It is not useful to rinse your mouth with salt water for pulpitis. Salt water rinse has a certain anti-inflammatory and cleaning effect on the mouth, but it is not effective for treating pulpitis. The main symptom of pulpitis is severe pain, which occurs after eating cool or hot food, or after biting into hard food, which causes continuous severe pain. The treatment of pulpitis is clinically based on root canal therapy, where local anesthesia is used to remove the infected decaying tissue from the tooth under local anesthesia, open the pulp chamber and unblock the root canal to release the pressure in the pulp chamber and inactivate the pulp nerve. In addition, the root canal system will be tightly disinfected and filled, and finally the crown will be restored. Root canal therapy is currently the only effective treatment for pulpitis. When pulpitis is particularly painful during the acute phase, you can take pain medications such as ibuprofen or fenpropathrin to relieve the pain, as well as anti-inflammatory drugs such as cephalosporin or metronidazole tablets in moderation.
