What causes bleeding gums in pregnancy
Pregnancy hormones can make gum tissue more prone to inflammation, so plaque may cause bleeding during brushing or flossing.
The short answer
Pregnancy hormones can make gum tissue more prone to inflammation, so plaque may cause bleeding during brushing or flossing. This is commonly called pregnancy gingivitis, but bleeding can also reflect gum disease that needs treatment.

What is the direct answer?
What does this question mean?
The gums are the soft tissue around the teeth, and plaque is the sticky bacterial film that collects along the gumline. Hormonal changes can increase the tissue response to plaque, causing redness, swelling, tenderness, and bleeding.
What can you do next?
Brush twice daily with a soft-bristled brush and fluoride toothpaste, cleaning gently where each tooth meets the gum. Clean between the teeth daily with floss or an interdental brush, and arrange a dental cleaning if plaque or tartar is difficult to remove.
When should you seek dental care?
Arrange an examination if bleeding persists, the gums are very swollen, or you notice bad breath, pus, loose teeth, or pain. Facial swelling, fever, difficulty swallowing, or difficulty breathing needs urgent medical and dental assessment.
What should you ask the dentist?
Ask whether the bleeding is pregnancy gingivitis or established periodontal disease, and whether tartar removal is needed. Ask which cleaning products and any recommended treatment fit your pregnancy and current medicines.
