What is the role of free gingival fibers?

The role of free gingival fibers is crucial in maintaining the structure and functionality of the gums surrounding each tooth. These fibers are connective tissue structures located in the marginal gingiva and are oriented horizontally and slightly obliquely to the tooth surface. Their primary function is to help secure the gingival tissue to the tooth, forming a cuff-like structure that surrounds the tooth. This cuff is essential for creating a barrier against bacteria and contributing to periodontal health.

By supporting the attachment of the gingival tissue, free gingival fibers help to maintain the integrity of the gingival margin, which is important for preventing periodontal disease. A well-maintained gingival cuff aids in keeping the gums tightly against the teeth, reducing the risk of inflammation and infection. Thus, this role of maintaining the gingival cuff around each tooth is vital for overall oral health.
