The dental radiographs have a certain effect on pregnancy because they are also known as X-rays, and X-rays can be harmful to the human body. Although the radiation dose is very small and will not cause great harm to the human body, for safety reasons, if a patient who has had dental x-rays wants to get pregnant, it is clinically recommended to wait 1-3 months after the x-rays before getting pregnant, or to follow the doctor’s instructions during the x-rays and wear radiation-protective lead clothing and take radiation protection measures, which can also greatly reduce or avoid X-ray radiation.
