American Heart Month – Show Some Heart

Medically Reviewed by Dr. Kris A. Johnson, DDS on July 29, 2026

Heart disease is the leading cause of death for both men and women in the United States, and most of the damage builds quietly for years before anyone notices a symptom. That is why cardiologists have long called it the silent killer. What surprises many of our patients is that a second, closely related condition builds just as quietly inside the mouth, and the two are more connected than most people realize.

Every February, American Heart Month gives us a reason to talk openly about heart health, and at Harbour Pointe Family Dentistry, we like to use the occasion to talk about the mouth-heart connection specifically. Our Mukilteo dental team sees the early warning signs of gum disease every day, and we want you to understand why keeping up with your dental visits is about more than a bright smile.

Why Heart Disease Is Called the Silent Killer

Heart disease often develops without any pain, pressure, or obvious warning until a major event like a heart attack or stroke occurs. Plaque can build up inside artery walls for decades, narrowing blood flow gradually enough that the body adapts without raising an alarm. By the time symptoms appear, the underlying disease is often already advanced. This is part of why researchers and public health organizations have spent so much energy trying to identify earlier warning signs, including ones that show up in unexpected places, like your gums.

Periodontal Disease Is Called the Silent Disease for the Same Reason

Gum disease, known clinically as periodontal disease, shares that same quiet progression. Early gum disease, called gingivitis, can cause mild redness or bleeding that many people dismiss as normal. Left untreated, it can advance into periodontitis, where the infection moves below the gumline and begins to affect the bone that holds your teeth in place. Because periodontitis rarely causes significant pain in its early stages, people often do not seek treatment until the disease is well established.

What Current Research Says About Gum Disease and Your Heart

The American Heart Association released an updated scientific statement on periodontal disease and atherosclerotic cardiovascular disease, building on years of newer research into how the two conditions interact. According to that statement, gum disease has been associated with a higher risk of major cardiovascular events, including heart attack and stroke, and researchers have found evidence that the bacteria responsible for gum disease can enter the bloodstream through inflamed gum tissue. Once in the bloodstream, these bacteria may contribute to inflammation in blood vessels, a process closely tied to the plaque buildup seen in atherosclerosis. Research summarized by the American Heart Association points out that treating gum disease has also been shown to improve markers associated with heart disease risk, including certain blood pressure and cholesterol measures, which suggests the relationship runs in both directions.

None of this means gum disease causes heart disease outright, and researchers are still working to fully understand the mechanisms involved. What the data does show is a strong enough association that dental and medical organizations now encourage patients to treat the two conditions as connected rather than separate.

Warning Signs of Gum Disease You Should Not Ignore

Because periodontal disease progresses quietly, knowing the early warning signs matters. Gums that bleed when you brush or floss, gums that look red or swollen, persistent bad breath, teeth that feel loose, or gums that appear to be pulling away from your teeth can all point to gum disease. If you have noticed any of these signs, our guide on the signs of gum disease walks through what to watch for in more detail, and our page on what causes receding gums covers another common early symptom.

Everyday Habits That Support Both Your Smile and Your Heart

The good news is that the habits that protect your gums are the same habits that support your overall cardiovascular health. Brushing twice daily, flossing once a day, and eating a diet lower in added sugar all reduce the bacterial load that can trigger gum inflammation. Routine professional cleanings remove the hardened plaque, known as tartar, that a toothbrush cannot reach on its own, and regular dental exams allow us to catch early gum changes before they progress. Good hygiene habits at home between visits make a measurable difference as well.

Quitting smoking is another habit that benefits both conditions at once, since smoking is a major risk factor for both periodontal disease and cardiovascular disease. If you manage a chronic condition like diabetes, keeping it well controlled also reduces your risk for gum disease, since elevated blood sugar can make gum tissue more vulnerable to infection.

Progress We Are Making Against Heart Disease

Heart health awareness campaigns have driven real, measurable change over the past several decades. Consider some of the shifts public health researchers have tracked:

• Death rates from heart disease among women have declined substantially since national awareness campaigns began prioritizing women’s cardiovascular health.
• Public awareness that heart disease is the leading cause of death has grown significantly compared with a generation ago.
• Smoking rates, one of the biggest shared risk factors for heart disease and gum disease, have continued a long-term decline nationally.
• More people are scheduling regular checkups, including dental visits, as part of a broader approach to preventive health.

These trends show that consistent awareness and small daily habits genuinely move the needle over time, both for your heart and for your smile.

How Routine Dental Visits Support Your Overall Health

We think of every dental exam as a chance to check in on more than just your teeth. When we look for early gum disease, we are also watching for one of the possible contributors to broader inflammation in the body. Keeping a consistent schedule of family dentistry visits gives us the chance to catch small changes early, rather than waiting until a problem has already progressed. Many patients are surprised by how much a comprehensive approach to dental care can pick up, and our page on comprehensive family dentistry in Mukilteo explains what a well-rounded dental visit typically includes.

We understand that heart health can feel like a heavy topic, and it is normal to put off thinking about it until something forces the issue. Our goal is to make it easier to stay ahead of small problems, both in your mouth and in your overall health, through visits that feel comfortable rather than stressful.

Dr. Kris A. Johnson and our team take a whole-patient approach to every visit, looking beyond the surface of your smile to flag changes that might matter for your broader health. If it has been a while since your last cleaning and exam, American Heart Month is a fitting reminder to get back on schedule. You can reach our team through our contact page to find a visit time that works for your schedule.
