15: Periodontics: Gums and Bone Surrounding Teeth

CHAPTER 15 Periodontics

Gums and Bone Surrounding Teeth

Periodontics is an area of dentistry that has been neglected significantly by both dentists and patients. this area of dentistry involves the supporting structures of the teeth, primarily the bone of the jaws and the gum tissue. During adulthood, more teeth are lost to periodontal disease than to dental caries (decay). Why has periodontal therapy been neglected? the most important reason is that disease of the gums and bone progresses slowly and usually is not painful. Most patients do not seek treatment for periodontal disease unless they are motivated by their dentist or dental hygienist. The majority of general dentists emphasize other parts of dental practices, such as restoring teeth (fillings), and they do not motivate patients to seek treatment of periodontal disease.

Although many diseases affect the gums and bone tissues, two are most common: gingivitis and periodontitis. Gingivitis is simply gum infiammation, not affecting the bone, whereas periodontitis involves degeneration of the bone structure as well as gum infiammation.

Numerous signs and symptoms of periodontal disease (discussed later) are evident to knowledgeable dental patients. Changes in the bone and gums of the jaw may indicate ongoing degeneration and reduction of bone support for teeth and may require professional help. There are dentists who specialize in periodontal therapy (periodontists) in most cities with a significant population; many general dentists also provide periodontal treatment. Patients who think that they have some form of periodontal disease should ask their general dentist or dental hygienist about the health of their gums and supporting structures. If disease is present beyond the level that the general dentist prefers to treat, the general dentist should refer his or her patient to a periodontist.

Conditions, Signs, or Symptoms Related to Periodontics

2. Red Gums

(FIG. 15.2). Gum tissue that appears to be redder than normal is usually infiamed and engorged with blood, and the gums may bleed when stimulated. Red gums may be caused by numerous conditions, including frequent mouth breathing that leaves a sticky residue on teeth surfaces, leaving food debris on teeth and gum surfaces for prolonged periods, excessive smoking, or drinking of alcoholic beverages, or presence of long-term gum and bone breakdown that have caused increased blood in the gum tissue.

It is difficult for patients to determine the cause of red gums, but a dentist or dental hygienist should be able to tell after an examination. The presence of red gums is usually an indicator of disease activity. One or more of the following methods should be used to treat it:

3. Creamy, Yellow Substance Comes From Space Between Tooth and Gums; Foul Odor is Present

(FIG. 15.3). Pus discharge from beneath the gums is a nearly sure sign of advanced periodontal disease (gum and bone degeneration) involving the supporting bone tissue. Pus is food debris, dead cells, and microorganisms (bacteria), and is a sign that infection is present. Stimulation of such gums by eating hard foods or cleaning the teeth can cause the infection to be carried to other parts of the body via the blood (bacteremia). Pus discharge can cause disagreeable mouth odors evident to others close enough to smell the breath. When oral disease is present to this degree, it should be treated as soon as possible to avoid further periodontal breakdown. Although such treatment is more difficult than therapy for less advanced periodontal disease, in most cases teeth can still be saved and effectively used for many years. Alternatives for treatment include the following:

D. Tooth extraction (p. 92) and placement of artificial tooth replacements (p. 61)

4. Gums Have Receded From Original Adult Level and Are Unsightly or Sensitive

(FIG. 15.4). Over a lifetime, gum tissue slowly recedes naturally, even with healthy and acceptable periodontal structures. Your gums may have receded naturally, and your mouth may be completely normal and healthy for your age. In such situations the gums are pink and firm, and the teeth are strong and immobile when pressure is applied.

Gum tissue may also recede when periodontal disease is present if it has caused significant bone destruction to reduce tooth support (FIG. 15.5). If periodontal disease is present, visible tooth movement may be observed when teeth are moved forward and backward. Tooth roots will be exposed when gums and bone have receded. Tooth roots are a darker color than tooth crowns (enamel-covered portion of the teeth). The point at which the darker root joins the lighter crown of the tooth is the original location of the gums on the tooth for an adult (FIG. 15.6). Root surfaces may be sensitive to touch, hot and cold foods, or cold air. The two colors of the tooth when the gums have receded may look objectionable to you; therefore, there are two separate potential problems related to receded gums: (A) tooth sensitivity, and (B) disagreeable appearance. The following treatment alternatives are available:
