I have a genetic disposition to canker sores and get them quite frequently which as you can imagine is miserable as a pipe smoker. I still have my wisdom teeth and will often get them in the back as I assume I might bit my cheek with my wisdom teeth in my sleep (sorry for the tmi). I have always read that one should entirely abstain from pipe smoking to let sores or lesions in the mouth heal but are there really any impacts of occasionally (mostly social) smoking with a sore in the mouth. If @Doctor Chopper has any insight, I would love to hear. Blessings all.
