Periodontists and Periodontics 101, Dental Specialties
Periodontics is one of the eight dental specialties recognized by the American Dental Association. Periodontists specialize in Periodontal work. Periodontal comes from two Greek words that mean "around the tooth." The periodontium refers to the anatomical structures around teeth: the gum, bone, and the periodontal ligament that attaches the tooth to the bone.
Periodontists are dentists that have three additional years of training to specialize in the prevention, diagnosis, and treatment of the diseases that affect the gums and supporting structures of the teeth. Periodontists also are experts in the placement and treatment of dental implants.
Periodontal disease is the major cause of tooth loss in adults. According to the American Dental Association, three out of four Americans over age 35 have some form of periodontal disease. Gingivitis is the mildest form of periodontal disease and the most common infection in the world. But if left untreated, it can progress to periodontitis -- the loss of bone and tissues that support the teeth.
Periodontal diseases can be localized to a few teeth or generalized, in which most of the teeth are affected. It can affect people of all ages and without proper periodontal treatment, this disease can result in tooth loss and even complications of systemic diseases.
There are several different forms of periodontal disease. Each can progress at different rates. The same disease can have periods when it develops slowly and others when it progresses quite rapidly. Most of the time, periodontal diseases are painless. But they may have acute episodes that result in severe pain and a dental emergency.
The rate of periodontal disease progression is dependent on a multitude of factors, including the presence of certain risk factors that make people more susceptible to periodontal breakdown.
All periodontal disease is caused by an accumulation of bacteria at and below the gum line. The bacteria release toxic substances that trigger the breakdown of the gum and bone. The gums become red, swollen, and bleed easily. The gum tissue then separates from the teeth, forming a gap called a periodontal pocket or exposing the root surface in what is called recession.
The body responds to the bacteria with an inflammatory response in which it essentially 'turns on itself' and destructs the bone and tissues around the teeth. This is the body's way of warding off infectious agents. The teeth can start moving and shifting and eventually if there is advanced bone loss, the teeth can be lost.
Periodontal diseases are treated in three phases by periodontists. The first is to stop the disease activity and progression of bone loss. In the early stages of periodontal disease, scaling and root planning may be the only treatment needed.
The bacterial deposits (plaque and tartar) that formed above and underneath the gums need to be removed and the root surfaces of the teeth smoothed to enhance healing and deter future plaque retention. During this phase of treatment, the periodontist will review the oral hygiene technique, and give advice on the modification of certain risk factors associated with periodontal disease.
If the periodontal disease is more advanced, surgical treatment may be indicated. The purpose of this phase of treatment is to create an environment that is more amenable to health and, if possible, regenerate some of the bone that was lost to the disease.
In some forms of periodontitis, antibiotic treatment may be indicated. If this is the case, a bacterial culture may be required to test for harmful bacteria and to establish what antibiotics they are susceptible to.
Periodontal disease is a chronic disease that, like many other chronic diseases, has to be closely monitored, even after active treatment. The maintenance or third phase is crucial to the success of any treatment.
Daily brushing and flossing is essential in controlling the ever-developing plaque. So is periodic periodontal maintenance care with a Periodontists scaling of the teeth. The periodontal status has to be closely monitored so that changes can be identified and treated as early as possible.
Everyone should be routinely screened for periodontal disease. All periodontists are qualified in detecting and treating the early stages of periodontal disease, but if you suspect that you are at risk, or you know you have periodontal disease, you may want to see a periodontist who has extensive advanced training in the diagnoses and treatment of periodontal diseases.
With today's Periodontists knowledge about periodontal diseases and the new advances in treatment, you can expect to keep your teeth for a lifetime and ward off the effects that periodontal disease may have on your overall health.

Smoking and Gum Disease
The systemic risks of tobacco use are well known. Tobacco use can increase the risk for cancer, lung disease, and heart disease. But whether you smoke, dip, or chew tobacco, it also affects the oral cavity in a variety of ways. It contributes to oral cancer, stains the teeth, and contributes to tartar deposits, bad breath, and a loss of taste and smell.
Tobacco use causes inflammation of the soft tissues of the mouth, ulcers, recession, and other oral lesions. Tobacco users are two times more likely to develop periodontitis, and ten times more likely to develop acute necrotizing ulcerative gingivitis (ANUG). They also are more likely to lose teeth than those who don't smoke. Smoking is the number one most significant risk factor in the development and progression of periodontal disease.
Tobacco smoking causes periodontal bone loss that is not related to the amount of gum inflammation or plaque accumulation. Although the periodontal disease may be advanced, the classical signs of gum inflammation (redness, bleeding gums, etc.) are not usually as evident in tobacco smokers. Thus, prevention and early detection are more difficult.
Tobacco smoking has a direct effect on the oral tissues and it can alter the immune response. Although smokers do benefit from periodontal treatment, the healing is often delayed and the results are less predictable. In addition, the success rates of periodontal and implant treatment are reduced in people who use tobacco products. The amount of complications is related to the amount of daily tobacco exposure, and the number of years the person has been exposed.
The use of tobacco products can increase the risk of periodontal disease:
1. It weakens the immune system: Tobacco products suppress the body's ability to fight infection. Carbon monoxide (a major byproduct of cigarette smoke) reduces oxygen concentration and inhibits the movement of white blood cells. This reduces the capacity of the white blood cells to fight bacteria (including the bacteria that cause periodontal disease), and delays healing.
2. It masks signs of infection: Tobacco reduces the ability of blood vessels to carry infection fighting cells, nutrients, and oxygen to the tissues. As a result, the typical signs of periodontal disease (redness, swelling, and bleeding of the gums) are masked. People who smoke may have periodontal disease that is harder to diagnose.
3. It increases calculus formation: Smoking can cause more calculus (tartar) accumulation that if not removed promptly can lead to more plaque build-up and periodontal disease.
4. It reduces healing: Nicotine and other chemicals can be absorbed directly by the root surfaces of the teeth and reduce the ability of cells to reattach to the root surface during healing.
Besides the obvious health benefits of discontinuing tobacco use, quitting can also reduce the risk of oral cancer and the detrimental effects of tobacco on the gums and bone that support the teeth. In addition, another incentive to stop smoking is that former smokers respond similarly to never smokers to periodontal treatment.
Because there is a physical and psychological addiction to tobacco, quitting can be very difficult. But millions of Americans quit smoking every year. There are aids available that reduce the craving for tobacco. These include the use of systemic medications, the nicotine patch, the nicotine gum, the nicotine inhaler, and the nasal spray. See your dentist or physician for aid in stopping tobacco use.
