What should be done if a child has severe mouth ulcers?

When a child suffers from severe oral ulcers, parents should take a series of measures to alleviate pain and promote healing. 1. Ensure the child receives sufficient vitamins and trace elements, especially vitamins B and C, as well as zinc and iron, which help strengthen the immune system and reduce the occurrence of ulcers. 2. For the ulcerated areas, medications with anti-inflammatory, analgesic, and healing properties, such as watermelon frost or Yunnan Baiyao, can be applied directly to the affected site multiple times daily to accelerate healing. 3. Regarding diet, encourage the child to drink plenty of water and consume more fresh fruits and vegetables, while avoiding fried, spicy, and smoked foods to minimize irritation to the oral mucosa. Additionally, maintain good oral hygiene by brushing teeth morning and night, and rinsing the mouth with mild salt water after meals to reduce bacterial growth. Moreover, parents should also pay attention to the child's mental state, avoiding emotional factors such as excessive excitement or anxiety, which may trigger oral ulcers.
