Pulpitis should not be treated with tooth extraction. Pulpitis is a type of acute pain caused by bacterial infection of the tooth nerve. During an episode of pulpitis, the pain can be very severe, including dull pain, throbbing pain, and sharp pain. Sometimes cold, hot, sour, or sweet substances can stimulate the tooth nerve, leading to increased nerve pain. Sometimes pulpitis can also radiate to the temporal region, causing headaches or ear pain, and it can sometimes cause pain in both upper and lower teeth and all the teeth. Pulpitis occurs when the dental nerve has become pus-filled due to inflammation. If teeth are extracted rashly, it may lead to the spread of inflammation, causing bacteremia or sepsis. Tooth extraction is not advisable for pulpitis, but root canal treatment can be performed on the affected tooth to try to preserve it after the treatment.
