Editing Gums (section)

===Attached gum===
The attached gums are continuous with the marginal gum. It is firm, resilient, and tightly bound to the underlying periosteum of alveolar bone. The facial aspect of the attached gum extends to the relatively loose and movable [[alveolar mucosa]], from which it is demarcated by the [[mucogingival junction]].  Attached gum may present with [[stippling (dentistry)|surface stippling]]. The tissue when dried is dull, firm, and immobile, with varying amounts of stippling. The width of the attached gum varies according to its location. The width of the attached gum on the facial aspect differs in different areas of the mouth. It is generally greatest in the incisor region (3.5 to 4.5&nbsp;mm in the maxilla and 3.3 to 3.9&nbsp;mm in the mandible) and less in the posterior segments, with the least width in the first premolar area (1.9&nbsp;mm in the maxilla and 1.8&nbsp;mm in the mandible). However, certain levels of attached gum may be necessary for the stability of the underlying root of the tooth.<ref name=":0" />
