The name black hairy tongue may sound scary, but the condition is harmless. Black hairy tongue is caused by bacteria or fungi in the mouth, which make the tongue appear black and hairy. It’s easily remedied by good old-fashioned oral hygiene.

Hairy Tongue - Causes, Symptoms and Treatment

Causes of Black Hairy Tongue

A black hairy tongue is caused by too much bacteria or yeast growth in the mouth. The bacteria build up on tiny rounded projections called papillae. These lie along the surface of the tongue. Instead of shedding as they normally do, the papillae start to grow and lengthen, creating hair-like projections. They can grow to 15 times their normal length.

Normally, the papillae are pinkish-white. But as they grow, pigments from food, drinks, and possibly the bacteria or yeast themselves get caught in the papillae, dyeing the tongue a color. Most often that color is black, hence the name. But the tongue can also turn brown, yellow, green, or a variety of other colors.

Certain lifestyle habits and conditions can make people more likely to develop black hairy tongue. They include:

  • Poor oral hygiene
  • Smoking tobacco
  • Drinking a lot of coffee or tea
  • Using antibiotics (which may disrupt the normal balance of bacteria in the mouth)
  • being dehydrated
  • Taking medications that contain the chemical bismuth (such as Pepto-Bismol for upset stomach)
  • Not producing enough saliva
  • Regularly using mouthwash that contains peroxide, witch hazel, or menthol
  • Getting radiation therapy to the head and neck

Black hairy tongue is more common in men, people who use intravenous drugs, and those who are HIV-positive.

Symptoms of Black Hairy Tongue

Other than the appearance of the tongue, most people with black hairy tongue don’t have any symptoms or feel any discomfort. The exception is when there is too much growth of the yeast Candida albicans, which can cause a burning sensation on the tongue. This burning sensation is called glossopyrosis.

Some people complain of a tickling feeling in the back of the roof of the mouth, a metallic taste in their mouth, or nausea. In more severe cases, the condition may lead to a gagging feeling. Sometimes, food getting caught inside the extra-long papillae can cause bad breath.

Treatment of Black Hairy Tongue

Practicing good oral hygiene is the best way to treat black hairy tongue. Gently brush your teeth twice a day with a soft toothbrush. Also, brush your tongue. You can use a tongue scraper to make sure you’re thoroughly cleaning the area. Drink plenty of water throughout the day to help keep your mouth clean.

Other tips include:

  • If you smoke, quit.
  • Add more roughage to your diet. Soft foods won’t clean off the tongue effectively.
  • Call your doctor or dentist if the problem doesn’t get better on its own.
  • Topical medications, such as tretinoin (Retin-A), are also sometimes prescribed.
