If the procedure is done by a competent surgeon, you'll be surprised how little pain there is post op. Others who see you soon after - friends, family etc, will take one look at you and assume you must be in agony. But in reality standard pain killers will be all you need. And maybe not even those. I can tell you I'd swap this toothache I've currently got for a couple thousand holes in my head every day of the week:D
