Don't go by me but I also wouldn't go by the doctor in this case. There is certainly something going on. I've had white tongue for the last few years and my health has not been very good. I went to ENT doc for sinuses and mentioned my obviously completely white tongue. The moron told me it was perfectly normal but proceeded to prescribe Celebrex for whatever reason I don't know. Needless to say I ripped up the script in the parking lot. Sounds like you need some cleansing here regardless of what the expert docs say.
