Trust me, that needle they stick in your gums is TOTALLY your friend. Do not fear it, infact if you can feel anything at all ask for more. Do not be afraid to ask for more. If you don't have enough anesthetic you'll regret not asking for more.
The first one I ever had pulled I made the mistake of not speaking up when I could still feel it. That bitch hurt terribly.
I've never had IV for a wisdom tooth extraction though.

For some reason they refuse to pull more than one at a time on me. All 4 of mine were impacted. Yours probably haven't erupted yet (that means they're probably still beneath your gums or maybe partially erupted, which means part of them is sticking out but most of them are still beneath your gums). Take my advice, if you can get all 4 out at one time DO IT! It really sucks to have to keep going back.
