My Best Man went into the local dental hospital (training section) during his lunch break from work, for 4 wisdom teeth removed. This was carried out TRAINEES, under a local anaesthetic!!!!
He went back to work straight afterwards. He complained of some pain but had no meds for it.
I have to say here that he has probably the highest pain threshold of anyone i've ever known but still, you hear horror stories too so I guess everyone is different.
Hope it goes well for you.
