## TL;DR

Dentists see the mouth more than any doctor. A standard, recorded oral cancer examination with a referral route would catch cancers earlier at almost no cost.

## Summary

Dentists see the mouth more than any doctor, so this idea mandates a coded, recorded two-minute oral mucosal examination at every dental check for adults aged 40 and over, with photo documentation and a referral pathway. Oral and oropharyngeal cancers are rising with HPV and often present late despite being visible; dentists already examine inconsistently, and coding plus a pathway create accountability and data. The aim is to shift oral cancer diagnosis towards stage I-II at almost no cost. The test is a regional stepped-wedge rollout with registry linkage. Speculative in maturity, it addresses the bottlenecks The hardest cancers are found late and Prevention we already have is not deployed.

## Fields

- Kind: Idea
- Last checked: 2026-09-08
- Hypothesis: Mandated recorded oral examinations increase stage I-II oral cancer diagnosis by at least 10 percentage points within five years.
- Rationale: Dentists already do it inconsistently; coding and a pathway create accountability and data.
- Proposed test: Run a regional stepped-wedge rollout with registry linkage.
- Maturity: speculative
- Actor: policy
