About Tongue Disorders

Your tongue helps you taste, swallow, and chew. You also use it to speak. Your tongue is made up of many muscles. The upper surface contains your taste buds.

Problems with the tongue include:

  • Pain
  • Swelling
  • Changes in color or texture
  • Abnormal movement or difficulty moving the tongue
  • Taste problems

These problems can have many different causes. Treatment depends on the underlying problem.

It sits within Mouth and Teeth.

When to speak to someone. Reading about a topic cannot tell you whether it applies to you. Speak to a doctor or pharmacist if symptoms are severe, sudden, getting worse, or simply not going away — and seek emergency care immediately for chest pain, breathing difficulty, sudden weakness or confusion, or a serious allergic reaction.

Research on Tongue Disorders

402 studies areregistered for this condition on ClinicalTrials.gov, the U.S. National Library of Medicine's public registry. A selection is below — the links go straight to the registry entry, not to a summary of ours.

What a registered study does and does not mean. Registration means a study exists and has been declared publicly. It says nothing about whether the treatment being tested works, is safe, or is available to you. Many studies find no benefit — that is what research is for. Never seek out an experimental treatment on the strength of a registry entry alone.
