Had a crown put in one year ago - it popped out. Moved recently, so went to new dentist to have crown cemented in. They took an xray after placing it in (not cementing) to view. They said there is a small margin and they cannot legally cement it in.  Called old doctor (500 miles away) - he said there was not a margin at the time he cemented it. The crown is not broken. The xray one year ago is taken from more of a top view, new xray is taken from side where you can see small margin. However, there is no decay on/in tooth under crown. Thoughts?
Hello Welcome to ChatDoctorSir I have gone through your query. Usually crown also have it shelve life but since it is only 1 year old then sometime it can be resisted if the condition of the tooth is good and crown has not become faulty. I will advise especially to visit a prosthodontist a dentist. Thank you
