Dental Care and Oral Health During Pregnancy

The body goes through many changes during pregnancy. Hormonal changes are often accompanied by an elevated tendency for gingivitis and a worsening of existing dental problems. Gingivitis will manifest as bleeding from the gums during brushing or use of dental floss, accompanied by sensitive gums.

iIt is important to note that the bacterial composition found in the mother’s mouth will determine the bacterial composition that the baby will develop after birth, meaning that bacteria that can cause caries or gum disease will be transmitted to the baby and will determine the health of their teeth for the rest of their life.

Amalgam and mercury in pregnant women

Studies have shown a correlation between mercury levels in the umbilical cord and the number of amalgam fillings in a mother’s mouth, and several studies have shown a link between mercury transfer to the fetus and autism, as well as other developmental problems in newborn babies.

If immediate action is required for a tooth with an amalgam filling (due to a broken tooth, pain, etc.) – it is imperative to perform such treatment in a clinic that practices safe amalgam removal while using special equipment, in order to prevent harmful fetal exposure to mercury. We also recommend postponing elective treatments until after birth and breastfeeding.

What is recommended during pregnancy?

In order to prevent gingivitis, it is recommended maintain regular visits to the dental hygienist for teeth cleaning and plaque removal (every three months – if necessary), and to keep a meticulous brushing and flossing routine. It is also recommended to consult a dentist during periodic check-ups and integrate the use of various hygiene products (toothpaste, mouthwash) that can help during this time.

In addition, in order to minimize the transfer of bacteria responsible for caries to the baby after birth, the use of gum and candies containing a sugar substitute called XYLITOL is recommended. Xylitol is safe to use during pregnancy and breastfeeding, and significantly inhibits the development of harmful bacteria in the mother’s mouth, thereby eliminating the risk of transfer of these bacteria to the baby, hence supporting the development of healthier composition of bacteria in the baby’s mouth. For this reason, it is recommended for use especially during the third trimester and during breastfeeding.

X-rays during pregnancy

Routine X-rays are not performed during pregnancy, however when emergency treatment is necessary and an X-ray is required for diagnosis, the minimum number of X-rays required for the treatment is performed, and a radiation-blocking apron is used to reduce X-ray exposure for you and your fetus.
