At the Heart of Oral Health

February 7, 2019

You’ve heard us say time and again that oral health is linked to overall health. Most individuals treat their mouths as a separate entity from the rest of their body and ignore the fact that what goes on here has a large correlation to many other health issues. This month we’re focusing on the link to heart disease. Heart disease is the leading cause of death for both men and women in the US. It’s estimated that 1 in every 4 deaths is due to heart disease. Periodontal disease affects nearly 50% of individuals with over 70% prevalence in adults age 65 and older. So how are these 2 very common diseases related?

Let’s start by saying there have been no studies that have PROVEN poor oral health causes heart disease. There are studies however that show a strong correlation between the two, so that’s what we will cover. One of the theories typically written about is that of bacteria. As you may know, our mouths contain a lot of bacteria. We can have anywhere between 100-200 or more different strains of bacteria at any given time. This equates to millions or billions of bacteria living in your oral cavity. Many are helpful or harmless, but some are disease causing. It is these bacteria that have been found in blood vessels causing inflammation, just as they do in our gums.

Our hearts are susceptible to bacteriaNot only do the bacteria cause problems if they end up in your heart and blood vessels, but your bodies natural inflammatory response can also cause damage. When you suffer from gingivitis or periodontal disease, your body reacts with its usual inflammatory response. This doesn’t just occur in your mouth though. The inflammatory response is a nonspecific reaction to pathogens, damaged cells and/or toxins that takes place throughout your entire body (you can learn more about the damage it causes here). It is this reaction to oral pathogens that “sets off a cascade of vascular damage throughout the body, including the heart and brain.” (Harvard).

A 3rd correlation between poor oral health and heart disease is smoking. Smoking is a risk factor for both diseases and may present the link between the two. A 2018 study, analyzed data from a million people who had different cardiovascular events and found that:

  1. Accounting for age, a moderate correlation was found between tooth loss and coronary heart disease (the most common type of heart disease).
  2. After accounting for smoking the correlation largely disappeared.

We could conclude that smoking may very well be the missing piece of the mouth to heart puzzle, but more studies are needed for a definitive answer.

Heart Health is linked to Oral Health
