I had a root canal and crown from Dr. Durr on a back molar, and experienced great pain as no amount of anesthesia seemed to numb the area being drilled. Dr. Durr acted arrogant and annoyed, as if I were "making it up" that I could still feel the procedure. He left a gap between the crown and the molar behind it; maybe that was unavoidable but it's been worrisome and uncomfortable. I now floss constantly as a result, though, so that's good. In the end, he told me the entire root canal would probably have to be redone. So in addition to all the pain, the outcome wasn't good, although I'm thankful I haven't had to have the root canal redone yet. It was about three years ago.
