My last tooth extraction I was told not to suck on the socket, basically suck the blood out etc because you can get something called dry socket, its important a nice clot forms inside. Of course, vaping kind of replicates sucking when you're drawing in vaper.
Long story short, I waited for about 45-minutes after leaving, left the gauze in place, kept the wattage at a sensible level and took little puffs. I was fine, no issues, no drama, by that evening the gauze was out and I was still vaping. I've also had several extractions when still smoking cigarettes and basically smoked straight after.
I'm not saying you should repeat what I've done but with a little common sense and being conscious of the tooth just ripped out of your mouth and vaping sensibly I survived these extractions very easily.
