Pregnancy Gingivitis: Why Your Gums Bleed More
Last updated:
Hormonal changes make your gums more sensitive to plaque
During pregnancy, rising levels of progesterone and oestrogen increase blood flow to the gums and alter your body's inflammatory response to plaque bacteria. The result: gums that bleed more easily, swell, and feel tender — even if your oral hygiene has not changed.
This is called pregnancy gingivitis, and it affects up to 75% of pregnant women according to the NHS.
When does it start?
Usually during the second trimester (months 4-6) when hormone levels rise significantly. It often peaks in the third trimester and resolves within a few months of delivery.
How to manage it
- Brush thoroughly twice daily — do not avoid bleeding areas. The bleeding is caused by inflammation, and cleaning the area helps resolve it.
- Clean between teeth daily — interdental brushes are the most effective method.
- Book a dental check-up. NHS dental treatment is free during pregnancy and for 12 months after birth. Ask your midwife for a maternity exemption certificate.
- If morning sickness is an issue: Rinse with water after vomiting. Wait 30 minutes before brushing (acid softens enamel).
When to worry
See your dentist if: gums are severely swollen, you notice a lump on your gum (pregnancy epulis — benign but should be checked), or pain is affecting your eating.
