How to quickly treat a child's mouth ulcer?

When a child develops oral ulcers, parents can take the following measures to promote faster recovery: 1. **Topical Medication**: Priority should be given to topical treatments, such as analgesic medications (e.g., lidocaine gel), anti-inflammatory drugs (e.g., chlorhexidine mouthwash), and medications that promote healing (e.g., watermelon frost), but these should be used under a doctor's guidance. 2. **Daily Care**: Parents should pay special attention to the child's oral hygiene, encouraging good habits such as brushing teeth in the morning and evening, and rinsing the mouth after meals. At the same time, parents should ensure the child's diet is light and regular, with increased consumption of fresh vegetables and fruits rich in vitamins, while reducing intake of greasy and spicy foods. 3. **Supplement Trace Elements**: Ensure the child has sufficient levels of vitamin B12, vitamin B2, iron, zinc, and other essential trace elements, which are crucial for the recovery from oral ulcers. Parents may appropriately supplement these trace elements and vitamins under the guidance of a doctor. If you have any concerns, please consult a relevant healthcare professional.
