My wife is 54 and recently had a cracked tooth a while back and the dentist did a root canal. The tooth continued to bother her for weeks. He did a root canal and it continued to bother her constantly so much she could not chew on one side. Then started to do a crown after; putting in a post the tooth continued to cause her constant pain. Now she is tossed between having the tooth pulled as opposed to having it crowned. She also suffered a stroke several years ago and is on Aspirin if that makes any difference. Is pulling and leaving a gap not advisable?
