A few months ago, I had a root canal done on one of my canines. Everything went well, and it has really been bothering me. I can't get it capped until next year, when my insurance will pay for it. Anyway, I have my temporary filling fall out about every 3 weeks and I go back to get it filled everytime. My question is the last time it happened, I noticed that the tooth is starting to turn black. I meant to ask the dentist about this, but they are on vacation now, so I can't call them. I am worried that it is still decaying and will have to be pulled before I can get it capped which I would prefer to avoid at all costs. Is this something I should be worried about?
