If you want to take treatment after an ulcer on your tongue, you can do so in two ways. The first aspect is local, you can apply drugs to the local ulcer surface, such as watermelon cream, Yunnan Baiyao, and open throat sword spray, which can effectively promote the healing of the ulcer surface and reduce pain. In addition, the application of epidermal growth factor on the ulcer surface can also accelerate the healing of the ulcer surface. These drugs are biological agents and are generally not recommended if the ulcer is not obviously and particularly painful. The second method is systemic treatment, which can be applied to the whole body to improve drugs such as pidomod and transfer factor, which can effectively improve the body’s immunity, reduce the chance of recurrence of mouth ulcers, and also have a certain effect on the healing of mouth ulcers.
