A pulpectomy specifically involves the complete removal of vital pulp from a tooth. This procedure is typically performed in cases where the pulp has become inflamed or infected but the tooth is still considered salvageable. During a pulpectomy, the dentist or dental assistant removes all of the pulp tissue, which includes nerves and blood vessels, to eliminate the source of pain and infection. After the pulp is removed, the empty space within the tooth is usually cleaned and filled to prevent further microbial invasion.

The other options do not accurately describe a pulpectomy. Filling a cavity pertains to restorative procedures focused on surface decay, while a tooth extraction involves the complete removal of the tooth itself, and placing a crown is a procedure aimed at restoring a tooth’s structure and function after treatment, typically following root canal therapy or a similar procedure.
