I’ve had one of them out (warning: contains graphic images of an extracted tooth).
It really wasn’t painful – the most uncomfortable thing was the injection in the palatal side of the gum, and I heard a noise not dissimilar to the squeezing of a cork in a wine bottle as it came out. One suture – I think – and a bite down on some gauze for a bit, and I’m fine.
I am still a little high on the lidocaine, but that will pass.
If you’re worried about having a wisdom tooth extracted – don’t be. The worst bit is the anticipation!
