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.
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
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.
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 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.
Factors that can increase your risk of periodontitis include:
Poor oral health habits
Smoking or chewing tobacco
Hormonal changes, such as those related to pregnancy or menopause
Inadequate nutrition, including vitamin C deficiency
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
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.
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.
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.
Treatment may be performed by a periodontist, a dentist or a dental hygienist. The goal of periodontitis treatment is to thoroughly clean the pockets around teeth and prevent damage to the surrounding bone. You have the best chance for successful treatment when you also adopt a daily routine of good oral care and stop tobacco use.
If periodontitis isn't advanced, treatment may involve less invasive procedures, including:
Scaling. Scaling removes tartar and bacteria from your tooth surfaces and beneath your gums. It may be performed using instruments, a laser or an ultrasonic device.
Root planing. Root planing smoothes the root surfaces, discouraging the further buildup of tartar and bacteria, and removes bacterial byproducts that contribute to inflammation and delay healing or reattachment of the gum to the tooth surfaces.
Antibiotics. Topical or oral antibiotics can help control bacterial infection. Topical antibiotics can include antibiotic mouth rinses or insertion of gels containing antibiotics in the space between your teeth and gums or into pockets after deep cleaning. However, oral antibiotics may be necessary to completely eliminate infection-causing bacteria.
If you have advanced periodontitis, treatment may require dental surgery, such as:
Flap surgery (pocket reduction surgery). Your periodontist makes tiny incisions in your gum so that a section of gum tissue can be lifted back, exposing the roots for more effective scaling and root planing. Because periodontitis often causes bone loss, the underlying bone may be recontoured before the gum tissue is sutured back in place. After you heal, it's easier to clean these areas and maintain healthy gum tissue.
Soft tissue grafts. When you lose gum tissue, your gumline recedes. You may need to have some of the damaged soft tissue reinforced. This is usually done by removing a small amount of tissue from the roof of your mouth (palate) or another donor source and attaching it to the affected site. This can help reduce further gum recession, cover exposed roots and give your teeth a more pleasing appearance.
Bone grafting. This procedure is performed when periodontitis has destroyed the bone surrounding your tooth root. The graft may be composed of small fragments of your own bone, or the bone may be synthetic or donated. The bone graft helps prevent tooth loss by holding your tooth in place. It also serves as a platform for the regrowth of natural bone.
Guided tissue regeneration. This allows the regrowth of bone that was destroyed by bacteria. In one approach, your dentist places a special piece of biocompatible fabric between existing bone and your tooth. The material prevents unwanted tissue from entering the healing area, allowing the bone to grow back instead.
Tissue-stimulating proteins. Another technique involves applying a special gel to a diseased tooth root. This gel contains the same proteins found in developing tooth enamel and stimulates the growth of healthy bone and tissue.
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.
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.
