Is Sparkling Water Bad For Your Teeth?

Posted by: Paxton Dental Care Categories: Dental Tips



As the new year begins many of us are trying to choose healthier options. This includes attempting to make smarter choices in our choice of drink. A choice for many is to forego sugary sodas and choose carbonated water. The thought is we will choose a lower calorie drink that is also less harmful to our oral health. But is sparkling water safer for our teeth and gums?

What Is Sparkling Water?

Sparkling water is made by dissolving carbon dioxide in water, creating carbonic acid. This chemical process just adds bubbles. It does not add sugar, calories, or even caffeine. Tonic water, club soda, and mineral water are all types of readily available carbonated water, but these have added sodium, vitamins, or sweeteners, so it’s important to read the label.

Is Sparkling Water Harmful To Our Teeth?

Yes, sparkling water can harm your teeth. While sparkling water is only slightly more acidic than regular tap water it has the power to do damage to our teeth’s enamel through a process called tooth erosion (wearing away of the outer layer of our teeth due to acids).


Some of the causes of tooth enamel erosion include:

-Consuming excessive amounts of sodas (high levels of phosphoric and citric acids)

-Fruit drinks (some acids in fruit drinks are more erosive than battery acid)

-Dry mouth or low salivary flow (xerostomia)

-Diet (high in sugar and starches)

-Acid reflux disease (also called GERD)

-Gastrointestinal problems

-Medications (for example aspirin and antihistamines)

-Genetics

-Environmental factors (friction, wear and tear, and stress)

Research has shown that sparkling water has a pH (measure of aciditiy) of approximately 3 (with 5 being neutral). The researchers used extracted teeth and placed them in glasses filled with various types of sparkling waters. What they found was quite surprising. Sparkling water does in fact have the acidity to erode tooth enamel. In fact, the researchers found that the sparkling water compared to orange juice in terms of its erosive effect.

Sparkling Water Conclusion

While the research showed that the sparkling waters can erode tooth enamel, it is important to note that if used in moderation it is a perfectly healthy alternative to sodas and energy drinks. Remember to practice good oral hygiene after using these drinks and you should have little to worry about in terms of your dental health.
