Oral Health and Pre-Term Birth

There may be a link between oral health and pre-term birth, according to new research. A Case Western and Yale University study published in the Journal of Clinical Microbiology has revealed that a certain bacterium may contribute to up to 80% of pre-term births. Bergeyella zoohelcum, a gram-negative strain of bacteria usually associated with dog and cat bites, has been found in the oral cavities and uteri of women experiencing premature labor. It is thought that the bacteria may enter the bloodstream from the mouth, traveling to the uterus. In response to the infection, the uterus produces prostaglandins which generate contractions, leading to early labor. Pre-term birth is a major cause of birth defects, including mental retardation, blindness and hearing problems. In the United States, up to 12% of all births are classified as premature, a number that has risen in the last two decades.

While more research is needed to establish a causal link between the bacteria and early labor, preventative measures can easily be taken to reduce the risk to the mother and baby. Good oral hygiene, consisting of regular brushing and flossing, should be practiced as a matter of course by all pregnant women. Expectant mothers should also avoid sugary or starchy foods which contribute to bacteria growth. Pregnant women should also seek immediate treatment for any oral problems. By practicing preventative and pro-active measures, pregnant women can radically reduce the risk of infection and premature birth, helping to ensure a problem-free pregnancy and a healthy, happy baby.
