BLIS Teeth and Gums Oral Probiotic with M18 - Peppermint Lozenges for Dental Health Plaque Reduction and Fresh Breath (30 Count)

BLIS stands for Bacteriocin-Like Inhibitory Substances — the natural antimicrobial peptides produced by S. salivarius M18 and K12 strains. BLIS Technologies is a New Zealand-based company that originally discovered these strains and holds the patents. They've been researching oral probiotics for over 25 years. When other brands use 'BLIS K12' or 'BLIS M18' in their products, they're licensing the strains from this company. Buying BLIS direct means you're getting the original.

S. salivarius M18 fights cavities through multiple mechanisms: it produces antimicrobial peptides that directly kill Streptococcus mutans (the primary cavity-causing bacterium), creates enzymes that break down plaque biofilm on tooth surfaces, reduces oral acidity (acidic environments promote tooth decay), and competes with harmful bacteria for space and nutrients. The 81% caries reduction figure comes from clinical studies tracking dental outcomes in participants using M18 vs. placebo over extended periods.

If your primary concern is cavities and plaque, BLIS M18 alone gives you the highest concentration of the most relevant strain from the original source. If you also want bad breath support and gum inflammation help, a multi-strain product that includes K12 and L. reuteri alongside M18 offers broader coverage. It's like choosing between a specialist and a general practitioner — both valid, depends on your specific needs.

Yes — BLIS Teeth & Gums is suitable for children aged 5 and over who can safely dissolve a lozenge in their mouth without choking risk. BLIS also offers a ToothGuard product specifically formulated for children ages 3+. M18 is particularly relevant for children's dental health because it targets the cavity-causing bacteria that are most active during the years when permanent teeth are developing.

BLIS Technologies is based in Dunedin, New Zealand, where the original research on S. salivarius K12 and M18 was conducted at the University of Otago. New Zealand has stringent quality standards for health supplements. The product is manufactured under high-quality standards in New Zealand and exported worldwide. The New Zealand origin actually adds credibility — this isn't a brand that licensed someone else's research, it's the company that did the original science.
