Gingival retraction refers to the displacement of the free gingivae. Areas normally affected are lips, buccal mucosa, gingivae, frenum and tongue. The most common injuries are lips and gingivae. The most common is chronic inflammatory gingival enlargement, when the gingivae are soft and discolored. The gingivae are categorised into three anatomical groups; the free, attached and the interdental gingiva. Gingivae lacerations that are small normally heals spontaneously and do not require any intervention.
