4-5 days ago , I found these white spots and tiny little bumps on my gums. They don’t hurt, but they are little dry. I tried to wash it off, but it wouldn’t come off, but after I woke up next morning, it looks like it has gotten bit smaller and paler (I don’t mean more white). My own dentist said it most likely is nothing serious and is maybe flu related (I had flu 1 week ago and have still little bit) or fungus. Could this leukoplakia or possibly even mouth cancer? Or is it like the other doctor said (nothing serious)? Should I be worried? Should I book appoitment to another dentist?
