Hi, for years I have had to scrap the inside of my mouth on the cheek area because of an overproduction of dead white skin. Some times it's just a line of dead skin on one side of my mouth, and there is a sore, but it seems like it's always the entire cheek area that has an overproduction of dead skin. It usually resolves itself at some point, but it always comes back and I find myself scrapping the skin on the inside of my mouth. My dentist has never said anything about it, and I have had this problem well over 10 years. Wondering if something is terribly wrong.
