Mouth Body Connection
In July of 1998, the American Academy of Periodontology launched an effort to educate the public about new findings which support what dental professionals had long suspected: Infections in the mouth can play havoc elsewhere in the body.
Since July of 1998, evidence has continued to mount to support these links. While more research needs to be done to say definitively that people with periodontal disease are at higher risk for developing heart disease, stroke, uncontrolled diabetes, preterm births and respiratory disease, periodontists do know that periodontal disease is a bacterial infection, and all infections are cause for concern.
Periodontal bacteria can enter the blood stream and travel to major organs and begin new infections. Research is suggesting that this may:
- Contribute to the development of heart disease, the nation's leading cause of death.
- Increase the risk of stroke.
- Increase a woman's risk of having a preterm, low birth weight baby.
- Pose a serious threat to people whose health is compromised by diabetes, respiratory diseases, or osteoporosis.
Don't Ignore Your Oral Health
If you value your oral as well as your overall health, a periodontal evaluation is a good idea. Sometimes the only way to detect periodontal disease is through a periodontal evaluation. A periodontal evaluation may be especially important if you:
- Notice any symptoms of periodontal disease.
- Have heart disease, diabetes, respiratory disease or osteoporosis.
- Are thinking of becoming pregnant.
- Have a family member with periodontal disease. Research suggests that the bacteria that cause periodontal disease can pass through saliva. This means the common contact of saliva in families puts children and couples at risk for contracting the periodontal disease of another family member
- Have a sore or irritation in your mouth that does not get better within two weeks.
Researchers have suggested that a link between osteoporosis and bone loss in the jaw. Studies suggest that osteoporosis may lead to tooth loss because the density of the bone that supports the teeth may be decreased, which means the teeth no longer have a solid foundation. However, hormone replacement therapy may offer some protection.
A study published in the August 1999 Journal of Periodontology concludes that estrogen supplementation in women within five years of menopause slows the progression of periodontal disease. Researchers have suspected that estrogen deficiency and osteopenia/osteoporosis speed the progression of oral bone loss following menopause, which could lead to tooth loss. The study concluded that estrogen supplementation may lower gingival inflammation and the rate of attachment loss (destruction of the fibers and bone that support the teeth) in women with signs of osteoporosis, thus helping to protect the teeth.
For a long time we've known that risk factors such as smoking, alcohol use, and drug use contribute to mothers having babies that are born prematurely at a low birth weight.
Now evidence is mounting that suggests a new risk factor – periodontal disease. Pregnant women who have periodontal disease may be seven times more likely to have a baby that is born too early and too small.
More research is needed to confirm how periodontal disease may affect pregnancy outcomes. It appears that periodontal disease triggers increased levels of biological fluids that induce labor. Furthermore, data suggests that women whose periodontal condition worsens during pregnancy have an even higher risk of having a premature baby.
All infections are cause for concern among pregnant women because they pose a risk to the health of the baby. The Academy recommends that women considering pregnancy have a periodontal evaluation.
People with diabetes are more likely to have periodontal disease than people without diabetes, probably because diabetics are more susceptible to contracting infections. In fact, periodontal disease is often considered the sixth complication of diabetes. Those people who don't have their diabetes under control are especially at risk.
A study in the November issue of the Journal of Periodontology found that poorly controlled type 2 diabetic patients are more likely to develop periodontal disease than well-controlled diabetics are.
Research has emerged that suggests that the relationship between periodontal disease and diabetes goes both ways - periodontal disease may make it more difficult for people who have diabetes to control their blood sugar.
Severe periodontal disease can increase blood sugar, contributing to increased periods of time when the body functions with a high blood sugar. This puts diabetics at increased risk for diabetic complications. Thus, diabetics who have periodontal disease should be treated to eliminate the periodontal infection.
This recommendation is supported by a study reported in the Journal of Periodontology in 1997 involving 113 Pima Indians with both diabetes and periodontal disease. The study found that when their periodontal infections were treated, the management of their diabetes markedly improved
Bacterial respiratory infections are thought to be acquired through aspiration (inhaling) of fine droplets from the mouth and throat into the lungs. These droplets contain germs that can breed and multiply within the lungs to cause damage. Recent research suggests that bacteria found in the throat, as well as bacteria found in the mouth, can be drawn into the lower respiratory tract. This can cause infections or worsen existing lung conditions. People with respiratory diseases, such as chronic obstructive pulmonary disease, typically suffer from reduced protective systems, making it difficult to eliminate bacteria from the lungs.
Scientists have found that bacteria that grow in the oral cavity can be aspirated into the lung to cause respiratory diseases such as pneumonia, especially in people with periodontal disease. This discovery leads researchers to believe that these respiratory bacteria can travel from the oral cavity into the lungs to cause infection.
Chronic obstructive pulmonary diseases (COPD) cause persistent obstruction of the airways. The main cause of this disease is thought to be long-term smoking. Chemicals from smoke or air pollution irritate the airways to cause obstruction. Further damage to the tissue and working function of the lungs can be prevented, but already damaged tissue cannot be restored - untreated or undetected COPD can result in irreversible damage. Scientists believe that through the aspiration process, bacteria cam cause frequent bouts of infection in patients with COPD. Studies are now in progress to learn to what extent oral hygiene and periodontal disease may be associated with more frequents bouts of respiratory disease in COPD patients.
