Flavored seltzer water and your health

Written by: Melissa Miller


Many people are turning to seltzer, a type of sparkling water, as a healthier alternative to drinking soda. In fact, the amount of seltzer sold in the US doubled between 2010 and 2019. Though some experts have concerns that seltzer may lead to tooth erosion, seltzer has many positive health benefits. Here’s what you need to know about the risks and benefits of drinking seltzer.

What is seltzer?

Seltzer water is water that has been infused with carbon dioxide gas under pressure. Carbonation causes small bubbles to form, giving the water an effervescent quality. Common forms include sparkling natural mineral water, club soda, and commercially produced sparkling water. Seltzer water is slightly acidic because water and carbon dioxide react to produce a weak acid called carbonic acid. However, it is not as acidic as many other juices and sodas.


Can seltzer affect your dental health?

The American Dental Association warns against drinking too many acidic drinks. Some natural flavors like lemon acids can wear away the hard outer layer of enamel that protects your teeth from decaying. This can lead to cavities and gum disease. The ADA recommends limiting seltzer consumption to a few drinks a week.

Does carbonated water hydrate as well as regular water?

Seltzer water is plain water that has carbon dioxide added under pressure to create that bubbly effect that many people love. So if you’re obsessed with seltzer, there’s good news: it counts towards your daily water intake totals.
