What is gum disease? Learn more about periodontal disease and how your Edmonton dentist at Today's Dental can help.
The word periodontal means "around the tooth". Periodontal disease attacks the gums and the bone that support the teeth. Plaque is a sticky film of food debris, bacteria, and saliva. If plaque is not removed, it turns into calculus (tartar). When plaque and calculus are not removed, they begin to destroy the gums and bone. Periodontal disease is characterized by red, swollen, and bleeding gums.
Periodontal disease can cause tooth loss, and research suggests that there may be a link between periodontal disease and other diseases such as, stroke, bacterial pneumonia, diabetes, cardiovascular disease, and increased risk during pregnancy. Researchers are determining if inflammation and bacteria associated with periodontal disease affects these systemic diseases and conditions. Smoking also increases the risk of periodontal disease. Good oral hygiene, a balanced diet, and regular dental visits can help reduce your risk of developing periodontal disease.
Periodontal (gum) disease, which is also known as periodontal disease and periodontitis, is a progressive disease which if left untreated may result in tooth loss. Gum disease begins with the inflammation and irritation of the gingival tissues which surround and support the teeth. The cause of this inflammation is the toxins found in plaque which cause an ongoing bacterial infection.
The bacterial infection colonizes in the gingival tissue and deep pockets form between the teeth and the gums. If treated promptly, the effects of mild inflammation (known as gingivitis) are completely reversible. However, if the bacterial infection can progress, periodontal disease begins to destroy the gums and the underlying jawbone; promoting tooth loss. In some cases, the bacteria from this infection can travel to other areas of the body via the bloodstream.
There are genetic and environmental factors involved in the onset of gum disease, and in many cases the risk of developing periodontitis can be significantly lowered by taking preventative measures.
Here are some of the most common causes of gum disease:
Preventing dental disease starts at home with good oral hygiene and a balanced diet. Prevention also includes regular dental visits which include exams, cleanings, and x-rays. A combination of excellent home care and professional dental care will ensure and preserve the natural dentition and supporting bony structures. When bacteria and calculus (tartar) are not removed, the gums and bone around the teeth become affected by bacteria toxins and can cause gingivitis or periodontitis, which can lead to tooth loss.
Research has indicated that smoking and tobacco use is one of the most significant factors in the development and progression of gum disease. In addition to smokers experiencing a slower recovery and healing rate, smokers are far more likely to suffer from calculus (tartar) build up on teeth, deep pockets in the gingival tissue and significant bone loss.
Despite practicing rigorous oral hygiene routines, as much as 30% of the population may have a strong genetic predisposition to gum disease. These individuals are six times more likely to develop periodontal disease than individuals with no genetic predisposition. Genetic tests can be used to determine susceptibility and early intervention can be performed to keep the oral cavity healthy.
During pregnancy, regular brushing and flossing is critical. Hormonal changes experienced by the body can cause the gum tissue to become more sensitive, rendering them more susceptible to gum disease.
Stress lowers the ability of the immune system to fight off disease, which means bacterial infections may possibly beat the body’s defense system. Poor diet or malnutrition can also lower the body’s ability to fight periodontal infections, as well as negatively affecting the health of the gums.
Many medical conditions can intensify or accelerate the onset and progression of gum disease including respiratory disease, heart disease, arthritis and osteoporosis. Diabetes hinders the body’s ability to utilize insulin which makes the bacterial infection in the gums more difficult to control and cure.
The clenching or grinding of the teeth can significantly damage the supporting tissue surrounding the teeth. Grinding one’s teeth is usually associated with a “bad bite” or the misalignment of the teeth. When an individual is suffering from gum disease, the additional destruction of gingival tissue due to grinding can accelerate the progression of the disease.
Many drugs including oral contraceptive pills, heart medicines, anti-depressants and steroids affect the overall condition of teeth and gums; making them more susceptible to gum disease. Steroid use promotes gingival overgrowth, which makes swelling more commonplace and allows bacteria to colonize more readily in the gum tissue.
Periodontal disease is diagnosed by your dentist or dental hygienist during a periodontal examination. This type of exam should always be part of your regular dental check-up.
A periodontal probe (small dental instrument) is gently used to measure the sulcus (pocket or space) between the tooth and the gums. The depth of a healthy sulcus measures three millimeters or less and does not bleed. The periodontal probe helps indicate if pockets are deeper than three millimeters. As periodontal disease progresses, the pockets usually get deeper.
Your dentist or hygienist will use pocket depths, amount of bleeding, inflammation, tooth mobility, etc., to make a diagnosis that will fall into a category below:
Gingivitis is the first stage of periodontal disease. Plaque and its toxin by-products irritate the gums, making them tender, inflamed, and likely to bleed.
Plaque hardens into calculus (tartar). As calculus and plaque continue to build up, the gums begin to recede from the teeth. Deeper pockets form between the gums and teeth and become filled with bacteria and pus. The gums become very irritated, inflamed, and bleed easily. Slight to moderate bone loss may be present.
The teeth lose more support as the gums, bone, and periodontal ligament continue to be destroyed. Unless treated, the affected teeth will become very loose and may be lost. Generalized moderate to severe bone loss may be present.
How do you maintain healthy gums?
It only takes twenty-four hours for plaque that is not removed from your teeth to turn into calculus (tartar). Daily home cleaning helps control plaque and tartar formation, but those hard to reach areas will always need special attention.
Once your periodontal treatment has been completed, your dentist and dental hygienist will recommend that you have regular maintenance cleanings (periodontal cleanings), usually four times a year. At these cleaning appointments, the pocket depths will be carefully checked to ensure that they are healthy. Plaque and calculus that is difficult for you to remove daily will be removed from above and below the gum line.
Research studies have shown that there is a strong association between periodontal disease and other chronic conditions such as diabetes, heart disease, pregnancy complications and respiratory disease.
Periodontal disease is characterized by chronic inflammation of the gum tissue, periodontal infection below the gum line and a presence of disease-causing bacteria in the oral region. Halting the progression of periodontal disease and maintaining excellent standards of oral hygiene will not only reduce the risk of gum disease and bone loss, but also reduce the chances of developing other serious illnesses.
Common co-factors associated with periodontal disease:
A research study has shown that individuals with pre-existing diabetic conditions are more likely to either have or be more susceptible to periodontal disease. Periodontal disease can increase blood sugar levels which makes controlling the amount of glucose in the blood difficult. This factor alone can increase the risk of serious diabetic complications. Conversely, diabetes thickens blood vessels and therefore makes it harder for the mouth to rid itself of excess sugar. Excess sugar in the mouth creates a breeding ground for the types of oral bacteria that cause gum disease.
There are several theories which explain the link between heart disease and periodontitis. One such theory is that the oral bacteria strains which exacerbate periodontal disease attach themselves to the coronary arteries when they enter the bloodstream. This in turn contributes to both blood clot formation and the narrowing of the coronary arteries, possibly leading to a heart attack.
A second possibility is that the inflammation caused by periodontal disease causes a significant plaque to build up. This can swell the arteries and worsen pre-existing heart conditions. An article published by the American Academy of Periodontology suggests that patients whose bodies react to periodontal bacteria have an increased risk of developing heart disease.
Women in general are at increased risk of developing periodontal disease because of hormone fluctuations that occur during puberty, pregnancy and menopause. Research suggests that pregnant women suffering from periodontal disease are more at risk of preeclampsia and delivering underweight, premature babies.
Periodontitis increases levels of prostaglandin, which is one of the labor-inducing chemicals. Elevated levels prostaglandin may trigger premature labour and increase the chances of delivering an underweight baby. Periodontal disease also elevates C-reactive proteins (which have previously been linked to heart disease). Heightened levels of these proteins can amplify the inflammatory response of the body and increase the chances of preeclampsia and low birth weight babies.
Oral bacterium linked with gum disease has been shown to possibly cause or worsen conditions such as emphysema, pneumonia and Chronic Obstructive Pulmonary Disease (COPD). Oral bacteria can be drawn into the lower respiratory tract during normal inhalation and colonize; causing bacterial infections. Studies have shown that the repeated infections which characterize COPD may be linked with periodontitis.In addition to the bacterial risk, inflammation in gum tissue can lead to severe inflammation in the lining of the lungs, which aggravates pneumonia. Individuals who suffer from chronic or persistent respiratory issues generally have low immunity. This means that bacteria can readily colonize beneath the gum line unchallenged by body’s immune system.
