Emergency dental treatment is generally safe during pregnancy. However, as with any medical procedure, there are potential risks and side effects that should be considered. Emergency dental treatment should only be performed when absolutely necessary, and only after consultation with your healthcare provider. 

Emergency dental treatment may include: x-rays, extractions, fillings, root canals, or other procedures. Emergency dental treatment may pose a small risk to the developing fetus, but the benefits usually outweigh the risks. 

Emergency dental treatment is typically very uncomfortable and can be quite pricey. If you have any concerns about emergency dental treatment during pregnancy, please consult with your healthcare provider or dentist first to make sure that the procedure is safe for both you and your baby.
