I've had two root canals done with local anesthetic and no real problems. I was real nervous for the first one and went to a specialist and they used a lot of local anesthetic that I couldn't feel anything but a little pressure. But the second time I just had my doctor do it with his anesthetic, and it wasn't much worse than a filling for me. A little unpleasant but not unbearable. On the negative side, either that or some other dental work I had done close to the same time must have damaged a nerve and now I haven't been able to really taste anything in the front half of my tongue the past three years (still can on the back of my tongue, at least, thankfully).
