Hi, I recently cut my gum eating flatbread. It was a pretty nasty cut but I did not think anything of it until now because it still is sore and has not really healed. This may be because I did not realize how big the cut was and was irritating it while brushing. Nonetheless, it exposed a spot that I cannot tell if is a bruise, an exposed upper tooth, or an infection. It above my left middle big tooth and is white matching the color of my teeth. I am going to schedule a dentist appointment if it does not heal in the next few days / look any better but I was wondering if there are any signs I should be looking for now.
