what is periodontal (gum) disease?
The term “periodontal”means “around the tooth.” Periodontal disease (also known as periodontitis and gum disease) is a common inflammatory condition which affects the supporting and surrounding soft tissues of the tooth; also the jawbone itself when in its most advanced stages.
Periodontal disease is most often preceded by gingivitis which is a bacterial infection of the gum tissue. A bacterial infection affects the gums when the toxins contained in plaque begin to irritate and inflame the gum tissues. Once this bacterial infection colonizes in the gum pockets between the teeth, it becomes much more difficult to remove and treat. Periodontal disease is a progressive condition that eventually leads to the destruction of the connective tissue and jawbone. If left untreated, it can lead to shifting teeth, loose teeth and eventually tooth loss.
Periodontal disease is the leading cause of tooth loss among adults in the developed world and should always be promptly treated.
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.
Types of Periodontal Disease
When left untreated, gingivitis (mild gum inflammation) can spread to below the gum line. When the gums become irritated by the toxins contained in plaque, a chronic inflammatory response causes the body to break down and destroy its own bone and soft tissue. There may be little or no symptoms as periodontal disease causes the teeth to separate from the infected gum tissue. Deepening pockets between the gums and teeth are generally indicative that soft tissue and bone is being destroyed by periodontal disease.
Here are some of the most common types of periodontal disease:
Chronic periodontitis – Inflammation within supporting tissues cause deep pockets and gum recession. It may appear the teeth are lengthening, but in actuality, the gums (gingiva) are receding. This is the most common form of periodontal disease and is characterized by progressive loss of attachment, interspersed with periods of rapid progression.
Aggressive periodontitis – This form of gum disease occurs in an otherwise clinically healthy individual. It is characterized by rapid loss of gum attachment, chronic bone destruction and familial aggregation.
Necrotizing periodontitis – This form of periodontal disease most often occurs in individuals suffering from systemic conditions such as HIV, immunosuppression and malnutrition. Necrosis (tissue death) occurs in the periodontal ligament, alveolar bone and gingival tissues.
Periodontitis caused by systemic disease – This form of gum disease often begins at an early age. Medical condition such as respiratory disease, diabetes and heart disease are common cofactors.
Treatment for Periodontal Disease
Periodontal treatment methods depend upon the type and severity of the disease. Your dentist and dental hygienist will evaluate for periodontal disease and recommend the appropriate treatment.
Periodontal disease progresses as the sulcus (pocket or space) between the tooth and gums gets filled with bacteria, plaque, and tartar, causing irritation to the surrounding tissues. When these irritants remain in the pocket space, they can cause damage to the gums and eventually, the bone that supports the teeth!
If the disease is caught in the early stages of gingivitis, and no damage has been done, one to two regular cleanings will be recommended. You will also be given instructions on improving your daily oral hygiene habits and having regular dental cleanings.
If the disease has progressed to more advanced stages, a special periodontal cleaning called scaling and root planing (deep cleaning) will be recommended. It is usually done one quadrant of the mouth at a time while the area is numb. In this procedure, tartar, plaque, and toxins are removed from above and below the gum line (scaling) and rough spots on root surfaces are made smooth (planing). This procedure helps gum tissue to heal and pockets to shrink. Medications, special medicated mouth rinses, and an electric tooth brush may be recommended to help control infection and healing.
If the pockets do not heal after scaling and root planing, periodontal surgery may be needed to reduce pocket depths, making teeth easier to clean. Your dentist may also recommend that you see a Periodontist (specialist of the gums and supporting bone).
Here are some of the more common treatments for periodontal disease:
Scaling and root planing – In order to preserve the health of the gum tissue, the bacteria and calculus (tartar) which initially caused the infection, must be removed. The gum pockets will be cleaned and treated with antibiotics as necessary to help alleviate the infection. A prescription mouthwash may be incorporated into daily cleaning routines.
Tissue regeneration – When the bone and gum tissues have been destroyed, regrowth can be actively encouraged using grafting procedures. A membrane may be inserted into the affected areas to assist in the regeneration process.
Pocket elimination surgery – Pocket elimination surgery (also known as flap surgery) is a surgical treatment which can be performed to reduce the pocket size between the teeth and gums. Surgery on the jawbone is another option which serves to eliminate indentations in the bone which foster the colonization of bacteria.
Dental implants – When teeth have been lost due to periodontal disease, the aesthetics and functionality of the mouth can be restored by implanting prosthetic teeth into the jawbone. Tissue regeneration procedures may be required prior to the placement of a dental implant in order to strengthen the bone.
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.
Four out of five people have periodontal disease and don’t know it! Most people are not aware of it because the disease is usually painless in the early stages.
Not only is it the number one reason for tooth loss, 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.
Common Causes of Gum Disease
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:
Poor dental hygiene - 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.
Tobacco use – 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.
Genetic predisposition – 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.
Pregnancy and menopause – 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.
Chronic stress and poor diet – 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.
Diabetes and underlying medical issues – 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.
Grinding teeth – 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.
Medication – 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.
Common Signs & Symptoms
It is extremely important to note that periodontal disease can progress without any signs or symptoms such as pain. This is why regular dental checkups are exceptionally important. Described below are some of the most common signs and symptoms of periodontitis.
If you have any of these signs or symptoms, the advice of a general dentist or periodontist should be sought as soon as possible:
Unexplained bleeding – Bleeding when brushing, flossing or eating food is one of the most common symptoms of a periodontal infection. The toxins in plaque cause a bacterial infection which makes the tissues prone to bleeding.
Pain, redness or swelling – A periodontal infection may be present if the gums are swollen, red or painful for no apparent reason. It is essential to halt the progression of the infection before the gum tissue and jaw bone have been affected. It is also critical to treat the infection before it is carried into the bloodstream to other areas of the body.
Longer-looking teeth – Periodontal disease can lead to gum recession. The toxins produced by bacteria can destroy the supporting tissue and bones, thus making the teeth look longer and the smile appear more “toothy.”
Bad breath/halitosis – Although breath odor can originate from back of the tongue, the lungs and stomach, from the food we consume, or from tobacco use, bad breath may be caused by old food particles which sit between the teeth and underneath the gumline. The deeper gum pockets are able to house more debris and bacteria, causing a foul odor.
Loose teeth/change in bite pattern – A sign of rapidly progressing periodontitis is the loosening or shifting of the teeth in the affected area. As the bone tissue gets destroyed, teeth that were once firmly attached to the jawbone become loose or may shift in position.
Pus – Pus oozing from between the teeth is a definitive sign that a periodontal infection is in progress. The pus is a result of the body trying to fight the bacterial infection.
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 on a daily basis will be removed from above and below the gum line.
In addition to your periodontal cleaning and evaluation, your appointment will usually include:
Examination of diagnostic x-rays (radiographs): Essential for detection of decay, tumors, cysts, and bone loss.X-rays also help determine tooth and root positions.
Oral cancer screening: Check the face, neck, lips, tongue, throat, cheek tissues, and gums for any signs of oral cancer.
Oral hygiene recommendations: Review and recommend oral hygiene aids as needed. (Electric toothbrushes, special periodontal brushes, fluorides, rinses, etc.)
Good oral hygiene practices and periodontal cleanings are essential in maintaining dental health and keeping periodontal disease under control!
