Short answer: Chronic bad breath that doesn’t respond to better brushing is often a bacterial-balance issue, not a technique issue — Burst’s Oral Health Probiotics use BLIS K12™ and BLIS M18™ strains to help rebalance the oral microbiome rather than mask odor.
Why some bad breath doesn’t respond to brushing harder
When odor-causing bacteria are simply out of balance in the mouth, extra brushing doesn’t fix the root cause.
What’s actually in the formula
One of the highest available concentrations of BLIS K12™ and BLIS M18™, combined into a proprietary blend designed to feed healthy bacteria and fight the bacteria responsible for bad breath and tonsil stones. 45 chewable lozenges make up a six-week supply; shelf-stable, no refrigeration needed; dairy-free, nut-free, gluten-free, soy-free, non-GMO.
Who’s a good candidate
Patients who’ve already ruled out the obvious causes (poor technique, tongue coating, dry mouth, unaddressed decay) and still deal with persistent breath issues.
Setting expectations honestly
This is a maintenance product taken consistently over a six-week course, not an instant fix like a mint or breath strip — the two solve different timeframes of the same problem.
