If the flesh inside the tooth hurts, it is recommended to go to a professional dentist to see which part of the tooth is causing the pain. The common causes of pain are inflammation and trauma. For pain in the flesh inside the tooth, the most common is the flesh at the very back of the tooth, called the blind pocket of the wisdom tooth, which often causes pain, called pericoronitis of the wisdom tooth. If you have wisdom tooth pericoronitis, the acute phase requires symptomatic treatment, flushing of food debris and bacteria from the blind pocket, and systemic application of antibiotics. Generally, hydrogen peroxide plus saline is used alternately to flush, and systemic antibiotics are generally cephalexin plus metronidazole. The acute inflammatory phase, which is when the patient’s painful period is over, will remove the tooth inside the flesh below the tooth, and most of them can be eradicated.
