Prebiotics & Oral Health
A plain-English guide to prebiotics, oral ecology and why ingredient-level evidence should not be confused with product proof.
Prebiotics are substrates intended to be used selectively by microorganisms. In oral-health discussions, the useful question is not simply whether an ingredient is called a prebiotic, but what evidence exists for the specific substance and context.
