Gingival retraction or gingival recession is when there is lateral movement of the gingival margin away from the tooth surface. [1] [2] It is usually termed gingival retraction as an intentional procedure, and in such cases it is performed by mechanical, chemical, or electrical means in order to perform certain dental surgery procedures.
1: Total loss of attachment (clinical attachment loss, CAL) is the sum of 2: Gingival recession, and 3: Probing depth. Gingival recession, also known as gum recession and receding gums, is the exposure in the roots of the teeth caused by a loss of gum tissue and/or retraction of the gingival margin from the crown of the teeth.

Gingival recession is when there is an apical movement of the gum margin away from the biting (occlusal) surface. [4] It may indicate an underlying inflammation such as periodontitis [ 5 ] or pyorrhea , [ 5 ] a pocket formation, dry mouth [ 5 ] or displacement of the marginal gums away from the tooth by mechanical (such as brushing), [ 5 ...
The epithelial attachment does not migrate, it simply remains at the same attachment level found in pre-pathological health. The only anatomical landmark experiencing migration is the gingival margin in a coronal direction. In a gingival pocket, no destruction of the connective tissue fibers (gingival fibers) or alveolar bone occurs.
Plaque tends to build up around the gingival margin (the gumline) and in gingival crevices or periodontal pocket (below the gumline). The release of waste products from the bacteria living in the biofilm causes an inflammatory response in the gums which become red and swollen, bleeding easily when disturbed.
In dental anatomy, 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.
Healthy gingiva can be described as stippled, pale or coral pink in Caucasian people, with various degrees of pigmentation in other races. The gingival margin is located at the cemento-enamel junction without the presence of pathology. The gingival pocket between the tooth and the gingival should be no deeper than 1–3mm to be considered ...
The vertical dimension between the implant platform and the gingival margin is termed running room. In implant dentistry , running room refers to the apico-coronal distance between the platform of a dental implant and the gingival margin .
