What should be done if a six-year-old child frequently gets mouth ulcers?

When a six-year-old child frequently experiences oral ulcers, parents can take the following measures: 1. Dietary adjustment: Ensure the child's diet is balanced, with increased intake of foods rich in vitamin B2, vitamin C, and trace elements such as zinc, including oranges, apples, kiwifruit, carrots, and animal liver. Avoid spicy, irritating, and fried foods to reduce irritation to the oral mucosa. 2. Medication: In cases where oral ulcers are not severe, topical medications such as Kehoujian spray can be used for local treatment. If ulcers affect eating, antiviral or anti-anaerobic infection medications, such as acyclovir tablets or metronidazole tablets, may be added under a doctor's guidance. 3. Oral hygiene: Teach the child to maintain good oral hygiene habits, rinse the mouth with mild salt water, and brush teeth in the morning and evening. 4. Enhance immunity: Ensure the child has adequate sleep and avoid excessive fatigue to improve the body's immune function. If oral ulcers recur frequently or persist without healing, it is recommended to seek timely medical attention to rule out other potential underlying causes.
