Not to scare you, but to be safe- From experience, please do not have any anesthesia (sedation) without there being an anesthesiologist present, they are experienced if anything goes wrong. Most oral surgeons can give anesthesia and rarely there is aproblem, but if a rare complication arises, do you want them managing it?
My 18 yr old just had 4 impacted wisdom teeth removed under "light anesthesia" by a very experienced oral surgeon. At the end of the procedure she wouldn't wake up (breathing fine), needed ambulance ride to hospital and eventually woke up. I've spoken to anesthesiologists i know and they think this is crazy. You want someone present who frequently handles emergencies just in case.
Valium, local, all fine without anesthesiologist. After procedure lots of ice, pain medication and don't use straws as you want the clot to form.
