I read the OP, and no more.... so, here is my take:   
I had all 4 of mine removed at once.  My Dad drove me to the Doc.  I waited about 15 mins after I arrived.  I went back, and within a few mins, was put under w/ General.  15 mins later (LITERALLY) I was being awaken by the nurse.  All 4 were chompers were gone! About 10 mins later, my Dad was taking me home.   
I had no issues, and am glad it was done, when it was.
