How to manage severe oral ulcers after radiotherapy?

Severe oral ulcers after radiotherapy can be alleviated through the following measures: 1. Maintain oral hygiene: Rinse the mouth promptly after meals, and brush teeth in the morning and evening. It is recommended to use normal saline or specialized mouthwash, such as compound chlorhexidine mouth rinse, to reduce food residue and bacterial growth. 2. Adjust diet: Maintain a light diet and consume more fresh vegetables and fruits rich in vitamins, such as oranges and bananas. Avoid spicy, excessively hot, or hard foods that may irritate the ulcers. Keep daily water intake between 1500-2000ml to maintain oral moisture. 3. Timely medication: Follow medical advice to use medications that promote ulcer healing, such as Kangfuxin Solution (recombinant human epidermal growth factor) or Bingboran Powder. Painkillers such as ibuprofen sustained-release capsules may be used in cases of significant pain. Antibiotics should be used if bacterial infection occurs. 4. Seek medical treatment: If oral ulcer symptoms continue to worsen or show no improvement, seek timely professional medical care and treatment.
