Can gingivitis be fatal?

When assessing your risk for heart disease, your healthcare provider might evaluate factors like cholesterol levels, blood pressure, physical activity, weight, and diet. What if they also asked how frequently you brush and floss? While such questions are typical at dental appointments, they might soon become common during routine medical checkups. Research is increasingly showing a strong connection between oral health and overall well-being.

Maintaining a routine of brushing and flossing at least twice daily is scientifically proven to promote oral health. Periodontal disease involves inflammation and infection of the gums, tissues, and ligaments that secure teeth in place. It ranges from mild gingivitis to severe chronic periodontitis, which can lead to tooth loss.

Plaque is the primary culprit behind gum disease. When plaque, a sticky layer composed of sugars, bacteria, and mucus, accumulates on teeth, it can lead to cavities, harden into tartar, and create an environment conducive to gingivitis. Beyond plaque, factors like smoking, tobacco use, certain illnesses such as diabetes, cancer, and HIV, medications causing dry mouth, hormonal changes in women (e.g., puberty and menopause), and genetics also play a role in increasing the risk of gum disease.

Many individuals don't notice gum disease symptoms until their 30s or 40s. Signs of gingivitis include tender, swollen, or bleeding gums, tooth sensitivity, and surprisingly, chronic bad breath. As the condition worsens, symptoms like receding gums, loose teeth, tooth loss, and pain while chewing may develop. The inflammation and infection can affect the entire mouth or only specific teeth.

Are swollen gums truly a significant concern?

Absolutely, and not just because they can progress to severe gum disease and tooth loss. Certain oral health issues, such as cavities, gingivitis, and missing teeth, are as strong as cholesterol levels in predicting the risk of coronary artery disease [source: Griffin]. Surprisingly, flossing could potentially help prevent heart attacks.

The Periodontitis and Atherosclerosis Link

The leading theory connecting periodontal disease and coronary heart disease can be summarized in one word: inflammation.

Inflammation occurs when the immune system responds to foreign invaders like viruses or bacteria. While this response is essential for maintaining health, an overactive immune system can lead to chronic issues such as allergies, asthma, rheumatoid arthritis, and other autoimmune disorders. Inflammation is also believed to contribute to chronic conditions like depression, cancer, diabetes, and heart disease.

Inflammation is associated with atherosclerosis, a condition where arteries harden, though it's unclear whether the inflammation is systemic or localized. In periodontal disease, plaque buildup releases bacterial toxins that infect and inflame the gums, potentially leading to chronic, systemic inflammation if untreated. Studies reveal that the bacteria found in gum disease are also present in the fatty plaques that thicken blood vessel walls and harden arteries, indicating a connection between the two conditions. The American Academy of Periodontology notes that individuals with gum disease are nearly twice as likely to suffer from heart disease compared to those with healthy gums [source: Griffin].

To prevent gum disease, maintain proper brushing and flossing habits and visit your dentist twice a year. While it's uncertain whether gum disease bacteria cause atherosclerosis or vice versa, you can request a test to measure inflammation levels in your body. Elevated levels of C-reactive protein (CRP), a marker of inflammation, may indicate the need for further medical evaluation.
