I have a small patch of rough skin on the inside of my right cheek by my back molars. I cant tell if its been thickened by biting that spot or not, I do have some trouble with my tmj on the right side being that I have to pop it sometimes to relieve pressure in the joint. Would that cause me to be biting my cheek on the inside? It doesnt really look like white or red or anything just had an indentation pressed into it, Im assuming from my teeth or the way I have my cheek muscled flexed against my teeth. It is about a quarter inch in from the back of my jaw muscles.  Should I be worried about cancer or anything ? I have no other mouth changes except this and will be going to a dentist here in a couple days.
Hello, A small area of rough skin on the inside of the cheek can be due to cheek biting, any sharp cusp of tooth rubbing against the cheek, burning with hot foods' etcetera. It is not cancerous and does not look at anything that has to be worried about it. You can keep a watch over it and in case if it spreads or changes color consult an oral physician and get evaluated. For now, you can do warm saline gargles. Avoid eating very hot or hard foods. Hope I have answered your query. Let me know if I can assist you further.
