Real gums. Real research.
When your oral microbiome is balanced, your gums don't need a war fought on them every day — they need the bacteria that protects them.
average study duration showing measurable improvement in gingival/bleeding index with daily oral probiotic use
major periodontal pathogens shown in lab research to be suppressed by the K12/M18 strain combination
clinically studied strains in every lozenge, chosen for documented roles in oral health
Figures reflect published clinical and laboratory research on the individual probiotic strains used in this formula, not a survey of TervaLabs customers specifically.
Finally Conquer Gum Disease
Gingivitis and periodontal disease aren't just about how much bacteria is in your mouth, they're about which bacteria wins. A healthy gum line depends on a population of protective bacteria that competes directly with the species responsible for inflammation and bleeding. When that balance tips, even diligent brushing and flossing can't fully fix it on their own.
That's where targeted oral probiotic strains come in. Introducing healthy bacteria to dominate your gum line.
- Streptococcus salivarius K12 & M18 — among the most studied strains in oral health, shown to suppress the growth of major periodontal pathogens, including P. gingivalis, and calm the inflammatory response in gum tissue.
- Lactobacillus reuteri — clinically tested for its ability to reduce bleeding on probing and improve gingival health scores with consistent use.
- Lactobacillus paracasei — competes directly against harmful oral bacteria, helping crowd them out rather than indiscriminately reducing bacteria overall.
- Bifidobacterium lactis — supports a healthier microbial balance along the gum line.
- Lactobacillus brevis — shown in clinical research to successfully colonize oral tissue, not just pass through.
- Streptococcus A12 — a naturally occurring commensal strain studied for interfering with how harmful bacteria communicate and spread.
Seven targeted strains. Eleven billion CFU. Delivered as a slow-dissolving lozenge built to stay at the gum line long enough to actually make a difference.
How It Works
One lozenge each night. Here's what happens inside your mouth.
Dissolve One Lozenge After Brushing
Place one lozenge on your tongue after your morning and nightly brush and let it dissolve slowly. Don't chew it — the slow release is what delivers the strains directly to your gum line.
Protective Bacteria Resettle Your Gum Line
Unlike capsules that dissolve in your stomach, the lozenge format deposits K12, M18, and the other studied strains exactly where they need to be — recolonizing the gum line and crowding out the bacteria associated with inflammation and bleeding.
Notice Less Bleeding, Calmer Gums
Many people notice less bleeding when flossing within the first 3–4 weeks. Results continue to build as the protective strains establish and your oral microbiome rebalances over 8–12 weeks.

What Our Customers Are Saying
Thousands of people have made TervaLabs Oral Probiotic part of their daily routine. Here's what they experienced.
"My hygienist actually asked what I changed"
I've flossed every night for thirty years and my gums still bled at every cleaning. I'd basically accepted it as "just how my mouth is." Eight weeks on TervaLabs and at my last appointment my hygienist paused, re-checked her notes, and asked what I'd changed. No bleeding at any site for the first time in years. I actually got a little emotional in the chair — I didn't realize how much I'd written this off as permanent.
"I stopped checking my gums every morning"
I'd gotten into this habit of running my tongue along my gum line constantly, checking if it had pulled back any further. Drove my husband a little crazy. About three weeks into using TervaLabs I realized I'd gone a full day without doing it. By week six I'd basically stopped the habit entirely. I don't know exactly when it happened — I just noticed one day that I wasn't worried anymore.
"The K12/M18 combination is the real deal — I researched this extensively"
I'm a retired nurse and I don't take supplement claims at face value. Before buying I actually looked into the clinical research behind oral probiotic strains. Most products either use the wrong strains or rely on capsules that never reach the gum line. TervaLabs uses K12 and M18 in a slow-dissolving lozenge, which lines up with what the published research actually supports. Ten weeks in, and my pocket depths at my last periodontal check were the best they've been in four years.
"Tried mouthwash and harder brushing first — that was the mistake"
For two years my answer to bleeding gums was to brush harder and rinse more. It never actually got better, just cycled between bad and slightly less bad. Once I understood that the antiseptic rinse might be wiping out the bacteria that was supposed to be protecting my gums in the first place, I switched to TervaLabs instead. Within a month the bleeding I'd had for two years was gone. Wish I'd known this years ago instead of fighting my own mouth.
"My dentist mentioned grafting — I wanted to try this first"
My periodontist brought up grafting for two sites that kept getting worse despite good hygiene. I wasn't ready for surgery, so I asked for time and started TervaLabs in the meantime. At my recheck twelve weeks later, both sites had stabilized — no further recession, no bleeding. We're holding off on surgery for now and just monitoring. I'm not saying it's a replacement for a procedure if you truly need one, but it bought me time I didn't think I had.
"90 days in and I finally feel like I'm ahead of it"
My mom lost most of her teeth in her sixties and I've been quietly terrified of ending up the same way. Every cleaning I'd brace myself for bad news. Three months on TervaLabs and my last visit was the first one in years where nothing got worse — a couple of spots actually improved. I'm not naive enough to think it's a miracle, but for the first time I feel like I'm ahead of this instead of just watching it happen. Already ordered my next bottle.
