I just had a root canal with Dr. Grosko. I was pretty nervous going in, as you hear so many horror stories... I'd rather keep putting it off. Like the old saying "worse than a root canal". I kept waiting for the pain, but it never came. It was a more intense procedure than a regular filling, but honestly did not even hurt as bad. So I guess the saying is outdated. Never again will I be nervous about a root canal. Piece of cake!
