A new study advised that expecting mothers should take care of health of their mouth and if not they will multiply the risk of having more pregnancy problems by oral bacterias.

Researchers from Case School of Dental Medicine (CSDM), Case Western Reserve University (CWRU), U.S., established that even healthy pregnant women could be at high risk of pregnancy-related problems if they neglect their oral health and dental hygiene is most important part of overall health of the pregnant women.
Research team conducted the experiment in pregnant mice by injecting saliva from healthy people and from people having periodontal diseases that affect one or more periodontal tissues.
Researchers found that mice injected with saliva of people with dental plaque had oral bacteria which grew into their placentas.

This led the researchers to understand that several bacteria originating in the mouth travel through bloodstream and cause inflammation in the placenta, eventually impacting the overall health of the mother and unborn child. This could also lead to miscarriages and still births, as known from various other studies, stated the researchers. They contradicted the results of earlier studies that “infections are transmitted to placenta in pregnant women through vagina”
