I have had 3 root canals and I am dentalphobia. I would reccommend that you go to an endodontist if possible. All they do is root canals and they are very good at it. One time I allowed my regular dentist to work on a root canal - he flubbed it and I ended up in the endodonist's chair as an emergency with one side of my face hugely swollen. If was as if I had had to have two root canals.
