I have used Dr. Feder for procedures that my regular Dental Clinic would not do and emergencies. This included tooth extraction and emergency filling replacement. He was very professional.
I just had two root canals that are in process. I have residual pain in one, although that may be from an adjacent tooth that had a root canal a long time ago. I am looking for a endodontic specialist as a second opinion and to explore a Calcium Oxide or Calcium Hydroxide procedure. I recommend people to go to an endodontic specialist for root canals. One tooth extracted was from a tooth that had a root canal from a generalist.
