Hairy tongue: Taste buds on the tongue sit on raised protrusions of the tongue surface called papillae. Various conditions can interfere with the normal shedding of tongue cells and cause the papillae to get longer and look hairy. Can appear whitish or can be stained yellow, brown or black from drinking coffee, tea, coke etc. To read more about this enter just bit.ly/1ERevLa in the search box.
