The gingival sulcus is an area of potential space between a tooth and the surrounding gingival tissue and is lined by sulcular epithelium. The depth of the sulcus (Latin for groove) is bounded by two entities: apically by the gingival fibers of the connective tissue attachment and coronally by the free gingival margin. [ ]

Synonyms: gingival sulcus sulcus gingivalis tooth-gingiva interface
