Fresh breath is one of those often-overlooked details that can make or break your confidence.

As a beauty editor, I’m always meeting new people – whether it’s at product launches, intimate celebrity interviews, or quick coffee catch-ups with brand reps. In these moments, I’ve learned that maintaining a polished presence is also about how you carry yourself, and fresh breath plays a part in that.

Even with a solid oral hygiene routine, I wondered if my breath was holding up after hours of socialising. That’s when I discovered my game-changing hack: TheraBreath Oral Rinse.

The Story Behind TheraBreath

TheraBreath has a heartfelt origin story. It was created by Dr Harold Katz, a dentist and bacteriologist, to help his daughter overcome persistent bad breath.

What started as a father’s personal mission soon evolved into a trusted, science-backed brand.

TheraBreath’s patented oxygenating formula targets the bacteria responsible for bad breath, offering lasting freshness without the burn of alcohol or harsh ingredients. Free from alcohol, dyes, and artificial flavours, it’s also gentle and suitable for sensitive mouths.

Pssst! I also recently spotted TheraBreath’s Oral Rinse in an episode of Single’s Inferno 4. One of the girls, Kim Arin, had it on her vanity – proof that even on a high-stakes dating show, fresh breath is a priority.

To truly understand how the TheraBreath Oral Rinse stands out, I put it through four different tests. Keep reading for the results.

TheraBreath Oral Rinse Review: Putting it Through 4 Tests

Test #1: Fresh Breath Challenge

For lunch, I whipped up a hearty tomato-based fusilli pasta loaded with three cloves of garlic. Anyone who’s had garlic-heavy meals knows how stubborn that smell can be.

After my meal, I rinsed my mouth with TheraBreath for 90 seconds.

The result? No trace of garlic breath – even my partner confirmed it! It was a clear testament to TheraBreath’s effectiveness.

Test #2: Long-Lasting Challenge

I incorporated the TheraBreath Oral Rinse into my daily routine, swishing for 90 seconds after brushing.

The results were impressive: I enjoyed 12-hour fresh breath that carried me through my day – from my breakfast to evening meetings.

The ease of use made it a seamless addition to my routine, and with consistent use twice daily, I experienced lasting freshness for up to 24 hours.

When used twice daily, the effects were even more remarkable, leaving me with fresher breath upon waking. Once again, my partner served as the ultimate verifier.

Test #3: The Onion Challenge

This one was fun and surprisingly revealing.

Following the provided instructions, I chopped an onion and split it between two sealable jars. One jar was filled with TheraBreath, while the other held a leading brand of mouthwash.

After sealing and letting them sit for 30 minutes, I opened both jars. The jar with TheraBreath had a faint, almost unnoticeable hint of onion, while the other jar retained a strong onion odour.

It’s a win for TheraBreath!

Test #4: Flavour and Mouthfeel Challenge

The TheraBreath Oral Rinse comes in two variants: Invigorating Icy Mint and Mild Mint.

The Invigorating Icy Mint provides a bold, energising freshness, while the Mild Mint offers a gentler, soothing experience.

Personally, I gravitate towards the Mild Mint variant. It’s not as intense, but it still delivers lasting freshness without the uncomfortable burn I’ve experienced with other mouthwashes. Even some alcohol-free options can feel a tad too “spicy”, but TheraBreath’s formula is truly gentle.
