For the 3pm coffee breath.
Mints cover it up; nothing addresses where it comes from. BLIS K12 is the probiotic strain studied for the bacteria that actually causes it.

Brushing, flossing, the electric toothbrush, the water flosser — and somehow the cleaning is still uncomfortable, and the breath in the afternoon isn't great by 3pm. Two mint chewables a day add what brushing can't: the good bacteria that competes with the bad, and the nutrients your gum tissue is asking for from the inside.

The formula
A quieter system

Breath
Mints cover it up; nothing addresses where it comes from. BLIS K12 is the probiotic strain studied for the bacteria that actually causes it.

Gums
If the hygienist's pick makes you wince and the receptionist always asks if you flossed — your gum tissue may just need nutrient support, not more pressure.

Routine
Brush. Floss. See the dentist. Then add this. It's the daily piece that lives next to your toothbrush, not instead of it.

01
One capsule, twice a day, with water. No timing dance, no stimulant cycling.

02
Most people notice a steadier daytime baseline within 7–10 days — not a hit, a settling.

03
By week 3–4, the 3am wake-up softens. You’ll know it’s working when you stop noticing the time.

Proprietary blend

A clinically-studied probiotic strain that naturally colonises the healthy oral cavity. Studied for supporting fresh breath and oral-microbiome balance through competitive exclusion of less-desirable bacteria.

BLIS K12 Probiotic
“I’m not really sure why my comment here about what probiotics I use is being downvoted. Is it for giving people a source to find them and a discount code? I mean, what is there to downvote there? The ingredients can be easily Googled and you can find research articles on the information I’ve posted. I don’t see other people mentioning probiotics in general let alone products that have ingredients with research to show proven effectiveness. If other people want to jump in on the conversation and start offering helpful advice or suggestions then I’ll take those downvotes more seriously (jk). Until then maybe don’t try to come for me when literally all I do in this sub is help people 🌈🙌🏻”Read the original
Xylitol
“I tackled this by searching specifically for a dentist with a great reputation for caring about patients and who specialized in handling patients with highly sensitive teeth. The first session was a bit stressful, but they were overwhelmingly kind and truly wanted to help - that got me settled enough to go back and finish all the repairs. I strongly encourage you to do some research to find a similar dentist!”Read the original
“Lots of excellent, sensible, mature advice in here! I second it all, and would like to add my contribution: When I am at the dentist, I pretend I am a robot and I am getting repairs done. This makes all the whizzy buzzy sharp metal tools make sense. Also they feel less creepy and more appropriate for being poked inside my head. And I'm quite good at holding still and ignoring what's going on. Because I am a robot! ;D (Sometimes I'm a robot when I'm brushing my teeth, too. It's generally quite useful.)”Read the original
“Yes. I have spent over $10k on my teeth. Cavities, root canals, crowns. My teeth even chipped off. After the treatment, my new hyperfocus was dental hygiene. I was so good about it until I got overwhelmed by other stuff and now I just manage to brush in the mornings and then needed to get crowns and cavities filled again. Some tips that help is trying low-effort healthy habits: Get a xylitol chewing gum. It can help prevent cavities. A fluoride mouthwash. These can't really replace brushing but they're better than nothing. I've heard good things about the water flosser (waterpik). Easier than string floss. You could use an interdental brush while watching TV or other stuff. I floss while watching my favorite show so I can look forward to it. Maybe do something similar when you brush.”Read the original
“I ***think*** the concept is that chewing gum increases your saliva, which is good for combating bad bacteria in your mouth and also reducing acidity. Xylitol is usually specified for beneficial gum chewing because I'm guessing it is a sugar substitute and less damaging to your teeth than actual sugar would be. This is my general knowledge of it at least.”Read the original

Honest answers
No — and we're explicit about that. Mechanical removal of plaque (brushing + flossing) is non-negotiable. This is nutrition-side support that complements good oral hygiene.
BLIS K12 is a friendly Streptococcus salivarius strain that competes with the bacteria associated with bad breath. By colonising the same oral real estate, it crowds them out.
Fresh-breath effects from BLIS K12 are often noticeable within the first week. Gum-tissue maintenance benefits build over 8–12 weeks.
After brushing — morning and night. The chewable dissolves in the mouth, allowing the BLIS K12 to colonise the freshly-cleaned oral cavity.
Natural mint — light and clean. Not toothpaste-strong, not gum-sweet.
Yes for humans — xylitol has decades of safe-use research at the doses used in oral-wellness products. Important caveat: xylitol is highly toxic to dogs. Keep this product well away from pets.
Yes — they don't conflict.
