Causes of Gingival Recession

As people age, gingival recession commonly occurs—i.e., the gums gradually recede, exposing a small portion of the tooth root—a natural, physiological phenomenon. However, some individuals experience gingival recession at a relatively young age, often due to periodontitis. Periodontitis causes widening of interdental spaces and progressive gum tissue loss; severe gingival recession may ultimately lead to tooth loss, necessitating prompt periodontal treatment to prevent such complications.

Causes of Gingival Recession

Gingival recession is a common condition primarily caused by periodontal disease. Subgingival dental calculus (tartar) accumulates at the base of the gums and contributes to gingival recession and eventual tooth mobility or loss. Gingival recession is broadly classified into two types: pathological and physiological. Pathological recession typically results from persistent accumulation of irritants—especially dental calculus—at the gingival margin, leading to chronic bacterial infection and inflammation. Physiological recession, on the other hand, occurs gradually with aging and involves mild, natural exposure of the tooth root surface. Periodontitis is one of the primary causes of gingival recession. It induces inflammatory destruction of the supporting structures around teeth—including alveolar bone resorption—which in turn compromises the attachment of gingival tissue to the underlying bone, resulting in visible gingival recession.

Treatment Options for Gingival Recession

1. Maintain Optimal Oral Hygiene

Use toothpaste and toothbrushes that meet national safety and quality standards. Brush teeth two to three times daily, with brushing before bedtime being essential. When brushing is not feasible or convenient, rinsing with mouthwash serves as an effective alternative. In certain situations, rinsing with soup or tea may also help maintain oral cleanliness.

2. Schedule Regular Professional Dental Care

Professional dental cleaning (scaling and polishing) every six to twelve months is an effective preventive measure against gingivitis and early-stage periodontitis. Patients already exhibiting signs or symptoms of periodontal disease should seek comprehensive, systematic periodontal therapy without delay.

3. Adopt Proper Brushing Techniques

Select a soft-bristled toothbrush with rounded bristle tips. Fluoride-containing toothpaste is recommended; its abrasive particles should be of appropriate fineness—neither too coarse nor too fine. Overly stiff brushes, overly abrasive toothpastes, or incorrect brushing techniques (e.g., excessive lateral pressure or horizontal scrubbing) can all contribute to gingival recession.

Other systemic factors may also predispose individuals to gingival recession—for example, endocrine disorders, anemia, vitamin C deficiency (which increases susceptibility to gingival bleeding), diabetes mellitus (associated with higher risk of oral infections), and serious systemic conditions such as leukemia.

Regular dental examinations and consistent adherence to sound oral hygiene practices are key to preventing periodontitis—and thus avoiding gingival recession. Once recession has occurred, surgical interventions (e.g., gingival grafting) may be required. Additionally, routine gentle gum massage and increased dietary intake of high-fiber foods may support gingival health and help prevent further recession.
