I had all my fillings redone and had a choice of pulling the root canal teeth or refilling them. I refilled them.
Did not want to have implants or a partial. Read Huggins book and it did not proof to me that I should have them pulled. The people in the book who felt better had done many things to improve their health and I did not feel desperate. After the work I had done I still felt the same. I would do a root canal again and use herbs or ozone
as prevention and of course would not get a mercury filling.
