Hi, thanks for your post. Yes, mercury vapor is the worst. It can go straight in and up the nose, into the sinuses and anywhere it wants. For those of us weakened already and intolerant and sensitive, this can be enough to tip a person over the edge.

This dentist, who claims to have a clean office with his extraction system, isn't facing reality. This reaction was severe and it only took a few hours to begin.

Though most people might not notice anything, I am not one of those. I wish I was.
