Bleeding Gums During Pregnancy — Is It Normal? What to Do

June 20, 2026  ·  3 min read

If your gums have started bleeding since you became pregnant — you are not alone. Pregnancy gingivitis affects an estimated 60–70% of pregnant women and is one of the most common dental complaints during pregnancy. Here is everything you need to know.

Why do gums bleed more during pregnancy?

The hormonal changes of pregnancy — particularly rising progesterone and oestrogen levels — cause gum tissue to react more strongly to plaque bacteria. The same amount of plaque that would cause minimal irritation in a non-pregnant person can trigger a significantly more pronounced inflammatory response in a pregnant woman. The gums become more swollen, more vascular (contain more blood vessels), and bleed more easily.

This exaggerated inflammatory response typically begins around the second trimester and usually improves after delivery, though the timing varies.

Is pregnancy gingivitis dangerous?

Untreated gum disease during pregnancy has been associated in research studies with preterm birth, low birth weight, and pre-eclampsia. While the causal relationship is still being studied, the association is significant enough that all major dental and obstetric guidelines recommend that pregnant women maintain good oral health and attend dental cleanings during pregnancy.

Bleeding gums that are left untreated can progress from gingivitis (reversible) to periodontitis (which involves bone loss and is harder to reverse).

Is dental treatment safe during pregnancy?

Yes. Routine dental cleaning (scaling and polishing) is safe throughout pregnancy and is actively recommended. Local anaesthetic (lidocaine) is considered safe during pregnancy. Dental X-rays are generally avoided unless urgent, and if needed, a lead apron is used. Most elective cosmetic treatment is best deferred until after delivery.

The second trimester (weeks 14–28) is generally considered the ideal time for non-emergency dental procedures. Emergency treatment is appropriate at any stage of pregnancy.

What you can do at home

Brush gently twice daily with a soft-bristled brush. Floss daily — do not stop because it causes bleeding. The bleeding from flossing will reduce as gum health improves. Rinse with warm salt water (half a teaspoon of salt in a glass of warm water) 1–2 times daily. Avoid sugary snacks and drinks, which fuel the bacteria causing gum inflammation.

When to see a dentist during pregnancy

If you have not already visited a dentist since becoming pregnant, book a cleaning and check-up. Mention your pregnancy so the dental team can adjust any X-ray or treatment protocols accordingly. If you notice a red, swollen lump on your gums that bleeds easily — this is likely a pyogenic granuloma (‘pregnancy tumour’), a harmless vascular growth that resolves after delivery but should be assessed by a dentist.
