I am having 3 wisdom teeth pulled out how long is the procedure?

It varies: It depends on the situation . I.E the degree of impaction if the teeth are impacted and so on.. There is no specific time really sit for the procedure it could be half hour . It could be more . It depends.

It depends: It depends on many factors: are the teeth fully erupted, with nice straight roots, or do you have long skinny irregularly shaped roots with curves and bends in the roots, ; are they bony impacted, partially bony impacted; have they had previous root canal treatment? You should ask the dentist who's removing the teeth the time needed for the procedure.
