If you have a tooth that is severely decayed and is causing you pain, you may need to have it extracted. If it is a back tooth that is not highly visible, you can probably wait until after you have your baby to have it replaced. However, if it is a front tooth, you may want to have it replaced with an implant immediately. As long as you are in your second trimester or beyond, it would be safe for you to have a dental implant placed under local anesthesia.
