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.

Dental Disease And Ridge Augmentation

Whether a tooth has been lost to periodontal disease, tooth decay, or trauma, one may be left with a cleft, an indentation, or uneven gum margins. This happens because after a tooth is removed, the bone that was encasing it disintegrates and the gum around it collapses. If this occurs in the front of the mouth, it can result in an esthetic problem. No matter how well designed the replacement teeth are, they may appear to be too long and unattractive. To have a pleasing smile, the shape, color, and texture of the gums is just as important as that of the teeth they frame.

Ridge augmentation is a cosmetic periodontal procedure that may include gum and/or bone grafting. A dentist will determine which option is better suited to a patient's esthetic needs. Regardless of what treatment method a dentist chooses, ridge augmentation is a very predictable procedure with long-lasting results.

What to Expect from Periodontal Ridge Augmentation

Ridge augmentation is a surgical procedure that is done in the dentist's office with local anesthesia (lidocaine). Stitches (sutures) are placed to aid in healing. Post-surgical discomfort can last a few days and is usually minimal. It can be easily managed with commonly available over-the-counter medications such as aspirin, acetaminophen, or ibuprofen. Patients can expect to follow their normal routine the day after oral surgery. The dentist will provide special instructions related to diet, exercise and medications.

To ensure more esthetic results, ridge augmentation procedures should always be done before new crowns are made. Although a temporary (provisional) tooth replacement can be made at the time of tooth loss, the final restoration should not be fabricated until after six to eight weeks of gum healing.

Alternatives periodontal treatments

It is possible to help prevent collapse of the gum tissue by doing a bone grafting procedure or by placing an implant at the time of extraction. Although sometimes it may still be necessary to do further periodontal plastic surgery procedures, these treatments can help maintain the space that was previously occupied by the tooth and prevent bone loss. If this was not feasible, ridge augmentation can be done to improve esthetics after tooth extraction.

Ridge augmentation should be considered as part of an individual's cosmetic dentistry options when there are uneven gum contours, clefts, or indentations on the gums. The most beautiful teeth will not look natural if the gum surrounding them is not cosmetically pleasing. Talk to a dentist about esthetic concerns and the possibility of incorporating cosmetic periodontal procedures as part of a "smile lift."
