ABSTRACT:
The specification discloses a gingival retraction cord having a tapered diameter throughout its length and having a length sufficient to enable the cord to be wrapped several times about a tooth. In use, the cord, starting with its smaller end, is spirally wrapped and packed about a tooth between the tooth and surrounding gingival tissue to form a flared gingival crevice.
