gingiva(e)

(jin´jivə),
n/n.pl the fibrous tissue that immediately surrounds the teeth. Colloquial term is gums.
gingiva, adequate attached (AAG),
n the amount of attached gingival tissues needed to prevent recession of the gingival tissues.
gingivae, attached,
n the portion of the gingivae extending from the free gingival groove, which demarcates it from the marginal (free) gingivae, to the mucogingival junction, which separates it from the alveolar mucosa. This tissue is firm, dense, stippled, and tightly bound down to the underlying periosteum, tooth, and bone.
gingivae, attached, extension,
gingiva, detached by calculus,
n the recession and ultimate disconnection of gingival tissue from tooth sur-faces that occurs as the result of the presence of large amounts of calculus.

gingivae, erythemic
n.pl the unusually red gingival tissue that may be caused by either inflammation or excessive blood in the tissue. The condition may occur as a result of excess vitamin A.
gingivae, free,
n.pl an older term for the unattached coronal portion of the gingiva that encircles the tooth to form the gingival sulcus. More commonly called marginal gingiva.
gingivae hyperplasia,
gingiva, inadequate attached (IAG),
n a condition in which the amount of attached gingival tissues in a surveyed area is less than 1 mm, which may result in gingival recession and other periodontal conditions.
gingiva, interdental,
n (interproximal gingiva[e]), the soft supporting gingival tissue, consisting of prominent horizontal collagen fibers, that normally fills the space between two contacting teeth.

n See gingiva, interdental.
gingiva, lymphatic drainage of,
n the lymphatic drainage that follows the course of the gingival blood supply; i.e., from the lymphatic vessels on the gingival side of the periosteum of the alveolar process to the lymphatic vessels in the periodontal membrane to vessels connecting into the alveolar bone.
gingiva, marginal,
n the free gingiva at the labial, buccal, lingual, and palatal aspects of the teeth.
gingivae, microscopic appearance of,
n.pl the stratified squamous epithelium that varies in degree of keratinization and overlies the lamina dura of connective tissue with interspersed blood vessels and nerves. Rete pegs of epithelium project downward into the connective tissue corium, except from the base of sulcular epithelium. The gingival fiber apparatus is also present.

Patient discussion about gingiva

Q. What are the opportunities to restore gums? My gum on the lower jaw gets less and less, opening the roots of my teeth. Is there any technology or recurement to stop it and, hopefully, draw back?

A. Treatment of receding gums start with treating the cause - improving overall oral hygiene, including brushing habits (too powerful brushing may damage the gums), as well as periodic tooth cleaning at the dentist.

More sever situation may necessitate treatments done by a dentist. Consulting one may be wise.
