The oral microbiome and pregnancy: What dentists need to know

The oral cavity is home to the second most complex microbial population in the human body, with over 700 different bacterial species. Recent advancements in next-generation sequencing technology have shed light on the intricate dynamics of the oral microbiome, revealing its crucial role in both health and disease.

The oral microbiome during pregnancy

The composition of the oral microbiome changes significantly throughout different life stages, including pregnancy. Pregnant women, particularly in the first trimester, exhibit higher total viable microbial counts compared to non-pregnant women. Maintaining a balanced oral microbiome is essential for a healthy pregnancy, as disruptions in its composition can lead to complications.

Impact of pregnancy on oral health

Physiological changes and hormonal fluctuations during pregnancy increase the risk of oral diseases such as gingivitis and periodontitis. These conditions are not only uncomfortable but can also have broader implications for pregnancy outcomes.

Oral microbiome and pregnancy complications

Emerging evidence highlights a strong link between the oral microbiome’s composition and adverse pregnancy outcomes, including preterm birth, preeclampsia and low birth weight. Understanding these connections is vital for dentists, as they play a key role in monitoring and managing oral health during pregnancy.

Blog's point of view

As dental professionals, staying informed about the dynamics of the oral microbiome during pregnancy and its potential impact on pregnancy outcomes is crucial. By doing so, dentists can better support their pregnant patients, ensuring both oral and overall health are maintained throughout this critical period.
