In fact, it's especially important to have a dental checkup, dental cleaning, and any necessary treatment during pregnancy. Delaying necessary treatment for oral health problems during pregnancy could result in significant risk to you and your baby.
Dental work while pregnant, 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 this dental work while pregnant and avoid exposing the developing baby to any risks, even if they are minimal.
