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
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.
