Hi. I'm sorry that I do not know the answers to your questions. I have one for you though. I have only one mercury filling in a tooth and was wandering if just that one filling is enough to make me sick. I have had candida infection long before my filling back in 1993 but hey whatever it takes. Is it expensive to get mercury fillings taken out? Did your dentist seem willing to do this? I would love to have it done if I can afford it. Good luck! Hope to hear from you soon.
