The treatment of root canal inflammation mainly includes medication, surgery and physical therapy. 1. Medication: Under the guidance of a professional doctor and in combination with personal conditions, patients can use a combination of drugs such as metronidazole tablets, cefadroxil capsules and ibuprofen extended-release capsules, which can effectively alleviate and improve the discomfort of patients with radiculitis. 2. Surgery: Root canal treatment is the first choice for root canal treatment. Depending on the development of the patient’s condition, the patient can also choose to use pulpal hemotransplantation, microscopic apical surgery, and tooth extraction and other surgical procedures to carry out the treatment. 3. Physical therapy: If the patient is still not cured after several root canal surgeries, physical means such as ultrasound, laser, sonic wave or negative pressure technology can also be chosen for treatment. Root infection patients should strictly follow the doctor’s prescription of medication, to avoid blind use of medication to cause adverse effects. If root infections are treated in a timely manner, the affected tooth can usually be preserved and the prognosis is good, so the patient does not need to worry too much.
