About a decade ago I had 24 extractions and bone shaving for dentures (my teeth were going to die anyway, and I couldn't afford 24 root canals, and THEN getting dentures.)
I was not ABOUT to get dry sockets it was bad ENOUGH. I decided to avoid my mouth entirely but I also ah, really NEEDED to smoke. I decided on nasal smoking and the husband the engineer rigged me up a nose smoking drill that used the power of the drill turning somehow (I was a bit hazy on events) and it shot smoke straight up my nose, which I then inhaled into my mouth, and exhaled through my nose. I had to stick a lit cigarette in one end. etc.
Similarly when I had a ton of mouth surgery, I nasal vaped. Not in public and I was in no shape to GO anywhere either, so I just used a MTL device (my preferred device) and a very long SNIFFFF and inhaled into my lungs and out my nose.
It avoided the suction issue entirely and also did NOT introduce nicotine into my mouth, which is ALSO inadvisable for healing. Seriously, it worked great, the sinuses are great "absorbers" of nicotine and etc., it is not my PREFERRED way to vape by any means, but I will say, it worked.
You can try it if you have the inclination and not everyone does. Otherwise, I'd use a very wide open device where you barely have to inhale. You are still bathing your wound in nic so I'd say covering it with gauze pads and whatnot may be advisable.
I got a bit of dry nose but nothing major and (IMHO) it is the safest way to do it. As always, your mileage may vary and etc.
