From what I heard EDTA cannot be taken orally, as the absorption rate is only 5% and it is very damaging to the gut. I could not find any more specific recommendations from Cutler on EDTA administration, and practitioners who offer EDTA detox have such idiotic statements on their websites regarding other chelators they give you no reason to trust them with a needle.
When the level of toxicity goes down and the liver and kidneys improve, the body begins to remove some of the other stuff (such as aluminium from the brain, I believe), on its own. Not sure if this is the case for cadmium, too.
Also of course be really really sure there isn't an Amalgam lurking
under a crown or otherwise hidden somewhere.

Prime suspects are teeth that had both Amalgams (removed) and root canals. Many root canals are sealed with Amalgam that is so deep inside microscopic tubules of the tooth that it readily leaks into the bloodstream, and cannot be removed without removing the entire (dead) tooth.
