Let’s talk about carbonated water and teeth. The question is sparkling water or seltzer water or carbonated water, are those bad for your teeth?

carbonated water

The short answer is that carbonated water is not as bad for your teeth as drinking soda, diet soda, juice, or any other sweetened drink. But that’s only if it’s free of sugars and artificial sweeteners. Of course, you all know about all those flavored seltzer waters. If your sparkling carbonated water is flavored, then you immediately lose the leg up that you get by skipping the soda. So if you are someone who is looking for a healthier sugar-free alternative to soda, seltzer is a good alternative.

However regular water really still is better.

This is because the typical PH level inside of our mouths is between six and seven. Tap water is usually around six point five to eight. However carbonated water has a lower PH level so it is slightly more acidic than tap water averaging anywhere from 3 to 4.5 or higher on the PH scale, depending on which brand you get. But again it’s still not as bad as soda where the PH level is around 2.4.

The lower the PH means it’s more acidic which means that your tooth enamel is more likely to weaken and get cavities. Although enamel is the hardest substance in the entire human body, if you expose it to acidic liquids all day every day, it will still erode eventually. In all, drinking tap water is always best for your mouth, but carbonated water is definitely not as bad for your teeth as regular soda.

Let’s go over the four things you can do to better your dental health while drinking carbonated water.

drink carbonated water with food
  1. Drink with food. Food helps neutralize acids from your drinks or other desserts. It’s always better to drink carbonated water at meals than to sip on it all throughout the day.
  2. Use fluoride every night. Fluoride mouthwashes and toothpaste help counteract the effects of enamel erosion. So if you’re a big seltzer drinker, be sure that fluoride is in your dental home care routine.
  3. Drink tap water afterward or at least rinse your mouth with tap water after drinking carbonated water. Nothing is as good for your teeth as drinking plain tap water.
  4. Talk to your dentist if you are having any tooth sensitivity or if you’ve been noticing any issues in your mouth lately. Be sure to tell your dentist or your dental hygienist about how frequently you are drinking carbonated water. So they can better assess your situation.
