Fuck, I once went to a different mercury-free dentist that happened to be a woman. Total crap, from start to finish. They fucked up the x-rays so had to retake the mouth. They fucked up the filling. The whole time they were shooting the breeze and I had no confidence. Went back to my old dentist (male) and he was asking what the hell I had done. Should have stuck with him. NEVER was I ever worried or uneasy with him, since childhood. An artisan. Sadly he died several years ago. Should have had more of the needed work done with him while he was alive.
