What is Periodontal Disease?
Periodontal disease (also known as periodontitis and gum disease) is a progressive disease which affects the supporting and surrounding tissue of the gums, and the underlying jawbone. If left untreated, periodontal disease can result in loose, unstable teeth, and even tooth loss. Periodontal disease is in fact the leading cause of tooth loss in adults in the developed world and should not be taken lightly.
Periodontal disease (also known as periodontitis and gum disease) is a progressive condition and the leading cause of tooth loss amongst adults in the developed world. Periodontal disease occurs when the toxins found in plaque begin to irritate or inflame the gingiva (gum tissue). The resulting bacterial infection often known as gingivitis, can eventually lead to the destruction of the gum tissue and underlying bone. If periodontal disease is not treated, it can also lead to loose teeth or tooth loss.
Types of Gum Disease
Periodontal disease begins when the toxins found in plaque start to attack the soft or gingival tissue surrounding the teeth. This bacterium embeds itself in the gum and rapidly breeds, causing a bacterial infection. As the infection progresses, it starts to burrow deeper into the tissue causing inflammation or irritation between the teeth and gums. The response of the body is to destroy the infected tissue, which is why the gums appear to recede. The resulting pockets between the teeth deepen and, if no treatment is sought, the tissue which makes up the jawbone also recedes causing unstable teeth and tooth loss.
There are many different varieties of periodontal disease, and many ways in which these variations manifest themselves. All require immediate treatment by a periodontist to halt the progression and save the gum tissue and bone. Here are some of the most common types of periodontal disease along with the treatments typically performed to correct them:
Gingivitis is the mildest and most common form of periodontitis. It is caused by the toxins in plaque and leads to periodontal disease. People at increased risk of developing gingivitis include pregnant women, women taking birth control pills, people with uncontrolled diabetes, steroid users and people who control seizures and blood pressure using medication.
Gingivitis is easily reversible using a solid combination of home care and professional cleaning. The dentist may perform root planing and deep scaling procedures to cleanse the pockets of debris. A combination of antibiotics and medicated mouthwashes may be used to kill any remaining bacteria and promote the good healing of the pockets.
Chronic Periodontal Disease
Chronic periodontal disease is the most common form of the disease, and occurs much more frequently in people over 45. Chronic periodontal disease is characterized by inflammation below the gum line and the progressive destruction of the gingival and bone tissue. It may appear that the teeth are gradually growing in length, but in actuality the gums are gradually recessing.
Unfortunately unlike gingivitis, chronic periodontal disease cannot be completely cured because the supportive tissue cannot be rebuilt. However, the dentist can halt the progression of the disease using scaling and root planing procedures in combination with antimicrobial treatments. If necessary, the periodontist can perform surgical treatments such as pocket reduction surgery and also tissue grafts to strengthen the bone and improve the aesthetic appearance of the oral cavity.
Aggressive Periodontal Disease
Aggressive periodontal disease is characterized by the rapid loss of gum attachment, the rapid loss of bone tissue and familial aggregation. The disease itself is essentially the same as chronic periodontitis but the progression is much faster. Smokers and those with a family history of this disease are at an increased risk of developing aggressive periodontitis.
The treatments for aggressive periodontal disease are the same as those for chronic periodontal disease, but aggressive periodontal disease sufferers are far more likely to require a surgical intervention. This form of the disease is harder to halt and treat, but the dentist will perform scaling, root planing, antimicrobial, and in some cases laser procedures in an attempt to save valuable tissue and bone.
Periodontal Disease Relating to Systemic Conditions
Periodontal disease can be a symptom of a disease or condition affecting the rest of the body. Depending on the underlying condition, the disease can behave like aggressive periodontal disease, working quickly to destroy tissue. Heart disease, diabetes and respiratory disease are the most common co-factors, though there are many others. Even in cases where little plaque coats the teeth, many medical conditions intensify and accelerate the progression of periodontal disease.
Treatment: Initially, the medical condition which caused the onset of periodontal disease must be controlled. The dentist will halt the progression of the disease using the same treatments used for controlling aggressive and chronic periodontal disease.
Necrotizing Periodontal Disease
This form of the disease rapidly worsens and is more prevalent among people who suffer from HIV, immunosuppression, malnutrition, chronic stress or choose to smoke. Tissue death (necrosis) frequently affects the periodontal ligament, gingival tissues and alveolar bone.
Treatment: Necrotizing periodontal disease is extremely rare. Because it may be associated with HIV or another serious medical condition, it is likely the dentist will consult with a physician before commencing treatment. Scaling, root planing, antibiotic pills, medicated mouth wash and fungicidal medicines are generally used to treat this form of the disease.
If you have any question or concerns about the different types of periodontal disease and treatments, please ask your dentist.
Common Signs & Symptoms of Gum Disease
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.
Diagnosing Gum Disease
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, and other measurements to make a diagnosis that will fall into a category below:
- Gingivitis – 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.
- Periodontitis – 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.
- Advanced Periodontitis – 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.
Treatment for Periodontal Disease
There are many surgical and nonsurgical treatments the periodontist may choose to perform, depending upon the exact condition of the teeth, gums and jawbone. A complete periodontal exam of the mouth will be done before any treatment is performed or recommended.
Some of the more common treatments for periodontal disease include:
- 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.
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.
Some of the most common causes of gum disease include:
- 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.
- Teeth grinding – 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.
