This small cord is called a retraction cord. The dentist uses a retraction cord packer to place the cord around the gum line during a crown procedure because it eliminates blood from surrounding the tooth during the preparation. This allows the dentist to see the margins of the tooth as well as to take a perfect impression for the permanent crown.
