As a senior citizen I am embarrised about my poor dental care and the fact that I have a mitral valve that stayed wide open about 15 years ago. So far everything is fine. I do worry about the relationship between poor dential care and how it can cause problems with the heart. If I would have an opening somewhere in the heart or a valve it could cause serious problems. All this relates to the fact that I had a bad experience with all the staff including the dentist about 8 years ago. I had three root canals done, one cap stayed on even though it was never at the right level. Ten days after my root canal I could not chew a soft shrimp because I had pain from the root area. Pain like a cavity/nerve pain. The staff told me I was immagining the pain because the root was removed and would not let me talk to the dentist. This dentist had dental students doing most of the dental work. The dentist never came back into the room to check the work that was done by the student. I have never been back to a dentist again. My biggest concern is heart problems in the future.
