Why TheraBreath Works
The Science Behind the Orange Cap
Targets the Root Cause
Bad breath comes from anaerobic bacteria producing sulfur compounds (VSCs). TheraBreath’s sodium chlorite creates an oxygen-rich environment where those bacteria simply cannot survive.
Works Instantly, Lasts 12 Hours
A 2018 double-blind clinical trial confirmed TheraBreath significantly reduces hydrogen sulfide and methyl mercaptan — the two main bad-breath compounds — for up to 12 hours per use.
No Alcohol = Healthier Mouth
Alcohol-based mouthwashes like Listerine kill bacteria but also dry out your mouth — and a dry mouth actually produces more bad bacteria. TheraBreath breaks that cycle entirely.
ADA Accepted — Real Credibility
The American Dental Association only accepts products that pass safety and efficacy reviews. TheraBreath holds ADA acceptance — and so does your dentist’s trust in recommending it.

“I’ve tried everything. This is the one.”
Struggled with bad breath for years despite brushing twice daily. Started using TheraBreath two weeks ago and the difference is genuinely night and day. No burn, no harsh taste — and my partner actually commented unprompted.

“My dentist actually recommended this”
My hygienist brought it up before I did. Switched from Listerine — the alcohol was drying my mouth out so badly. TheraBreath is gentle, works all morning and I don’t have to re-brush before meetings anymore.

“Worth every penny, buying the 2-pack”
I was skeptical — it costs more than drugstore brands. But the value is there. It actually addresses the problem rather than just masking it. Genuinely feel fresh-confident for my whole morning commute.
