What causes gum disease?

Our mouths are full of bacteria. These bacteria, along with mucus and other particles, constantly form a sticky, colorless "plaque" on teeth. Brushing and flossing help get rid of plaque. Plaque that is not removed can harden and form "tartar" that brushing doesn't clean. Only a professional cleaning by a dentist or dental hygienist can remove tartar.

Gingivitis

The longer plaque and tartar are on teeth, the more harmful they become. The bacteria cause inflammation of the gums that is called "gingivitis." In gingivitis, the gums become red, swollen and can bleed easily. Gingivitis is a mild form of gum disease that can usually be reversed with daily brushing and flossing, and regular cleaning by a dentist or dental hygienist. This form of gum disease does not include any loss of bone and tissue that hold teeth in place.

Periodontitis

When gingivitis is not treated, it can advance to "periodontitis" (which means "inflammation around the tooth"). In periodontitis, gums pull away from the teeth and form spaces (called "pockets") that become infected. The body's immune system fights the bacteria as the plaque spreads and grows below the gum line. Bacterial toxins and the body's natural response to infection start to break down the bone and connective tissue that hold teeth in place. If not treated, the bones, gums, and tissue that support the teeth are destroyed. The teeth may eventually become loose and have to be removed.

Who gets gum disease?

People usually don't show signs of gum disease until they are in their 30s or 40s. Men are more likely to have gum disease than women. Although teenagers rarely develop periodontitis, they can develop gingivitis, the milder form of gum disease. Most commonly, gum disease develops when plaque is allowed to build up along and under the gum line.

How is gum disease treated?

The main goal of treatment is to control the infection. The number and types of treatment will vary, depending on the extent of the gum disease. Any type of treatment requires that the patient keep up good daily care at home. The doctor may also suggest changing certain behaviors, such as quitting smoking, as a way to improve treatment outcome.

Can gum disease cause health problems beyond the mouth?

In some studies, researchers have observed that people with gum disease (when compared to people without gum disease) were more likely to develop heart disease or have difficulty controlling blood sugar. Other studies showed that women with gum disease were more likely than those with healthy gums to deliver preterm, low birth weight babies. But so far, it has not been determined whether gum disease is the cause of these conditions.More research is needed to clarify whether gum disease actually causes health problems beyond the mouth, and whether treating gum disease can keep other health conditions from developing.
