Gingivae

The gingivae are also known as the gums.
("Gums" is the colloquial term used in everyday English whereas "gingivae" is the anatomical term used in medical textbooks, research papers and other documents.)

The gingivae are the ridges of oral mucosa located at and surrounding the base of each tooth and so forming two continuous "gingivae", one attached to the upper-jaw and the other attached to the lower-jaw (upper jaw bones = maxillae; lower jaw bone = mandible).

The word gingivae is plural so correct for referring to both of the two gingivae.
The singular word is gingiva. Most people have both an upper gingiva and a lower gingiva.

Other words derived from gingiva / gingivae include:

• gingivitis - meaning inflammation of the gingivae
• gingivectomy - meaning the surgical removal of excess gum tissue.

The gingivae (also known as the gums) are among the structures in the human oral cavity. See also the links to pages about other parts of the mouth.
