The connection between gum disease and pregnancy complications


Pregnancy is an incredible journey marked by numerous physical and hormonal changes. It is a time when a woman’s body goes through remarkable transformations to support the growth and development of a new life. During pregnancy, it is not just the baby’s health that needs careful attention, but also the mother’s overall well-being. Emerging research has highlighted a significant connection between gum disease and pregnancy complications. Gum disease, also known as periodontal disease, is a bacterial infection that affects the gum tissues and supporting structures of the teeth. Understanding the link between gum disease and pregnancy complications is crucial for expectant mothers and healthcare providers to promote both oral health and a healthy pregnancy. In this comprehensive blog post, we will explore the connection between gum disease and pregnancy complications, understand the mechanisms behind this association, examine the scientific evidence supporting it, and discuss the importance of oral health care during pregnancy.

Understanding Gum Disease:

Gum disease is a common oral health condition that starts with the accumulation of plaque on the teeth. Plaque is a sticky film of bacteria that forms on the teeth and gumline, and if not effectively removed through proper oral hygiene practices, it can lead to gum inflammation, also known as gingivitis. Gingivitis is characterized by red, swollen gums that may bleed during brushing or flossing. If left untreated, gingivitis can progress to periodontitis, a more severe form of gum disease. In periodontitis, the infection spreads deeper into the gum tissues and can cause the gums to recede from the teeth, forming pockets where more bacteria thrive. Over time, periodontitis can lead to the loss of bone and supporting tissues around the teeth, resulting in tooth mobility and potential tooth loss.

The Link Between Gum Disease and Pregnancy Complications:

Research has shown a strong association between gum disease and pregnancy complications. Hormonal changes during pregnancy can alter the body’s response to oral bacteria, making expectant mothers more susceptible to gum disease. Additionally, the inflammation caused by gum disease can impact pregnancy outcomes, leading to potential complications for both the mother and the baby. The primary mechanisms underlying the connection between gum disease and pregnancy complications are inflammation and the release of inflammatory molecules into the bloodstream.

Systemic Inflammation: 

Gum disease triggers a chronic inflammatory response in the body. This inflammation can spread to other organs, including the placenta, affecting fetal development and increasing the risk of pregnancy complications.

Elevated Proinflammatory Cytokines: 

Inflammatory molecules called cytokines are released in response to the infection in the gums. These cytokines can enter the bloodstream and affect the placenta, potentially leading to adverse pregnancy outcomes.

Increased Risk of Preterm Birth: 

Studies have shown that pregnant women with gum disease have an increased risk of preterm birth. Preterm birth, defined as birth before 37 weeks of gestation, can lead to various health issues for the baby, including respiratory and developmental problems.

Low Birth Weight: 

Gum disease has also been associated with a higher risk of delivering a baby with a low birth weight. Low birth weight is defined as a birth weight of less than 2,500 grams (5.5 pounds) and can be linked to long-term health challenges for the baby.

Scientific Evidence Supporting the Connection:

Numerous studies have provided compelling evidence of the association between gum disease and pregnancy complications:

A study published in the Journal of Obstetrics and Gynaecology in 2002 found that pregnant women with severe gum disease were more likely to deliver preterm and have babies with low birth weights compared to women with healthy gums.

Research published in the Journal of Periodontology in 2006 demonstrated a link between gum disease and an increased risk of preterm birth and low birth weight.

A meta-analysis published in the Journal of Maternal-Fetal & Neonatal Medicine in 2018 analyzed multiple studies and found that pregnant women with gum disease had a higher risk of adverse pregnancy outcomes, including preterm birth and low birth weight.

Importance of Oral Health Care During Pregnancy:

Maintaining good oral health during pregnancy is essential for both the mother’s well-being and the baby’s development. Here are some important oral health care tips for expectant mothers:

Regular Dental Check-ups: 

Schedule regular dental check-ups during pregnancy to monitor oral health and detect any signs of gum disease or other dental issues.

Inform Your Dentist: 

Inform your dentist that you are pregnant so they can tailor treatments and procedures accordingly.

Brush and Floss Regularly: 

Practice good oral hygiene by brushing your teeth at least twice a day and flossing daily to remove plaque and prevent gum disease.

Rinse with Mouthwash: 

Using an antimicrobial mouthwash can help reduce bacteria in the mouth and support oral health.

Address Dental Issues Promptly: 

If you experience any dental problems or have concerns about your oral health, seek dental care promptly to prevent potential complications.

Follow a Balanced Diet: 

A nutritious diet that includes essential vitamins and minerals supports both oral health and the development of the baby. Limit sugary snacks and opt for a well-balanced diet rich in fruits, vegetables, lean proteins, and whole grains.

Stay Hydrated: 

Drink plenty of water throughout the day to maintain oral health and overall well-being.


The connection between gum disease and pregnancy complications highlights the significance of maintaining good oral health during pregnancy. Hormonal changes and increased susceptibility to gum disease during pregnancy can lead to inflammation and potentially affect pregnancy outcomes. By understanding the link between gum disease and pregnancy complications and following good oral hygiene practices, expectant mothers can reduce the risk of gum disease and promote a healthy pregnancy. Regular dental check-ups, proper oral care, and seeking prompt dental care for any issues are essential steps in safeguarding oral and overall health during pregnancy. Remember, taking care of your oral health during pregnancy is an integral part of ensuring a healthy journey for both you and your baby.
