Can titanium implants cause auto-immune problems, wondered one reader. One reader tells us that she developed ME and was infertile after she had a large amalgam filling fitted with titanium rods. She improved after she had all amalgam fillings removed, and started a detox programme. Kinesiology helped determine the things to avoid. But another reader is faring well with his titanium plates, which were screwed to his jawbone. So far, so good.
