My gums are feeling sore and my lower lip, from the inside is inflamed and has three areas where the inner skin seem to have been torn/cut. I did not knock my face and not sure how this came about. I had this problem for the last three days. I rinse my mouth with salt water. It helps a bit. I change toothbrush and I am not sure what else I need to do to get rid of the pain. I can eat, but I would enjoy the food better had I not had this discomfort.
