What Is Periodontal Disease?

If your hands bled when you washed them, you would be concerned. Yet, many people think it’s normal if their gums bleed when they brush or floss. In a 1999 study, researchers at the U.S. National Institutes of Health (NIH) found that half of Americans over 30 had bleeding gums.

Swollen and bleeding gums are early signs that your gums are infected with bacteria. If nothing is done, the infection can spread and destroy the structures that support your teeth in your jawbone. Eventually, your teeth can become so loose that they have to be extracted.

“Perio” means around, and “dontal” refers to teeth. Periodontal diseases are infections of the structures around the teeth, which include the gums, periodontal ligament and alveolar bone. In the earliest stage of periodontal disease — gingivitis — the infection affects the gums. In more severe forms of the disease, all of the tissues are involved.

For many years scientists have been trying to figure out what causes periodontal disease. It is now well accepted that various types of bacteria in dental plaque are the major villains. Researchers also are learning more about how an infection in your gums can affect your overall health.

In recent years, gum disease has been linked to a number of other health problems. This is a new and exciting area of research, but it remains controversial. Studies have produced varying answers about the extent of the connection between gum disease and other medical problems, and more research is needed.

Researchers are studying possible connections between gum disease and:

  • Atherosclerosis and heart disease — Gum disease may increase the risk of clogged arteries and heart disease, although the extent of this connection is unclear. Gum disease also is believed to worsen existing heart disease.
  • Stroke — Gum disease may increase the risk of the type of stroke that is caused by blocked arteries.
  • Diabetes — People with diabetes and periodontal disease may be more likely to have trouble controlling their blood sugar than diabetics with healthy gums.
  • Respiratory disease— Gum disease may cause lung infections and worsen existing lung conditions when bacteria from the mouth reach the lungs.
