How to treat four mouth ulcers?

When four ulcers develop in the mouth, treatment should involve a comprehensive approach. 1. General management includes drinking plenty of water and consuming fruits and vegetables rich in vitamin C, such as apples and oranges, to promote ulcer healing. It is also important to maintain good oral hygiene by brushing teeth morning and night and rinsing the mouth after meals to prevent food debris accumulation. 2. Physical therapies, such as cold or warm compresses, may help relieve pain caused by ulcers. Additionally, medication plays an important role in treatment. Topical agents like oral ulcer powder or Guilin Watermelon Frost can reduce pain and accelerate healing. For significant pain, medications such as compound benzocaine gel or lidocaine hydrochloride gel may be used to provide pain relief. 3. Patients should avoid excessively hot, acidic, spicy, or irritating foods, and maintain healthy eating habits and regular作息 (daily routines) to prevent worsening of symptoms.
