Pulpitis should not be treated by extraction. Pulpitis is simply a painful response caused by an infection of the pulp tissue and can be managed by preserving the tooth through root canal treatment. First, drill to remove the infected dental tissue, and when the dental nerve is exposed, apply a nerve-killing medication. After the nerve is destroyed, thoroughly remove the infected tissue, then seal the root canal, and after inflammation is controlled, fill the root canal. With treatment, it is possible to preserve teeth with pulpitis and extraction should not be performed. Removing a tooth during an active episode of pulpitis may lead to the systemic spread of inflammation.
