I'm actually surprised to hear you got a wisdom tooth out in a chair popeyes mate, I thought it was always a surgical procedure.
Tripman given you have complicated wisdom teeth I don't think there's any doubt they'll recommend you to see an oral surgeon, who'll take them out under a general anaesthetic. I had all 4 of mine out that way a few years back. Honestly, it wasn't that scary. It was like any other operation in that the last thing I remember is being wheeled into the room, getting the anaesthetic, then waking up an hour or two later looking like a bulldog.
I was prescribed panadeine forte afterwards and though I played up my symptoms he told me pretty much point blank that you don't get anything stronger than that for a wisdom teeth extraction. It might be bullshit, I don't know, I don't think I've ever heard of anyone getting anything stronger than codeine afterwards though. I was probably lucky I even got that since I showed up for the operation high on smack, which was pretty stupid, and I felt like a naughty schoolgirl telling the surgeon about it before I went in (I was scared it might interact with the anaesthetic or something).
Personally, I don't think opiates are necessary for the pain of getting your wisdom teeth out.
