Anti-inflammatory drugs are useful if the ulcer is due to a bacterial infection. If the ulcer is due to a viral infection, such as a herpetic ulcer, antiviral medications such as acyclovir, ribavirin, acyclovir ointment, and valacyclovir are needed to promote healing. For traumatic ulcers, it is necessary to remove local irritants to promote healing, such as sharp tooth tips caused by residual roots, crowns, caries, or poor restorations, which need to be resharpened, extracted, or removed to promote healing. If the deficiency is due to vitamin deficiency, taking anti-inflammatory drugs is usually useless. Vitamin deficiency mainly requires vitamin supplementation, and a certain amount of complex vitamins are needed to be able to heal the ulcer effectively. For the ulcer surface, medications that promote ulcer healing are usually used, which usually include ulcer patches, compounded boric acid solution, and also recombinant human epidermal growth factor gel or other topical medications can be used. In addition, furacilin can be used to promote the healing of ulcers. It is also important to ensure oral hygiene and to improve the body’s resistance so that the ulcers do not recur.
