During an acute episode of pulpitis, patients experience very severe spontaneous pain, paroxysmal sharp pain, and pain from hot and cold stimuli, which sometimes radiates to the head and intensifies at night. Medication for pulpitis is ineffective, as anti-inflammatory drugs only address the symptoms and not the root cause. In such cases, it is essential to visit a hospital, where a dentist can perform a pulpectomy, conduct root canal treatment, thoroughly treat the inflamed pulp, remove the infected dentin, apply medication inside the root canal, and then seal and fill the root canal tightly. Only through comprehensive root canal treatment can pulpitis be completely cured.
