Has anyone explored the possibility of tooth remineralization--that is the restoration of enamel and the natural healing of cavities? I first read about it a few months ago here: http://wellnessmama.com/3650/remineralize-teeth/ This article emphasizes diet changes the prevent cavities and restore tooth enamel, and also contains a remin toothpaste recipe that you can make at home. I was skeptical and I still am, but I started reading more about it, and it might be possible. I looked at some remineralizing toothpastes on Amazon and found one that had mostly positive reviews, with a substantial amount of reviewers claiming that it reversed their existing cavities, much to the shock of their dentists. (this is the product http://www.amazon.com/gp/product/B000I4C074/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 ) For 12 bucks, I ordered it. Why not, I don't have much to loose. Anyone have experience with this?
