I had never read that until yesterday either. The Biological dentist is sending me (and my husband) to have a dental materials compatibility test of some sort next week- it's supposed to show the amount of mercury and other metals being emitted, to know which ones are the highest priority to deal with first. Now I'm more concerned too for the uranium/polonium in the mouth too.
What Hulda is talking about for more clean-up, sounds awful (and expensive).
From what I learned from Newport's posts..uranium can't be detoxed if fluoride is a problem. So, fluoride detox would have to also be done so uranium can be eliminated.
Read through Newport's blog posts, for frequencies for specific parasites etc, and read the definitions at the top. Many of them have a warning about the toxic metals that will be dumped with the parasites being killed. //www.curezone.org/blogs/f.asp?f=2109
