What is gingiva (gum) and its function?
The gingiva (gum) is the protective type of skin that is closely adapted to the necks of the teeth and covers the bone holding the roots of the teeth. There is a shallow ditch like space that separates the margin of the normal gingiva from the tooth surface. This space is 2mm in depth and is called gingival sulcus. It is one of the places that a dentist will carefully examine to detect the presence of gum disease.
