A 64-year-old man got a medical checkup after his tongue began sprouting green"hairs." The bizarre-looking fuzz turned out to be caused by a fairly common and harmless condition known as hairy tongue.
Upon closer inspection, physicians noticed that the man's filiform papillae — the tiny, cone-shaped bumps that cover the surface of the tongue and give it its rough texture — were longer than what would be expected on a healthy tongue. The doctors saw no other signs of injury or disease and the patient reported no pain or change in his sense of taste.
When they are not regularly shorn off, the papillae can grow up to 0.7 inches long and lead to hairy tongue. The condition affects about 13% of people at some point in their lives, the majority of cases being in men and patients over 65, according to the American Academy of Oral Medicine.
