Oral probiotics are live bacteria in a lozenge or a chewable tablet. Do they work? It depends what for.
For bad breath, a 2025 review pooled ten trials: the sulphur gases behind the smell dropped significantly, but the possible range runs from a large effect to almost none. For cavities in children and teenagers, 19 trials and about 2,600 people: no effect. The breath review itself warns about small trials and publication bias.
The format matters: a lozenge stays in the mouth, a swallowed capsule goes straight past it. And in the trials they did best added to normal cleaning, never instead of it. Bleeding gums, or breath that is bad all day, is a dentist first.
