Remedies for a sore tongue include over-the-counter pain medications or leaving the sore alone and allowing it to resolve itself, states Healthline. Remedies depend on the cause of the pain.
A sore tongue often results from canker sores or after getting bitten, according to Healthline. When this occurs, the individual needs to avoid spicy food until the sore goes away on its own. For severe cases, over-the-counter treatments can ease the pain until the sore heals. Cancer, anemia and neuralgia can also cause tongue pain. Sores caused by cancer treatments take a few days to up to several weeks to resolve, explains Mayo Clinic. Certain antiviral medications can help treat these sores. An individual with cancer can treat and decrease the risk of getting tongue sores by practicing good oral hygiene and rinsing or gargling with mouthwash several times a day.
Because smoking exacerbates tongue sores, a person should reduce or cease smoking entirely, notes Healthline. A sore tongue can also be caused by dehydration, dry mouth and thrush, says MedicineNet. The latter is caused by a fungal infection that clears up with medications. An individual with a sore tongue as a result of dehydration can treat it easily by drinking more fluids.
