Hi there, I've got to have 2 new fillings at the dentist next week and I'm due to have amalgam fillings but now I'm really worrying about the potentially negative health effects of having these types of fillings. I've already got 4 of them in my mouth which I've had for nearly 2 decades so am now considering having them all replaced with white plastic fillings as I've read some truly terrifying things about the long term health effects of amalgam fillings. Does anyone know anything about whether I should or shouldn't get amalgam fillings and have the ones I do have at the moment replaced??
