Dental treatment can be done at any time during pregnancy. However, the best time to perform elective dental treatment during pregnancy is in the second trimester, weeks 14 through 20.

Keep in mind that if you have a dental infection or swelling, you might need immediate treatment. The consequences of not treating an infection during pregnancy outweigh the possible risks of the medications used during dental treatment.

In addition, the U.S. Food and Drug Administration recommends that non-mercury fillings be used, when possible, in women who are pregnant or are planning to become pregnant. This is due to concern about harmful health effects related to mercury exposure. Removing or replacing existing fillings that contain mercury and are in good condition isn't recommended, however, unless medically necessary. The removal process might cause a temporary increase in exposure to mercury vapor.

If you have questions or concerns about dental care during pregnancy, talk to your health care provider.
