Wisdom teeth removal: did they put you under or just numb you?

If they put you under: how much did it hurt when you woke up? How long after the procedure?

If they just numbed you: how much did it hurt during and after? How long after did it hurt?

Apparently my dentist doesn't have the resources to put me under to remove my wisdom teeth, so they're just going to numb me. They said I could pay $50 more to get gas to "take the edge off".
