Your Smile and Your Heart: The Surprising Connection Between Oral Health and Cardiovascular Disease

February brings Valentine’s Day hearts, but it’s also American Heart Month—a reminder to pay attention to cardiovascular health. At Wauwatosa Family Dental, we talk with patients every day about the importance of healthy gums, and one reason may surprise you: research continues to reveal links between gum disease and serious cardiovascular conditions.

If you’ve been putting off dental visits or dismissing bleeding gums as no big deal, this connection gives you another compelling reason to prioritize your oral health. Understanding how bacteria in your mouth can affect your entire body might just change how you think about brushing, flossing, and those twice-yearly cleanings.

The Mouth-Body Connection

Your mouth is home to hundreds of species of bacteria. Most are harmless, and good oral hygiene keeps them under control. However, when plaque builds up along the gumline and between teeth, harmful bacteria multiply and can cause infection in the gum tissue. This infection—known as periodontal disease or gum disease—doesn’t stay contained to your mouth.

When gums become inflamed and infected, bacteria can enter your bloodstream through the tiny blood vessels in your gum tissue. Every time you chew, brush, or even just move your mouth, these bacteria have an opportunity to travel throughout your body. Once in the bloodstream, they can contribute to inflammation elsewhere, including in the arteries that supply blood to your heart.

What Research Tells Us

Studies have found that people with moderate to severe gum disease face a higher risk of heart disease compared to those with healthy gums. The American Heart Association has acknowledged the association between periodontal disease and cardiovascular disease, though researchers are still working to understand the exact mechanisms involved.

Several theories explain the connection:

• Systemic Inflammation: Chronic gum infection triggers an inflammatory response that doesn’t stay localized. This ongoing inflammation may contribute to the buildup of fatty deposits in arteries, a condition called atherosclerosis.
• Bacterial Spread: Specific bacteria found in infected gums have been discovered in arterial plaques. Their presence suggests these oral bacteria may directly contribute to cardiovascular problems.
• Shared Risk Factors: Conditions like diabetes, smoking, and poor nutrition increase risk for both gum disease and heart disease. Managing these factors benefits both your mouth and your cardiovascular system.

Warning Signs You Shouldn’t Ignore

Gum disease often develops gradually, and early stages may not cause pain. Many people live with periodontal disease without realizing it. The team at Wauwatosa Family Dental screens for gum disease at every checkup, but knowing the warning signs helps you catch problems between visits:

• Bleeding Gums: Gums that bleed when you brush or floss aren’t normal. While many people assume some bleeding is expected, healthy gums shouldn’t bleed from regular cleaning.
• Red or Swollen Gums: Healthy gum tissue appears pink and firm. Redness, puffiness, or tenderness indicates inflammation that needs attention.
• Persistent Bad Breath: Occasional bad breath happens to everyone, but chronic bad breath that doesn’t improve with brushing may signal bacterial buildup beneath the gumline.
• Receding Gums: If your teeth appear longer than they used to, or you notice your gumline pulling away from your teeth, gum disease may be the cause.
• Loose Teeth: Advanced gum disease destroys the bone and tissue supporting your teeth, eventually causing them to loosen or shift.
• Changes in Your Bite: If your teeth fit together differently than before, or if partial dentures no longer fit properly, underlying bone loss may be occurring.

Prevention Starts at Home

Protecting your gums—and by extension, potentially your heart—begins with daily habits that control bacterial growth in your mouth:

• Brush twice daily using fluoride toothpaste and a soft-bristled brush. Angle the bristles toward your gumline to clean where bacteria accumulate. Replace your toothbrush every three to four months, or sooner if bristles become frayed.
• Floss every day to remove plaque and food particles from between teeth where your toothbrush can’t reach. If traditional floss feels awkward, water flossers and interdental brushes offer effective alternatives.
• Consider an antibacterial mouthwash as part of your routine. While mouthwash doesn’t replace brushing and flossing, it can help reduce bacterial levels throughout your mouth.
• Watch your diet. Sugary foods and drinks feed the bacteria that cause gum disease. A diet rich in fruits, vegetables, and whole grains supports both oral health and cardiovascular health.
• Don’t smoke. Tobacco use dramatically increases your risk for gum disease and makes existing gum problems harder to treat. It’s also a major risk factor for heart disease.

Professional Care Makes a Difference

Even with excellent home care, you need professional cleanings to remove tartar—hardened plaque that can’t be removed by brushing alone. During visits to Wauwatosa Family Dental, our hygienists thoroughly clean above and below the gumline while our doctors examine your gum tissue, measure pocket depths around each tooth, and identify early signs of disease before they progress.

If gum disease is present, we offer gum disease treatment options ranging from deep cleaning procedures that remove bacteria from below the gumline to more advanced therapies for severe cases. Catching gum disease early makes treatment simpler and more effective.

For patients who’ve avoided dental visits due to anxiety, we offer sedation dentistry options to make appointments more comfortable. Putting off care only allows problems to worsen, so finding a way to get treatment matters for your long-term health.

A Whole-Body Approach to Health

The connection between oral health and heart health reminds us that our bodies function as integrated systems. What happens in one area affects others. Taking care of your teeth and gums isn’t just about maintaining a nice smile—it’s part of taking care of your whole self.

This American Heart Month, consider scheduling a dental checkup if it’s been a while. Ask about the health of your gums and what you can do to reduce inflammation in your mouth. These simple steps may benefit more than just your smile.
