Gingivitis, also generally called gum disease or periodontal disease, begins with bacterial growth in your mouth and may end — if not properly treated — with tooth loss due to destruction of the tissue that surrounds your teeth.

What’s the Difference Between Gingivitis and Periodontitis?

Gingivitis (gum inflammation) usually precedes periodontitis (gum disease). However, it is important to know that not all gingivitis progresses to periodontitis.

In the early stage of gingivitis, bacteria in plaque buildup, causing the gums to become inflamed and easily bleed during tooth brushing. Although the gums may be irritated, the teeth are still firmly planted in their sockets. No irreversible bone or other tissue damage has occurred at this stage.

When gingivitis is left untreated, it can advance to periodontitis. In a person with periodontitis, the inner layer of the gum and bone pull away from the teeth and form pockets. These small spaces between teeth and gums collect debris and can become infected. The body’s immune system fights the bacteria as the plaque spreads and grows below the gum line.

What Causes Gum Disease?

Plaque is the primary cause of gum disease. However, other factors can contribute to periodontal disease. These include:

• Hormonal changes, such as those occurring during pregnancy, puberty, menopause, and monthly menstruation, make gums more sensitive, which makes it easier for gingivitis to develop.

• Illnesses may affect the condition of your gums. This

includes diseases such as cancer or HIV that interfere with the immune system. Because diabetes affects the body’s ability to use blood sugar, patients with this disease are at higher risk of developing infections, including periodontal disease and cavities.

• Medications can affect oral health, because some lessen the flow of saliva, which has a protective effect on teeth and gums. Some drugs, such as the anticonvulsant medication Dilantin and the anti-angina drug Procardia and Adalat can cause abnormal growth of gum tissue.

• Bad habits such as smoking make it harder for gum tissue to repair itself.

• Poor oral hygiene habits such as not brushing and flossing on a daily basis make it easier for gingivitis to develop.

• Family history of dental disease can be a contributing factor for the development of gingivitis.

What Are the Symptoms of Gum Disease?

Gum disease may progress painlessly, producing few obvious signs, even in the late stages of the disease. Although the symptoms of periodontal disease often are subtle, the condition is not entirely without warning signs. Certain symptoms may point to some form of the disease. The symptoms of gum disease include:

• Gums that bleed during and after tooth brushing

• Red, swollen, or tender gums

• Persistent bad breath or bad taste in the mouth

• Receding gums

• Formation of deep pockets between teeth and gums

• Loose or shifting teeth

• Changes in the way teeth fit together upon biting down, or in the fit of partial dentures.

Even if you don’t notice any symptoms, you may still have some degree of gum disease. In some people, gum disease may affect only certain teeth, such as the molars. Only a dentist or a periodontist can recognize and determine the progression of gum disease.
