Gum Disease and Pregnancy

Pregnancy has a fundamental impact on the general health of a woman and oral health can also be affected during pregnancy. 


"Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity."

World Health Organisation

A woman's oral health can be affected during pregnancy for a number of reasons including chronic morning sickness and increased gingival blood supply; a tendency towards gingival swelling and periodontitis.

At the same time, a suppressed immune system, lowered blood pressure and tiredness from discomfort during sleep can result in neglected oral hygiene regime, which raises the risk of periodontal disease.

The European Federation of Periodontology

The European Federation of Periodontology states in its manifesto that evidence has shown that certain oral bacteria can enter the bloodstream and cause inflammatory and immune responses that affecting the foetoplacental unit.

Results from clinical trials have shown that certain populations of pregnant women may benefit from periodontal therapy, such as scaling and root planning carried out during the second trimester. 

Clinical studies have associated low birth weight, pre-term birth and pre-eclampsia with maternal periodontal disease in the mother. However, the strength of these connection varies between studies, and some show no association, likely due to differences in study designs study populations and different methods used for assessing and classifying periodontal disease.
