Evidence ladder
We separate finished-product evidence from ingredient research, mechanistic research and general dental-health guidance. Stronger claims require stronger, more direct evidence.
1. Product-specific clinical trials
Most direct evidence for what a finished formula does at a defined dose and duration.
2. Ingredient / strain clinical studies
Useful for understanding an ingredient, but not automatically transferable to a different formulation or dose.
3. Systematic reviews / meta-analyses
Useful for seeing whether results are consistent across studies and populations.
4. Mechanistic & observational research
Helpful for biological plausibility and context, but weaker for proving a consumer-product outcome.

How we use references
- A source is linked only when it is relevant to the claim or evidence framework being discussed.
- Ingredient research is not presented as proof that the complete DentaBiome product has been clinically proven.
- Government sources are preferred for regulation, safety and standard dental-care guidance.
- Systematic reviews and higher-level evidence are preferred when discussing probiotics, xylitol and the oral microbiome.
- Conflicting or uncertain evidence is described as uncertain rather than converted into a stronger marketing claim.
Important evidence limitations
This site is an independent educational and affiliate resource, not a substitute for a dentist or other qualified healthcare professional. Persistent bleeding, pain, swelling, loose teeth, sores, dry mouth or bad breath should be evaluated appropriately rather than self-diagnosed from supplement marketing.
