Are You Aware of The Connection Between Oral Health and Cardiovascular Disease?

Beyond the conventional perception of oral care as confined to the teeth and gums, a growing body of evidence suggests that one's oral health serves as a window to broader systemic health. In particular, the link between oral health issues and cardiovascular disease has become a focal point of investigation. This emerging understanding underscores the interconnected nature of bodily systems, emphasizing the profound impact oral health can have on heart health.

Understanding Oral Health and Its Systemic Impact

Oral hygiene refers to preventive practices, such as brushing and flossing, that keep the mouth clean and disease-free. Maintaining good oral hygiene prevents the development of cavities, gum disease, and bad breath. However, a lesser-known fact is that oral health is directly related to systemic health. Oral infections and inflammation have been associated with endocarditis, cardiovascular disease, pregnancy complications, pneumonia, and Alzheimer's disease. Scientific research has increasingly highlighted the interconnectedness between chronic inflammation in the oral cavity and systemic inflammation – setting the stage for the development or exacerbation of various health conditions. (4

This connection emphasizes the importance of viewing oral health as integral to holistic wellness. Neglecting oral hygiene not only poses risks to the teeth and gums but can also have far-reaching consequences for systemic health. Recognizing the intricate relationship between oral health and the rest of the body underscores the need for comprehensive healthcare strategies that encompass both dental and general well-being. 

What is Periodontal Disease?

Periodontal disease, commonly known as gum disease, is a chronic inflammatory condition affecting the tissues and bones surrounding and supporting the teeth. Microbial dysbiosis of the commensal oral bacteria is responsible for initiating and propagating disease. As pathogenic bacteria colonize the tissue surrounding the tooth, they cause inflammation and form a film called plaque. If not adequately removed through regular oral hygiene practices, plaque can harden into tartar, leading to periodontal disease. (5)

Gingivitis is the earliest stage of periodontal disease. Gingivitis presents with red, swollen gums that may bleed. As periodontal disease advances to periodontitis, the gums can pull away from the tooth, bone loss may occur, and teeth may fall out. (15

The prevalence of gum disease is a significant concern in dentistry, affecting a substantial portion of the global population. According to the CDC, 47.2% of adults aged 30 and older have some form of periodontal disease. Periodontal disease increases with age and is more common in men than women. The prevalence is influenced by factors such as genetics and lifestyle habits, including smoking and poor oral hygiene. (15

Beyond its impact on oral health, the prevalence of gum disease has broader implications for overall well-being. Emerging research suggests a potential connection between periodontal disease and systemic conditions such as diabetes, heart disease, respiratory disease, cancer, Alzheimer's disease, and adverse pregnancy outcomes. The chronic inflammation associated with gum disease may contribute to systemic inflammation, influencing various organs and systems. Consequently, understanding what periodontal disease entails and its prevalence underscores the importance of comprehensive oral care for maintaining a healthy smile, preserving overall health, and preventing potential systemic repercussions. (5, 9

Linking Oral Health to Cardiovascular Disease

In recent years, a growing body of research has explored the intricate relationship between poor oral health, particularly periodontal disease, and an elevated risk of cardiovascular disease. Numerous studies have indicated that individuals with untreated periodontal disease may face a two to three-times increased likelihood of developing atherosclerotic cardiovascular disease (ASCVD) and having a heart attack or stroke. 

Data from the National Health and Nutrition Examination Survey (NHANES) and systematic reviews support a positive association between elevated blood pressure (hypertension) and severe periodontal disease. Furthermore, research has found that patients with coexisting hypertension and periodontal disease were less likely to respond to anti-hypertensive medications and 20% less likely to achieve goal blood pressure readings. (6

Periodontal disease impacts cholesterol patterns, promoting lipid profiles that elevate the risk of ASCVD. A 2017 meta-analysis noted an association between periodontal disease and elevated levels of LDL cholesterol and triglycerides and lower levels of HDL cholesterol. Patients with periodontal disease are also reported to exhibit smaller, denser LDL particles that are more atherogenic compared to those without.

Periodontal disease could contribute to insulin resistance, with research indicating positive associations between gum disease, elevated blood sugar levels, and impaired glucose tolerance. This perpetuates a vicious cycle, as hyperglycemia fosters the proliferation of bacteria responsible for causing periodontal disease. (5

One key mechanism linking oral and heart health revolves around chronic inflammation. Periodontal disease is characterized by persistent inflammation of the gums and surrounding tissues, driven by the immune system's response to bacterial infection. Patients with periodontal disease have measurable elevations in inflammatory markers, including C-reactive protein (CRP) and interleukins. Elevations in CRP are implicated in the development and progression of cardiovascular diseases, increasing the risk of major cardiovascular events. (5

Bacterial dissemination from the oral cavity to other body parts is another potential mechanism in this complex interplay. Once in circulation, the bacteria that infect the gums may cause blood vessel inflammation and damage as they travel to blood vessels throughout the body. This increases the risk of atherosclerosis, blood clots, heart attack, and stroke. This theory has been supported by isolating remnants of oral bacteria within atherosclerotic plaques. (17

Functional Medicine Testing for Oral-Cardiovascular Health 

Functional medicine lab testing emerges as a valuable tool for assessing risks associated with both oral and cardiovascular health. These tests delve beyond traditional diagnostics, providing a comprehensive view of the body's interconnected systems. Beyond merely identifying oral health issues, these tests enable a deeper exploration of the impact oral conditions may have on systemic health, particularly regarding inflammation and cardiovascular risk factors. 

C-Reactive Protein (CRP)

CRP is a protein made by the liver in the presence of inflammation. Elevated CRP levels have been associated with both periodontal disease and cardiovascular conditions. The "high-sensitivity" version of the test (hs-CRP) is more precise and can detect lower levels of CRP in the blood, making it a more sensitive indicator of inflammation.

Lipid Profiles

The link between periodontal disease and alterations in lipid profiles underscores the intricate relationship between oral and heart health. An advanced lipid profile provides detailed information about an individual's cholesterol levels beyond the standard panels. These tests can assess the size and density of cholesterol-carrying particles, providing a more accurate assessment of cardiovascular risk. They can also include other predictive markers for cardiovascular outcomes, such as Apo-B, oxidized LDL, and homocysteine

Diabetes Panel

The Diabetes Panel by Vibrant America includes various tests to evaluate glucose metabolism and tolerance. Markers, including fasting insulin, fasting glucose, and hemoglobin A1c, are valuable in screening for insulin resistance, elevated blood sugar, and diabetes.

Preventive Measures and Oral Hygiene Practices

Adopting a proactive oral hygiene approach is paramount to protecting oral and cardiovascular health. Regular biannual dental check-ups prevent periodontal disease and maintain optimal oral health. These visits allow for professional cleanings, plaque and tartar removal, and early detection of potential issues. Dentists can assess gum health, address concerns promptly, and provide personalized advice on oral hygiene practices. Functional dentists are trained in holistic healthcare and go beyond traditional dentistry's focus on solely treating dental issues. Functional dentistry considers the interconnectedness of various bodily systems and how they relate to oral health, and vice versa.

At-home oral hygiene practices form the foundation of preventing periodontal disease and fostering heart health. Brushing teeth at least twice daily helps remove plaque and prevent the onset of gum disease. Flossing daily is equally crucial, as it eliminates debris and bacteria from between teeth and along the gumline, areas often missed by brushing alone. (19

Maintaining a well-balanced diet and limiting sugary snacks can positively impact oral and heart health. Instead, focus on eating a heart-healthy diet rich in fruits, vegetables, whole grains, legumes, nuts, seeds, lean proteins, and healthy fats to support oral and cardiovascular health. (14

Diagnosis and Monitoring: Role of Healthcare Professionals

The collaborative efforts of dental and medical professionals play a pivotal role in diagnosing and monitoring oral health conditions, with a keen awareness of their potential impact on heart health. Diagnosing periodontal disease requires a multifaceted approach, often involving both dentists and medical practitioners. Dental professionals employ clinical assessments, dental imaging, and probing techniques to identify the presence and severity of periodontal disease, while other medical professionals may utilize diagnostic tools to assess systemic markers and potential cardiovascular implications.

An interdisciplinary approach is crucial in managing these linked health concerns, recognizing the intricate relationship between oral and heart health. Regular communication and collaboration between dentists and physicians enable a holistic understanding of the patient's health profile, facilitating early detection and intervention for both oral and cardiovascular issues.

Treatment Strategies for Periodontal Disease

In early cases of periodontal disease, treatment typically involves non-surgical interventions, including the following:

  • Scaling and Root Planing: This is a standard non-surgical procedure for treating periodontal disease. It involves thoroughly cleaning the tooth surfaces and removing plaque and tartar from above and below the gumline. Root planing smoothes the tooth roots to prevent further bacterial buildup.
  • Antibiotics: In some cases, antibiotics may be prescribed to control bacterial infection. This can be in the form of oral antibiotics or, more locally, as an antimicrobial rinse or gel applied directly to the affected areas. Antimicrobial mouthwashes may also be recommended to reduce the bacterial load in the mouth. (16)

Advanced cases of periodontitis may require surgical interventions. Flap surgery, or pocket reduction surgery, is a procedure in which the gums are cut and folded back to remove tartar deposits and reduce pocket depth. When severe periodontitis leads to gum recession and bone loss around the teeth, bone and tissue grafts may required to reinforce damaged tissues and stabilize the teeth. (16

Lifestyle Modifications and Risk Factor Management 

Lifestyle changes are instrumental in promoting optimal oral health and cardiovascular well-being. Adopting a healthy lifestyle, which includes maintaining a nutritious diet, engaging in regular physical activity, and getting adequate sleep, can lower the risk of developing cardiovascular disease. Effectively managing underlying medical conditions, such as high blood pressure, elevated cholesterol levels, and diabetes, can further contribute to mitigating the risk of cardiovascular disease and related events. (11

Smoking cessation is critical for reducing the risk of periodontal disease but also significantly reduces cardiovascular disease. Smoking doubles the risk for gum disease and causes 25% of deaths due to cardiovascular disease. Quitting smoking lowers inflammation, improves blood circulation, and strengthens the immune system – fostering a healthier environment for the gums and the heart. (2, 18)

Effective stress management promotes a healthier lifestyle and positively impacts oral and cardiovascular health. Chronic stress has been linked to the exacerbation of periodontal disease and an increased risk of heart problems. Incorporating relaxation techniques, such as mindfulness or yoga, can mitigate stress levels, promoting a harmonious balance that benefits both the oral cavity and the cardiovascular system. (10, 12

Scientific evidence suggests a significant interconnection between oral and heart health, emphasizing the importance of maintaining good oral hygiene. Regular dental check-ups, coupled with collaborative efforts between healthcare professionals and healthy lifestyle habits, play a crucial role in the early detection and holistic management of potential risk factors. Recognizing the reciprocal relationship between oral and cardiovascular health helps individuals to prevent and treat disease holistically.
