Research increasingly shows that oral health and overall health are deeply connected. Regular dental checkups don't just protect your teeth—they may help protect your heart, brain, and more.
Did you know that your dental health can significantly impact your overall health?
Researchers have identified associations between oral diseases and nearly 60 systemic health conditions. Over 100 diseases can show symptoms in your mouth, making regular dental checkups important for catching early warning signs of problems throughout your body.
Your family dentist does more than clean your teeth—they can help you maintain good oral health that supports your overall well-being. Having the right dental insurance makes it easier to access the ongoing care you and your family need.
Oral diseases affect nearly 3.5 billion people worldwide, making them among the most common health conditions globally. In the United States, nearly half of adults aged 30 and older show signs of gum disease, and 1 in 5 adults have untreated cavities.
The relationship between oral health and systemic health is increasingly recognized as bidirectional—meaning your oral health affects your overall health, and your overall health affects your oral health. Scientists believe this connection works through several mechanisms, including bacteria entering the bloodstream through inflamed gums and chronic inflammation that spreads throughout the body.
A December 2025 scientific statement from the American Heart Association highlighted growing evidence that gum disease is associated with increased risk of cardiovascular events, including heart attack, stroke, atrial fibrillation, and heart failure. The statement noted that "your mouth and your heart are connected" and that prevention and treatment of gum disease could potentially help reduce the burden of cardiovascular disease.
Healthy Gums, Healthy Body
Periodontal (gum) disease is a chronic inflammatory condition affecting over 40% of U.S. adults over age 30. It begins as gingivitis—inflammation of the gums caused by plaque buildup. If left untreated, gingivitis can progress to periodontitis, where gums pull away from teeth, creating pockets that trap bacteria and lead to infection.
Regular brushing, flossing, and professional cleanings help remove the plaque and bacteria that cause gum disease. Research published in 2025 found that people who brushed three or more times per day had a 7.35% ten-year cardiovascular risk, compared to 13.7% for those who brushed once daily or less.
Reducing Risk of Heart Issues
Bacteria from infected gums can enter your bloodstream and travel throughout your body, including to your heart. This can trigger inflammation that may damage blood vessels and contribute to plaque buildup in arteries (atherosclerosis).
Research consistently shows an association between gum disease and cardiovascular risk. According to Harvard Health, people with gum disease have two to three times the risk of having a heart attack, stroke, or other serious cardiovascular event compared to those with healthy gums. An October 2025 study published in Neurology found that people with both gum disease and cavities had an 86% greater risk of ischemic stroke than those with healthy mouths.
Healthier Lungs
The bacteria in your mouth don't stay there. When you breathe, oral bacteria can travel to your lungs, potentially contributing to respiratory infections like pneumonia—especially in older adults or those with weakened immune systems.
Research has shown that periodontal pathogens can aggravate lung conditions. Maintaining good oral hygiene and treating gum disease may help reduce the bacterial load that could otherwise affect your respiratory health.
Supporting Diabetes Prevention and Management
The relationship between diabetes and gum disease is well-documented and bidirectional. People with diabetes are 2-3 times more likely to develop periodontal disease than those without diabetes, particularly if blood sugar is poorly controlled. At the same time, gum disease appears to make it harder to control blood sugar, potentially worsening diabetes.
The good news: treating gum disease can help. Research shows that successful periodontal treatment is associated with reductions in HbA1c of approximately 0.4%—a meaningful improvement in blood sugar control. The International Diabetes Federation and European Federation of Periodontology recognize oral health as an integral component of diabetes management.
Potential Cancer Connections
Researchers are investigating connections between gum disease and certain cancers. The oral bacterium Porphyromonas gingivalis, which causes periodontitis, has been linked to increased risk of pancreatic cancer in some studies. While the mechanism remains unclear, chronic inflammation and bacterial translocation may play a role.
Smoking compounds these risks significantly. People who smoke and have gum disease face substantially higher risks of oral cancer and other smoking-related cancers.
Brain Health and Cognitive Function
Emerging research suggests a connection between oral health and cognitive decline. A 2025 CDC study found that middle-aged and older adults with poor oral health and those who didn't use regular dental services had a higher prevalence of subjective cognitive decline. While more research is needed to establish causation, chronic inflammation from gum disease may contribute to brain health issues over time.
Pregnancy Health
Poor oral health during pregnancy has been associated with adverse outcomes, including preterm birth and low birth weight. Inflammation and bacterial infection associated with gum disease may affect fetal development. Pregnant women should maintain regular dental care and inform their dentist about their pregnancy to ensure safe, appropriate treatment.
Gum disease often develops without pain, which means many people don't realize they have it. Watch for these warning signs and let your dentist know if you notice any of them:
Gums that bleed when you brush or floss
Red, swollen, or tender gums
Gums that have pulled away from your teeth
Persistent bad breath or a bad taste in your mouth
Loose teeth or teeth that have shifted position
Pain when chewing
Changes in how your teeth fit together when you bite
Brush twice daily for two minutes. Most people don't spend enough time brushing. Use fluoride toothpaste and a soft-bristle brush, and be sure to brush all surfaces of your teeth.
Floss daily. Flossing removes plaque and food particles from between teeth where your toothbrush can't reach. If you find traditional floss difficult to use, try floss picks or a water flosser.
Visit your dentist regularly. Professional cleanings remove tartar (hardened plaque) that you can't remove at home. Most adults should see their dentist at least twice a year, though some people may need more frequent visits.
Tell your dentist about health conditions. Inform your dentist about any conditions such as diabetes, heart disease, or pregnancy. This helps them provide appropriate care and monitor oral health for your overall health.
Don't smoke. Smoking is one of the strongest risk factors for gum disease. CDC data show that about 62% of adults who smoke have periodontitis. Quitting smoking significantly reduces your risk of gum disease and improves treatment outcomes.
Limit sugary and acidic foods. Sugary foods and drinks feed the bacteria that cause cavities and gum disease. Acidic foods can erode tooth enamel. Enjoy these in moderation and rinse your mouth with water afterward.
Stay hydrated. Dry mouth increases the risk of cavities and gum disease. Drink plenty of water throughout the day, especially if you take medications that cause dry mouth.
Only about 64% of U.S. adults visited a dentist in the past year, according to CDC data. Cost is the most common barrier to dental care—even among adults with private dental insurance.
Regular dental visits aren't just about keeping your teeth clean. Research shows that people who visited the dentist regularly were 81% less likely to have both gum disease and cavities, and had 29% lower odds of having gum disease alone. Given the connections between oral health and conditions like heart disease and diabetes, preventive dental care is an investment in your overall health.
Dental insurance can make regular care more affordable by covering preventive services like cleanings and exams, often at no additional cost. It also helps reduce out-of-pocket costs for treatments like fillings, crowns, and periodontal care if problems are detected.

How often should I visit the dentist?
Most adults should see their dentist at least twice a year for professional cleanings and checkups. However, people with gum disease, diabetes, or other health conditions may benefit from more frequent visits. Your dentist can recommend the right schedule for your individual needs.
Can gum disease really affect my heart?
Research consistently shows an association between gum disease and cardiovascular risk. People with gum disease have 2-3 times the risk of heart attack, stroke, or other serious cardiovascular events compared to those with healthy gums. While researchers are still studying whether treating gum disease directly reduces heart disease risk, the connection is compelling enough that the American Heart Association recommends good oral hygiene as part of heart health.
I have diabetes. Should I be concerned about my oral health?
Yes. People with diabetes are 2-3 times more likely to develop gum disease, and gum disease can make it harder to control blood sugar. The good news is that treating gum disease can help improve blood sugar control. Be sure to tell your dentist about your diabetes and maintain regular dental visits as part of your overall diabetes management.
How do I know if I have gum disease?
Gum disease often develops without pain, so you may not know you have it. Watch for warning signs like bleeding gums, red or swollen gums, persistent bad breath, receding gums, or loose teeth. Your dentist can measure pocket depths around your teeth to detect gum disease, which is why regular checkups are important.
Does Medicare cover dental care?
Original Medicare (Parts A and B) generally does not cover routine dental care, such as cleanings, fillings, or dentures. However, many Medicare Advantage plans include dental coverage. Standalone dental plans are also available for Medicare beneficiaries. Our agents can help you understand your Medicare dental coverage options.
What's the difference between gingivitis and periodontitis?
Gingivitis is the earliest stage of gum disease, characterized by inflammation of the gums due to plaque buildup. It's reversible with good oral hygiene and professional cleaning. If left untreated, gingivitis can progress to periodontitis, where the gums pull away from the teeth, forming pockets that trap bacteria. Periodontitis can damage the bone supporting your teeth and may lead to tooth loss.
