Recurrent oral ulcers

Recurrent oral ulcers have become a common medical condition, significantly disrupting daily life. They cause discomfort during eating and oral pain; some individuals experience frequent recurrences. So, what causes recurrent oral ulcers?

Recurrent Oral Ulcers

Currently, oral ulceration remains a complex and challenging medical issue with no single definitive cure. Its etiology is multifactorial—ranging from compromised immune function and vitamin deficiencies to excessive psychological stress—all of which may contribute to recurrence. Patients should pay attention to dietary balance, increase intake of vitamins, ensure adequate rest, and engage in moderate physical exercise to enhance their immune system. During flare-ups, maintaining good oral hygiene and using appropriate medications are also recommended.

Local treatment for recurrent oral ulcers should focus on anti-inflammatory and analgesic effects, prevention of secondary infection, and promotion of ulcer healing. For refractory periadenitis mucosa necrotica (a severe form of recurrent oral ulcer), intralesional injection of triamcinolone acetonide suspension or prednisolone acetate suspension mixed with procaine into the base of the ulcer may be performed once weekly. Systemic therapies aimed at reducing recurrence frequency and alleviating symptoms are also employed. In Traditional Chinese Medicine (TCM), pattern differentiation (e.g., deficiency vs. excess) guides treatment, and adjunctive physical modalities—including laser therapy, ultrasound, nebulization, microwave therapy, and ultraviolet radiation—may be utilized.

In daily life, patients should maintain a light diet rich in vegetables and fruits, and avoid spicy or irritating foods such as chili peppers and garlic. We hope this information proves helpful to you.
