The obvious benefit is that the tooth is maintained in service and holds the space for the developing permanent tooth below it. The disadvantages are teeth that receive nerve treatments likely require a crown (silver cap) to be placed on the tooth to provide adequate strength. Occasionally, the bacteria invade the nerve completely and a pulpotomy fails and the tooth must be removed, but the risk is low.
