question: I have a bump on the outside of my upper jaw that is the same colour as my gums, and slightly painful. The dentist removed it and it grew back. I flossed it off by accident, it bled a little, and it grew back. It has not changed in size, but won t seem to go away. I was thinking it might be a skin tag? My dentist doesn t know what it is, but doesn t seem to be worried. Should I be getting a second opinion?
