Dental work such as cavity fillings and crowns should be treated to reduce the chance of infection. If dental work is done during pregnancy, the second trimester is ideal. Once you reach the third trimester, it may be very difficult to lie on your back for an extended period of time.

The safest course of action is to postpone all unnecessary dental work until after the birth. However, sometimes emergency dental work such as a root canal or tooth extraction is necessary.

Elective treatments, such as teeth whitening and other cosmetic procedures, should be postponed until after the birth. It is best to avoid exposing the developing baby to any risks, even if they are minimal.

Currently, there are conflicting studies about possible adverse effects on the developing baby from medications used during dental work. Lidocaine is the most commonly used drug for dental work. Lidocaine (Category B) does cross the placenta after administration.

If dental work is needed, the amount of anesthesia administered should be as little as possible, but still enough to make you comfortable. If you are experiencing pain, request additional numbing. When you are comfortable, the amount of stress on you and the baby is reduced. Also, the more comfortable you are, the easier it is for the anesthesia to work.

Routine x-rays, usually taken during annual exams, can usually be postponed until after the birth. X-rays are necessary to perform many dental procedures, especially emergencies. According to the American College of Radiology, no single diagnostic x-ray has a radiation dose significant enough to cause adverse effects in a developing embryo or fetus.

Fetal organ development occurs during the first trimester; it is best to avoid all potential risks at this time if possible. If non-emergency dental work is needed during the third trimester, it is usually postponed until after the birth. This is to avoid the risk of premature labor and prolonged time lying on your back.
