I had the two bottom ones out at once in the hospital under local (my choice), they were impacted, totally sideways.
I am a relaxed, confident patient, not squeamish or scared of dentist, but it was bloody awful. They had to cut the teeth into bits to get them out. Worst bit was the joint pain in my jaw / head (up by eyes) from jaw being stretched for so long, lasted for a whole week, agony, would probably have been quicker and hence less pain under general.
It was way, way worse than 2 C-sections with complications!
My face was mega swollen too.
Worst bit was, the dentist was really attractive, I was single at the time and trying to look appealing, my mum was with me and was filled with mirth at the sight of me trying to flirt while still numb, had massive hamster cheeks, no neck, drool and blood and bits of tooth dribbling from both sides of mouth!
