I have been reading on the internet that amalgam fillings are somehow bad for you, that they cause brain tumors and the like. I have several that have been good to me for the past 15 years, and you can understand I am quite worried. I spoke to my dentist on the phone, and he said that I should consider getting my amalgam fillings replaced with white fillings. I am not a dentist, and did not know what white fillings were so I looked it up on the internet. It turns out that white fillings have BPA in them which cause cancer. I am quite concerned and do not what to do. Must I really get cancer if I want to retain my teeth? Is it not better extracting them and getting a denture at this point?
