so, i'm going to put reading up on remineralization tactics off until i get the cleaning done and take a look at it. it seems clear to me that this isn't an available treatment, so i'll need to decide if i think i can wait for an unproven technology or if i should act now to save the tooth.
i still only see one clear cavity, although there are a few i'll need to clean to tell with. they're all root caries.
that means i should be back to what i was doing and hopefully get a post up tonight.
