Hi, I had all 16 large amalgum fillings removed over 4 years ago in the procedure with rubber dams to prevent reabsorbtion of mercury. The amalgum fillings were replaced with white composite fillings which broke down after 2 years. The dentist said my bite was too strong for them. These have now been replaced with gold inlays, which are not ideal. I can't say that it has made any difference to my general health. Love and Light, Deotima.
