A painful tongue is often caused by something simple, like accidentally biting it or burning it with hot food or drink. However, sometimes a sore tongue indicates a more serious underlying condition.
Common Causes of Tongue Pain:
- Trauma: Biting your tongue, scalding it with hot food or drinks, or even harsh brushing can cause immediate pain and swelling. This usually resolves within a few days. (Source: NHS, WebMD, Medical News Today)

Less Common Causes of Tongue Pain:
- Oral Thrush: A fungal infection in the mouth can cause a painful, white coating on the tongue. (Source: Medical News Today)
- Burning Mouth Syndrome (BMS): This condition causes a persistent burning sensation in the mouth, often affecting the tongue. (Source: National Institute of Dental and Craniofacial Research)
- Tongue Cancer: While less common, a persistent, painful lump or sore on the tongue that bleeds easily and doesn't heal should be evaluated by a doctor immediately. (Source: Moffitt Cancer Center)
When to See a Doctor:
Persistent tongue pain, especially if accompanied by other symptoms like swelling, bleeding, difficulty swallowing, or changes in taste, warrants a visit to a healthcare professional. They can diagnose the cause and recommend appropriate treatment. (Source: Cleveland Clinic)
