My mother is 55 years old. She has problem in oral cavity. Her inner cheek on both sides have been greyish for last year. And she feel irritation only while consume spicy food. Her one jaw was slightly loose at starting before this condition happened, she tried to remove the jaw herself as she thought it has been old, but didn't get success. She visit a dentist regarding loose teeth. Doctor prescribed some medicine and oral wash after scaling the teeth and the problem vanishes but this new problem started which is greyish cheek in early time only in right side but now it is also in left side. It does not cause any problem except irritation towards spicy food. But I want to know -how to get rid of pigmented inner cheek and the irritation that cause only when consume spicy food. Please advise best to get relief from this situation. It is happening from last 10 months. I consulted many doctors and got various response like some doctor said leukoplakia, some said candidiasis, some said oral lichen planus some said fibrosis some said gastrointestinal problem but my mother has no any previous record of any disease. No any constipation or indigestion problem. No b.p no diabetes .i don't know what to do? Thank you.
