If this yogi story is genuine why get your fillings replaced at all ? Simply take the herbs and live with the fillings! Alkalizing does the same thing it neutralizes the acidic nature of the mercury! If one has only a few fillings why pay the price and take the chance of having the mercury enter your blood stream full blast ! They say there are those dentist more adept at this procedure but can it be guarenteed and at what price a life of toxic mercury running through you vains ! I know those who still suffer years after having this procedure done and suffer from the same illness they did before ! Sometimes it is better to let sleeping dogs lie !
