It's pathetic but I can't remember exact details......I *think* I had 3 out...2 on the bottom, one on top. I also had a crown done. I think the one on top was impacted.

I was completely scared to death also, but it turned out not nearly as bad as I had imagined! I wasn't even put out, just had a bit of that lovely gas hehe. It was hurt and swollen for a few days, but healed quite soon! Good luck!
