I've been told fluoride varnish can work. However, I don't think this is covered in the fee schedule and it can be time consuming to have repeat patients come back for an application. So some dentists may be reluctant to do this when they can just tell the person to floss/brush better, and if it progresses to a larger lesion, then it's more money in the bank after a composite restoration.I mean when it's a " white spot". If no, than why not? How hard would it be to re-mineralize the surface?
The stock answer is usually once the demineralization has entered the dentin, however, in reality remineralization of lesions into dentin has occurred, it's just not as reliable as trying to remin enamel only lesionsAt what point is remineralization ineffective?
I once read a "blog" where someone was claiming to have remineralized a frank cavity of a tooth without fluoride; but, by improving their diet. Does this sound plausible?
