There is no data to support how long it usually takes for lingual inflammation to heal on its own, so it is not yet possible to tell specifically. Tongue inflammation is an inflammation of the special anatomical part of the back of the tongue caused by infection, iron deficiency, anemia, vitamin deficiency and other reasons during the development of the tongue. Patients may present with a tongue accompanied by blotchy lesions, numbness, and burning pain. Tongue infections include atrophic glossitis, median rhomboid glossitis, map tongue, furrowed tongue, and hairy tongue. Some tongue diseases, such as hairy tongue, can gradually return to normal after removing irritating factors and strengthening oral hygiene. Map tongue is self-limiting, with intervals of remission, the surface of the tongue mucosa can be completely normalized. However, due to the degree of the patient’s condition, personal constitution and other reasons are different, so there are individual differences in self-healing, so the specific can not be judged. It is recommended that patients with lingual inflammation go to the hospital in time and follow the doctor’s instructions for treatment to avoid delaying the condition.
