Tongue problems


Tongue problems include pain, swelling, or a change in how the tongue looks.

Alternative Names

Dark tongue; Burning tongue syndrome - symptoms


The tongue is mainly made up of muscles. It is covered with a mucus membrane. Small bumps (papillae) cover the upper surface of the tongue.

There are many different reasons for changes in the tongue's function and appearance.


Tongue movement problems are most often caused by nerve damage. Rarely, problems moving the tongue may also be caused by a disorder where the band of tissue that attaches the tongue to the floor of the mouth is too short. This is called ankyloglossia.

Tongue movement disorders may result in:


Taste problems can be caused by damage to the taste buds, nerve problems, side effects of medications, an infection, or other condition. The tongue normally senses sweet, salty, sour, and bitter tastes. Other "tastes" are actually a function of the sense of smell.

Tongue swelling occurs with:

The tongue may get wider in persons who have no teeth and do not wear dentures.

Sudden swelling of the tongue can happen due to an allergic reaction or a side effect of medications.


Color changes may occur when the tongue becomes inflamed (glossitis). Papillae (bumps on the tongue) are lost, causing the tongue to appear smooth. Geographic tongue is a patchy form of glossitis where the location of inflammation and the appearance of the tongue change from day to day.


Hairy tongue is a harmless condition in which the tongue looks hairy or furry. The disorder usually goes away with antibiotics.


Sometimes the upper surface of the tongue turns black or brown in color. This is an unsightly condition but it is not harmful.


Pain may occur with glossitis and geographic tongue. Tongue pain may also occur with:

After menopause, some women have a sudden feeling that their tongue has been burned. This is called burning tongue syndrome or idiopathic glossopyrosis. There is no specific treatment for burning tongue syndrome, but capsaicin (the ingredient that makes peppers spicy) can offer relief to some patients.


Minor infections or irritations are the most common cause of tongue soreness. Injury, such as biting the tongue, can cause painful sores. Heavy smoking can irritate the tongue and make it painful.

A viral ulcer, also called a canker sore, commonly appears on the tongue (or anywhere in the mouth) for no obvious reason. Some doctors believe that these ulcers are linked to emotional stress or fatigue, although this has not been proved.

Canker sores will heal on their own.

See your dentist if you have a tongue problem caused by dentures.

Antihistamines can help relieve a swollen tongue caused by allergies. You should avoid the food or drug that causes the tongue swelling. Seek medical attention right away if swelling is starting to make breathing difficult.
