What should be done if a child develops a mouth ulcer on the tongue?

When a child develops oral ulcers on the tongue, parents can take several measures to help alleviate the child's discomfort and promote ulcer healing. It is recommended that parents promptly take the child to the hospital for medical evaluation, to determine the specific cause of the ulcer and obtain professional treatment advice. Treatment of oral ulcers can be approached in the following ways: 1. Dietary adjustment: Encourage the child to consume foods rich in vitamins and trace elements, such as vegetables, fruits, and lean meats. Avoid spicy and irritating foods to reduce irritation to the ulcerated area. 2. Topical medications: Under a doctor's guidance, apply medications such as oral ulcer powder or Bingpeng powder directly onto the ulcerated area to help relieve pain and promote healing. 3. Oral medications: If the ulcer is severe, take vitamin C tablets or compound vitamin B tablets orally as directed by a physician, to supplement necessary nutrients and promote ulcer healing. 4. Physical therapy: Treatments such as laser therapy or microwave therapy may be performed under a doctor's supervision, which can help accelerate inflammation resolution and ulcer healing.
