Depends. Pulpitis means inflammation of the tooth pulp (nerve) causing tooth to hurt. It can be reversible or irreversible. Reversible pulpitis can be eliminated by removing the cause. Adjusting a new filling/crown that is too high or wearing a night guard to prevent grinding will stop pulpitis. Irreversible pulpitis is when the pulp is too sick to heal itself and a root canal or extraction is required.
