During eventual amalgam removal, the dentist could, hopefully, substantially reduce your exposure to
/ absorption of mercury further, compared to standard procedure (water-cooling and high volume suction), by;

* Putting a rather big transparent plastic bag over your head / shoulders with overpressured fresh air blown into it. In front of the mouth the plastic bag should be reinforced with cofferdam and pressed into the mouth. This way the only thing exposed to the amalgam powder / mercury vapour is the tooth the dentist is working on.
