Uhm... well I never had this white coat on tongue problem , my tongue has always looked pink and healthy. Of course there is a very slight white coating on it,but I think that is normal for healthy people too? It is hardly visible.
As for the back of my mouth eeer,where should I see the mucuous lining?
I actually cant see anything odd in my mouth,but i may be wrong...
but well,never really had problems with my tongue and all...
