Can treating gum disease improve heart health?


Oral health is not just about having a bright smile; it plays a significant role in our overall well-being. Research in recent years has revealed a potential link between gum disease and heart health, raising questions about whether treating gum disease could have a positive impact on the heart. In this blog post, we will explore the connection between gum disease and heart health, examine the scientific evidence supporting this association, and discuss how treating gum disease may contribute to improving heart health.

Understanding Gum Disease:

Gum disease, also known as periodontal disease, is a bacterial infection that affects the tissues surrounding the teeth. It starts with the accumulation of plaque, a sticky film containing bacteria, on the teeth and gum line. If left untreated, plaque hardens into tartar, leading to inflammation of the gums, known as gingivitis. Gingivitis, if not addressed, can progress to periodontitis, a more severe form of gum disease that involves the loss of bone and connective tissues supporting the teeth.

The Connection Between Gum Disease and Heart Health:

The association between gum disease and heart health is centered on inflammation. Researchers have found that the same bacteria causing gum disease can enter the bloodstream through inflamed gum tissues. Once in the bloodstream, these bacteria may trigger an immune response, leading to systemic inflammation. Chronic inflammation is linked to various cardiovascular problems, including atherosclerosis, heart attacks, and heart failure.

Additionally, inflammatory mediators released during the immune response can contribute to the formation of arterial plaques, which are deposits of cholesterol and other substances on the arterial walls. These plaques can narrow the arteries, restricting blood flow to the heart, and potentially leading to heart-related issues.

Scientific Evidence Supporting the Link:

Numerous studies have investigated the potential link between gum disease and heart health, and while the exact mechanism remains complex and not fully understood, the evidence has been compelling:

A study published in the Journal of the American Heart Association in 2016 found that participants with moderate to severe gum disease had a higher risk of experiencing a major adverse cardiovascular event, such as a heart attack or stroke, compared to those with healthier gums.

A meta-analysis published in the European Journal of Preventive Cardiology in 2019 examined data from 76,037 participants across 21 studies and found a significant association between gum disease and an increased risk of cardiovascular diseases.

Research presented at the American Heart Association’s Scientific Sessions in 2018 suggested that treating gum disease through professional cleaning may lead to a reduction in arterial stiffness, a risk factor for heart disease.

Treating Gum Disease and Its Potential Impact on Heart Health:

Considering the association between gum disease and heart health, it becomes crucial to explore whether treating gum disease could potentially improve heart health:

Reducing Systemic 

Inflammation: By effectively treating gum disease and preventing the spread of harmful bacteria from the mouth into the bloodstream, we may be able to reduce systemic inflammation, thus potentially lowering the risk of cardiovascular issues.

Improving Endothelial Function: 

Endothelial cells line the interior surface of blood vessels and play a crucial role in regulating blood flow. Chronic inflammation can impair endothelial function, contributing to the development of cardiovascular diseases. Treating gum disease may help improve endothelial function, promoting better heart health.

Managing Risk Factors: 

Treating gum disease can also lead to improved oral hygiene practices, which may indirectly influence other cardiovascular risk factors. For example, a commitment to good oral health could encourage individuals to quit smoking, adopt a healthier diet, and manage chronic conditions like diabetes more effectively, all of which positively impact heart health.

The Importance of Comprehensive Dental Care:

To reap potential benefits for heart health, it’s essential to prioritize comprehensive dental care, including regular check-ups and cleanings. Dentists can detect gum disease at its earliest stages and provide appropriate treatment. Dental professionals may recommend scaling and root planing, a deep cleaning procedure to remove plaque and tartar from below the gumline. In more severe cases, surgical intervention might be necessary to restore gum health and prevent further damage.


While the link between gum disease and heart health is still an area of ongoing research, the evidence suggests a strong association between the two. Treating gum disease and maintaining good oral hygiene may play a role in reducing systemic inflammation and promoting heart health. However, it’s important to remember that oral health is just one aspect of overall well-being. Adopting a heart-healthy lifestyle, including regular exercise, a balanced diet, and routine medical check-ups, is equally crucial for preserving cardiovascular health. As research continues to unfold, emphasizing the importance of comprehensive dental care and its potential impact on heart health is a step towards promoting better overall health and well-being.
