question: I got a mouth guard, and I noticed the inside of my cheeks in my mouth started to pop out into the line between my teeth. I bit them off and now its the same thing but white. I stopped biting it off seeing if it would go away but its all just loose skin like a scab falling off. so I bite it off but it keeps coming back. it doesnt hurt.. Its loose enough to even just scrape off with my nail. Its annoying having in here and Im really wondering what it is.
