Pulpitis needs to be treated as soon as possible. If pulpitis is not treated in time, it will worsen, and bacteria will further infect, reaching the apical area and causing apical periodontitis. Severe apical periodontitis may involve destructive resorption of the apical area and the alveolar bone, and inflammation may discharge pus through the mucous membrane or skin. Clinically, symptoms such as abscesses or space infections may occur, which is quite severe and can even cause systemic septicemia. Therefore, pulpitis needs to be treated as soon as possible. The treatment of pulpitis involves removing the infected dental nerve, medicating the root canal, and performing root canal filling, that is, a complete root canal treatment.
