Your Breath Is Still Off.
The gum you pop before every meeting. The mouthwash you use twice a day that stops working within the hour. The embarrassment of wondering if the person across from you can smell it. You know this feeling.
Sound familiar? You've probably already tried:
The problem wasn't your hygiene. It was that nothing was addressing the bacterial imbalance underneath.

The Clinically-Studied Formula Your Oral Microbiome Has Been Waiting For
Dental researchers have studied oral probiotics for fresh breath and gum health for years. Now it's available in a simple once-nightly lozenge — with the exact strains the clinical literature actually points to.
What Our Customers Are Saying
Thousands of people have made TervaLabs Oral Probiotic part of their daily routine. Here's what they experienced.
"My dentist actually asked what I changed"
I've had chronic bad breath my whole adult life. Gum, mouthwash, tongue scrapers — I tried everything. My hygienist always commented on my gum inflammation. Six weeks on TervaLabs and at my last cleaning she asked what I'd changed in my routine. My gums looked better and she said my breath was noticeably cleaner. I genuinely teared up a little. This is the first thing that's ever actually worked.
"I stopped carrying gum everywhere"
I'm a teacher so I'm talking in front of people all day. I used to go through two packs of gum a week just to feel okay about it. After about 10 days on TervaLabs I realized I hadn't reached for gum once. By week three I stopped carrying it altogether. The mint lozenge at night has become something I actually look forward to. It's such a simple habit and the difference has been genuinely life-changing for my confidence.
"The K12 strain is the real deal — I researched this extensively"
I'm a microbiologist and I spent a lot of time reading the research on oral probiotics before buying. Most products either use the wrong strains or the wrong delivery method. TervaLabs has both K12 and M18 in a lozenge format — which is exactly what the clinical literature supports. I've been using it for 8 weeks and the difference in my morning breath alone has been remarkable. Hard to overstate how much the delivery format matters here.
"Tried the cheap probiotic capsules first — huge difference"
I'll be honest — I tried a generic oral probiotic from Amazon first because I didn't want to spend more. Took it for six weeks and noticed basically nothing. Then I read about why lozenge delivery matters and why K12 specifically is the studied strain. Switched to TervaLabs. Within two weeks my morning breath was dramatically different. My girlfriend mentioned it before I even told her I switched. The format and the strains actually matter — you get what you pay for.
"My partner noticed before I did"
About two weeks in my partner said "your breath has been really fresh lately." I hadn't said anything about starting a new supplement. By week four I was waking up without that stale morning breath I'd had for years. I've also noticed my gums don't bleed when I floss anymore — that's been going on for years and I just assumed it was normal. One lozenge a night has quietly fixed two things I thought I'd have to live with forever.
"30 days in and I finally feel confident at work"
I work in sales and I'm in front of clients constantly. Bad breath was genuinely affecting my confidence — I'd avoid getting too close, keep meetings short, turn my head slightly when talking. One month on TervaLabs and that anxiety is completely gone. I'm not thinking about my breath anymore. I'm just showing up and doing my job. The mint flavor makes the lozenge feel like part of a routine, not a chore. Ordered the 3-bottle bundle and won't be stopping.
