Finding out you’re pregnant comes with a long list of “can I?” and “should I?” questions. From sushi to skincare, the caution is real. But what happens if you take a fall, have a toothache, or get a chest cold and your doctor suggests an X-ray?
The short answer is: Yes, you can have an X-ray while pregnant, but it depends on the type of X-ray and the urgency of the medical situation.
Here is a breakdown of the safety, the risks, and how to handle medical imaging while expecting.
Why the Concern About X-Rays?
The hesitation around X-rays stems from the use of ionizing radiation. In very high doses, radiation can potentially interfere with a baby’s rapidly dividing cells. However, the key word here is “high.”
Most diagnostic X-rays—like those for a broken arm or a dental cavity—use extremely low levels of radiation. In fact, the amount of radiation a fetus is exposed to during a standard X-ray is often less than the natural background radiation you’d receive just by living on Earth for a few months.
When Is it Safe?
Medical professionals generally follow the ALARA principle (As Low As Reasonably Achievable). If an X-ray is necessary for your health, the benefits usually far outweigh the tiny theoretical risk to the pregnancy.
1. Dental X-Rays
Dental X-rays are considered very safe. The radiation is concentrated strictly on the mouth area, and the dose is minimal. Since oral infections can actually pose a risk to your pregnancy, getting that tooth checked is often the safer choice.
2. X-Rays of the Extremities
If you suspect a broken ankle or wrist, an X-ray is perfectly fine. Because the beam is aimed far away from your abdomen, the “scatter” radiation reaching the baby is virtually nonexistent.
3. Chest X-Rays
While closer to the womb than a dental checkup, chest X-rays are still considered low-risk. With proper shielding, the exposure to the pelvic region is negligible.
When to Be More Cautious
X-rays that involve the abdomen, pelvis, or lower back require a more thorough conversation with your doctor. Because the primary beam is aimed directly near the uterus, healthcare providers will usually consider alternative imaging first, such as an Ultrasound or an MRI, which do not use ionizing radiation.
How to Protect Yourself and Your Baby
If you do need an X-ray, there are standard protocols in place to ensure maximum safety:
- Always Inform the Technician: Even if you only think you might be pregnant, tell the radiologist or dentist immediately.
- Use Lead Shielding: You should be provided with a leaded apron or “lap shield.” This heavy garment blocks the X-ray beams from reaching your reproductive organs and the developing fetus.
- The “Double Shielding” Method: In some cases, technicians may provide extra lead wrapping around the abdomen for added peace of mind.
- Question the Necessity: Ask your doctor if the X-ray can wait until after the first trimester (when the baby’s organs are forming) or until after birth.
The Bottom Line
One single diagnostic X-ray is extremely unlikely to cause harm to a developing baby. Miscarriages or birth defects from radiation are generally only associated with high-dose radiation therapy (like cancer treatments), not a standard 2-second click at the doctor’s office.
Your health matters. A mother with an undiagnosed pneumonia or a severe infection is often at greater risk than a mother who has a quick, shielded X-ray.
