Is Sparkling Water Safe to Drink Daily? (Science-Backed 2025 Guide)

Updated on December 15, 2025

Sparkling water has become a popular alternative to soda and sugary drinks. With its fizzy texture and clean taste, many people now drink it daily. But questions remain about whether carbonation affects teeth, digestion, bones, or overall health. This guide explains what science actually says—without myths or marketing claims.

What Is Sparkling Water?

Sparkling water is water infused with carbon dioxide (CO₂) under pressure, creating bubbles. It may be naturally carbonated at the source or artificially carbonated during bottling. Unlike soda, plain sparkling water contains no sugar, calories, or caffeine.

Some versions include natural flavors or minerals, while others may contain added acids. Understanding the type you drink matters when evaluating daily safety.

Is Sparkling Water as Hydrating as Still Water?

Yes. Research shows that carbonated water hydrates the body just as effectively as still water. The presence of carbon dioxide does not reduce water absorption or hydration efficiency.

For people who struggle to drink enough water, sparkling water can actually improve daily fluid intake. Hydration benefits remain the same whether water is flat or carbonated.

Does Sparkling Water Damage Teeth?

This is one of the most common concerns. Sparkling water is slightly acidic due to carbonic acid formation, but its acidity is much lower than soda, fruit juice, or sports drinks.

Studies show that plain sparkling water causes minimal enamel erosion and is considered safe for teeth when consumed normally. Problems arise mainly with citrus-flavored waters containing citric acid.

• Avoid brushing immediately after drinking acidic beverages
• Drink sparkling water with meals
• Choose plain or lightly flavored varieties

Can Sparkling Water Cause Bloating or Gas?

Because it contains carbon dioxide, sparkling water can cause temporary bloating or burping—especially for people with sensitive digestion, IBS, or acid reflux.

However, some studies suggest carbonated water may improve swallowing ability and reduce constipation in certain individuals. If discomfort occurs, limiting intake or switching to still water may help.

Does Sparkling Water Affect Bones or Kidneys?

No. Carbonation does not weaken bones or damage kidneys. Earlier concerns came from cola studies, where phosphoric acid—not carbonation—was linked to bone issues.

Plain sparkling water has not been shown to reduce bone density or increase kidney stone risk in healthy individuals.

Is Sparkling Water Better Than Soda?

Yes—by a wide margin. Sparkling water contains no sugar, calories, or artificial sweeteners. Replacing soda with sparkling water significantly reduces sugar intake and supports better long-term health.

If you currently drink soda daily, switching to plain sparkling water is a positive and sustainable change.
