i think it’s been almost a week now, and my canker sore hasn’t gone away. its still painful and now i see a red sort of sore over it, and a white mark where it is too. there is a lot of friction there with my molars. is this something i should worry about? im a bit sick so maybe it is delaying its healing… any tips for pain, what I should do?
Apply butter. This will soothe the area and will heal it in few days. This home remedy always worked for me.
