The link between gum infection and heart trouble


When it comes to our overall health, we often focus on different aspects of our body in isolation. However, recent research has revealed a significant connection between oral health and cardiovascular well-being. Gum infection, also known as periodontal disease, has emerged as a potential indicator of heart trouble. This finding underscores the importance of maintaining good oral hygiene and seeking regular dental care to safeguard not just our smiles but our hearts as well.


The Oral-Systemic Connection

Medical and dental professionals have long recognized the relationship between oral health and overall health. The oral-systemic connection emphasizes the impact that oral conditions can have on other parts of the body, including the heart. Gum infection, in particular, has gained attention as a potential indicator of cardiovascular problems.


The Link to Heart Disease

Several studies have pointed to a strong association between gum infection and heart disease. A recent study published in JACC: Clinical Electrophysiology conducted by researchers at Hiroshima University shed light on this connection. The study examined 76 patients with cardiac disease and found a significant correlation between periodontitis (gum infection) and fibrosis, which can lead to an irregular heartbeat called atrial fibrillation. The researchers hypothesized that the chronic inflammation associated with periodontitis exacerbates atrial fibrosis and contributes to the development of heart problems.


Understanding the Mechanisms

To understand the link between gum infection and heart trouble, it's crucial to examine the underlying mechanisms. Chronic inflammation, a characteristic of periodontal disease, is considered a key contributor to cardiovascular problems. Inflammation in the gums triggers a systemic inflammatory response throughout the body, which can impact blood vessels and increase the risk of atherosclerosis (plaque buildup in the arteries).


Furthermore, the study conducted by Hiroshima University researchers found that the severity of periodontitis correlated with the severity of fibrosis in the left atrial appendages of the heart. Professor Yukiko Nakano, corresponding author of the study, explains, "This study provides basic evidence that periodontitis can aggravate atrial fibrosis and can be a novel modifiable risk factor for atrial fibrillation." The presence of specific bacteria associated with gum infection in arterial plaques further supports the notion that oral health can directly affect heart health.


Recognizing the Warning Signs

Given the potential correlation between gum infection and heart trouble, it's essential to be aware of the warning signs and symptoms. These may include persistent bad breath, red or swollen gums, bleeding gums, receding gums, tooth sensitivity, loose teeth, changes in bite alignment, and pain or discomfort while chewing. If any of these symptoms are experienced, consulting both a dentist and a healthcare professional is advisable to comprehensively evaluate oral and cardiovascular health.


Prevention and Maintenance

Prevention is key when it comes to oral health and heart disease. To reduce the risk of gum infection and its potential impact on cardiovascular health, adopting the following practices is crucial:

  • Maintain a consistent oral hygiene routine: Brush your teeth twice a day, floss regularly, and use an antibacterial mouthwash to keep your gums healthy and reduce the risk of infection.

  • Book regular dental check-ups: Visit By The Lake Dental every 4-6 months for your hygiene appointments. It enables early detection and treatment of gum disease, preventing its progression.

  • Adopt a heart-healthy lifestyle: Embrace a balanced diet, engage in regular exercise, manage stress effectively, and avoid tobacco products. These lifestyle choices contribute to both oral and cardiovascular health.


The revelation that gum infection could be a major sign of heart trouble highlights the interconnected nature of our body's systems. Taking care of our oral health goes beyond maintaining a beautiful smile—it also protects our overall well-being, including our hearts.
