I had 8 wisdom teeth removed, all in a chair. One was hooked and I needed an extra needle - not bad going for four sessions in a chair! I don't even know if this guy is practising anymore, it's been years since I saw him last and he worked on the other side of town in Footscray (used to get me out of school for at least half a day when I had braces, but he was so worth it!).
Go the chair. Speaking as someone who not only had 8 wisdom teeth (practically unheard of and I had a dental journal come and take pics of one of the procedures that showed I had more behind the first lot!), but 6 of them were impacted - most people assume that would require surgery and GA, but I was much better off recovery-wise, for it
Ring around for a good one - worth saving up for, if you don't have insurance to cover it. Once it's done, you realise you'd pay good money for a job well-done.
