Draft for the clinicians’ review

This material is research-led and has not yet been checked by an oral health clinician. Nothing below is known to be wrong.

The one claim here has been confirmed:

H1The reversible / irreversible threshold. "A surface that has softened can re-harden. A hole cannot."Confirmed by the clinicians on 7 September 2026: Asked whether to say reversible or something else, the clinicians answered "Reversible." The threshold ships as written and is not to be sharpened.
