Is Sparkling Water Bad for Your Teeth?

Is Sparkling Water Bad for Your Teeth?

Sparkling water has become a favourite refreshment for many, offering a fizzy, flavourful alternative to sugary soft drinks. But there’s been a growing concern: can sparkling water harm your teeth? Let’s take a look at what the experts say and whether it’s as bad for your teeth as some might think.

What Makes Sparkling Water Different?

Sparkling water gets its fizz from carbon dioxide, which when dissolved in the liquid, forms carbonic acid. This is what gives sparkling water its characteristic sharp, bubbly taste. Unlike sodas, sparkling water generally doesn’t contain any added sugar, but there’s still the question of whether its acidity might be harmful to your teeth.

How Does Acid Affect Teeth?

Acidic drinks can be damaging to your teeth over time. The acid erodes enamel, the hard outer layer that protects your teeth. Once enamel is worn away, it doesn’t grow back, and your teeth become more vulnerable to decay and sensitivity.

• pH Levels Matter: Pure water has a neutral pH of 7. Sparkling water tends to have a pH around 3 to 4, making it mildly acidic. While it’s not as acidic as sodas (which usually have a pH of around 2), it’s still on the acidic side.
• Sugar + Acid = A Bigger Problem: One of the reasons sugary drinks are so harmful to teeth is because sugar + acid creates a perfect environment for tooth decay. Fortunately, most sparkling waters don’t contain sugar, so they’re less likely to contribute to cavities.

Flavoured Sparkling Water and Additives

If you’re someone who enjoys flavoured sparkling water, you may want to proceed with a little caution. Many flavoured waters (even those without added sugar) contain citric acid, which is an additional acid that can lower the pH and increase the risk of enamel erosion. Flavoured waters with added sweeteners can pose an even greater risk, as they introduce both acid and sugar into the equation.

What Do the Experts Say?

Research shows that the effect on enamel is minimal compared to sugary sodas or fruit juices. However, they do recommend drinking it in moderation, as regular exposure to acidity — even from sparkling water — can lead to slight enamel wear over time.

How to Enjoy Sparkling Water Without Damaging Your Teeth

You don’t have to give up sparkling water entirely. Just follow a few simple tips to keep your teeth in top shape:

1. Drink in Moderation: Try not to sip sparkling water constantly throughout the day. Give your teeth a break in between.
2. Use a Straw: Drinking through a straw reduces the amount of time the acidic liquid spends in contact with your teeth.
3. Rinse with Water: After you’ve enjoyed your sparkling water, rinse your mouth with still water to help neutralise the acid.
4. Wait Before Brushing: Don’t rush to brush your teeth right after drinking sparkling water. The acid can temporarily soften your enamel, and brushing straight away can cause damage. Wait around 30 minutes before reaching for your toothbrush.
5. Opt for Plain Over Flavoured: If you can, go for plain sparkling water. Flavoured versions can have added citric acid or sugar, which increases the risk to your enamel.

Plain sparkling water is a much better choice for your teeth than sugary soft drinks. When enjoyed in moderation, it’s not likely to cause significant harm. However, flavoured or sweetened sparkling waters should be enjoyed with caution. As long as you’re mindful of how often you drink it and follow some simple tips for protecting your enamel, you can still enjoy that refreshing fizz without worrying too much about your smile.
