Last tooth I had out took two dentists and over an hour to get out. The both looked at it and decided it had a spiral root. Maybe they should have tried unscrewing it instead of tugging.
Well, I don't know whether you'll believe this, I didn't at first, but apparently I was in the operating theatre for FOUR hours when they took all my wisdom teeth out many years ago, the dental surgeon who was assisting said that they had a terrible time trying to get the little buggers out and that it was no wonder that I was having acute pain afterwards. I had to have a fortnight off work the pain was so bad and as for the infection afterwards, there was a 5 mile exclusion zone around my mouth!!!!
