Gingiva indexing devices and methods with various defined red colour regions have a colour grey card or grey card assigned to it for detecting the gingiva status, in particular for producing a gingival restoration. The devices and method comprise an analysis of at least one region of the gingiva status with regard to its shades of red, the position of the shades of red, the colour profile of the shades of red, their geometry and/or their morphology. The analysis can take place manually and/or digitally, and gingiva information is obtained, in particular in the form of a gingiva map, and optional production of a virtual or real model of a gingival restoration as a reproduction of the missing part of the gums and/or part of gingiva.
