Pulp therapy is also called “children’s root canal,” “nerve treatment,” “pulpotomy,” or “pulpectomy.” The pulp of a tooth is the inner core that contains nerves, blood vessels, and connective tissue. When a child has a severe cavity or a tooth injury, pulp therapy can be used to remove the damaged pulp and seal the tooth to prevent further problems. A pulpotomy removes the diseased pulp within the crown (top) of the tooth and uses an agent to prevent bacterial growth and calm the nerve tissue. The tooth is then capped with a crown. A pulpectomy is a more extensive treatment that removes all the pulp tissue from both the crown and the root. The canals are then cleansed and filled before being capped.
