I don't think it's too big of a deal. I mean they let you eat pretty much like a half hour after and that's exposure to any number of different attacks. While smoking isn't that bad for your teeth it's not great but I wouldn't worry. Smoking after you get teeth pulled like your wisdom teeth is another story, however, due to the negative pressure building up in your mouth as you pull and the possibility of dry sockets which are nasty painful; then again I smoked the day I had mine pulled and lived to tell.

Stay high
