There are several conditions that can occur inside the mouth that can produce spots in the mouth, I was just trying to see if I could help narrow it all down. You could find a symptom checker online and see if you can identify what it is, at least then you would know, and maybe be able to do something about
it at home.
I had a mild case of 'geographic tongue' myself less than a year ago. I know my doc did some extra acupuncture and I increased my kefir intake and in a couple of weeks, it was gone. Did what my doc & I do do anything? I don't know for sure, but it was better than not doing anything!
