I had my wisdoms pulled about 3 or 4 years ago I think. My experience was great. Fast, easy, no anesthesia.
I opted out of being gassed, and chose local anesthetic. 30 minutes from the time I walked in the door, to the time I walked out. Healing took a while though.
None of my wisdoms were impacted, they were partially eruppted, and only 3 had grown. The reason I had them pulled were they were interfering with my bite, I have a slight overbite, but its still solid.
The teeth were cramped enough that the roots had fused together while they were developing. I'd occasionally get lock jaw where I couldn't open my jaw, and could barely get a straw past my teeth. The final straw was when I was eating a Chimichanga at a mexican joint at lunch and felt like I had bit down on a bit of bone. Well, it was bone, but it didn't come from the food. A chunk of the wisdom tooth had cracked of, because the tooth was basically dead.
I called around, set an appointment. I walked in, signed some paperwork, refused the gas 3 times. Got some novacain, waited 10 minutes. Dentist came in, open jaw, rams separator down the gumline, which made me make a pained noise. I wasn't expecting that. He shot me up again with MORE novacain. Then he walked away for 5 minutes. When he came back it was open mouth all the way, clamp goes in, close jaw halfway...CRANK/YANK, tooth out. Repeated 2 other times in the next MINUTE. Shoved some cotton gauze in there, and sent me on my way home with some anti-biotics and a few instructions to help prevent dry socket, and infections.
All together, it cost me $60 after insurance. I should have gotten it done YEARS ago. I kept the teeth as reminder to visit the dentist. One of them was dead and so rotten that I'm shocked it came out in once piece. Had it not, I might have had to go under so they could do surgery to remove the roots. They caused me problems for years, but I never considered the problems bad enough to get them pulled. I really wish I had done it earlier in my life.
