Q. Hi,. I got fixed a crown by a dentist for my front teeth 3 years back and for the past two or three days I am feeling sensitive to cold and I can feel whatever I ingest that it feels like it goes inside the crown and I just checked if it is loose but it is not, I am really scared, how will the doctor remove the old one it is so strong and hard inside and by removing it does my teeth get loosened, lots of things going on my mind terribly scared as I am not yet married, I got this done for asthetic purpose now that feeling did a wrong thing. Please I need to know from you that what should be done? right now having a all ceramic crown, does it need to be x-rayed, removed and cleaned, need your sincere advise regarding this. Regards
