrier, and La Croix, once considered pretentious, are now the most popular drink-of-choice. We love to have spirited debates about which flavor is the best and how to pronounce names like Pamplemousse. With a zero-calorie count and touted mineral ingredients, they’ve become an accepted alternative to sodas, fruit juices, and beverages with added sugars. We’ve quickly turned to seltzer waters as our thirst-quenching staples—the much preferred cousin of boring regular water for its fruity, refreshing flavors and satisfying effervescent experience.

However, professors and researchers at the Department of Cariology and Comprehensive Care at New York University’s College of Dentistry have begun to worry if seltzer waters, like soda and fruit juice, can also be damaging to one’s oral health.

Is Seltzer Water Bad for Your Teeth? | Burke VA Dentist

Acid Content in Seltzer Waters is Bad News

Seltzer waters are a better choice than sugary drinks, so if you’re craving something sweet and bubbly, reaching for one of these is the more responsible option. But like any carbonated drink,  they’re acidic.  While seltzer waters aren’t as damaging as other indulgent drinks because they have a lower acidic content, drinking too many cans of La Croix in a day can compromise your teeth’s resiliency.

Your teeth are at risk when you consume carbonated beverages like seltzer water because manufacturers add pressurized carbon dioxide to achieve that bubbly texture. The act of carbonation makes the drink acidic, and acidity can erode your teeth’s enamel over time, making your teeth susceptible to erosion and decay. Tooth decay is accelerated when acid softens the tooth’s enamel, removing minerals from them and allowing bacteria to attack your teeth, eventually creating small holes, or cavities.

But it’s not just the carbonation that gives seltzer waters acidity. Flavors in seltzer waters can dramatically increase the acid content. A citrus-flavored version may be 100 times more acidic than a regular flavor.

Cut Back on the Quantity

How much seltzer you drink is the real factor in this issue. Just like drinking too much soda, fruit juice or coffee can have negative effects on your oral health, so can drinking too much seltzer water. Of course, the negative effects are to varying degrees but the consensus is to keep consumption to a healthy minimum. If you find yourself reaching for a can of seltzer water two or three times a day, try swapping it out for plain water—you may just be thirsty! Drinking more water will help reduce the amount of carbonation you ingest and satisfy your craving for something cold and refreshing.

Don’t Nurse that Drink

Your mouth has an incredible ability to self-heal within a half hour of coming into contact with acidic content—the saliva in your mouth helps the enamel on your teeth to harden back up. So the real problem occurs when you adopt the habit of nursing a carbonated drink. Say you’re at work and you open a bottle of San Pellogrino. You occasionally sip from the bottle over the course of a couple hours. While you might be savoring the enjoyment of the fizzy experience, you’re actually soaking your teeth in an acid bath for hours. Rather than allowing the seltzer to sit, make sure you consume the beverage in about five to ten-minute bursts so you can give your enamel time to harden again and disrupt the acidic process of softening. Again, if you’re looking for something to sip, plain water is a great choice (but maybe not raw water). 

Tooth wear and decay is often something can be prevented with a proper care and healthy lifestyle habits.
