Pregnancy is a period of significant physical changes, which can profoundly impact a woman’s oral health. One common issue experienced by pregnant women is pregnancy gingivitis, an inflammation of the gums caused by hormonal changes.

While gingivitis can seem like a minor inconvenience, it can have severe consequences if left untreated, not only for the mother’s oral health but also for the pregnancy and the baby’s health.

1) Understanding Pregnancy Gingivitis

Pregnancy gingivitis is an inflammation of the gums caused by increased levels of hormones, particularly progesterone and estrogen, during pregnancy.

These hormonal fluctuations can enhance the body’s response to dental plaque, the sticky film of bacteria that forms on the teeth.

The gums become more sensitive, making them more susceptible to inflammation, swelling, and bleeding.

Common symptoms of pregnancy gingivitis include:

Red, swollen gums
Gums that bleed easily, especially when brushing or flossing
Tender or painful gums
Bad breath (halitosis)

Pregnancy gingivitis typically begins to appear during the second trimester of pregnancy and may persist through the entire term if not treated.

Studies suggest that between 60% to 75% of pregnant women experience some form of gingivitis during pregnancy.

2) Causes of Pregnancy Gingivitis

The primary cause of pregnancy gingivitis is an increased sensitivity of the gums due to elevated hormone levels, particularly progesterone.

However, several other factors can contribute to the development and severity of the condition:

Hormonal Changes

Pregnancy hormones can change the way the body responds to plaque bacteria.

The rise in progesterone can cause the gums to become inflamed more efficiently, leading to exaggerated reactions to bacteria buildup in the teeth.

Increased Blood Flow

During pregnancy, blood flow to the gums increases significantly, making them more prone to swelling and bleeding. This increased blood circulation to the gums and the heightened sensitivity caused by hormonal changes can exacerbate inflammation.

Dietary Changes

Pregnant women may consume more carbohydrates or sugary foods, which can fuel plaque formation and increase the risk of gingivitis.

Cravings for sweet or starchy foods, common culprits for plaque buildup, can also contribute to this.

Neglect of Oral Hygiene

Morning sickness, nausea, or fatigue during pregnancy can sometimes lead women to neglect proper oral care routines.

Accumulate plaque on the teeth and gums, increasing the risk of gingivitis.

3) Effects of Pregnancy Gingivitis on Pregnancy

While pregnancy gingivitis primarily affects the mother’s oral health, it has been linked to several pregnancy complications. Here’s how it can impact pregnancy:

Risk of Preterm Birth

Research has shown a connection between periodontal disease, which begins as gingivitis, and an increased risk of preterm birth (birth before 37 weeks of gestation).

In a study published in the Journal of Periodontology, women with untreated gum disease were found to be at a higher risk of preterm labour.

The exact mechanism behind this link is still being studied.

Still, it is believed that the bacteria from inflamed gums can enter the bloodstream and reach the placenta, triggering an inflammatory response that may induce early labour.

Low Birth Weight

Pregnant women with severe or untreated gingivitis are also more likely to give birth to babies with low birth weight (less than 5 pounds, 8 ounces).

This can occur when inflammation and infection from gum disease spread through the bloodstream, interfering with fetal growth and development.

Low birth weight babies are at a higher risk of health problems, including respiratory issues, delayed development, and a weakened immune system.

Preeclampsia

Preeclampsia is a potentially dangerous pregnancy complication characterized by high blood pressure and damage to other organs, such as the kidneys and liver.

Some studies have found a correlation between gum disease and an increased risk of preeclampsia, though more research is needed to confirm this connection.

It is hypothesized that the inflammation caused by gum disease contributes to vascular dysfunction, which may play a role in preeclampsia.

Increased Risk of Gestational Diabetes

Pregnancy gingivitis and other forms of gum disease have been linked to an elevated risk of gestational diabetes, a condition where the body has difficulty processing sugar during pregnancy.

Inflammation from gum disease may affect how the body uses insulin, leading to higher blood sugar levels.

Gestational diabetes can cause complications for both the mother and baby, including a higher risk of cesarean delivery and the baby developing diabetes later in life.

4) How Pregnancy Gingivitis Affects Oral Health

Untreated gingivitis can progress to periodontitis, a more severe form of gum disease that affects the bones supporting the teeth.

Periodontitis can cause permanent damage to the gums and teeth, including receding gums, loose teeth, and even tooth loss.

Additionally, oral infections from gum disease can spread beyond the mouth, affecting overall health.

The systemic inflammation caused by the bacteria involved in periodontal disease has been linked to other conditions, such as cardiovascular disease and diabetes.

5) Preventing and Treating Pregnancy Gingivitis

The good news is that pregnancy gingivitis can be managed effectively with proper oral hygiene and professional care. Here are some steps to prevent and treat pregnancy gingivitis:

Maintain Excellent Oral Hygiene

Brushing twice daily with fluoride toothpaste and flossing daily are essential for preventing plaque buildup.

Pregnant women should be extra vigilant about oral hygiene, especially since hormonal changes make their gums more susceptible to inflammation.

Visit the Dentist Regularly

Regular dental checkups and cleanings are crucial during pregnancy.

Dentists can detect early signs of gingivitis and provide treatments to prevent it from progressing.

Most routine dental procedures are safe during pregnancy, particularly during the second trimester.

Pregnant women should inform their dentist of their pregnancy so that appropriate precautions can be taken.

Use Antibacterial Mouthwash

An antibacterial mouthwash can help reduce the bacteria that cause plaque and gum inflammation.

However, pregnant women should consult their dentist before using any mouthwash to ensure it is safe during pregnancy.

Eat a Balanced Diet

A diet rich in vitamins and minerals, particularly calcium and vitamin C, can help maintain healthy teeth and gums.

Reducing sugar intake and eating crunchy vegetables like carrots and celery can also help clean teeth and stimulate saliva production, essential for neutralizing acids in the mouth.

Manage Morning Sickness

If morning sickness makes brushing difficult, rinsing the mouth with water or a diluted mouthwash after vomiting can help neutralize acids that can erode tooth enamel.

Waiting 30 minutes before brushing after vomiting is recommended to avoid damaging weakened enamel.

6) Postpartum Oral Health

The risk of gingivitis doesn’t end with pregnancy.

After delivery, hormonal fluctuations can continue to affect the gums.

New mothers should continue their oral care routine to prevent gum disease from progressing.

It’s also essential to establish good oral hygiene habits to avoid transmitting harmful bacteria to their newborns.

Prioritising Oral Health for a Healthy Pregnancy & Baby

Pregnancy gingivitis is a common condition that affects many expectant mothers due to hormonal changes. While it may seem like a minor issue, untreated gingivitis can lead to more severe health problems, including periodontitis and adverse pregnancy outcomes like preterm birth, low birth weight, preeclampsia, and gestational diabetes. Fortunately, with proper care, pregnancy gingivitis can be prevented and treated.

Regular dental checkups, good oral hygiene, and a balanced diet are crucial steps in preventing gum disease during pregnancy.

If you are pregnant or planning to become pregnant, it’s essential to prioritize your oral health for your and your baby’s well-being.
