Oxfordshire Community Dental Service – Oral health in pregnancy

Pregnancy and oral health

Hormonal changes during pregnancy can make your gums more vulnerable to plaque, leading to inflammation and bleeding.

Bleeding gums

Some women get swollen and sore gums, which may bleed. Bleeding gums are caused by a build-up of plaque on the teeth.

It is very important to keep up with your oral health care routine.

Morning sickness

If you have morning sickness and you vomit, rinse your mouth afterwards with plain water.

This will help prevent the acid in your vomit attacking your teeth.

Do not brush your teeth straight away as they will be softened by the acid from your stomach.

Wait about an hour before doing so.

Keeping your teeth healthy

  • Brush your teeth twice a day, once before bed and at one other time.
  • Brush for 2 minutes using a family fluoride toothpaste. Spit don’t rinse.
  • Use 1350ppm-1500ppm fluoride toothpaste.
  • Use dental floss and interdental brushes (which clean in between your teeth).
  • Visit your dentist regularly, as often as recommended. Pregnant women can visit an NHS dentist for FREE.

Food and drink for healthy teeth

  • Drinks without sugar like milk or water help protect your teeth.
  • Savoury foods like vegetables, nuts and cheese are good for your teeth.
  • Reduce how often you have sugary foods/drinks. Try to keep them to mealtimes only.
