i had mine out at 19 and it hurt like a bastard. i couldnt eat solid food for about a week, had to keep gauze in my mouth to soak up blood, tasted like crap for 3 days and had that taste in my mouth for another week. bothered me quite a bit for a couple weeks, then it was fine.
dentist told me not to smoke for a few days because the suction could open the stitches, but i toked some reefer the next day, gently, and was alright.
