Damaged tissue will slough off on its own, just like when you get a sun burn, your skin peels where it has been damaged. For now I wouldn't worry too much about this, it is probably just this healing process. If it is still happening two weeks from now, that is another issue. But my GUESS, is that it won't be. In the mean time, keep your mouth really clean, and it won't hurt if you GENTLY, WITH A VERY SOFT BRUSH, keep that sore area of your gum tissue clean also.
