I personally saved one of my own teeth from being root canaled or pulled. I had a tooth that was "drilled and filled" in my 20's, and ended up getting badly infected and abscessed many years later. I went to three different dentists, all of whom told me there was absolutely no way this tooth could survive, and it would have to be root canaled immediately, or pulled within the next 48 hours. I didn't know what the outcome would be, but I did know beyond a shadow of a doubt that there was a zero percent chance I would ever allow a root canal to be done on this tooth. 

The pain from the abscess was so excruciating, it was some of the worst physical pain I had ever felt. I knew I had to figure out how to fix this, but I was in so much pain that pulling the tooth was sounding like the only option. I finally found an amazing biological dentist who I trusted. I wanted his honest opinion on what he was seeing in my mouth, and what in his experience was the true prognosis. I explained my protocol to him in detail. Some of which he was familiar with. In fact, he told me his own wife had been using some similar components on their young daughter and had completely healed a fairly deep cavitation. But, with an adult tooth that has already been compromised due to "drill and fill" my prognosis definitely was not as good as his daughter's.

He was unfamiliar with the homeopathic components of my protocol, and a few of the nutritional ones (he wasn't plant based), but he told me that anything is possible, and that he had seen some incredible healing on teeth like this, but that there was just no way of knowing. He did warn me that I may end up going through excruciating pain again even after the abscess healed. 

I was willing to take that chance. 

He cleaned up the filling for me, completely removing the mercury and replacing it with the safest cutting edge modern fill material available. I put 100% effort into healing my tooth and the surrounding gum. It was a very challenging process in the beginning, because I couldn't chew anything on that tooth.

I used the same protocol I had been using on my children, but added a number of additional supplements and targeted homeopathics to do whatever I could to save this tooth from being pulled. And, it worked. That was several years ago, and in the most recent check-up, I decided to have a digital sensor x-ray, which has a 90% reduction in radiation dosage. I personally do not recommend any type of xray for anyone, unless absolutely critical to health, and the benefits outweigh the risks. In my case, I had to be certain that an infection or some sort of bone or tooth loss was not occurring under the surface of the filling, that could compromise my health down the road. So I underwent my radiation protective protocol before visiting my dentist, and continued with a radiation cleansing protocol afterwards, to give my body the best possible support I could to deal with the radiation.
