Well, let us know how it goes, the remineralization. It's my understanding that enamel can't be re-grown, but that you can fill in the cavities with secondary dentin.
Keep the saliva pH alkaline...
Search the OP forum "remineralization", there's good info there. Also, do you OP? Good way to cleanse the teeth of nasties... :)
How the heck do you get rid of the calcifications, is my next Q... ??
