Overview

Periodontitis (per-e-o-don-TIE-tis) is a serious gum infection that damages the soft tissue and destroys the bone that supports your teeth. Periodontitis can cause teeth to loosen or lead to tooth loss.

Periodontitis is common but largely preventable. It's usually the result of poor oral hygiene. Brushing at least twice a day, flossing daily and getting regular dental checkups can greatly improve your chances of successful treatment for periodontitis and can also reduce your chance of developing it.

Symptoms

Healthy gums are firm and pale pink and fit snuggly around teeth. Signs and symptoms of periodontitis can include:

• Swollen or puffy gums
• Bright red, dusky red or purplish gums
• Gums that feel tender when touched
• Gums that bleed easily
• Gums that pull away from your teeth (recede), making your teeth look longer than normal
• New spaces developing between your teeth
• Pus between your teeth and gums
• Bad breath
• Loose teeth
• Painful chewing
• A change in the way your teeth fit together when you bite

There are several different types of periodontitis. The more common types include those below.

• Chronic periodontitis is the most common type, affecting mostly adults, though children can be affected, too. This type is caused by plaque buildup and involves slow deterioration that may improve and get worse over time but causes destruction in the gums and bone and loss of teeth if not treated.
• Aggressive periodontitis usually begins in childhood or early adulthood and affects only a small number of people. It tends to affect families and causes rapid progression of bone and tooth loss if untreated.
• Necrotizing periodontal disease is characterized by the death of gum tissue, tooth ligaments and supporting bone caused by lack of blood supply (necrosis), resulting in severe infection. This type generally occurs in people with a suppressed immune system — such as from HIV infection, cancer treatment or other causes — and malnutrition.

When to see a dentist

Follow your dentist's recommended schedule for regular checkups. If you notice any symptoms of periodontitis, make an appointment with your dentist as soon as possible. The sooner you seek care, the better your chances of reversing damage from periodontitis.

Causes

In most cases, periodontitis begins with plaque — a sticky film composed mainly of bacteria. If left untreated, here's how plaque can eventually advance to periodontitis:

• Plaque forms on your teeth when starches and sugars in food interact with bacteria normally found in your mouth. Brushing your teeth twice a day and flossing once a day removes plaque, but plaque re-forms quickly.
• Plaque can harden under your gumline into tartar (calculus) if it stays on your teeth. Tartar is more difficult to remove and it's filled with bacteria. The longer plaque and tartar remain on your teeth, the more damage they can do. You can't get rid of tartar by brushing and flossing — you need a professional dental cleaning to remove it.
• Plaque can cause gingivitis, the mildest form of periodontal disease. Gingivitis is irritation and inflammation of the part of your gum around the base of your teeth (gingiva). Gingivitis can be reversed with professional treatment and good home oral care.
• Ongoing gum inflammation can cause periodontitis, eventually causing pockets to develop between your gums and teeth that fill with plaque, tartar and bacteria. In time, these pockets become deeper, filling with more bacteria. If not treated, these deep infections cause a loss of tissue and bone, and ultimately you may lose one or more teeth. Also, ongoing chronic inflammation can put a strain on your immune system.

Diagnosis

To determine whether you have periodontitis and how severe it is, your dentist may:

• Review your medical history to identify any factors that could be contributing to your symptoms, such as smoking or taking certain medications that cause dry mouth.
• Examine your mouth to look for plaque and tartar buildup and check for easy bleeding.
• Measure the pocket depth of the groove between your gums and teeth by placing a dental probe beside your tooth beneath your gumline, usually at several sites throughout your mouth. In a healthy mouth, the pocket depth is usually between 1 and 3 millimeters (mm). Pockets deeper than 4 mm may indicate periodontitis. Pockets deeper than 6 mm cannot be cleaned well.
• Take dental X-rays to check for bone loss in areas where your dentist observes deeper pocket depths.

Complications

Periodontitis can cause tooth loss. And some research suggests that the bacteria responsible for periodontitis can enter your bloodstream through gum tissue, possibly affecting your heart, lungs and other parts of your body. For example, periodontitis may be linked with respiratory disease, rheumatoid arthritis, coronary artery disease or stroke. But more studies are needed to confirm a link.

Prevention

The best way to prevent periodontitis is to follow a program of good oral hygiene, one that you begin early and practice consistently throughout life.

• Good oral hygiene. That means brushing your teeth for two minutes at least twice daily — in the morning and before going to bed — and flossing at least once a day. Flossing before you brush allows you to clean away the loosened food particles and bacteria.
• Regular dental visits. See your dentist or dental hygienist regularly for cleanings, usually every six to 12 months. If you have risk factors that increase your chance of developing periodontitis — such as having dry mouth, taking certain medications or smoking — you may need professional cleaning more often.

Lifestyle and home remedies

Try these measures to reduce or prevent periodontitis:

• Brush your teeth twice a day or, better yet, after every meal or snack.
• Use a soft toothbrush and replace it at least every three to four months.
• Consider using an electric toothbrush, which may be more effective at removing plaque and tartar.
• Floss daily.
• Use a mouth rinse to help reduce plaque between your teeth, if recommended by your dentist.
• Supplement brushing and flossing with an interdental cleaner, such as a dental pick, interdental brush or dental stick specially designed to clean between your teeth.
• Get regular professional dental cleanings, on a schedule recommended by your dentist.
• Don't smoke or chew tobacco.

Risk factors

Factors that can increase your risk of periodontitis include:

• Gingivitis
• Poor oral health habits
• Smoking or chewing tobacco
• Older age
• Hormonal changes, such as those related to pregnancy or menopause
• Substance abuse
• Obesity
• Inadequate nutrition, including vitamin C deficiency
• Genetics
• Certain medications that cause dry mouth or gum changes
• Conditions that cause decreased immunity, such as leukemia, HIV/AIDS and cancer treatment
• Certain diseases, such as diabetes, rheumatoid arthritis and Crohn's disease
