About Decay Guide

Decay Guide covers the slow, ordinary processes that decide whether teeth last: how a cavity forms, how gum disease progresses, what erodes enamel, and which parts of that are reversible.

We are not a dental practice and we do not treat patients. Nothing here is a diagnosis or advice about your own teeth.

Most dental content is either marketing or scare copy. We try to be neither — where the evidence is mixed or the numbers vary widely between studies, we say so.
