Yes, I had two root canals done that failed. It was shortly after that my TN came out in full force.The dragon was released. But, if I look back as to why I went to the dentist is cause I was having pain. I had a ct done of my head and sinuses that came out clear. So I went to dentist as next stop. If you read all the above sticky's and get the book stricking back from the TNA in fla, they talk a lot about dental work. http://www.tna-support.org/ Good luck and don't be afraid to ask ?'s Jen
