Kind: research · Impact: low

## In brief

- A ScienceAlert article reports that the number of teeth a person has is linked to dementia risk.
- The article describes tooth count as a much greater risk factor than previously realized.
- The provided source is a short teaser, so the study's design, sample and effect size are not available here.

## Why it matters

If tooth count is a genuine risk marker for dementia, it could give dentists and clinicians a cheap, visible signal to consider alongside other known risk factors. The source alone does not establish how strong or causal the link is.
