I had this root canal about a year ago and when this new dentist looked at it he said that guy did a lousy job. He left a big hole in the tooth and that is why it has bothered me ever since it was done. I don't know if I can come back on him since it was a while back but I sure would like to do it. The other thing he charged he twice what this dentist is charging for the same thing. Dentist and teeth suck big time.
