I had my wisdom teeth removed at 15. They kept moving up and down and there was a lot of conversation about whether or not to have them removed. Eventually, they were taken out when I had another tooth removed that had become embedded in the roof of my mouth and had never moved down (I had a milk tooth until I was 30 and then had it replaced because it was so small compared to my other teeth).
The operation was really no big deal. I could've had it all done under a local anaesthetic but I chose not to because I didn't like the idea of watching all these people come at me with implements (my 15 year old female imagination ran wild!), so I had it done under a general anaesthetic. The only downside was I threw up a couple of hours after 'coming to' as a reaction to the anaesthetic (same happened after the birth epidurals which is not part of the 'bonding picture' I'd ever been told about
), but otherwise, no problems at all.
