I had RCT for right side lower teeth 5. After one month, I started feeling extreme bad pain which was not fully going even after painkiller. I immediately visited dentist who said a rice size extra small teeth between teeth 4 and 5 is giving me the pain so he extracted that. Next day he released pressure of RCT tooth. It kept paining so today he removed crown and have appointment for tuesday that he will remove RCT material and leave tooth with medicine. Immediately after cap removal, I got a lump behind the teeth which kept increasing in size and right now it's a pea size. I need to understand the reason of this lump which came within last five hours immediately after crown removal. How it will be treated? Do I need to redo RCT or just pus drain or extraction or just antibiotics will help.

Hi lybrate-user, I can understand you had gone through a lot, but don't worry this infection is gonna subside. Mostly after root canal treatment a patient complains of pain due to two reasons either failed root canal or food impaction due to defective crown. The way you described the pain, I mean the intensity of pain suggests failed root canal, may be due to missed canal or due to improper sterilisation. This swelling is due to accumulation of pus, and most probably a gingival abcess due to some calculus or the cement with which the crown was fixed has gone in between the gums and teeth. Well xray would have given a clear picture, though I would say go for re-rct with a course of antibiotics. No need to drain the pus, swelling will subside after the course of antibiotic. Hope this helps.
