Most people think of brushing and flossing as ways to prevent cavities and keep their smile healthy. But good oral hygiene may also play a role in protecting your overall health, including your heart.
Researchers have found a consistent link between gum disease and cardiovascular disease. While scientists are still studying exactly how the two conditions are connected, maintaining healthy gums is considered an important part of overall health.
Poor oral health, particularly gum disease, has been linked to a higher risk of heart disease. Although researchers have not proven that gum disease directly causes heart disease, reducing inflammation and maintaining good oral hygiene may support both oral and cardiovascular health.
Is there really a connection between oral health and heart disease?
Yes.
Numerous studies have found that people with periodontal (gum) disease are more likely to develop cardiovascular disease than those with healthy gums.
The American Heart Association states that periodontal disease and cardiovascular disease share several common risk factors, including smoking, diabetes, and increasing age. While the association is well established, current evidence has not proven that gum disease directly causes heart disease.
Even so, experts agree that maintaining good oral health is an important part of supporting your overall health.
What is gum disease?
Gum disease, also called periodontal disease, is an infection of the tissues that support your teeth.
It begins when plaque, a sticky film of bacteria, builds up around the gumline.
Without regular brushing, flossing, and professional cleanings, plaque can harden into tartar, which cannot be removed with brushing alone.
Over time, inflammation may damage the gums and supporting bone.
According to the Centers for Disease Control and Prevention (CDC), nearly half of adults aged 30 years and older have some form of periodontal disease.
How could gum disease affect the heart?
Researchers believe inflammation may play an important role.
When gum tissue becomes chronically inflamed, bacteria and inflammatory molecules may enter the bloodstream.
Scientists are investigating whether this ongoing inflammation contributes to changes in blood vessels that increase cardiovascular risk.
Although more research is needed to fully understand the relationship, inflammation is recognized as an important factor in both periodontal disease and cardiovascular disease.
What are the signs of gum disease?
Early gum disease can be easy to overlook.
Common symptoms include:
- Bleeding gums while brushing or flossing
- Red or swollen gums
- Persistent bad breath
- Tender gums
- Receding gums
- Loose teeth in more advanced disease
Because early treatment is often simpler and more effective, it’s important to schedule a dental appointment if you notice these symptoms.
What increases your risk for gum disease?
Several factors can increase your chances of developing periodontal disease.
These include:
- Smoking or tobacco use
- Diabetes
- Poor oral hygiene
- Dry mouth
- Certain medications
- Hormonal changes
- Family history
- Increasing age
Many of these same factors also increase cardiovascular risk, which is one reason researchers continue studying the relationship between oral health and heart disease.
Can treating gum disease reduce heart disease risk?
Researchers are still working to answer this question.
Treating gum disease clearly improves oral health by reducing infection and inflammation in the mouth.
Whether treatment directly lowers the risk of heart attack or stroke remains an area of active research.
The American Dental Association recommends maintaining healthy gums regardless, because preventing periodontal disease offers significant benefits for oral health and overall well-being.
How can you improve your oral health?
Healthy daily habits can reduce your risk of gum disease.
The American Dental Association recommends:
- Brushing twice daily with fluoride toothpaste
- Cleaning between your teeth every day with floss or another interdental cleaner
- Seeing your dentist regularly
- Eating a balanced diet
- Limiting sugary foods and drinks
- Avoiding tobacco products
If you smoke, quitting benefits both your mouth and your cardiovascular health.
What about other health conditions?
Researchers continue studying connections between oral health and other conditions, including:
- Diabetes
- Pregnancy complications
- Respiratory infections
- Rheumatoid arthritis
Some of these relationships are stronger than others, and scientists are still learning how oral inflammation interacts with the rest of the body.
Regardless, maintaining good oral hygiene remains an important part of preventive healthcare.
When should you see a dentist?
Schedule a dental appointment if you notice:
- Bleeding gums
- Persistent bad breath
- Gum swelling
- Loose teeth
- Pain while chewing
- Gum recession
Routine dental visits also help identify problems before they become more serious.
Most people benefit from regular dental checkups, although your dentist may recommend more frequent visits if you have a history of gum disease.

Frequently asked questions
Can poor oral health cause heart disease?
Researchers have found a strong association between gum disease and heart disease, but current evidence has not established a direct cause-and-effect relationship.
Why is gum disease linked to heart disease?
Inflammation appears to be an important factor. Scientists believe bacteria and inflammatory responses associated with gum disease may contribute to cardiovascular health, although research is ongoing.
Does brushing your teeth help your heart?
Brushing and flossing help prevent gum disease, which has been linked to cardiovascular disease. Good oral hygiene supports overall health even though it has not been proven to directly prevent heart disease.
What are the early signs of gum disease?
Common signs include bleeding gums, swollen gums, persistent bad breath, gum tenderness, and receding gums.
How often should I see a dentist?
Most adults benefit from regular dental checkups. Your dentist may recommend more frequent visits if you have gum disease or other oral health concerns.
