Is Sparkling Water Bad for Your Teeth?

By Lovik Mirzaeian, DDS. Updated September 2026.

Plain sparkling water is mildly acidic and slightly harder on enamel than still water, but it is nowhere near soda, and for most people drinking it in normal amounts it is fine. The problem starts with flavoured, citrus and sweetened versions, which are considerably more acidic and can wear enamel over time if you sip them all day.

The question comes up constantly, and the honest answer is that it depends on which sparkling water and how you drink it. Here is where the line sits.

Why Acid Matters More Than Bubbles

Enamel starts dissolving when the pH in your mouth drops below about 5.5. Anything more acidic than that, held against teeth for long enough, softens the surface. Saliva neutralises the acid and re-hardens enamel within about half an hour, so an occasional acidic drink does no lasting harm. Constant sipping never gives saliva the chance.

Carbonation adds carbonic acid, which is what brings sparkling water below neutral. On its own it is a weak acid, and plain sparkling water typically lands somewhere around pH 5 to 6. Right at the edge, and mild.

Where Different Drinks Fall

Still water sits at neutral, around 7.

Plain sparkling or mineral water, around 5 to 6. Mildly acidic, and the minerals in some brands soften the effect further.

Flavoured sparkling water, often 3 to 4. The citric acid used for flavour, even in unsweetened versions, is what drives this. Lemon and lime flavours are the most acidic.

Soda, around 2.5 to 3.5, with sugar on top. This is the category to worry about, and it is not close.

Energy and sports drinks, similar to soda and sometimes worse.

Pure lemon juice, around 2. Adding a slice of lemon to water moves it a long way down the scale.

The lesson is that the fizz is not the issue. The added acid is.

Does the Research Say It Harms Teeth

Studies that soak extracted teeth in plain sparkling water for days show a small amount of surface change, far less than soda. In the mouth, with saliva doing its job and the drink passing through in seconds, the effect on plain sparkling water drinkers appears minimal. The American Dental Association position is that plain sparkling water is generally fine for teeth and a far better choice than sugary or acidic alternatives.

Flavoured versions have less research behind them but a much lower pH, and dentists do see erosion in people who drink them constantly.

How to Drink It Without Worrying

Have it with meals rather than sipping over hours. Food raises saliva flow and shortens how long acid sits on teeth.

Drink it fairly quickly rather than nursing a can for an afternoon. Total acid exposure time is what matters, not the quantity.

Rinse or drink some still water afterwards, especially with flavoured versions.

Wait thirty minutes before brushing. Brushing while enamel is softened scrubs it away. This applies to anything acidic, including fruit and wine.

Skip the lemon slice if you drink a lot of it. And if you use it as your all-day drink, make it plain rather than flavoured.

Signs Acid Is Getting to Your Enamel

Teeth that look yellower, because thinning enamel lets the dentin underneath show through. Edges of front teeth becoming translucent or slightly see-through. New cold sensitivity, covered in our piece on why teeth hurt with cold drinks. Small dents or cupping on the chewing surfaces of back teeth. Fillings that suddenly seem to stand proud of the tooth around them, because the tooth has worn down and the filling has not.

Erosion is painless while it happens, and enamel does not come back. It is worth catching, and it is one of the things looked for at a routine dental exam.

What About Other Popular Drinks

Kombucha is acidic and often sweetened, closer to soda than to water. Iced coffee is mildly acidic and stains. Iced tea is mild unless sweetened or flavoured with lemon. Diet soda has no sugar but the same acid as regular, so it still erodes. Alkaline water does nothing measurable for teeth one way or the other, since saliva sets the pH within moments anyway.

If you are choosing sparkling water over any of those, you are already making the better choice for your teeth. Plain and with meals makes it better still.

Frequently Asked Questions

Is sparkling water bad for your teeth?

Plain sparkling water is mildly acidic but far gentler than soda, and drinking it in normal amounts is fine for most people. Flavoured and citrus sparkling waters are considerably more acidic and can erode enamel if sipped all day. The added acid, not the bubbles, is the issue.

Is flavoured sparkling water worse than plain?

Yes, noticeably. The citric acid used for flavour brings the pH down to around 3 to 4, close to soda territory, even in unsweetened versions. Lemon and lime flavours are the most acidic. Plain sparkling water sits around 5 to 6, which is much milder.

Should I brush my teeth right after sparkling water?

No. Wait about thirty minutes. Acid temporarily softens enamel, and brushing during that window scrubs softened enamel away. Rinse with still water instead, then brush later. This applies to anything acidic, including fruit and wine.

Is sparkling water better than soda for teeth?

By a wide margin. Soda is far more acidic and contains sugar that feeds the bacteria causing decay. Diet soda removes the sugar but keeps the acid. Plain sparkling water has neither problem to any meaningful degree.
