And you thought I was going to say ASS, well I wasn't I was going to say gum. I recently needed to have an old root canal redone. It had developed an abscess at the top of the canal that needed to be removed. I wouldn't recommend anyone having this done. It's very painful as they can't go through the tooth once it has a crown on it. Rather they cut through the gum. It's NOT FUN. Watch at your own risk.! This video isn't for the faint of heart as I don't look good nor is the inside of my mouth a good look.
