First things first.
Post roll and stay quit, because you sound like a guy who will go right back to using if you get a clean bill of health. I know those types of guys because I'm one of them. Actually, I was the type who dipped as much as possible before a dentist appt so that if I was told to see an oral surgeon, I knew I would have to quit and wanted to "get it out of my system first." -------dumbass addict logic that allows you to continue using the drug you're addicted to.
You can't make an appointment at 10:30 at night, so post roll now. Call dentist first thing tomorrow. Most likely nothing abnormal, but might as well be overly cautious when talking about your face and ability to chew and swallow.
