Health hints : Brush teeth for a healthier baby

Researchers have warned that even healthy expecting women can be at risk for pregnancy problems caused by oral bacteria.Yiping Han, from the department of periodontics in the School of Dental Medicine, led the study that found several new bacteria originating in the mouth travel through the blood to cause an inflammatory reaction in the placenta and eventually cause a range of health issues from miscarriages to stillbirths.

Researchers have been baffled why oral bacteria have shown up in the placenta or amniotic fluid of pregnant women.

They found that after injecting the blood in the tails of pregnant mice with saliva from healthy people and dental plaque from those with periodontal disease, oral bacteria continued to grow in the placentas after it had left the mice blood 24 hours later.

This suggests that even healthy pregnant women should be concerned bacteria that normally lives in the mouth can enter the blood stream and make their way into the placenta’s immune-free environment to ignite an inflammatory reaction that can lead to premature or stillbirths.
