Gum (gingiva) is part of the attachment apparatus of the teeth and is comprised of soft connective mucosal tissues. Gum is covered by alveolar bone of both jaws and tooth necks. Away from the teeth downwards passes into the mucosa lining the oral cavity, the transition between the mucous membranes is called mucogingival line.

We can talk about more types of gum according to their location:

• Free marginal gingiva – it is a part, which is bordered tooth
• Connected gum – is the continuation of free gums, not moving against the base is firmly fixed to the periosteum (periosteum) of the alveolar bone
• Interdental, interdental, gum – form the interdental papilla, thus filling the space of the gums between the teeth

Healthy gingiva is to be light pink, smooth, if present zarudne inflammation and swell in the case of anemia may be brighter white.
