I'm 27 years old and just yesterday I went in for an extraction of a wisdom tooth in my lower jaw. I was terrified, really I was, especially once I got in the chair and the surgeon told me the tooth did have to be removed. (It was causing me pain cause it was trying to come out but was stuck halfway under bone.) But three shots and less then five minutes later, the tooth was out, and I didn't have to have any bone removal or drilling.
Today it still hurts a little, but the bleeding has stopped and I can move my jaw pretty well.
All in all, as long as you go to the RIGHT person, you shouldn't be worried about dental procedures. Believe me, I'm pretty nervous even about fillings...not too long ago I had to have a root canal and the endodontist was such an expert that I was actually falling asleep in the chair while he was doing the procedure. After the numbness wore off I had NO pain with that root canal.
An extraction creates more trauma to the jaw, but the less they have to do to get the tooth out, the better. Post-operatively, it is imperative one follows all advice and takes the antibiotic. Not doing so is why I think so many people suffer with dry sockets or infection, because either they don't take the medicine properly or try to eat solids too quickly. Just force yourself to do everything in the instruction booklet the oral surgeon gives you and take extra special care of your wound. (Remember that your body has just suffered an immense amount of trauma to the jaw...after all a tooth has been YANKED OUT. The severity varies, but I think some people take it too lightly and that's why they suffer for it.)
Eating is very important too, even if all you can get down is liquids, try to drink juices with vitamins or eat yogurt, jello, oatmeal, etc. This keeps the nutrition coming so you can HEAL FASTER. Even if when you eat you experience some pain, just deal with it. You'll be glad you did when you realize that only a few days later the tooth extraction site doesn't hurt anymore and is doing well because you ate properly. (And drink lots of water, bleeding can cause dehydration and make you feel lousy.)
This is all my personal advice and I'm no doctor, so be sure if you have any concerns to speak with your doctor before doing anything. But I hope I can be of some service with this advice.
