I was k.o.'d totally for the extraction of mine in my 30s - they never came out - they lived way down in the gums, and one was at an angle. One of them kept trying to creep through, so the dentist said it was better if they came out. They left craters the size of the Kimberley Hole, which didn't close for a month. I had to keep swilling them with salty water and to ensure no 'debris' remained in them after food. I found the areas very sore and swollen for a couple of weeks, Luke, then things got a bit easier. I was left with a numb chin for about a year - it eventually wore off by tingling a lot for some months!
I know what you mean by the pulling, dragging and crunching - dreadful. I didn't experience that with the wisdoms as I was unconscious (thank God), but I did when I had two eye teeth yanked out at 14. The dentist actually had his foot braced against the chair, shook all over from the effort, and sweated profusely. By the time the second one was being hauled from its long, healthy root, the novocaine had worn off and I kinda gargled a request for some more. He then displayed his trophies to my mother and exclaimed, "If I'd known the roots were going to be this long, I'd have put her under!" Thanks, buster, now you tell me.
Keep swilling with slightly salty water, Luke, especially at night. It will help to close up the holes/swelling, and keep infection at bay - it's a pretty serious dental op, in fact, so you should expect to still have swelling and soreness for a bit longer. Sorry!
