In my experience I've known of two other cases having IDENTICAL presentation that were absolutely mercury-caused and were reversed overnight following root cannalled tooth removal, which is why that subject is the first thing I ask anyone I care about who is ill that asks my opinion. I attempted to pull a photo of one out of my magical box without any luck, but if one does an internet search for
mercury droopy face
the search results aren't barren.
For those who aren't aware, it is as though 1/2 of ones entire face to either the left or right of the nose, sags sufficiently to look appear as a theatrical mask.
Anyone who would administer or knowingly reasonably cause mercury or a mercury containing substance to be administered to Man, should be tried for an offense as a capital crime. Mercury administration to humans should be internationally banned in all forms.
