I have a crack in my tongue, which seems to be hereditary. After the examination, there may be a crack in my tongue. I want to ask anyone who knows, can this tongue be cured? What food is good for the tongue? Congenital patients may be caused by tongue muscle dysplasia and generally do not need treatment. The key is to pay attention to oral hygiene, pay more attention to gargle, and prevent food residue from staying in the gap. This disease can also be left untreated because the treatment is not very good. If there is inflammation, drugs, physical therapy (such as oral ultraviolet lamp irradiation) and surgery can be used for treatment. Vitamins and trace elements are used for systemic medication. 2%-4% disodium hydrogen phosphate solution can be used locally to gargle.
