Pregnancy and Gum Health: Why Expecting Mothers Should Pay Attention

Pregnancy is a time of transformation — emotionally, physically, and hormonally. As your body adapts to support new life, you’re likely focusing on prenatal vitamins, OB visits, nutrition, and rest. But there’s one important area of health that’s often under-discussed during pregnancy: gum health.

At Alma Dental Care in Petaluma, CA, we’re here to support expecting patients through every stage of life, including this exciting chapter. Whether you’re in your first trimester or nearing delivery, understanding how pregnancy affects your mouth — and what you can do about it — is key to protecting both your smile and your overall well-being.

Hormones and Your Gums: What Changes During Pregnancy?

During pregnancy, hormonal changes — especially increases in progesterone and estrogen — affect nearly every part of your body, including your mouth. These hormones can make your gums more reactive to the plaque and bacteria that naturally build up on teeth. As a result, many patients experience noticeable changes in their oral health, such as:

• Swollen, red, or tender gums
• Gums that bleed when brushing or flossing
• Increased gum sensitivity or discomfort
• A condition called pregnancy gingivitis, often developing during the second trimester

While these changes are common, they’re not something you have to “just live with.” Left unmanaged, gingivitis can progress into periodontitis, a more serious gum infection that affects the bone around your teeth and increases your risk for long-term dental problems.

Why Gum Health Matters for Pregnancy Outcomes

More than just a localized infection, periodontal disease has been linked to broader health concerns — including those affecting pregnancy. Research has suggested that gum disease may contribute to a higher risk of:

• Preterm birth
• Low birth weight
• Preeclampsia or pregnancy-related hypertension

While the exact relationship between gum disease and pregnancy complications is still being studied, inflammation in the mouth is known to trigger immune responses that may influence systemic health. Taking steps to keep your gums healthy is a proactive way to support your body — and your baby — during this time.

How to Care for Your Gums While Expecting

Maintain Regular Dental Visits: Routine dental cleanings and exams are not only safe during pregnancy — they’re recommended. Let us know you’re pregnant so we can personalize your care. If possible, schedule a cleaning during your second trimester, when you’re likely to be most comfortable.

Prioritize At-Home Hygiene: Brush gently twice a day with a soft-bristled toothbrush and fluoride toothpaste. Daily flossing is just as essential — even if your gums are more sensitive than usual. If you notice bleeding, don’t stop flossing; instead, mention it to Dr. Serrano so we can monitor it closely.

Stay Hydrated and Nourished: A balanced diet supports more than your baby’s development — it also supports your teeth and gums. Nutrients like calcium, vitamin D, and vitamin C are especially important for oral health. Drinking plenty of water also helps rinse away bacteria between meals.

Manage Morning Sickness Wisely: If you’re experiencing frequent vomiting, the acid can erode tooth enamel and irritate gums. Rinse your mouth with water or a baking soda solution (1 tsp baking soda in a cup of water) afterward — but wait at least 30 minutes before brushing to avoid further enamel wear.

Be Aware of Pregnancy-Related Gum Overgrowth: Some pregnant patients may notice a small lump or swelling along the gumline, most often during the second trimester. This is known as a pyogenic granuloma — a non-cancerous growth caused by hormonal changes and increased blood flow in the gums. These growths are typically harmless and often go away after childbirth. However, if you notice any unusual lumps, swelling, or rapid changes in your gums, it’s important to let us know so we can evaluate and monitor the area.

Is Dental Treatment Safe During Pregnancy?

Yes — most dental procedures are safe and encouraged during pregnancy, particularly in the second trimester. Cleanings, exams, fillings, and even X-rays can be safely performed. If you’re in discomfort or notice signs of infection, it’s important not to delay care.

At Alma Dental Care, we’ll always coordinate closely with you — and your OB-GYN if needed — to ensure any treatment is appropriate, comfortable, and stress-free.
