How is the width of attached gingiva related to periodontal health?

The width of attached gingiva plays a significant role in maintaining periodontal health, primarily by minimizing the risk of gingival recession. Attached gingiva is the area of gum tissue that is tightly bound to the underlying alveolar bone and is essential for providing stability to the gingival margin. A sufficient width of attached gingiva helps to protect the periodontal tissues from mechanical forces caused by oral hygiene practices, such as brushing and flossing.

When there is an adequate amount of attached gingiva, it creates a buffer against the irritation or trauma that can lead to inflammation and loss of the gingival attachment. A narrow band of attached gingiva may be more susceptible to recession because the underlying tissues lack adequate protection. This could ultimately lead to exposure of the roots of the teeth, sensitivity, and increased vulnerability to periodontal disease.

The other options do not accurately reflect the relationship between the width of attached gingiva and periodontal health. For instance, while adequate gingival tissue contributes to overall oral health, it does not specifically prevent cavities around teeth. Cosmetic appearance may be enhanced by healthy gingival tissue, but that is not its primary role in periodontal health. Suggesting that it has no impact on periodontal health overlooks its critical function in protecting and supporting the periodontal structures.
