Clinical Studies Behind a

Healthier Mouth

We don’t believe in oral care built on hype. We believe in evidence.

This page brings together clinical studies and research relevant to the FRESH 32 philosophy: less plaque, calmer gums, lower cariogenic bacterial load, and a more balanced oral environment.

The studies below most directly support the microbiome-focused side of the FRESH 32 system, especially oral probiotics, while reinforcing the brand’s broader prevention-first, gum-first approach.

SUPPORTS LOWER PLAQUE BUILDUP

Research on Streptococcus salivarius M18 shows meaningful reductions in plaque accumulation and biofilm over time, which fits naturally with FRESH 32's cleaner-mouth, prevention-first positioning.

  • Reduced plaque accumulation in clinical use
  • Cleaner tooth surfaces over time
  • Strong support for a daily preventive routine

MAY LOWER CARIES RISK

Clinical data also suggest that three months of BLIS M18 use can reduce overall caries risk scores, reinforcing the idea that oral probiotics can be a practical preventive tool, not just a niche add-on.

  • Lower caries-risk outcomes after 3 months
  • Strong prevention-focused angle
  • Useful for customers wanting long-term support

RELEVANT FOR KIDS AND ADULTS

The research spans preschool children and young adults, giving you a broader relevance story across life stages and different oral-health needs.

  • Evidence across multiple age groups
  • Useful for family-oriented positioning
  • Broadens trust and applicability

HELPS REDUCE GINGIVAL BLEEDING

A randomized clinical trial found that three months of M18 supplementation significantly reduced gingival bleeding, making this one of the clearest study-backed benefits for customers dealing with irritated or reactive gums.

  • Significant reduction in gingival bleeding
  • Relevant for sensitive-gum users
  • Supports a calmer daily oral-care routine

BUILT AROUND ORAL BALANCE, NOT STERILIZATION

Several of these studies support a replacement-therapy or bacteriotherapy logic: instead of trying to wipe everything out, oral probiotics help promote a healthier balance inside the mouth. That aligns well with FRESH 32's microbiome-conscious brand direction.

  • Supports beneficial oral ecology
  • Moves beyond "kill all bacteria" thinking
  • Fits a microbiome-first oral-care story

BEST FIT FOR FRESH 32 ORAL PROBIOTICS

Of all current FRESH 32 products, these studies most directly support the oral-probiotic side of the range. They also complement the wider FRESH 32 "engineered system" story, where brushing, gentle cleaning, and oral-balance support work together rather than separately.

  • Most directly supports Oral Probiotics
  • Reinforces the microbiome-first approach
  • Complements the full FRESH 32 routine

TARGETS CARIOGENIC BACTERIA

In children, M18 use was associated with a significant drop in S. mutans counts, one of the main bacteria linked to dental caries. That makes this a strong proof point for the microbiome-support layer of FRESH 32 Oral Probiotics.

  • Significant decrease in S. mutans
  • Supports a healthier oral bacterial balance
  • Relevant for cavity-risk management

DAILY USE MATTERS

The longer-duration gingivitis study suggests benefits build with continued use, but also may not last after stopping. That gives you a good retention-friendly message: consistency matters.

  • Benefits improved across 1-3 months
  • Not a one-off quick fix
  • Best framed as part of a routine
