question: I have a strange swollen spot behind my right front tooth. I have no idea what causes it, but I get it every so often. It is not painfull, but it is annoying because when I close my mouth, it touches my tongue, and it also impacts my speech alittle. In terms of looks, it can get somewhat big and white, it looks sortof like another tooth that is behind my right front tooth, except it is soft.I need to know what this is and how to grt rid of it.
