"The intraoral examination demonstrated a significant biting line bilaterally into the buccal mucosa."
I do. Heh heh, sorry to be a know-it-all, but I have this too, it's a line that goes across the middle part of your inner cheeks, that matches your teeth line -- I don't think I chew on it subconsciously but when I clench my jaw I may be constantly sucking moisture out of my cheeks (and by association, my inner lips).
What led you guys to try this in the first place? Doctor's prescription?
