Periodontal Disease
Mouth - Body Connection
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 cofactors associated with periodontal disease:
Diabetes
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.
Heart 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 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.
Pregnancy Complications
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 labor, 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.
Respiratory Disease
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 the course of 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.

Causes of 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 by a periodontist, the effects of mild inflammation (known as gingivitis) are completely reversible. However, if the bacterial infection is allowed to 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.
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.
Treatment of Gum Disease
Periodontists specialize in the treatment of gum disease and the placement of dental implants. A periodontist can perform effective cleaning procedures in deep pockets such as scaling and root planing, and also prescribe antibiotic and antifungal medications to treat infection and halt the progression of the disease.
In the case of tooth loss, the periodontist is able to perform tissue grafts to promote natural tissue regeneration, and insert dental implants if a tooth or several teeth are missing. Where gum recession causes a “toothy” looking smile, the periodontist can recontour the gingival tissue to create an even and aesthetically pleasing appearance.
Preventing periodontal disease is critical in preserving the natural dentition. Addressing the causes of gum disease and discussing them with your dentist will help prevent the onset, progression, and recurrence of periodontal disease.
If you have any questions or concerns about the causes or treatments pertaining to gum disease, please ask your dentist.
Signs and Symptoms of Periodontal Disease
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.
There are many common types of periodontal disease including aggressive, chronic, necrotizing periodontitis, and periodontitis associated with systemic diseases. Each of these types of periodontal disease has its own distinct characteristics and symptoms, and all require prompt treatment by a dentist to halt subsequent bone and tissue loss.
Common Signs and 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.
Treatment of Periodontal Disease
It is of paramount importance to halt the progression of periodontal disease before it causes further damage to the gum tissues and jawbone. The dentist will initially assess the whole mouth in order to ascertain the progress of the disease. When a diagnosis has been made, the dentist may treat the bacterial infection with antibiotics in conjunction with nonsurgical or surgical treatment or both.
In the case of moderate periodontal disease, the pockets (under the gumline) of the teeth will be completely cleared of debris using a procedure called scaling and root planing. The pockets may be filled with antibiotics to promote good healing and kill any bacteria that remain.
Severe periodontitis can be treated in several different ways, such as:
- Laser treatment - This can be used to reduce the size of the pockets between the teeth and the gums.
- Tissue and bone grafting - Where a considerable amount of bone or gum tissue has been destroyed, the dentist may elect to graft new tissue by inserting a membrane to stimulate tissue growth.
- Pocket elimination surgery - The dentist may choose to perform “flap surgery” to directly reduce the size of the gum pockets.
If you have any further questions about the signs and symptoms of periodontal disease, please ask your dentist.
Types of 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 also 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 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.
Types of Periodontal Disease
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
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.
Treatment: 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.
Treatment: 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.
Treatment: 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 cofactors, 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.
Treatment
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 planning (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 (planning). 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 planning, 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).
Periodontal Scaling and Root Planing
The objective of scaling and root planning is to remove etiologic agents which cause inflammation to the gingival (gum) tissue and surrounding bone. Common etiologic agents removed by this conventional periodontal therapy include dental plaque and tartar (calculus).
These non-surgical procedures which completely cleanse the periodontium, work very effectively for individuals suffering from gingivitis (mild gum inflammation) and moderate/severe periodontal disease.
Reasons for scaling and root planing
Scaling and root planning can be used both as a preventative measure and as a stand-alone treatment. These procedures are performed as a preventative measure for a periodontitis sufferer.
Here are some reasons why these dental procedures may be necessary:
- Disease prevention - The oral bacteria which cause periodontal infections can travel via the bloodstream to other parts of the body. Research has shown that lung infections and heart disease have been linked to periodontal bacteria. Scaling and root planing remove bacteria and halts periodontal disease from progressing, thus preventing the bacteria from traveling to other parts of the body.
- Tooth protection - When gum pockets exceed 3mm in depth, there is a greater risk of periodontal disease. As pockets deepen, they tend to house more colonies of dangerous bacteria. Eventually, a chronic inflammatory response by the body begins to destroy gingival and bone tissue which may lead to tooth loss. Periodontal disease is the number one cause of tooth loss in the developed world.
- Aesthetic effects - Scaling and root planing help remove tartar and plaque from the teeth and below the gumline. As an added bonus, if superficial stains are present on the teeth, they will be removed in the process of the scaling and root planning procedure.
- Better breath - One of the most common signs of periodontal disease is halitosis (bad breath). Food particles and bacteria can cause a persistent bad odor in the oral cavity which is alleviated with cleaning procedures such as scaling and root planing.
What do scaling and root planing treatments involve?
Scaling and root planing treatments are only performed after a thorough examination of the mouth. The dentist will take X-rays, conduct visual examinations and make a diagnosis before recommending or beginning these procedures.
Depending on the current condition of the gums, the amount of calculus (tartar) present, the depth of the pockets and the progression of the periodontitis, local anesthetic may be used.
Scaling - This procedure is usually performed with special dental instruments and may include an ultrasonic scaling tool. The scaling tool removes calculus and plaque from the surface of the crown and root surfaces. In many cases, the scaling tool includes an irrigation process that can also be used to deliver an antimicrobial agent below the gums that can help reduce oral bacteria.
Root Planing - This procedure is a specific treatment which serves to remove cementum and surface dentin that is embedded with unwanted microorganisms, toxins and tartar. The root of the tooth is literally smoothed in order to promote good healing. Having clean, smooth root surfaces helps bacteria from easily colonizing in future.
Following these deep cleaning procedures, the gum pockets may be treated with antibiotics. This will soothe irritation and help the gum tissues to heal quickly.
During the next appointment, the dentist or hygienist will thoroughly examine the gums again to see how well the pockets have healed. If the gum pockets still measure more than 3mm in depth, additional and more intensive treatments may be recommended.
If you have any concerns or questions about scaling and root planing, or periodontal disease, please ask your dentist.
Bone Grafting
Periodontal disease is the leading cause of bone loss in the oral cavity, though there are others such as ill-fitting dentures and facial trauma. The bone grafting procedure is an excellent way to replace lost bone tissue and encourage natural bone growth. Bone grafting is a versatile and predictable procedure which fulfills a wide variety of functions.
A bone graft may be required to create a stable base for dental implant placement, to halt the progression of gum disease or to make the smile appear more aesthetically pleasing.
There are several types of dental bone grafts. The following are the most common:
- Autogenous bone graft - In this type of graft the bone is removed from elsewhere in the body and implanted in the mouth. Common donor sites for bone grafting include the iliac section of the pelvis, the chin and the posterior third molar areas of the jaw. If large amounts of bone need to be harvested, the hip or the shin bone (tibia) is generally used.
- Allograft - Synthetic bone (man made) can be created in the laboratory and used in the bone grafting procedure. Bone can also be obtained from a bone bank (cadaver bone).
- Xenograft - This is the implantation of bovine (cow) bone. A xenograft is perfectly safe and has been used successfully for many years. Ample bone can be obtained and no secondary donor site is necessary.
Reasons for bone grafting
There are a wide variety of reasons why bone grafting may be the best option for restoring the jaw bone.
Dental implants - Implants are the preferred replacement method for missing teeth because they restore full functionality to the mouth; however, implants need to be firmly anchored to the jawbone to be effective. If the jawbone lacks the necessary quality or quantity of bone, bone grafting can strengthen and thicken the implant site.
Sinus lift - A sinus lift entails elevating the sinus membrane and grafting bone onto the sinus floor so that implants can be securely placed.
Ridge augmentation - Ridges in the bone can occur due to trauma, injury, birth defects or severe periodontal disease. The bone graft is used to fill in the ridge and make the jawbone a uniform shape.
Nerve repositioning - If the inferior alveolar nerve requires movement to allow for the placement of implants, a bone grafting procedure may be required. The inferior alveolar nerve allows feeling and sensation in the lower chin and lip.
What does bone grafting treatment involve?
Bone grafting is a fairly simple procedure which may be performed under local anesthetic; however if large amounts of bone area need to be grafted, general anesthetic may be required.
Initially, the grafting material needs to either be harvested or prepared for insertion. A small incision is made in the gum tissue and then gently separated from the bone. The bone grafting material is then placed at the affected site.
The bone regeneration process may be aided by:
- Gum/bone tissue regeneration - A thin barrier (membrane) is placed below the gum line over the grafting material. This barrier creates enough space for healthy tissue to grow and separates the faster growing gum tissue from the slower growing fibers. This means that bone cells can migrate to the protected area and grow naturally.
- Tissue stimulating proteins - Enamel matrix proteins occur during natural tooth development. Emdogain is a matrix protein product which is usually placed on the affected site before the gum is sutured. It mediates the formation of accellular cementum on the tooth which provides a foundation to allow periodontal attachment to occur. Tissue stimulating proteins help to create lost support in areas affected by periodontal defects.
- Platelet-rich growth factors - A high platelet concentration liquid can be used to create a blood clot at the site of a wound. It has recently been discovered that PRGF also stimulates bone growth – meaning a denser graft in a shorter time period. The gum is sutured in place and a follow up appointment will need to be made within 10 days to assess progress. Bone grafting is a highly successful treatment and a good base for further periodontal restorations. If you have any questions about bone grafting, please ask your dentist.
