Oral Health and Heart Disease continued...

Recent analysis suggests that common oral problems could increase the risk of cardiac problems. Indra Mustapha, DDS, a periodontist who teaches at Howard University in Washington, D.C., and colleagues analyzed the results of other research studies and found that periodontal disease with signs of bacterial exposure was associated with greater risk of heart disease.

The American Heart Association states, "At this time, promoting dental treatment expressly to prevent atherosclerotic cardiovascular disease and/or acute cardiovascular events is not recommended."

Oral Health and Premature Birth

"Ob-gyns always knew that preterm and low-birth- weight births could be triggered by infections in the body," says Karabin. "They looked for urinary tract infections and throat infections, but never really thought about the mouth until a periodontic researcher looked into it."

Karabin says that severe periodontal disease in the mother may lead to an increase in the risk of premature birth. Remember those cytokines? Turns out they also increase the level of the hormone prostaglandin, which triggers labor, says Karabin. Fortunately, studies show that early treatment of gum disease and improved oral hygiene in women can reduce their risk of premature birth.

Other conditions that indicate a link between dental health and overall health include:

  • Osteoporosis. Osteoporosis and tooth loss often go hand in hand because the same decrease in mineral density that boosts the risk of hip and other fractures affects the jawbone and teeth. Measures taken to prevent or treat osteoporosis in postmenopausal women are likely to also help prevent severe gum disease, Genco says.
  • Rheumatoid arthritis. A study released in June 2008 found that patients with rheumatoid arthritis (RA) were nearly eight times more likely to have periodontal disease. RA, like periodontal disease, is an inflammatory disorder, which may help explain the link, Karabin says.
  • Alzheimer's disease. A 2005 study of identical twins showed that in twin pairs where one had dementia and the other didn't, the ones with dementia were four times more likely to have gum disease by midlife. The study doesn't say that good oral heath prevents Alzheimer's, but that inflammation early in life can have severe consequences later.
