The Link Between Oral Health and Overall Health
How Periodontal Disease Affects Your Overall Health
Periodontal (gum) disease is not just a condition of the mouth — it is a chronic inflammatory disease that can influence your entire body. Research continues to show strong links between gum health and systemic health.
Healthy gums support a healthy body.
Explore how periodontal disease impacts different areas of your overall health below, including heart disease, diabetes, and more:
What Is Periodontal Disease?
Periodontal disease is a chronic infection and inflammation of the gums and supporting bone around the teeth. It begins as gingivitis (bleeding, swollen gums) and can progress to periodontitis, where bone loss and tooth mobility occur.
When gums are inflamed, bacteria and inflammatory mediators can enter the bloodstream — contributing to inflammation elsewhere in the body.
Cardiovascular Disease
Studies have shown an association between periodontal disease and:
- Heart disease
- Stroke
- Atherosclerosis (narrowing of arteries)
Statistics:
- Greater than 43% of Canadians have undiagnosed hypertension
- Active periodontal disease patients have a 50% increased risk of heart disease and a 30% increased risk of stroke
- 50% of heart attacks are triggered by infection in the mouth
- Periodontal disease increases heart attack risk by 84%, independent of other risk factors
- Regular dental cleanings reduce stroke risk by 50%
Oral bacteria have been found in arterial plaques, suggesting gum inflammation may contribute to vascular inflammation and clot formation.
Diabetes
The relationship between periodontal disease and diabetes is bidirectional:
- Poorly controlled diabetes increases the risk and severity of gum disease
- Severe gum disease can make blood sugar more difficult to control
- 86% higher risk of gum disease progressing with diabetes
- Periodontal treatment can reduce A1C by 0.4%
- If A1C is above 7.0, patients should be coming for cleanings every 3 months
Treating periodontal disease has been shown to improve glycemic control in some patients.
Pregnancy
- Preterm birth
- Low birth weight
- Increased inflammatory burden during pregnancy
- Gestational diabetes increases the risk of developing type 2 diabetes by 8x
Maintaining gum health is an important part of prenatal care.
Respiratory Conditions
- Pneumonia
- Chronic obstructive pulmonary disease (COPD) complications
This risk is higher in elderly patients and those with compromised immunity.
Cognitive Health
Emerging research suggests chronic inflammation from periodontal disease may be associated with cognitive decline and increased risk of conditions such as dementia. While research is ongoing, inflammation is a key factor in many neurodegenerative diseases.
Recent statistics:
- Periodontal disease doubles your risk for Alzheimer’s disease
- Cognitive decline happens 6% faster with periodontal disease
- Good oral health decreases cognitive decline
Osteoporosis
Chronic Inflammation & Immune Burden
- Autoimmune disorders
- Metabolic syndrome
- Certain cancers
Reducing oral inflammation helps reduce systemic inflammatory stress.
Why This Matters
Periodontal disease is often painless in its early stages. Bleeding gums are not “normal” — they are a sign of inflammation.
Early detection and treatment can:
- Reduce tooth loss
- Improve systemic health markers
- Lower overall inflammatory burden
- Support long-term wellness
Protecting Your Oral & Systemic Health
- Brush twice daily with fluoridated toothpaste
- Floss or use interdental cleaners daily
- Attend regular hygiene appointments
- Complete recommended periodontal therapy
- Maintain good control of systemic conditions (e.g., diabetes)
