I just happened to be looking at my mouth and noticed that I have sometihng under on one side. One part looks like a small (flesh colored) area with 3 or 4 little whiteheads together (under the left back side of my tongue) & I also noticed a flesh colored bump/flap next to the frenelum (spelling?) aka center divider under your tongue. The white spots/white heads cluster makes me nervous Im not sure what it could be. Cankersore? Some kind of infection? My mouth is clean I was at the dentist january-had my cleaning recently. Does anyone know what this is? & Part 2- I'm not sure if Ive always had that bump/ flap of skin under my tongue should I get a check up to make sure its not cancerous? What does beginnings of oral cancer look like? I do smoke, Im young & I do have heartburn if it helps.
