Smoking im not sure, but I know even when sneezing a week later the pressure in my mouth definitely irritated my gums.
Drinking however...I was at the bar 4 days later. The whole antibiotic/alcohol thing comes into play, as well as alcohol drying out your gums/possibly affecting stitches
I'm an idiot but I got away clean. Hey, Dead Guy was on tap down the street, what was I gonna do? SAY NO?!
