Pulpitis is a possible cause of tooth pain, which is usually caused by the presence of cavities in the tooth. The main symptom of pulpitis is spontaneous paroxysmal pain, which is also accompanied by hot and cold stimulation pain, night pain and so on. If the tooth has paroxysmal pain, it is necessary to go to the hospital for root canal treatment in time. The nerve of the tooth is removed and the root of the tooth is treated thoroughly so that the tooth pain caused by pulpitis can be completely resolved. After the root canal treatment, the tooth will be filled or crowned so that the tooth can remain in the mouth and continue to perform its chewing function. Pulpitis is usually caused by the progress of caries, once the caries appears, you should go to the hospital in time to do the filling treatment, so that the caries can be controlled in the early stage, so that it will not continue to develop, if the caries is not paid attention to, then it will continue to destroy the tooth, and the destruction of the pulp will form pulpitis, which will lead to the tooth pain. For pulpitis, you must not rely on medicine to treat it, but must go to a regular hospital or clinic to do root canal treatment, so as to completely treat the toothache caused by pulpitis.
