A gingival retraction cord having improved characteristics is advantageously constructed by a knitting process. Because of the presence of numerous interlocking loops, the knitted retraction cord is longitudinally elastic, thereby avoiding the tendency to become dislodged once packed as additional portions of the cord are packed around the margin of a tooth. The knitted retraction cord is also transversely resilient, thereby tending to better conform to the gingival sulcus.

A gingival retraction cord comprising at least one strand formed into a plurality of interlocking loops so as to form a knitted retraction cord for use in retracting gingival tissue preparatory to making an impression of a tooth that has been prepared for fitting of an artificial crown, said cord being knitted sufficiently loosely such that it is elastic in its longitudinal dimension so as to be able to be stretched, and resilient in its transverse dimension so as to be able to be compressed and conformed to the contour and shape of a gingival sulcus when being packed therein.
