I had this about 4 years ago on my lower right gum line
. Dentist did a biopsy to rule out cancer or pre-cancerous cells. He then removed the pat
ch and it has never returned.
Just thought I'd share that
The presence of white or gray colored pat
ches on your tongue, gums, roof of your mouth, or the inside of the cheeks of your mouth may be a sign of leukoplakia.
