7-8 years ago I had a root canal done by a DDS. Last week my new dentist referred me to an endodontist because she felt that that tooth was having complications. The specialist found a file in the root canal along with what he called, "Significant infection." The endodonist couldn't extract the file so I have to go in for oral surgery to have it removed. The original dentist NEVER informed me of the broken file or that it could cause complications. I'm not a "sue happy" kind of person and I don't want anything that isn't coming to me; however, is it unreasonable to ask the dentist to help me cover my medical expenses to have this corrected? Thank you for your time.
