i think u guys got the wrong impression about wisdom teeth. in my knowledge, all humans have 6 wisdom teeth, but only 2 pairs gotta be removed. if you ever have to get to take out 6 of them its probably pieces of the teeth that the dentist have to cut through because its too big or too deep rooted. if you are very sure that you have 6 wisdom teeth, i suggest going to an anthropology research department. they will be amazed.
