A radiograph may be needed for dental treatment that can’t wait until after the baby is born. Because untreated dental infections can pose a risk to the fetus, dental treatment may be necessary to maintain the health of the mother and child.
Radiation exposure resulting from dental X-rays is low. However, every precaution is taken to ensure that radiation exposure is As Low As Reasonably Achievable (the ALARA principle).
A leaded apron minimizes exposure to the abdomen and should be used when any dental radiograph is taken. Also, a leaded thyroid collar can protect the thyroid from radiation and should also be used whenever possible. The use of a leaded thyroid collar is recommended for women of childbearing age, pregnant women, and children.
Dental X-ray exams do not need to be delayed if you are trying to become pregnant or are breast-feeding.
