Hi lawstudent. I feel like I'm getting much more versed at the amalgam issue but really lacked knowledge on root canals and other issues. In fact I'm just ordering Hal Huggins book now. Sad, I know. In many ways I am heart broken that my wife wants a root canal. Her health is so important to me, and I just can't convey to her in the right way the importance of understanding the issues of root canals. I'm hoping I can read some of Hal's book to her and hopefully get her attention on these issues. She has free agency and all I can do is continue to suggest removal. What to do.....What to do....? It's good to hear that the ozone treatment has gone well for you. I asked the dentist concerning the cause of the crack and was told that she had to go down a little further because the amalgam was leaking into her tooth!!!!! Wow, that was frightening! So I guess the added depth got to the pulp. Oh how I wished things would have gone smoothly. I got her to get her amalgams out and now she is in process of a root canal. I am so desperate to help her regain her health but this has been a serious setback. According to some here on this board, root canals can pose a greater danger than amalgams! This part of our journey just got much more complicated.
