You suddenly got a black spot on your tongue it does not hurt and is hairy what can be?

The most likely cause of a hairy black spot on your tongue that does not hurt is a condition called lingua villosa nigra. This is a harmless condition that occurs when the tiny bumps (papillae) on the back of your tongue become elongated and trap food particles and bacteria. This can cause the affected area to appear black or brown and hairy.

Lingua villosa nigra is not usually a cause for concern and does not require treatment. However, if the condition is bothersome or does not improve after a few weeks, you may want to see your doctor. Treatment typically involves gently brushing the affected area with a soft toothbrush or tongue scraper.

Other possible causes of a black spot on your tongue include:

* _Oral thrush: This is a yeast infection that can cause white or black spots on the tongue. Thrush is more common in people with weakened immune systems.

* _Oral cancer: This is a rare but serious condition that can cause black spots on the tongue. Oral cancer is more common in people who smoke, drink alcohol heavily, or have a family history of the disease.

* _Iron deficiency: This can cause the tongue to look pale or have black spots.

* _Addison's disease: This is a rare condition that affects the adrenal glands. Addison's disease can cause the skin and oral mucosa to appear dark.

* _Drugs: Certain drugs, such as antibiotics and chemotherapy, can cause the tongue to become black.

* _Vitamin B12 deficiency: This can lead to a condition called glossitis, which can cause the tongue to be smooth and beefy looking with or without areas of darkening of pigment. Some vitamin B12 deficiencies present only with blackening of the tongue that may be the only finding for some time if untreated._
