I just wanted to post quickly about the root canal issue. My lower back molar was root-canaled about 2 years ago, before I was aware of the health issues related to root canals (or mercury). I recently decided to have it re-treated rather than extracted because I am already down 4 teeth and 4 wisdom teeth (all pulled for orthodontia years ago because I have a really small mouth) and removing that tooth effectively removes my ability to chew on that side.

I struggled with the decision to pull or retreat, but I figured I would take the chance on it and I can always pull it later if necessary.

My retreatment involved getting the root canal re-treated. The endodontist used a product called bio-pure to cleanse the inside. The materials available now are supposed to be better than even 2 years ago. However, I also had the tooth treated with ozone. Interestingly, that caused a severe ache for several days as well as a headache. I believe it was killing of some of the bacteria that the bio-pure didn't touch. I will have a second ozone treatment this week and then get it sealed up. My dentist said that they will be able to test at the gums for bacteria in the future to gauge how the tooth is doing. Note that my original root canal never "hurt" me, but I believe it was very toxic, especially after the post-ozone reaction. I wouldn't use pain as a gauge of how toxic the tooth is to your body.
