Periodontal Disease: Preventing Tooth And Bone Loss
The best way to control periodontal disease and to help prevent tooth loss is with early detection and treatment. Three out of four people are afflicted by periodontal disease at some point in their lives, so everyone should be tested. After reviewing a patient's dental and medical history, the dental care provider or periodontist will conduct a thorough clinical intraoral exam called a periodontal charting.
This consists of taking a series of measurements around each tooth. Unless the gums are very inflamed and sensitive, the periodontal charting causes minimal discomfort.
The space between the gum and the tooth is measured using a periodontal probe. This space is called the probing or pocket depth. In a healthy mouth, this space should be between 0 and 3 millimeters.
The amount of recession or loss of gum around each tooth is measured. In healthy mouths, the gum tissue should be at the junction of where the crown of the tooth meets the root. The two measurements (pocket depth and recession) are then added to calculate the amount of attachment loss around each tooth. The greater the amount of attachment loss, the more advanced the periodontal disease.
While completing the periodontal charting, a dentist will evaluate the conditions of an individual's gums. Healthy gums are pale pink, firm, and immobile. The gums should not bleed during the probing exam. Bleeding gums during this exam are a sign of gum inflammation, gingivitis or periodontitis.
The dentist will also measure tooth mobility. Under normal functional conditions, teeth should not move. Tooth mobility is a sign that there has been bone loss around the teeth or that the biting forces are too strong. If so, the dentist may also assess a patient's occlusion, or bite. If the bite has changed or if the forces on the teeth are too strong, there may be an acceleration of bone loss around the teeth.
A full mouth series of X-rays (approximately 20 films) are also indispensable in a periodontal examination.
In addition to identifying areas with cavities, bone infection, tumors, or developmental abnormalities, X-rays help reveal if bone loss has resulted from periodontal disease. The crest of the teeth's supporting bone is normally 2 mm below where the crown of the tooth meets the root. A greater distance indicates a history of bone loss.
Although bacterial samples are not usually taken for diagnosis of periodontal disease , under certain circumstances, it may be necessary to take a bacterial culture from a plaque sample. This is especially valuable to help detect sites at high risk for disease progression or if conventional treatment is not working.
The culture is analyzed in a laboratory for the presence of certain bacteria that are known to contribute to gum disease. Actually, of the more than 300 different types of bacteria normally found in the mouth, there are only about 13 that are known to be associated with causing periodontal disease. After identifying the specific disease-causing bacteria, the laboratory can test to determine what antibiotics they are susceptible to.
Depending on the risk factors (see article " Risk Factors for Periodontal Disease") involved and a person's specific situation, other tests may also be required. Under certain circumstances, a dentist may require diagnostic casts (molds of one's teeth), medical laboratory tests, medical consultation, or genetic testing.
After completing the periodontal examination, the dentist will be able to discuss with the patient the diagnosis, treatment alternatives, potential complications, and expected results. The key to long-term periodontal health is early diagnosis and treatment. Because everyone is at risk of developing periodontitis, everyone should be routinely tested.

Gum Disease and Early Diabetes Detection
In many cases it's the dentist - and not the physician - who has the first opportunity to detect diabetes early, because diabetics are especially prone to dental health problems.
Swollen, tender, receding and bleeding gums, loose teeth, and a sore tongue may not just be signs of poor dental hygiene. They may be danger signals for diabetes, too.
If you have any of these symptoms, you may be one of the estimated 11 million people in North America who already have diabetes, or you may be one of the 600,000 who will be diagnosed this year.
Diabetes occurs when a gland called the pancreas fails to produce sufficient amounts of the hormone, insulin, to regulate blood sugar levels. In other words: Diabetics have too little insulin and too much sugar in their blood.
When this happens, the body tissue can't convert the sugar it needs into energy. The blood stream then fills with this unused sugar and the result is diabetes - a disease medical journals often describe as the "forever" disease.
A serious illness which respects neither age, sex, race nor income level, diabetes is the leading cause of blindness in people 20 to 65 years old and can lead to kidney failure, heart attacks and even death.
But outside the dental community, few people realize that diabetics have more than their share of tooth and periodontal (gum) problems. This fact is especially true for undiagnosed diabetics or those who have failed to control their disease adequately with insulin and/or diet and exercise.
Periodontal disease among diabetics progresses rapidly, recurs frequently, and heals slowly. The resistance to treatment can lead to loosened teeth and premature tooth loss.
Your regular dental office visits provide the best chance for early detection of many health problems, including diabetes. If you have a diabetic tendency, your dentist may very well refer you to your physician - another good reason to keep your prescribed dental recall and dental cleaning appointments faithfully!
If you are diabetic, it's important that you keep your dental health history up-to-date, exercise regularly, and eat a diet that provides good nutrition:
- Have regular meals and snack times. Don't skip meals.
- Avoid sweets (cake, candy, pie, ice cream).
- Limit use of animal fats and trim fat off meats. Avoid butter, cream, egg yolks.
- Bake and broil rather than fry foods.
- Don't use alcohol, wine, or beer without your doctor's permission.
- See your dentist regularly so small dental problems can be taken care of with a local anesthetic.
Teeth don't heal themselves, so small problems turn into big ones if left untreated. Major oral surgery requires a general anesthetic which means "no food prior to surgery" - a problem for diabetics.
