Black hairy tongue

Black hairy tongue is a temporary, harmless oral condition that gives the tongue a dark, furry appearance. The distinct look usually results from a buildup of dead skin cells on the many tiny projections (papillae) on the surface of the tongue that contain taste buds.

These papillae, which are longer than normal, can easily trap and be stained by bacteria, yeast, tobacco, food or other substances.

Although black hairy tongue may look alarming, typically it doesn't cause any health problems, and it's usually painless. Black hairy tongue usually resolves by eliminating possible causes or contributing factors and practicing good oral hygiene.

Symptoms

Signs and symptoms of black hairy tongue include:

Black discoloration of the tongue, although the color may be brown, tan, green, yellow or white

A hairy or furry appearance of the tongue

Altered taste or metallic taste in your mouth

Bad breath (halitosis)

Gagging or tickling sensation, if the overgrowth of the papillae is excessive

When to see a doctor:

Though unattractive, black hairy tongue is usually a temporary, harmless condition.

See your doctor if:

You're concerned about the appearance of your tongue

Black hairy tongue persists despite brushing your teeth and tongue twice daily.

Black hairy tongue typically results when projections on the tongue called papillae grow longer because they don't shed dead skin cells like normal. This makes the tongue look hairy. Debris, bacteria or other organisms can collect on the papillae and result in discoloration.

Although the cause of black hairy tongue can't always be determined, possible causes or contributing factors include:

Changes in the normal bacteria or yeast content of the mouth after antibiotic use

Poor oral hygiene

Dry mouth (xerostomia)

Regular use of mouthwashes containing irritating oxidizing agents, such as peroxide

Tobacco use

Drinking excessive amounts of coffee or black tea

Excessive alcohol use

Eating a soft diet that doesn't help to rub dead skin cells from your tongue.
