Let’s tackle the big fear: “Sparkling water will rot my teeth!” Relax. The truth is more subtle. When carbon dioxide dissolves in water, it forms weak carbonic acid—that’s what gives it the tang. This makes sparkling water slightly more acidic (pH around 3–4) than still water (pH 7).
But here’s the kicker: it’s still way less acidic than soda, which packs a pH of 2.5 and is loaded with enamel-eating sugars. Plain sparkling water is about as harmful as a glass of orange juice—and nobody panics about that. The real enemy is flavored sparkling waters with added citric acid or sugar. Stick to unflavored, and you’re golden.
Practical tip: drink through a straw to bypass your front teeth, and don’t sip it over a whole day. A quick fizz session is fine; a marathon is what wears down enamel. Think of it like a date—short, sweet, and over before it gets messy.
