How to Treat Oral Ulcers

Oral ulcers can be improved through dietary and lifestyle adjustments, local physical care, topical medications, oral medications, and elimination of local irritants. Most ulcers are associated with fluctuations in immunity, trauma, or nutritional deficiencies, and typically heal spontaneously. However, if an ulcer persists for more than two weeks, becomes excessively large, or recurs frequently, prompt medical evaluation and treatment are recommended.

1. Dietary and Lifestyle Adjustments: Avoid spicy or excessively hot foods; increase intake of fresh fruits and vegetables; ensure adequate sleep. Minimize late-night activities and fatigue to help regulate immune function and reduce mucosal stress, thereby accelerating the repair of damaged oral mucosa.

2. Local Physical Care: Rinse the mouth with warm water or mild saline solution after meals to remove residual food particles. Maintain oral cleanliness to inhibit bacterial growth on the ulcer surface. Avoid repeatedly licking the affected area with the tongue, as this may delay wound healing.

3. Topical Medications: Apply appropriate topical formulations—selected under professional guidance—directly onto the ulcer surface. These agents help alleviate local pain, shield the lesion from external irritation, and accelerate mucosal repair. Ensure oral hygiene before application and monitor for skin tolerance.

4. Oral Medications: When ulcers recur frequently or when overall nutritional status is poor, take prescribed oral medications under professional guidance. Such treatments aim to replenish essential nutrients and modulate immune function to reduce recurrence. Self-medication is not advised.

5. Elimination of Local Irritants: Smooth sharp tooth edges; break habits such as cheek- or lip-biting; and avoid injury to the oral mucosa by hard objects. Removing persistent mucosal irritants helps prevent new ulcers and avoids worsening of existing ones.

In daily life, minimize consumption of irritating foods and maintain a clean oral environment. Avoid touching the ulcerated area with fingers, maintain emotional stability, and adhere to regular routines to facilitate faster recovery of the oral mucosa.
