I had a root canal last year with Dr. Laundau. When I went back to him to tell him the pain was still there, he didn't believe me and said it could not be from that tooth. The pain was always there, day and night, and would wake me up at night. It caused my face to swell. I had the root canal redone and the endodontist told me there was old cotton in the tooth and some of the canals still had pieces of nerve in them (big pieces at that). This tooth would ache and bleed every once in a while. The endodonist I went to was shocked at how bad the root canal was and how poorly the canals were treated. If you had a root canal with this dentist and your tooth still hurts, go to another root canal expert and just pay to have your tooth pulled or done again.
