The benefits of dental care go far beyond just a healthy mouth. For years we have been aware of the links between oral health and various aspects of overall health. Recent research has confirmed previously suspected links between periodontitis (severe gum disease), stroke, and Alzheimer’s disease, as well as other systemic health concerns. In this article, we give a brief overview of the current understanding of all these interconnections between overall health and oral health, adding authority to the fact that maintaining good oral health and seeking regular professional dental care is one of the best ways to ensure long lasting overall health.
- Periodontitis and stroke
Some studies have suggested a correlation between periodontitis and an increased risk of stroke. Inflammation associated with severe gum disease may contribute to systemic inflammation, which, in turn, can affect blood vessels and increase the risk of cardiovascular problems, including stroke. These findings are cited in Periodontal Disease, Regular Dental Care Use, and Incident Ischemic Stroke (2018).
- Gum disease and Alzheimer’s disease
Inflammation is considered a factor in the pathogenesis of Alzheimer’s disease, and some studies have found associations between poor oral health and cognitive decline. There is ongoing research exploring the potential link between periodontitis and Alzheimer’s disease, most recently in Are Periodontitis, Stroke, and Alzheimer’s Disease Linked? (2023), which confirms that gum disease is strongly linked to neurological diseases such as strokes and Alzheimer’s. Previously, heart conditions, high blood pressure, and diabetes were linked, and now we understand just how strongly they are associated.
- Oral health and systemic health: dental care is holistic health care
Oral health is connected to systemic health. Conditions like periodontitis can have effects beyond the oral cavity, potentially impacting other parts of the body.
Systemic Inflammation: Periodontal (gum) disease causes chronic inflammation of the gums. This triggers an immune response in the body which can lead to systemic inflammation. If persistent, this inflammatory response can exacerbate many systemic diseases.
