How to deal with tooth cavity nerve pain

Tooth nerve pain caused by a cavity is a common symptom of severe dental problems and requires immediate attention. You can try applying a cold compress by wrapping ice in a towel and placing it on the affected side of the face to alleviate localized pain. If the pain is severe, it is recommended to seek medical advice promptly, and take pain relievers such as ibuprofen sustained-release tablets or diclofenac sodium sustained-release capsules orally under a doctor's guidance. For definitive treatment of tooth nerve pain, root canal therapy is generally required to thoroughly remove the infection, disinfect, and fill the root canal to eliminate pain. During the treatment period, it is important to strictly follow medical instructions and maintain good oral hygiene habits to promote recovery.
