Glossodynia- Burning mouth syndrome (BMS)
Glossodynia, or burning mouth syndrome, is a chronic pain syndrome that causes mouth pain, dry mouth, and taste disorders. Areas affected include the whole mouth or single areas like the tongue, lips, gums, inside cheeks, or throat. Sometimes, glossodynia is also referred to as burning tongue syndrome, as the burning tongue sensation is the most noticeable symptom.

- Tongue pain symptoms may come and go throughout the day, or they may intensify as the day progresses.
- Burning tongue symptoms may linger for years, unless treated.
