What should I do if my child has a sore mouth and oral ulcers?

When a child develops mouth ulcers causing oral pain, consider the following methods for relief and treatment: 1. Topical medication: Use oral ulcer treatments suitable for children, such as Xisuangshuang or Yunnan Baiyao, applied directly to the affected area to help reduce inflammation, relieve pain, and promote healing. 2. Nutritional supplementation: Ensure the child receives sufficient vitamin C and B-complex vitamins, which are essential for maintaining healthy oral mucosa. Encourage the child to eat more fresh vegetables and fruits to obtain necessary nutrients. 3. Avoid irritants: Prevent the child from consuming spicy or irritating foods to minimize irritation to the oral mucosa and alleviate pain. 4. Maintain oral hygiene: Teach the child proper tooth brushing techniques and emphasize good oral hygiene to prevent bacterial growth and worsening of the ulcers. If ulcer symptoms persist or worsen, seek medical attention promptly.
