One of my top teeth which has been filled some years ago has an abscess on the gum which has been there for at least 10 years. The tooth has no tooth underneath it so is redundant. The abscess gives me no pain, but may alter in size from time to time.
I recently changed dentists. My previous dentist was of the opinion that the abscess could be left as the tooth was redundant anyway. However my new dentist thinks I should have root treatment as the abscess could turn bad in some way (i cant remember the exact word he used). I had root canal work some years ago on an other tooth which didnt work & the pain was so unbearable it had too be extracted which was not a pleasent process.
Im tempted just to cancel the appointment & not bother with the root treatment.
