| Re: yellow substance on back of tongue
i notice if i drink coffee there is a yellowish tint to the back area of my tongue. when i swallow that part doesn't touch the roof of my mouth and there is somewhat a slime? ...sounds gross but that is the best way to describe it. my advise to you is, use listerine and gargle twice a day, and brush your tongue or get a tongue scraper/cleaner. do this before you brush. hope this helps!
