Many patients with pulpitis visit the clinic because of acute pain in the teeth after sleeping at night. The main characteristic of acute pulpitis is pain at night, sometimes waking up with pain after sleeping, which is related to the change in the direction of blood flow in the pulp, so you can change your sleeping position and adopt a side-lying or semi-recumbent position. When toothache occurs, you should go to the emergency dental department for pulpotomy to relieve tooth pain. The main treatment of pulpotomy is to open the pulp cavity with dental instruments under local anesthesia, so that the exudate of the pulp cavity can be drained out of the mouth as much as possible to reduce the pressure of the pulp cavity. In areas where there is no condition, oral pain medication can be taken to relieve pain, such as fen-phen or sulforaphane, but pain medication can only control the pain for a while and cannot cure the pulpal disease. Therefore, it is recommended to consult a dentist and undergo root canal treatment. In particular, it is important to pay attention to regular oral checkups every six months or once a year, so that the doctor can detect the lesion early and treat it early with better results. Once the symptoms of pulpitis are serious, root canal treatment is required afterwards, which takes time, costs more and is not effective.
