18 fillings in mexico Feb.2004,cost 2200,some dentists there will do same for 1700.no documents on composition, 1 wisdom tooth lost, filling was too deep due to previous mercury dentist, 1 filling fell out and had to be capped.good fit otherwise. steady improvement in mental health, i dont know how easy it is to get ceramic fillings (cast and glued like gold) in mexico. They may be the best due to having no electrical properties and no composite chemicals, however I still think there is no way to tell the difference between the three types in how they will affect you. I dont believe that clifford test method is scientifically proven. ANd I dont know if there is any validity to the meridian theory in regard to gold fillings and negative effects. Still the best thing I ever did for my health.
