Why pregnancy challenges the teeth

The hormonal change makes the gums more sensitive — they react more strongly to deposits and are more prone to inflammation and bleeding. In addition, some experience nausea and vomiting (stomach acid attacks the enamel) as well as more frequent snacking. All of this increases the risk of gum inflammation and caries.

Pregnancy gingivitis

Red, swollen gums that bleed when brushing are common during pregnancy. The good news: with thorough oral hygiene and a professional cleaning, this can usually be managed well. More on the background in the article bleeding gums.

What helps now

  • Thorough oral hygiene including the interdental spaces — twice a day
  • After vomiting do not brush immediately (the enamel is briefly soft from the acid), instead rinse with water and wait a little
  • Have a professional cleaning — it is sensible and safe during pregnancy too
  • Pay attention to a balanced diet that is not too high in sugar
Dental visit during pregnancy

Check-ups and cleaning are sensible at any time. Larger planned treatments are best scheduled in the second trimester. Always tell us that you are pregnant — then we tailor everything accordingly.

The old saying 'every child costs a tooth' no longer has to be true — with good prevention your teeth stay healthy. You can find more about our dental hygiene on the treatment page, or arrange an appointment at Löwenplatz in Zurich.
