Considerations:
The tongue is mainly composed of muscles. It is covered with a mucous membrane. Small bumps (papillae) cover the upper surface of the tongue. Between the papillae are the taste buds, which allow you to taste. The tongue moves food to help you chew and swallow. The tongue also helps you form words. There are many different reasons for changes in the tongue's function and appearance. DIFFICULTY MOVING THE TONGUE Tongue movement problems are most often caused by nerve damage. However, problems moving the tongue may also be caused by ankyloglossia, a disorder where the band of tissue that attaches the tongue to the floor of the mouth is too short. Tongue movement disorders may result in speech difficulties or difficulty moving food during chewing and swallowing. TASTE ABNORMALITIES 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. ENLARGEMENT OF THE TONGUE Tongue swelling occurs with Down syndrome, acromegaly, myxedema, amyloidosis, rhabdomyoma, and other disorders. The tongue may get wider in persons who have no teeth and do not wear dentures. COLOR CHANGES Color changes may occur with inflammation of the tongue (glossitis). Papillae 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 Hairy tongue is a harmless condition in which the tongue looks hairy or furry. Its appearance can be worrisome. The disorder usually goes away with antibiotics. BLACK TONGUE Sometimes the upper surface of the tongue turns black or brown in color. This is an unsightly condition but is not harmful. PAIN IN THE TONGUE This may occur with glossitis and geographic tongue. Tongue pain may also occur in with diabetic neuropathy, oral cancer, mouth ulcers, and leukoplakia. 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.
Common Causes:
Minor infections or irritations are the most common cause of tongue soreness. Injury, such as biting the tongue, can cause painful sores. Heavy smoking will 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 apparent reason. Some doctors believe that these ulcers are linked to emotional stress or fatigue, although this has not been proved. Possible causes of tongue pain include: Possible causes of tongue tremor: Possible causes of white tongue: - Local irritation
- Smoking and alcohol use
Possible causes of smooth tongue: Possible causes of red (ranging from pink to magenta) tongue: Possible causes of tongue swelling: Possible causes of a hairy tongue: Possible cause of grooves in the tongue: - Birth defect -- normally occurs in 10% of population
