Thanks Lisa! That's what I was hoping someone would say. ---------- > Here's a question: in a situation like mine, would a minor cavity > heal itself, or is any degradation of the enamel permanent? Small cavities can be reversed through good oral hygiene. Enamel can indeed grow back from a small degradation. A good dentist will not fill every cavity as soon as it shows up on an x-ray. I haven't had a new cavity that needed to be filled in almost 20 years. Lisa Sporleder Ester, Alaska
