So yesterday I had all 4 wisdom teeth removed.
I was simply amazed at how fast the dentist did it. It took him about 3 minutes to apply the anesthesia and then no more than 45 seconds yanking out each tooth. It was absolutely painless and I was out of there withing 6 minutes =o
Now.. I was spitting quite a bit of blood for the next 2 hours which I assume is completely normal, then took a nap, the numbness wore away and I woke up completely normal as if nothing had happened to me at all.
5 or 6 hours after "surgery" I was out at a soccer game with my friends, no puffy cheeks, no swelling, no nothing.
Amazing dentist if you ask me

So everyone who is getting it soon, there really is no reason to be afraid at all.
