Probiotic Breath Spray Australia (2026):
Fresh Breath Without the Sugar
Most breath fresheners just cover things up with sugar, alcohol or a blast of mint. A probiotic breath spray takes a different approach: it adds friendly bacteria that naturally live in a healthy mouth, with no sugar and no alcohol. Here's how probiotic breath sprays work, how they compare with mints and gum, and what to look for before you buy one.

A probiotic breath spray freshens your mouth by adding friendly oral bacteria rather than just masking odour with sugar or alcohol. Look for named, clinically studied strains like BLIS K12™ and BLIS M18™, zero sugar and zero alcohol. The HolyH₂O Cool+ Spray ticks all three, in a rechargeable nano-mist you can carry in your pocket.
What Is a Probiotic Breath Spray?
A probiotic breath spray is an oral spray that delivers beneficial bacteria into your mouth. Your mouth is home to billions of bacteria, and the balance between them shapes how your mouth feels and smells. Instead of overpowering odour with a strong flavour, a probiotic spray adds the friendly strains that naturally belong there.
Adds friendly bacteria instead of just covering things up for ten minutes.
Sugary mints and alcohol sprays can leave your mouth drier and sticky.
A fine mist reaches your whole mouth, not just the tip of your tongue.
Cool+ charges by USB-C, so there are no batteries to buy.
Probiotic Spray vs Mints vs Gum
Mints and gum are quick but often sugary, and regular breath sprays usually rely on alcohol or strong flavour. A probiotic spray gives you the speed of a spray without the sugar.

Ready to ditch the mints? Cool+ gives you a fresh, clean mouth in about 3 seconds, with zero sugar and zero alcohol.
Shop Cool+ →The Strains That Matter
The strain names matter more than the word "probiotic" on the label. Cool+ uses two of the most researched oral probiotic strains, both forms of Streptococcus salivarius, a friendly bacterium that naturally lives in the mouth.
A clinically studied S. salivarius strain and the heart of that clean, fresh feel.
A second clinically studied S. salivarius strain that works alongside K12 to keep your mouth feeling clean and balanced through the day.
How and When to Use It
Click in a pod, spray once and go. There's nothing to chew and nothing to spit out, so it fits the moments where a mint feels awkward.
- ☕ After your morning coffee
- 💼 Before a meeting or a call
- ❤️ On the way to a date
- ✈️ Mid-flight or after a long drive
- 🏋️ After the gym, with a big drink of water
Pro tip: a dry mouth is one of the most common reasons breath goes stale, so keep your water up too. A spray plus regular sips of water is the easy combo. 💧
What to Look For in a Probiotic Breath Spray
Check for named strains, zero sugar and alcohol, and a refill system that makes it easy to keep using.
- "Probiotic" on the label with no named strain.
- Sugar or sweet syrups high up the ingredients list.
- Alcohol-based formulas that leave your mouth feeling dry.
- Single-use cans with nothing to refill.
Pick your flavour: Cool+ pods come in five sugar-free flavours, and a 3-pack of pods makes it easy to rotate.
