How to Treat Recurrent Aphthous Ulcers

After developing oral ulcers, patients not only must avoid acidic foods but also experience discomfort while eating, and the ulcers frequently recur. So, how are recurrent oral ulcers treated?

How to Treat Recurrent Oral Ulcers

Treatment for recurrent oral ulcers should be tailored according to their underlying causes: First, recurrent oral ulcers may result from deficiencies in certain trace elements. Patients should visit a hospital for testing—such as for vitamin B or zinc levels. If deficiency is confirmed as the cause, appropriate supplementation is recommended—for example, vitamin B complex supplements or oral zinc gluconate solution. Once trace element balance is restored, recurrent oral ulcers can be effectively resolved.

Second, if recurrent oral ulcers stem from reduced immune resistance—often due to chronic sleep deprivation—immune-enhancing agents (e.g., transfer factor) may be prescribed. Patients are advised to maintain regular daily routines, avoid staying up late, and refrain from consuming spicy or irritating foods. Alternatively, topical medications that promote ulcer healing—such as triamcinolone acetonide gel or “Xigua Shuang” (a traditional Chinese herbal spray)—may be used.

Frequent emotional stress or anger can also trigger recurrent oral ulcers. To help prevent them, patients may take heat-clearing (cooling) medications or consume cooling fruits—such as pears, dragon fruit, or apples. We hope this information proves helpful!
