Bleeding Gums (Pregnancy Gingivitis)

What It Is & Why It Happens

Bleeding gums, or pregnancy gingivitis, affect up to 75% of pregnant individuals. It is characterized by red, swollen, tender gums that bleed easily during regular brushing and flossing.

The primary cause is the rise in progesterone levels. Progesterone increases blood circulation to all mucosal tissues, including the mouth. This vascular surge makes the gum tissue highly sensitive and compromises the body’s natural response to plaque (the bacteria-laden film on teeth).

Even a small amount of plaque buildup can trigger inflammation, swelling, and bleeding in pregnant gums, whereas the same amount of plaque might cause no symptoms before pregnancy. Additionally, some individuals develop small, benign swellings on their gums called pregnancy epulis or “pregnancy tumors,” which bleed easily but usually disappear after birth.

Typical Timeline

Pregnancy gingivitis typically develops during the second trimester (around Week 12) and can peak during the third trimester (up to Week 40). Gums remain vascular and sensitive until delivery, returning to their normal, non-bleeding state within a few weeks postpartum.

Safe Comfort Measures

You can protect your teeth and manage bleeding gums safely with these oral hygiene habits:

• Brush Gently: Brush your teeth at least twice a day using a soft-bristled toothbrush. Avoid brushing too hard, which can irritate sensitive gums.
• Floss Daily: Continue to floss once a day to remove plaque between teeth. Be gentle near the gum line. Do not skip flossing because of bleeding, as skipping it allows more plaque to build up, worsening the inflammation.
• Use an Alcohol-Free Mouthwash: Rinse daily with a gentle, alcohol-free antibacterial mouthwash or a warm saltwater rinse (1/2 teaspoon of salt in warm water) to soothe inflamed gums.
• Schedule a Dental Visit: Visit your dentist for a professional cleaning and examination. Professional cleanings remove tartar (hardened plaque) that you cannot brush away.
• Eat a Balanced Diet: Consume foods rich in Vitamin C (citrus fruits, strawberries, bell peppers) to strengthen blood vessels and support gum health, and limit sugary snacks that promote bacterial growth.

When to Call the Doctor or Dentist (Red Flags)

While mild gum sensitivity is expected, signs of severe periodontal infection require clinical dental management.

Contact your dentist or healthcare provider if you experience:

• Severe, localized pain or throbbing in your gums or teeth.
• Extreme swelling, gums that pull away from your teeth (receding gums), or loose teeth.
• Persistent, heavy bleeding that does not stop after brushing, or pus draining from the gums.
• A large, painful swelling on the gums (possible pregnancy epulis) that interferes with eating or speaking.
• Fever, chills, or difficulty swallowing accompanying oral pain.
