It is possible to detox mercury with gold crowns. I am doing it although it may be slower than without them. I had my last mercury fillings out last January and have been slowly detoxing and feeling better. I have had great luck with the algin Russ talks about. It accelerated the detox and minimized the side effects. I have gold crowns with no palladium on most of my teeth. Before I replaced the crowns I did have a dental materials compatibility test. I have had some pretty good improvement with increased energy and mental shapness and decreased anxiety and some improvement with fibromyalgia symptoms. I am hoping to get better as the months pass.
I think no matter what if you are heavily mercury contaminated it may take months to a few years to detoxify. It is better to do it slowly. Cetain vitamins and supplements can help. Goodluck!!
