If they pull the teeth all at once they'll probably put you asleep for the procedure, if you have a good dentist and surgeon they'll suggest it anyhow.
Beause your mouth is so small the procedure is quite invasive hence the full narcoses.
I won't lie to you for me it hurt like hell, and I still feel the pain in my face (I had them pulled in may) make sure you find a competent surgeon.
Pulling wisdomteeth is somewhat a standard procedure and most surgeons do this 10 times a day (so to speak)
If they tell you you need to have them pulled, coz' this adds to the stress and pain on your jaw, just have them pulled.
Remember, you only have to get rid of them once in your whole life.
