the claim

Flossing prevents cavities.

the verdict
CONTESTED PARTIAL
Recorded sources
3 sources for · 4 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that flossing prevents cavities?

Partly. Popular self-help and a government tip assert flossing prevents cavities, while systematic reviews and Cochrane-based summaries report no high-quality evidence that self-flossing reduces caries, with only limited professional-flossing findings in children. The evidence is mixed and partial on both sides.
