Tongue

Glossitis is a condition in which the tongue is swollen and changes color. Finger-like projections on the surface of the tongue (called papillae) are lost, causing the tongue to appear smooth.

Tongue inflammation; Tongue infection; Smooth tongue; Glossodynia; Burning tongue syndrome

Changes in the appearance of the tongue may be a primary condition (not due to another disease or event), or it may be a symptom of other disorders (a secondary condition).

Glossitis occurs when there is acute or chronic inflammation of the tongue.
