Go to my dentist, £300 and removed 12 mercury ones and replaced them with composites - fiddled the NHS so that it looked like I was just getting white fillings and not the removal, £1600 worth of work for £300 notes, and she used the dental dam, and tonnes of vacuums etc Necked tonnes of charcoal and collodial silver...never saw mercury on a hair test but didnt feel any better or worse afterwards.
