Is Sparkling Water Bad for Your Teeth?
Plain sparkling water is not bad for your teeth — it's only mildly acidic and far gentler on enamel than soda or citrus-flavored seltzers. The real damage comes from added sugar and citric acid, not carbonation.
What the research shows
Studies rank plain sparkling water close to still water for enamel. Flavored, sweetened or citrus seltzers are far more erosive. Choose sparkling water with nothing added.
