Bleeding gums during pregnancy, often called pregnancy gingivitis, affect the majority of pregnant women and appear as early as the first trimester. This bleeding during brushing or spontaneously is linked to the hormonal changes of pregnancy, which make the gums more reactive to dental plaque. Although it is common and usually harmless, it should not be ignored, as untreated inflamed gums can worsen.
key takeaways
- Pregnancy gingivitis affects up to 3 out of 4 pregnant women: the increase in hormones amplifies the gums' reaction to dental plaque.
- Bleeding gums during pregnancy are usually reversible with gentle but thorough oral hygiene and a professional cleaning.
- Dental check-ups are recommended during pregnancy: an examination by a dentist is even covered 100% in France.
- You should never treat bleeding gums by brushing less: on the contrary, clean better and more gently.
Why do gums bleed more during pregnancy?
During pregnancy, increased oestrogen and progesterone levels increase blood flow to the gums and change how they respond to plaque bacteria. Gums that were previously healthy can then become red, swollen and start bleeding at the slightest contact, even if oral hygiene has not changed.
This phenomenon often begins as early as the second month, intensifies during the second trimester, then subsides spontaneously after childbirth when hormone levels return to their usual levels. As with any bleeding gums, the underlying cause remains poorly removed plaque: hormones simply amplify existing inflammation.
In some cases, a small, red and painless growth appears on the gum between two teeth: this is called a pregnancy tumour. This benign growth bleeds easily but usually disappears on its own after childbirth.

Is it dangerous for the baby?
Bleeding gums during pregnancy are not dangerous in themselves, but significant and lasting inflammation deserves attention. Several studies have associated advanced forms of gum disease with a slightly higher risk of premature birth or low birth weight. This link is not inevitable, but it is a reason not to leave inflammation untreated.
Taking care of your gums is therefore part of pregnancy care, just like everything else. If the inflammation worsens, the bleeding becomes heavy or the gums recede, consult a dentist without delay.
How can you soothe bleeding gums during pregnancy?
The good news is that pregnancy gingivitis responds very well to suitable oral hygiene. The aim is to remove plaque gently, without irritating gums that are already weakened.
- Brush twice a day, gently. A soft-bristled toothbrush and a non-aggressive technique are all you need: it is consistency, not force, that removes plaque.
- Clean between your teeth every day. Dental floss or interdental brushes reach the areas where gingivitis begins, between the teeth and beneath the gumline.
- Rinse if nausea makes brushing difficult. After vomiting, rinse with water (with a little baking soda if needed) and wait before brushing to protect the enamel.
- Make an appointment for a professional cleaning. Professional cleaning is safe during pregnancy and remains the most effective way to stop inflammation.
For gentle yet thorough cleaning, a sonic toothbrush helps remove plaque without having to press. The Y-Brush sonic toothbrush, shaped like a Y, brushes the entire jaw in 10 seconds and is 2× more efficient than traditional electric toothbrushes, according to tests carried out by Y-Brush.
What should you avoid?
When gums bleed, stopping brushing the area is the worst reaction: plaque builds up, inflammation worsens and the bleeding increases. Likewise, some powerful antiseptic mouthwashes are not suitable for prolonged use during pregnancy: always ask for advice before using them.
Finally, do not postpone treatment out of concern for the baby. Routine dental care, including professional cleaning, is possible during pregnancy, and the second trimester is often the most comfortable time for an appointment. If in doubt, your dentist will adapt the treatment to your situation.
