Your information is very helpful. I have not been sure whether to look for a periodontist, oral surgeon, ENT, or even a dermatologist. I will see if I can find an oral pathologist. I was not lucky to have the flare up happen around the holiday time. I did manage to see my general dentist because I thought the new flare up might be something other than OLP. The dentist did confirm that it was OLP which he thought might have been caused by trauma. I don’t remember biting my cheek but maybe I did in my sleep. Really appreciate your help.
