Don't wear a T shirt that shows up sweat as after 30 minutes of wisdom tooth wrestling the pain will be overtaken by embarrassment of the rather fetching arm pit emissions.
I had all 4 done under a general, as my jawbone had to be broken to get the botom ones out.
My mum took one look at the x-rays and said "I'm not touching them with a barge pole, you'll be going to a GA clinic. It took them about an hour to do it and I felt like shite afterwards, but it would have been much MUCH worse under a local.
Having to eat mashed food afterwards was a bummer though - as was looking like I'd done 9 rounds with Lennox Lewis
Broken? Seems a bit extreme, my upper ones were a bugger but they drilled the bone and then split the tooth as I said before. Sod having my jaw broken, I think I'd have kept the teeth.
