I had crown done following the root canal treatment on 14th tooth
3 years ago due to a regular recurring abscess. After the root canal treatment and crown, i used to get abscess at exactly the same location every now and then but that time with no pain. A month ago the abscess recurred again after a long while, so i went to a dentist (a different this time since i have moved places). He suggested that the previous root canal was not done properly and that the crown had to be removed.
