How the Dentist Helps Your Heart


Story Updated: Dec 6, 2012

No matter how busy you are, here is another reason you should make time for regular dental visits: They can save your life.

Heart disease is the biggest killer of American women, and women who get adequate dental care reduce their risk of heart attack, stroke and other cardiovascular problems by at least one-third, according to a new study from the University of California, Berkeley. The study links artery-clogging plaque, a major cause of heart attack and stroke, to bacteria in the mouth.

The Berkeley study, which involved people over age 43, also found that while women receiving dental care reduced their cardiovascular risk by at least one-third, men did not see any heart health benefit. This may be because dental care has the most effect in the earliest stages of heart disease, says lead author Timothy Brown, Ph.D., a professor of health policy and management at UC Berkeley's School of Public Health. Since women tend to develop heart disease about 10 years later than men, the women in the study were less likely to have advanced heart disease.

How can you tell if plaque is taking you down the wrong path? "If your gums bleed when you floss or brush, it's quite possible that bacteria are getting into the bloodstream that could lead to stroke or heart attack later in life," says Kevin Muench, a family dentist in Maplewood, N.J. So get to the dentist soon -- regular dental visits typically involve preventive procedures to keep gums healthy and guard against inflammation, which can create a portal into the bloodstream for bacteria.

And if you're not due back to the dentist in a while, follow the two cardinal rules of long-term health in the meantime to reduce your risk of heart disease and keep your smile healthy:

1. Slow down on sugar.

Sugar, long associated with cavities, is now being blamed for increasing risk of heart disease. Last year, the American Heart Association recommended limiting daily sugar intake to about 6 teaspoons for women and about 9 teaspoons for men.

2. Make flossing a habit.

Regular flossing may reduce risk of heart attack, according to a new study from University of Bristol in England. Flossing daily helps reach those areas of the mouth the toothbrush can't, protecting against inflamed gums, which open the door to dangerous bacteria that may trigger deadly heart disease.

Guthrie Cardiovascular Center

Consistently ranked among the top 100 cardiovascular hospitals by Thomson Reuters, Guthrie cardiologists, cardiac surgeons, and vascular surgeons work together to ensure patients receive the most comprehensive care possible.

Offering cardiovascular care to the Twin Tiers for more than 40 years, Guthrie’s cardiac specialists and staff have offered the people of our region the most advanced diagnostic and therapeutic services possible, while earning national awards for quality and recognition for excellence.

Diagnostic & Non-Invasive Cardiology
Non-invasive cardiology includes all procedures that allow the cardiologist to obtain information about the heart without going through the skin or invading the body in any way. Many times these procedures are the first steps in evaluating a patient's condition. Guthrie provides diagnostic and non-invasive cardiology services, including multi-slice CT angiography, comprehensive mobile echocardiography services including stress echo, EKG, holter monitoring and nuclear stress testing to name a few.

Invasive & Interventional Cardiology
When non-invasive techniques don't provide all the answers, additional diagnostic procedures may be used to more clearly identify and treat cardiac problems. Within Guthrie’s Cardiac Catheterization Laboratories, invasive and interventional cardiologists offer subspecialty diagnostic and therapeutic services to evaluate and treat cardiac conditions without traditional surgery. Guthrie interventional cardiologists perform over 100 peripheral vascular interventions, such as carotid angioplasty and stenting, each year, with a 95% technical success rate.

Electrophysiology & Pacing
The heart's conduction system, the system that controls the rate and rhythm of the heartbeat, can develop problems that interfere with the heart's ability to function properly. Electrophysiology Laboratory team offers complete electrophysiology and pacing services for treatment of arrhythmias – from palpitations and syncope to atrial fibrillation to more specialized rhythm abnormalities.

Cardiac Surgery
Surgery plays an important role in a comprehensive cardiac program. Whatever the patient's needs, they can be met by the Guthrie’s cardiac surgery team. Guthrie’s Cardiac Surgery team provides a comprehensive scope of surgical procedures for the treatment of diseases of the heart and chest. Commonly treated conditions include ischemic heart disease, ventricular aneurysms, valve dysfunction, rheumatic heart disease, cardiac arrhythmia, trauma, cardiac tumors and infection.

Thoracic Surgery
Providing the advanced surgical techniques and oncologic therapies, thoracic surgery at Guthrie is dedicated to the prevention, early diagnosis and treatment of non-cardiac diseases of the chest. We are able to apply the modern techniques of minimally invasive procedures including video-assisted thoracic surgery (VATS) to many disease processes for the diagnosis and treatment of lung cancer and other chest diseases.

Vascular & Endovascular Surgery
Guthrie’s Department of Vascular and Endovascular Surgery offers a full spectrum of services – from life-saving procedures to repair ruptured aneurysms to elective procedures to prevent stroke, provide relief from claudication and address symptoms of venous disease. The latest therapies and minimally invasive endovascular treatment are offered by our experienced vascular team.
