Have you ever been told that you have or may get periodontal disease, yet did not quite understand what periodontal disease is? Ever wonder what the difference is between periodontal disease and another commonly used term of gingivitis? The answers to those questions will increase your awareness of two of the most commonly found conditions in man.
Periodontal disease is gum and bone disease around teeth. It is loss of bone and gum attachment around the teeth. The gums may or may not be inflamed once this loss of bone and gum attachment occurs. Generally this bone and attachment loss is irreversible. Gingivitis is gum inflammation around teeth with no attachment loss and no bone loss. Gingivitis is reversible if properly treated. Both periodontal disease and gingivitis are caused by bacterial plaque under the gums. Initially soft bacterial plaque, if not removed, eventually hardens to form calculus, which can irritate the gums. Many factors contribute to the bone and attachment loss seen in periodontal disease even though these contributing factors are not the primary cause of this disease.
There are also different types of periodontal disease. The most common form is the chronic type, which can go on for many years and give no pain. A less common type is the aggressive form which can occur at a younger age and progress more rapidly than the chronic form. Periodontal disease can be localized to one or more teeth, or be generalized to involve all or most of the teeth. Also the disease may be mild, moderate or advanced at one tooth or a number of teeth. More than one degree may be present, meaning that some areas may have a mild periodontal disease and other areas may have advanced periodontal disease.
There is a space around each tooth, between the gums and the tooth root. The top of the space is the top of the gums and the bottom of the space is the attachment of the gums to the tooth root, which in a healthy case, is on average at least 2 millimeters above the bone level in that area. This space, when deep, is often referred to as a “pocket” in dental offices. When bone is lost around teeth, deep spaces or pockets may develop around the teeth. Or in other cases the gums may recede with the bone loss, keeping the spaces below the gums shallow and exposing the roots.
Periodontal disease and gingivitis can be treated at your dental office. Depending on it’s severity and your general dentist, it may be treated at your general dentist office, a specialist’s ( periodontist ) office or at both offices. In topic #2, we will discuss the treatment of periodontal disease and gingivitis.
Basic gum treatment involves removal of dental calculus and plaque above and below the gums. Below the gums means removing the calculus and plaque from the pockets or spaces around the teeth. The depth of the pocket determines the access available to remove the calculus and plaque and therefore determines the optimum treatment needed to remove the calculus and plaque.
Normal cleanings are designed to remove calculus and plaque above the gum line and in shallow pockets or spaces under the gums. A limitation of normal cleanings is that this procedure does not remove all the plaque and calculus in the moderate or deep pockets (spaces) under the gum line. In these areas, the surface of the gums may improve for a short time, however the person is still at a high risk of losing more bone and gum attachment deep under the gums in areas where the plaque and calculus still remains.
For areas of moderate spaces, a procedure called scaling and root planning is needed. For deep spaces, gums are lifted for access and visibility and then put back in place for healing and reattachment to occur. This procedure is periodontal surgery.
Once the calculus and plaque is removed under the gums, a maintenance schedule of normal cleanings an average of every 3 to 6 months is required to prevent the plaque and calculus from forming deep under the gums and hardening there. If the maintenance schedule is not followed, then the benefits of the initial gum treatment are lost after a few years. Whether maintenance schedule should be every 3 or 4 or 5 or 6 months depends on the level of oral hygiene a person has and the resistance a person has to gum and bone (periodontal) disease.
The benefits of gum treatment are to reduce the risk of further bone and gum attachment loss around teeth and in some cases regain gum attachment and bone levels around teeth with certain types of gum or bone defects. If enough gum attachment and bone loss occurs around a tooth, the tooth becomes loose and can be lost in the future. Gum treatment in a timely manner can prevent or reduce the risk of tooth loosening and tooth loss. In cases where the initial bone loss is severe around the teeth, gum treatment may prolong the time that the teeth remains in the mouth compared to those teeth receiving no treatment at all.
Gum attachment and bone support around teeth are the foundations for the support of the teeth in the mouth. Without enough of this foundation of tooth support, all dental treatment that relies on adequate tooth support can fail prematurely. Examples of dental treatment that rely on adequate tooth support include crowns, bridges, partial dentures and fillings. Even implants rely on good bone levels around them. Also unless the gums are healthy around the teeth, regardless at which levels they are at, future quality of dental treatment is compromised and the average duration of the dental treatment is reduced. In other words, it is not possible for any dentist to do good quality crowns, bridges or fillings in areas where the gums bleed easily and have calculus above and below the gum line in those areas.
