Introduction
Infant oral ulcers can be improved through oral hygiene care, adjustment of feeding methods, local physical soothing measures, topical pharmacological interventions, and identification of underlying contributing factors. Different approaches are appropriate for varying degrees of ulcer severity, helping to alleviate local discomfort and promote gradual healing of the damaged mucosa. If persistent refusal to feed, recurrent fever, or other concerning symptoms occur, prompt medical evaluation and treatment at a hospital are recommended.

Infant oral ulcers can be improved through oral hygiene care, adjustment of feeding methods, local physical soothing measures, topical pharmacological interventions, and identification of underlying triggers. Different approaches are suitable for varying degrees of ulcer severity, helping to alleviate local discomfort and promote gradual healing of the damaged mucosa. If persistent refusal to feed or recurrent fever occurs, prompt medical evaluation and treatment at a hospital are recommended.

1. Oral Hygiene Care: After each feeding, offer a small amount of warm water to rinse residual milk from the infant’s mouth, minimizing contact between milk residue and the ulcerated area. Gently wipe the oral mucosa with a soft gauze pad, using light, careful motions to avoid further trauma to the lesion. This helps reduce bacterial colonization and supports the mucosa’s natural self-repair process.

2. Adjustment of Feeding Methods: Ensure milk temperature is moderate—avoid excessively hot milk, which may irritate the ulcer. Regulate feeding pace according to the infant’s needs to minimize crying. For breastfeeding, maintain thorough nipple hygiene; for bottle-feeding, ensure proper sterilization of all feeding equipment. These steps reduce external irritation and repeated mechanical stimulation of the ulcer, thereby alleviating pain during feeding.

3. Local Physical Soothing: Maintain appropriate indoor humidity to ensure a comfortable, non-drying environment, thus minimizing adverse effects of dry air on the oral mucosa. Closely monitor the infant’s mental state and strive to reduce crying episodes, as excessive crying exacerbates oral mucosal congestion and hinders optimal healing conditions at the ulcer site.

4. Topical Pharmacological Intervention: Apply age-appropriate topical medications directly to the ulcerated area to reduce local inflammation and relieve burning pain. Always follow professional guidance regarding dosage and frequency of application, and carefully observe the infant’s response to treatment to prevent potential adverse reactions.

5. Identification of Underlying Triggers: Assess the infant’s overall health status to determine whether the ulcer stems from trauma, infection, or nutritional deficiency. Document the frequency of ulcer occurrences and the size of lesions. Once the root cause is identified, eliminate associated contributing factors to decrease recurrence risk and minimize interference with feeding.

Routinely disinfect all feeding utensils, monitor the infant’s nutritional intake, and regularly inspect the oral mucosa. Early detection and timely management of any abnormalities help mitigate the impact of oral ulcers on feeding and overall physical development.
