I had a root canal done on one of my back molars. The root canal was done about two months ago. I was to go back in for the crown so I only had a temp crown on. That came off a month latter. Since my appointment to go back was next month I did nothing about it. Now when I was eating something part of tooth with the root canal broke off. Now I have a hole in my tooth. My appoint is in three more days. The dentist was going to put the new crown on. What will he do now? Will I still get my crown?
