Random wibblings of an insane science fiction fan
I was pretty worried about my own root canal until I actually had it. Anesthetics have gotten so good these days.
This seems to be what the internet is telling me, too. Still not looking forward to it, though. It's not so much that I don't like pain -- although I really, really don't -- but just the general, extended unpleasantness of the experience. At least when I had my wisdom teeth out, I didn't need to be there for it. General anesthesia is great.
