Quick Review

Hairy tongue, or black hairy tongue (brown, yellow, green, etc. hairy tongue) is a benign change of the top surface of the tongue.  It is characterized by elongation of the many small nodules (filiform papillae) of the surface to that they resemble stubby hairs.  They can become stained, usually black from coffee, tea, cokes or colored bacteria.  Cause is unknown but it is usually seen during antibiotic use, in smokers, in persons using stomach antacids, or in hospitalized or debilitated patients.  Usually it is asymptomatic but may produce bad breath and may cause a burning sensation.  Treatment is to scrape the tongue.  It may recur.
