I like this:
"However, we need sedation to make that tolerable for the patient'.

and this:
"3. Using charcoal serves no good purpose either, as it will not adsorb mercury vapour once it gets wet."

sounds evil to me. First he sedates you so you will not ever know how much mercury got washed down your drain, umm I mean throat or what else went on... and then he wants me to believe that the purpose of the charcoal is to absorb mercury vapor as though only mercury vapor is the problem. Was he intending to stick the charcoal in your nose? No wonder they need sedation. Tell me please, what exactly happens to the mercury vapor after IT gets wet?

I really like this:
"5. Removing amalgam in stages will only result in mercury vapour coming out of the amalgam that has not been removed only to hidre under the white fillings that were placed. All amalgam must be removed at once in order to prevent this from happening."

... he sounds very concerned about mercury vapor 'hiding' under your new fillings... but he doesn't give a hoot about it hiding under your tongue or in your nose or down your throat..

I think you should avoid this so-called dentist because he gave you his answer right there... mercury will be hiding all over your mouth as you are sadly sedated in his office chair.

quack quack quack.

Arab Andalucian scientist ibn sinna, you must be kidding, did someone post that as a joke?
