Chucks	Hello. I've been a little confused recently because I went to a new dentist and after x-rays, the dentist mentioned that I should have a crown done on my root canal. This was actually a little surprising because my previous dentist had not mentioned about needing a crown. I had a root canal done on one of my premolars more than 6 years ago probably by a specialist. I remember having to return a few times in a course of 2 years I think to get it done. I decided to ask my previous dentist about this and he mentioned that since my root canal was not done because I had a cavity, I do not require a crown. I remember my gums started to swell up below the tooth and hurt and that's how I found out I needed a root canal done. I know that people normally do get crowns done after their root canals. I haven't had any problems with it at all for the last 6 years. Am I just lucky that it hasn't cracked yet and should I get a crown done? I would greatly appreciate your opinions on this. Thanks!
