Is Sparkling Water Bad for Your Teeth? What You Need to Know

Sparkling water is often viewed as a healthier alternative to sugary soft drinks, offering a refreshing fizz without the added sugar and calories.

For anyone trying to stay hydrated while cutting down on sweetened beverages, it can seem like the perfect option.

But is sparkling water bad for your teeth?

While it may be better for your body, its impact on oral health is worth a closer look.

This guide breaks down the facts so you can enjoy your favourite fizzy drink without putting your enamel at risk.

How sparkling water affects your teeth

The fizz in sparkling water comes from carbon dioxide, which turns into carbonic acid when dissolved in water.

This acid gives sparkling water its signature tang, but also lowers its pH, making it slightly acidic.

Why does acidity matter?

Your enamel, the hard outer layer of your teeth, is vulnerable to acid exposure.

Over time, acidic drinks can weaken enamel, increasing the risk of sensitivity, tooth decay, and erosion.

That said, the acidity in plain sparkling water is usually quite low, much lower than drinks like orange juice, cola, or energy drinks.

This makes it a far less harmful option in comparison.

Sparkling water vs sugary and acidic drinks

When it comes to protecting your enamel, not all fizzy drinks are created equal.

• Sugary sodas are highly acidic and packed with sugar, creating the perfect conditions for decay-causing bacteria.
• Fruit juices and energy drinks often combine natural or added sugars with high acidity, increasing enamel erosion risks.
• Flavoured sparkling waters may seem like a safer choice, but many include citric acid or other additives that lower the pH and heighten acid exposure.

By contrast, plain sparkling water contains no sugar and only mild acidity, making it a far better choice for your teeth.

If you prefer flavoured versions, always check the label. Look out for added acids or sweeteners and try to choose options with minimal ingredients.

How to drink sparkling water without harming your teeth

You don’t need to ditch sparkling water altogether to protect your enamel. These smart habits mean you can enjoy it while keeping your teeth safe:

• Rinse with plain water: After drinking sparkling water, rinse your mouth with still water to wash away any lingering acids.
• Stick to plain options: Choose unflavoured sparkling water without added sugars or acids. Flavoured varieties may increase the risk of enamel erosion due to added ingredients.
• Practice good oral hygiene: Brush your teeth twice a day with fluoride toothpaste, floss regularly, and visit your dentist for routine check-ups. Fluoride helps to strengthen enamel and protect against acid damage.
• Avoid brushing immediately: Acidic drinks can temporarily soften enamel. Wait at least 30 minutes before brushing your teeth to allow enamel to re-harden and avoid causing additional wear.
• Limit prolonged sipping: Try to finish your sparkling water in one sitting rather than sipping throughout the day to reduce acid exposure.

So, is sparkling water bad for your teeth?

The good news is that plain sparkling water is generally safe for your teeth when consumed in moderation.

It’s far less damaging than sweetened fizzy drinks, juices, or sports drinks. However, excessive consumption or regular use of acidic flavoured varieties may increase the risk of enamel wear.

As always, your dentist can offer tailored advice based on your individual oral health and habits.
