Reading a few stories above I'll add mine. When I had a couple out a few years back it was pretty grim- one was impacted and had kind of fused into the jawbone. They had to drill away into my jaw for about 30 mins to get the damn thing out. The other came out no bother though. Thank god for painkillers, it was tuily surreal to smell the heat as they drilled my jaw bone and watch my blood scoot through the suction tube.
I thought I'd go back to work the next day as I felt great, but as soon as the painkiller wore off I knew I'd have to take a couple of days off. My jaw had definitely been pretty brutalised.
It was sore for days and then achey for ages. Especially if the weather was about to turn nasty. I felt a bit like one of the old folk who tell you it's going to rain because their knee aches!
Thankfully, it settled down in time and I can't tell when the weather's changing these days.
