The Mouth-Heart Connection: How Oral Health Impacts Cardiovascular Wellness

The Mouth-Heart Connection: How Oral Health Impacts Cardiovascular Wellness

When we think about heart health, we often focus on factors like diet, exercise, and cholesterol levels. However, emerging research suggests that oral health may also play a significant role in cardiovascular wellness. Brushing less than twice a day may increase inflammatory markers such as C-reactive protein (CRP) (Vaishnava et al., 2011)

Studies have shown a strong link between gum disease (periodontitis) and heart disease. The bacteria that cause gum disease can enter the bloodstream through the gums, potentially leading to inflammation and narrowing of the arteries (atherosclerosis). This, in turn, can increase the risk of heart attack and stroke (Vaishnava et al., 2011).

Furthermore, individuals with gum disease may also be more prone to other risk factors for heart disease, such as diabetes and high blood pressure. Poor oral health habits, such as infrequent brushing and flossing, can exacerbate these risks.

A recent Korean study identified three indications of poor dental health: periodontal disease, tooth loss, and dental caries. Participants in the study who brushed their teeth at least once a day saw a 9% decrease in cardiovascular risk. Yearly visits to the dentist decreased that risk by 14% (Park et al., 2019).

Maintaining good oral hygiene is crucial for both oral and cardiovascular health. Brushing twice daily, flossing daily, and visiting the dentist regularly can help prevent gum disease and reduce the risk of associated heart problems. A healthy diet low in sugar and regular exercise can further support overall heart health.

According to the non-profit Care Quest Institute for Oral Health, 29% of Americans lack dental insurance. The number of rural Americans without dental insurance is even higher.  If you cannot afford regular visits to the dentist, that makes it even more important to brush and floss regularly and to avoid sugary foods.
