Black, hairy tongue

Definition:
Black, hairy tongue

Black, hairy tongue is a temporary, harmless (benign), painless oral condition that gives your tongue a dark, furry appearance. The distinct look of black, hairy tongue usually results from an overgrowth of bacteria in the mouth.

Although black, hairy tongue may look alarming, it doesn't cause any health problems. Black, hairy tongue usually resolves without medical treatment.

Symptoms:

Signs and symptoms of black, hairy tongue include:
  • Black, yellow or brown discoloration of the tongue
  • A hairy or furry appearance of the tongue
  • Altered taste or metallic taste in mouth
  • Bad breath (halitosis)
  • Gagging sensation in some people
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
  • Your signs and symptoms persist for more than 10 days

Causes:

Black, hairy tongue typically results when projections on the tongue called papillae grow longer (elongate) and don't shed like normal. This makes the tongue look hairy. Debris, bacteria or other organisms can collect on the papillae and result in black, yellow or brown discoloration.
The cause of black, hairy tongue can't always be determined. However, potential causes include:
  • Changes in the normal bacteria or yeast content of the mouth following antibiotic use
  • Poor oral hygiene
  • Breathing through your mouth
  • Medications containing bismuth, such as Pepto-Bismol
  • Regular use of mouthwashes containing oxidizing agents, such as peroxide, or astringent agents, such as witch hazel or menthol
  • Heavy tobacco use

Treatments and drugs:

Black, hairy tongue typically doesn't require medical treatment. Though unattractive, it's a temporary, harmless condition.

Practicing good oral hygiene and eliminating factors that potentially contribute to the condition — such as tobacco use or medications that contain bismuth — help resolve black, hairy tongue. Talk to your doctor or dentist before discontinuing a prescribed medication.
