I suspect it is variable from patient to patient (and possibly dentist to dentist). I had one removed a few years ago, and it was done in about ten minutes and left me with no discomfort post-surgery. OTOH, I have friends who've had ostensibly similar work done which took much longer, and they had some discomfort for a few days after the procedure.
