Your NHS guide to having a baby

Teeth and gums

Bleeding gums are caused by a build-up of plaque (bacteria) on the teeth. During pregnancy, hormonal changes in your body can cause the plaque to make your gums more inflamed (swollen) and bleed more easily.

Keeping teeth and gums healthy

  • clean your teeth and gums carefully: ask your dentist to show you a good brushing method to remove all the plaque
  • avoid having sugary drinks (such as fizzy drinks or sweet tea) and sugary foods too often: try to keep them only to meal times
  • go to the dentist for a check-up - remember that NHS dental treatment is free while you are pregnant and for one year after your baby's birth (find an NHS dentist)
  • discuss with your dentist whether any new or replacement fillings should be delayed until after your baby is born
