So what if it does? The chelator binds it, so no harm is done and your mercury burden is still lessened. If it's close enough to the surface to be bound by the chelator either through the bloodstream (eg; gum tissue, ligament) or saliva chances are excellent it's going to release the next time you brush your teeth or eat something anyway I would think. So why not bind it with the chelators? If it's not bound and eliminated it sails away and does damage where ever it lands. Then you have to chelate harder later to release it, plus heal from it.

I have 10 amalgams still in my mouth and would end up curled on this couch within a week if I stopped chelating. I actually almost feel better (almost, not quite) now than I did before the mercury poisoning incident. prior to that I attributed some minor aches and pains simply to aging. For sure my head feels better. I do need to start working out again to regain my muscle strength though. Though I have been doing a lot of digging in the garden heh. My organic cilantro will be ready soon. Amazing, mostly volunteers from last year, they sprouted in the snow all by themselves and leven later snow did not deter them... such a blessing.
