the tops are usually just as simple as any tooth gettin pulled,its the bottoms that are the fuckers and usually need hospital to do it
i got my top left out 2 year back and was fairly easy,but u do get a bit of pain for a couple of days around the jaw and ear area,like a dull earache
just make sure infection is away before it gets pulled or youll be jumping out your seat,dentist shouldnt pull it till infection has cleared anyway
