Hello everyone. Today I noticed that there's a white spot on my lower gum, on the side. It doesn't bother me much, but sometimes it pops out with a finger. I read somewhere that it could be a pearl or a Bonna knot and nothing serious is wrong. But we will definitely see a doctor anyway. Has anyone encountered something similar and how quickly did it go away?
