Someone tell me why. Basically, I'm scraping loose, seemingly dead tissue from the underside of my tongue on nearly a daily basis. This has been going on for as long as I can remember, so we are talking 20+ years. My doctor cannot seem to provide a good explanation, but doesn't appear concerned. As he put it, "If it was anything serious, you'd be dead by now." My dentist was also stumped. The only thing that I notice tends to affect is somewhat is that it is more pronounced after a night of drinking.... Anyone have any idea what this is about?
