Pregnant? See Your Dentist

May 9, 2000 -- Most pregnant women know that to keep a growing baby healthy,
they must lay off alcohol and cigarettes and eat a balanced diet. Now,
researchers say, they should add carefully caring for their teeth and gums to
that list. A new study shows that women with serious cases of periodontal
disease are far more likely to give birth early.
Although the results are preliminary, researchers are already recommending
that pregnant women have their dentists screen for the condition, and that
women who suffer from periodontal disease have their dentists carefully clean
and disinfect the space between their teeth and gums.
Babies born prematurely face a dramatically increased risk of cerebral
palsy, visual problems, and other disorders and account for more than half of
all health care costs for newborns. And one in every four women who give birth
prematurely has no known risk factors, researcher Marjorie Jeffcoat, DMD, says.

Past studies have found that pregnant women who suffer from periodontal
disease are up to seven times as likely to give birth to premature,
Now, by keeping tabs on more than 700 otherwise healthy pregnant women who
did not drink, smoke, or have genital or urinary tract infections -- all risk
factors for preterm births -- Jeffcoat and her colleagues have found that the
risk of premature birth is highest in women with the most severe form of the
disorder. This type, called generalized periodontal disease, affects more than
30% of the mouth. Women who have this type of disease have a risk of premature
birth that is eight times that of women who don't have periodontal disease.
The work was presented Sunday at the American Academy of Periodontology's
Specialty Conference on Periodontal Medicine in Washington.
Periodontal disease begins with plaque, which coats the teeth with a
bacterial film. About 22% of pregnant women have periodontal disease, which
occurs when a bacterial infection between the teeth and gums loosens and
separates the gum from its moorings. That creates a pocket for more bacteria to
