I had my mouthful of amalgams, most of which were under crowns,removed 3 years ago. I have been following a fairly natural detox program since. I use 2 naturopaths to assist.
From what I understand there is no real way to test how toxic you are. In my case I just went ahead because I had such a wide variety of symptoms. I am very glad I spent the money and I do feel much better.
It is important to use a dentist who uses the proper technique( rubber dams and air ventilators) so that you re-absorb as little as possible.
I would suggest getting a hair test done now. I think it will provide the best benchmark to compare with ones you do while detoxing. Plus it might give you and your ND ideas as to which supplements you need after amalgam removal.
It does seem to me that each of us have found a different and wide variety of detox programs.
I do wish I had done a hair test initially. I do one almost annually now.
Hope that helps.
