I had mine done two-at-a-time.
The dentist suggested that, but I'd rather deal with that only once. The trick is paying for it and finding a good time to do it. Actually, this semester might be a good time to do it. The oral surgeon at the office I use only comes on Wednesday a month. I would have to get a sub for my Wed. night class and I might take Friday off too. I get one paid sick day per section per semester (and I'm lucky I even get that much) so that would use up both my sick days. I wouldn't be able to get sick again for the rest of the semester, but I could have Thurs-Sun to recover without worrying about work (I already have Thurs off.)
But then there's still the payment to consider...
