I have had two, but went to a specialist. My roots are curved and no dentist will even consider a root canal, but my treatment was wonderful and with the exception of the ice they rubbed over the tooth to find out which one was bothering me and the shot of novacain (SIC?), it was painless.
I'd rate having the root canal done right up there with giving birth - no lie!
I just don't like shots.
