i am looking for info about mercury fillings

hello! i am on my second kidney cleanse (10 day master cleanse) leading into a liver cleanse. both times i have
gone into this cleanse i have read about the importance of getting the mercury removed from your teeth. i have
read that it still leeches into the system in its solid state. with this small amount of info and the desire to get the
toxins out of my body, i spoke with my dentist. he rejected the idea that mercury fillings are poisonous (imagine
that) and went on to say that the entire scare was started by a dentist in colorado who has since lost his license.
he did say he would do it for me, but i would like to present him with some solid facts on the matter. if anyone
could help it would be greatly appreciated. thank you.
