hi miriam : the information out there is overwhelming ,It would be much more simple if there were just one protocol ,but as so many of us have found out ,(that just aint so) it's not a one size fits all in this case ,for me I just decided to let my body do it's own detox at it's own speed however long that will take ? every time I tried to use any type of chelator ,even natural my body just couln't handle it ,so my body made it's own choice , I don't know where you are located but I am in northern michigan my dentist is on the (iaomt ) list of safe removal dentist he is very reasonable and I recommend him very highly I was charged $1800.00 for nine fillings I decided not to do the compadability testing but he can do that also,it's just another option
