Thanks for the replies. I was just hoping someone here may have had a similar experience and could provide some insight. I made another post on a website with dentists and 3 seem to think it's leukoplakia from the picture I posted. Obviously that is no substitute for an in person examination. I have an appointment with my dentist tomorrow morning. I also scheduled an appt with an oral surgeon later this week but I feel I may cancel that as he wants $150 to take a look (exam fee + panoramic x rays). I'd imagine a biopsy or anything else would cost at least $100 extra.
