YES: Frictional keratosis is a result of physical trauma to tissue from cheek biting or cheeks rubbing on teeth/fillings/crowns. The skin basically overgrows keratin as a protective measure. Leukoplakia is diagnosed based on it not being able to be identified as any other type of lesion. Causes of leukiplakia remain unknown, but are associated w/ tobacco, alcohol, uv radiation, microbes or trauma.
