I had a crown & a root canal done by Dr. James Lee in 2003. After two months of terrible pain, I called his office and they said that the pain was normal. I moved to Houston and after three years I could barely bite with the treated tooth. Another dentist suggested I go to an Endodontist since it wasn't normal that a tooth with a root canal was having those symptoms. My Endodontist said that the root canal was done incorrectly. I had infection in my tooth for over three year. The Endodontist had to drill through the crown and inject medicine to kill the infection and seal again. After the procedure, I had to have another crown done to cover my tooth. My insurance requested information about the procedure done by Dr. Lee since they only cover the replacement of crowns every 8 years. I called Dr Lee's office and they did not want to provide guarantee over his work or information about the treatment of my tooth. The person who answered the phone was very rude and hung up on me when I asked for her name. I feel like suing them for malpractice but due to the time involved in legal issues and the time constraint I have, I prefer paying again and be done with this issue. I am sharing my experience so it doesn't happen to anyone else.
