Black Tongue Causes
- Hyperpigmentation: It refers to a condition in which there is excessive release of the pigment. Cells that contain melanin are known as melanocytes are responsible for the color of the tongue and skin. Their presence in larg numbers also causes the appearance of black spots. Other causes may include intake of certain kinds of medication, low production of hormones by the adrenaline glands and the age of the individual. Most often, the spots are harmless.
- Oral Cancer: People who are in the habit of chewing tobacco or old beetle may be at the risk of oral cancer. Sometime the cancer cells may affect the tongue, gums and others parts of the mouth. Even those who experience frequent cuts or lesions on the tongue may be affected by cancer. It includes thickening of the patch and formation of ulcers on the tongue. In severe cases, it may also cause pain. Black spots are also observed in patients undergoing chemotherapy and they disappear once the chemotherapy treatment is stopped.
- Hairy Black Tongue: It usually affects the back and mid region of the tongue. The tongue may appear to have black furry patches of hair. This happens because papillae on the tongue trap dead cells. These cells get discolored and turn black. Along with it, people may also experience bad breathe and a metallic taste in their mouth. Such a condition may occur due to lack of oral hygiene or infection by bacteria or yeast.
- Alcohol Consumption and Smoking: Smoking as well as alcohol consumption may cause the appearance of black spots on the tip, side and under the tongue. People who smoke are more prone to oral cancer. Moreover, it also causes hyperpigmentation. The presence of black long papillae is found mostly among smokers. This gives the tongue a dark and hairy appearance.
- Reaction to medications: People may be allergic to certain medications that could cause dark spots or bumps on the tongue. Medications such as anti depressants, asthma drugs, some kinds of antibiotics and medicines that contain bismuth salicylate commonly cause the appearance of black spots on the tongue. Allergic reactions may cause staining of the tongue.
- Oral Mucocele: When the salivary glands in the mouth get damaged or blocked, a cyst like lump forms in the mouth. These bumps may be found under the tongue and they are usually deep blue or almost black in color. They are known as oral mucocele. They commonly appear at the side, on the surface or below the tongue. Lip biting and trauma can cause such a condition. These bumps are harmless and go away on their own.
- Oral Fibroma: It is a smooth, round lump attached to the oral cavity tissue by the stalk at its base. They are similar to freckles and moles and may irritate the teeth, dental appliance and piercings. Often these may reoccur even if they are surgically removed from the mouth.
- Tongue piercing: When a piercing is made on the tongue, it takes some time to heal. After it has healed the color goes back to normal. However, special care must be taken to maintain oral hygiene while the piercing is still healing. If proper care is not taken, it can lead to bacterial infections or other infestations.
- Blood Blisters: People may bite their tongue or cheek accidentally due to ill fitting dentures or due to stress. Whatever is the reason, it can cause the formation of blisters filled with blood. These are harmless and disappear when the injury heals.

Dark spots on the tongue may occur due to staining from fillings. It is also called amalgam fillings or amalgam tattoos.

The spots on the tongue are usually accompanied by other symptoms that help to conclude HIV or STDs as the probable causes.
- Anemia: Anemia is a condition of a low level of red blood cells in the body. The tongue often helps to diagnose a condition of anemia. Although a pale tongue is the most common sign of anemia, the presence of clustered or scattered dark spots on the tongue can also imply that a person is anemic.
- Pregnancy: There are many hormonal changes in the body during pregnancy and as a result black spots may appear on the tongue. Also, the intake of contraceptives causes hormonal changes leading to black spots on the tongue.
- Babies – Dark spots may also appear on the tongue of babies due to allergic reactions or oral thrush. In such cases, the spots may be either black or white.
