The tongue discoloration usually affects the back surface of your tongue, while the tip and sides of your tongue are colored normally. “Hairy” tongue often causes no symptoms and the major problem is its unpleasant appearance.

Black hairy tongue (BHT) syndrome is a benign condition with a specific appearance of your tongue - it becomes dark and looks furry. Despite the name of this condition, the top of your tongue can also be brown, green, white or other colors. BHT affects about 13 percent of Americans. It is more common in men than in women. In most cases, BHT can be eliminated with good oral hygiene that involves the use of a toothbrush or tongue scraper. Rarely, BHT must be treated with medical or surgical treatments.
