I doesn't seem precancerous.
I started brushing my teeth like 5 times a day and try to remember mouth wash when flossing.
It doesn't hurt when I eat, anymore. 1st, lining of skin in my mouth fell off.
I just got a soft toothbrush and soft floss. I also started brushing my tongue.
I've smoked 2 cigarettes and a few vapor samples.
Ulcer!
