Are X-Rays safe during pregnancy?

What does the evidence say about X-Rays during pregnancy?

1. A routine dental X-ray delivers a radiation dose thousands of times smaller than the amount ever linked to a higher chance of birth defects. 1
2. X-rays of your teeth, head, chest, arms, or legs don't aim radiation at your belly, so they carry no meaningful risk to your baby. 2
3. The radiation dose linked to any pregnancy risk is far above what even several diagnostic X-rays add up to. 3
4. Doctors only start watching for fetal radiation risk at exposure levels many times higher than routine medical imaging ever reaches. 4
5. Worry about X-rays in pregnancy is common, but understanding the real, very low dose helps patients and doctors make calmer, more informed choices about needed imaging. 5

Is X-Rays safe in each trimester?

• First trimester. The first trimester is when your baby's organs are forming, so this is when people worry most about X-rays. A needed X-ray, including dental work, still uses a dose far below any level linked to a problem. Ask for an apron shield over your belly if the exam is anywhere near your torso.
• Second trimester. The riskiest window for organ formation has passed by the second trimester. Dental checkups, chest X-rays, and other diagnostic imaging are still considered safe, and shielding is easy to arrange for anything near your abdomen.
• Third trimester. Late-pregnancy X-rays, like a dental visit or a chest X-ray for a cough, remain safe at standard doses. If an exam is close to your belly, your care team can time it and shield you as needed rather than skip imaging you actually need.
