Factors that affect gum disease

Periodontal (gum) disease is primarily caused by dental plaque—a sticky film of bacteria that forms on teeth.

Without plaque, periodontal disease cannot develop. However, several other factors can influence how quickly gum disease progresses and how severe it becomes.

Often, the presence of multiple risk factors can combine to lower the threshold for the initiation and advancement of disease.

Risk factors

  • While older adults tend to have higher rates of periodontal disease—over 70% of people above age 64 have periodontitis—age itself is not a direct risk factor.

    The increased prevalence in older populations is more likely due to cumulative exposure to other risk factors and longer duration of plaque buildup.

  • Tobacco use is one of the most significant risk factors for the development and progression of periodontal disease.

    Smoking impairs the body’s immune response and healing, making gum tissues more susceptible to infection and slower to recover.

    Smokers may experience up to seven times greater destruction from periodontal disease compared to non-smokers, and the risk increases with the amount smoked.

    Smoking also reduces the effectiveness of periodontal treatments and surgical procedures.

  • Genetic factors play a substantial role in susceptibility to gum disease.

    Studies estimate that up to 50% of people with periodontal disease have a genetic predisposition, which can affect immune response and tissue regeneration.

    Even with excellent oral hygiene, individuals with certain genetic markers may require more intensive maintenance and early intervention to manage their gum health.

  • Chronic stress can negatively impact periodontal health by weakening the immune system and reducing the body’s ability to heal.

    Stressful life events—such as unemployment, marital difficulties, or bereavement—can trigger flare-ups of gum disease.

    tress, especially when combined with poor oral hygiene and smoking, increases the risk of severe forms of gum disease.

  • Certain medications can affect oral health by causing dry mouth, gum overgrowth, or altering the body’s inflammatory response.

    Drugs such as steroids, antidepressants, antihistamines, and some heart medications may increase the risk of gum problems.

    Always inform your dental provider of any changes in your medications or general health.

  • Habitual teeth grinding (bruxism) or jaw clenching can put excessive force on the supporting structures of the teeth, leading to gum recession, tooth mobility, and increased risk of periodontal tissue destruction.

  • Systemic conditions that affect the body’s inflammatory response can worsen gum disease.

    Notably, cardiovascular disease, diabetes, and rheumatoid arthritis are linked to increased risk and severity of periodontal disease.

    Managing these underlying health conditions is important for maintaining optimal gum health.

    Maintaining effective oral hygiene and addressing these risk factors with your dental care provider can help prevent and manage gum disease for a healthier smile and overall wellbeing.

  • A healthy diet is essential for maintaining strong gums and overall oral health.

    When your diet lacks vital nutrients, your immune system can become weakened, making it more difficult for your body to combat infections—including those that affect your gums.

    Since periodontal disease is fundamentally an infection of the gums, poor nutrition can significantly worsen its progression and severity.
