Preventive dental cleanings and annual exams during pregnancy are not only safe, but are recommended. The rise in hormone levels during pregnancy causes the gums to swell, bleed, and trap food causing increased irritation to your gums. Preventive dental work is essential to avoid oral infections such as gum disease, which has been linked to preterm birth.
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.
Dental work often requires antibiotics to prevent or treat infections. Antibiotics such as penicillin, amoxicillin, and clindamycin, which are labeled category B for safety in pregnancy, may be prescribed after your procedure.
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.

Dental veneers have long been used to create the ultimate smile makeover, with this treatment it is possible to transform crooked, stained, damaged and badly worn teeth into a brand new straight white smile as seen on many of the Hollywood greats.
Veneers are wafer thin lamintates or shells of tooth coloured material (which can be either porcelain, ceramic or composite bonding material) that are “cemented” to the front surface of teeth to improve their cosmetic appearance. Many dentists use the analogy that dental veneers are for your teeth what false finger nails are for your hands. In a similar manner to how false finger nails are placed or glued to your existing fingernails, veneers are bonded to the front of your existing teeth.
