Pregnancy gingivitis - why teeth bleed during pregnancy?

April 09, 2025

  

Pregnancy is a transformative time, both emotionally and physically—but did you know it can also affect your oral health? Pregnancy gingivitis, a common condition during pregnancy, can lead to swollen gums and bleeding while brushing or flossing. This issue typically arises in the second trimester and affects nearly 60-70% of pregnant women. Understanding why teeth bleed during pregnancy is essential for maintaining both oral hygiene and overall well-being during these critical months.

What Is Pregnancy Gingivitis?

Pregnancy gingivitis is a mild form of gum disease that occurs due to hormonal changes, particularly increased levels of progesterone and estrogen. These hormones heighten the body’s response to plaque—a sticky film of bacteria on teeth—making gums more sensitive and prone to inflammation.
If left untreated, pregnancy gingivitis can progress into more severe forms of gum disease, such as periodontitis, which has been linked to adverse pregnancy outcomes like preterm birth and low birth weight.

Why Do Teeth Bleed During Pregnancy?

1. Hormonal Changes

During pregnancy, hormonal fluctuations increase blood flow to gum tissues, making them more sensitive and reactive to plaque. As a result, gums become swollen, tender, and bleed more easily—especially during brushing or flossing.

2. Increased Plaque Buildup

Many women experience changes in diet and oral hygiene habits during pregnancy, sometimes neglecting consistent brushing and flossing due to nausea or fatigue. This can lead to plaque accumulation, triggering pregnancy gingivitis and causing gums to bleed.

3. Weakened Immune Response

Pregnancy naturally suppresses the immune system to support the growing fetus. However, this also makes it harder for the body to combat bacterial infections in the mouth, leading to gum inflammation and bleeding.

Signs and Symptoms of Pregnancy Gingivitis

Be aware of these common symptoms:
• Red, swollen, or tender gums
• Bleeding during brushing or flossing
• Persistent bad breath
• Gum sensitivity or discomfort
• Receding gum line in advanced cases
If you notice any of these symptoms, consult your dentist for personalized care and treatment.

How to Prevent Bleeding Gums During Pregnancy

1. Maintain Excellent Oral Hygiene

Brush twice a day with fluoride toothpaste and floss daily to remove plaque. Use a soft-bristled toothbrush to avoid irritating sensitive gums.

2. Schedule Regular Dental Checkups

Dental visits during pregnancy are safe and highly recommended. Inform your dentist about your pregnancy, so they can tailor your treatment appropriately and monitor for signs of pregnancy gingivitis.

3. Eat a Balanced, Nutritious Diet

Consuming foods rich in vitamin C, calcium, and folate can strengthen your gums and reduce inflammation. Avoid excessive sugary snacks that contribute to plaque buildup.

4. Use Antimicrobial Mouth Rinse

Ask your dentist to recommend a pregnancy-safe antimicrobial or saltwater rinse to help reduce bacteria and soothe inflamed gums.

When to Seek Professional Help

If gum bleeding is severe, persistent, or accompanied by pain or pus, don’t delay seeing a dentist. Early intervention can prevent complications for both you and your baby. In rare cases, untreated gingivitis can lead to periodontal disease, which poses risks during pregnancy.

Conclusion

Pregnancy gingivitis is a common yet manageable condition. If your teeth bleed during pregnancy, it’s likely due to hormonal changes that increase your gums’ sensitivity to plaque. By maintaining strong oral hygiene habits, scheduling regular dental visits, and eating a nutrient-rich diet, you can keep your gums healthy and reduce discomfort. Taking care of your oral health is an essential part of ensuring a healthy pregnancy—for both you and your baby.
