Acute inflammation is a key part of the body’s natural healing process. It’s the immune system’s first line of defense, rushing in to handle infections or injuries. But when that inflammation shifts from acute to chronic, it can quietly fuel the development of many serious chronic diseases.
For health practitioners, addressing acute and chronic inflammation in a holistic, functional manner is key to improving patient outcomes, particularly in cardiovascular health. Recent research shows how systemic inflammation— from lifestyle factors to oral health issues—fuels conditions like atherosclerosis. It is vital for us to understand and tackle this issue from multiple angles.
Chronic Inflammation and Cardiovascular Health: A Hidden Threat
Chronic inflammation is at the heart of cardiovascular disease and plays a much bigger role than we used to think. It’s not just a background player but a main driver in conditions like atherosclerosis. The real problem is that inflammation doesn’t stay localized; it is a central player in the progression of heart-related diseases.
Take gum disease, for example—people with it have double the risk of heart disease compared to those without it. That persistent inflammation in the gums can trigger similar processes in the arteries, speeding up plaque formation. What might start in the mouth doesn’t stay there; it can lead to narrowed arteries, restricted blood flow, and, eventually, serious problems like heart attacks or strokes.
As inflammation continues, it leads to endothelial dysfunction. This is key because the endothelium—the inner lining of blood vessels—needs to stay flexible to properly regulate blood pressure. But when it’s inflamed, the whole system becomes rigid and struggles to maintain healthy blood pressure, putting a strain on the heart.
The situation gets even trickier when oxidative stress comes into play. This damages the already inflamed endothelium and creates a cycle of vessel damage, more inflammation, and plaque buildup that the body can’t seem to break.
Chronic inflammation also ramps up blood clotting, which raises the risk of clots blocking blood flow to the heart or brain. In clinical practice, we hear of typical cardiovascular symptoms—fatigue, chest pain, shortness of breath—but the root cause often ties back to chronic low-grade inflammation.
Whether driven by lifestyle factors such as poor diet, high stress, lack of exercise, or environmental toxins, this inflammatory state primes patients for cardiovascular diseases that can develop stealthily over time. For practitioners, identifying and addressing chronic inflammation early on is critical in preventing such outcomes.

The Oral-Systemic Link: Why Oral Health Matters More Than Ever
In recent years, the connection between oral health and systemic inflammation has become a key focus in functional medicine. The mouth, often overlooked in discussions about chronic disease, is a gateway to the body’s overall health. As practitioners, it’s important to recognize the growing body of evidence linking poor oral health with systemic inflammation and heart disease.
Gum diseases like gingivitis and periodontal disease have long been known to cause localized inflammation in the mouth. Research now demonstrates that the inflammatory response doesn’t stay confined to the gums. In fact, the oral microbiome—the ecosystem of bacteria in the mouth—affects systemic inflammation.
When the oral microbiome becomes unbalanced (a condition known as oral dysbiosis), harmful bacteria flourish. These bacteria release toxins and inflammatory molecules that enter the bloodstream and travel far beyond the oral cavity. Once in circulation, these toxins can incite inflammation in distant organs, including the heart.
Oral dysbiosis and gum disease directly contribute to endothelial dysfunction and exacerbate existing cardiovascular conditions. Prioritizing optimal oral health should be an integral part of healthcare plans.
Chronic gum infections can increase C-reactive protein (CRP) levels and trigger an immune response leading to systemic inflammation. As healthcare practitioners, it is essential to educate patients on the importance of maintaining oral health to prevent the worsening of cardiovascular disease.
The Role of the Oral Microbiome in Heart Health
Balancing the oral microbiome isn’t just about reducing gum disease; it’s about preventing the systemic inflammatory cascade that ultimately impacts heart health. The oral microbiome—comprising over 700 species of bacteria—plays a role in this equation. The balance between beneficial and harmful bacteria dictates whether inflammation will remain localized or spread throughout the body.
Probiotic-rich foods and supplements usually used to balance gut microbiota, can also be effective for oral health. Incorporating fermented foods like sauerkraut or miso into a patient’s diet not only supports their gut health but can also influence the oral microbiome.
Polyphenol-rich foods, such as green tea and berries, have antimicrobial properties that selectively target harmful bacteria in the mouth and allow the good bacteria to thrive. As practitioners, recommending simple dietary changes like these can make a huge difference in a patient’s oral and cardiovascular health.
Using natural antimicrobials in oral care can be beneficial. Ingredients like xylitol, found in sugar-free gums and toothpastes, have been shown to inhibit the growth of harmful bacteria, supporting a balanced oral microbiome. Teach your clients about the impact of their oral hygiene habits on overall inflammation and the critical link between daily care and long-term cardiovascular health.
Uncovering Oral Health Red Flags
Sometimes, the signs of a dysfunctional oral microbiome are not immediately visible, making it vital to dig deeper into a patient’s oral health habits and history. Use targeted questions and observations to assess oral health, which may reveal hidden contributors to chronic inflammation and heart disease.
Gum Health and Inflammation
Swollen, red, or bleeding gums are common indicators of gum disease, such as gingivitis or periodontal disease—both of which can fuel systemic inflammation. Asking, “Have you noticed your gums bleeding during brushing or flossing?” or if they’ve experienced gum recession. Persistent bad breath or a foul taste could also be signs of a deeper issue.
Tooth Sensitivity and Pain
Sensitive teeth, especially in response to hot, cold, or sweet foods, often point to enamel erosion, cavities, or exposed roots due to gum recession. Ask patients if they’ve experienced sensitivity or pain when eating or drinking. This can indicate compromised oral health and increase the risk of inflammation.
Oral Hygiene Practices
Ask about their daily oral care routine. Ask how often they brush and floss, and whether they’ve had recent dental cleanings. Insufficient oral hygiene can allow harmful bacteria to thrive which leads to increased inflammation both locally and systemically.
Dry Mouth (Xerostomia)
A dry mouth can signal decreased saliva production, which creates an environment conducive to bacterial overgrowth. This imbalance can exacerbate both oral and systemic inflammation. Questions about frequent dry mouth, difficulty chewing, or swallowing are key in uncovering potential issues with saliva production.
Dental History and Care Frequency
Ask about their history of cavities, gum disease, or major dental procedures like root canals. These can give a clearer picture into their overall oral and systemic health. Also ask about the frequency of dental visits and any significant dental treatments to get a complete picture of their oral health status.
Imbalance in the Oral Microbiome
Recurrent mouth infections, such as thrush or frequent cold sores, may indicate oral dysbiosis, an imbalance in the microbial population. This imbalance can contribute to wider systemic inflammation. Ask about any recurring mouth infections to determine if there’s an imbalance in the oral microbiome.
Functional Approaches to Managing Inflammation
Getting to the root cause of chronic inflammation is essential in improving cardiovascular and systemic health. For practitioners, this means incorporating comprehensive testing, nutrition strategies, and lifestyle modifications to not only identify inflammation but also reduce it.
Comprehensive Testing for Inflammation: A Deeper Dive
When evaluating a patient's cardiovascular risk, it's important to go beyond the surface and assess the underlying inflammatory processes which can lead to heart disease. Several key blood tests reveal a patient's inflammatory status and help practitioners create personalized interventions.
One of the most widely recognized markers is C-reactive protein (CRP), particularly high-sensitivity CRP (hs-CRP). Elevated levels of CRP are strongly associated with an increased risk of cardiovascular events like heart attacks and strokes. This marker reflects the presence of systemic inflammation. For patients with elevated CRP, reducing inflammation should be a top priority.
Another important marker to assess is homocysteine, an amino acid that, when elevated, can cause oxidative stress and damage to blood vessels and increase the risk of blood clots and promote plaque formation. Elevated homocysteine is often associated with deficiencies in B vitamins (particularly B6, B12, and folate), which are needed to break down this amino acid. Addressing nutritional deficiencies can significantly lower homocysteine levels and reduce cardiovascular risk.
Fibrinogen, a protein involved in blood clot formation, is another critical marker. Elevated fibrinogen levels indicate increased clotting activity, which can lead to dangerous blood clots and thrombotic events. Strategies to lower fibrinogen include lifestyle modifications such as regular physical activity, a plant-based diet rich in fiber and antioxidants, and managing underlying conditions like blood sugar imbalances or high blood pressure.
In addition to these blood tests, functional oral health assessments are crucial. Chronic oral infections, gum disease, and other dental issues can contribute to systemic inflammation and increase cardiovascular risk. There are even oral microbiome testing kits available to assess the types and amounts of bacteria present.
Personalized Nutrition and Inflammation Reduction
Nutritional strategies are important in managing chronic inflammation. Encouraging patients to adopt an anti-inflammatory diet rich in antioxidants, omega-3 fatty acids, and polyphenols can significantly reduce systemic inflammation. Foods like leafy greens, berries, flaxseeds, and walnuts are particularly beneficial. Teach patients to reduce or eliminate processed foods, trans fats, and added sugar, as these are inflammatory.
Find ways to add functional foods like turmeric, ginger, and garlic into your patient's dietary plans. These herbs and spices contain potent anti-inflammatory compounds that support both cardiovascular and oral health. Educating patients on the impact of food choices on inflammation is a critical part of holistic care.
Introduce your clients to recipes like this Gut Healing Salad with Coconut Ginger Dressing that not only contains a variety of colors and foods to balance the microbiome, but also contains anti-inflammatory spices like ginger and turmeric.
Lifestyle Modifications to Control Inflammation
Chronic stress is a significant contributor to inflammation, and stress management techniques such as guided meditation, Heart Math, mindfulness, yoga, and deep breathing can help lower inflammatory markers.
Regular physical activity, tailored to individual needs, is also essential for controlling inflammation. Patients who are sedentary or overly stressed are more likely to experience elevated inflammatory markers which increases their cardiovascular risk.
Ask patients about their sleep. Getting enough sleep is another often overlooked but vital factor. Sleep deprivation disrupts the body’s ability to regulate inflammation. Recommending 7-9 hours of quality sleep, along with sleep hygiene practices, is an essential part of an inflammation-reducing protocol.
Empowering Practitioners to Address the Inflammation-Heart Health Link
