What Causes Frequent and Persistent Mouth Ulcers?

Recurrent oral ulcers are a common source of distress for many patients. When oral ulcers occur frequently and their underlying cause remains unclear, the frequency of episodes may increase. So, what causes recurrent oral ulcers?

What Causes Recurrent Oral Ulcers?

Frequent oral ulcers may be associated with various factors, including reduced immune function, vitamin deficiencies, and others. Additionally, staying up late or sudden changes in sleep patterns can disrupt hormonal balance, potentially triggering oral ulcers. Excessive work-related stress or heightened psychological pressure may also contribute to their development. A genetic predisposition cannot be ruled out either. It is recommended to consume more fresh fruits and green vegetables—such as carrots, apples, kiwifruit, and bananas—in daily diet.

For localized treatment of recurrent oral ulcers, anti-inflammatory and analgesic medications may be used, aiming to prevent secondary infection and promote ulcer healing. In severe cases, intralesional injection of triamcinolone acetonide suspension or prednisolone acetate suspension mixed with procaine into the base of the ulcer may be employed. Systemic therapy may also be administered to reduce recurrence. Traditional Chinese medicine (TCM) approaches—including syndrome differentiation for deficiency or excess—and physical therapies such as laser, ultrasound, and ultraviolet radiation may also be utilized.

When experiencing recurrent oral ulcers, it is essential to promptly consult a dentist or oral medicine specialist to identify the underlying cause and receive targeted treatment under professional guidance. We hope this information proves helpful to you!
