He redrilled all my resin fillings and replaced them with mercury, gee, thanks a lot for the poisoning!! As toxic as amalgams are they suppose to be long lasting, but not after his "magic touch!" An ugly crown he put on my molar failed in 3 years. He said my tooth was too small for a normal crown and it was impossible to put porcelain on top of it, which miraculously next dentist proved wrong... Utterly incompetent!
