Had mine out in March, all 4 fully impacted, and I was nervous, too...and I work for a dental insurance company!!! Our training was such that I knew every last horrific detail...and I somehow got through it. The IV is scary, I'll admit, but is standard, and the oral surgeon has to be certified to do it... and I also have to admit that I did not have a good oral surgical experience...but now that all is said and done with, I have to say that the alternative was worse. My wisdom teeth roots were entangled with the nerve roots running through my jawline, and kept getting infected. They also got infected after surgery, mainly due to the irritation of the nerve when the teeth were pulled. It was a month long story from Hades, and while I would never elect to do it again, I'm glad it's done. With fully impacted wisdom teeth, you just have to grit your teeth and bear it. There really is no other way, and as scary as it may be, the long term effects are so much worse. So keep a stiff upper lip and go for it. #1 what choice? and #2 in the end, it's worth it.
Good luck!!
