Dental X-rays are considered safe during pregnancy when your dentist determines they're clinically necessary, according to guidance from the American Dental Association and the American College of Obstetricians and Gynecologists. They use very low radiation doses and protective measures keep exposure minimal, so don't postpone urgent dental care out of fear of the X-ray itself.
TL;DR:
- Dental X-rays during pregnancy are safe when clinically necessary because they involve very low radiation doses well below levels linked to fetal harm.
- Proper shielding and digital imaging technologies further minimize radiation exposure, making delays for non-urgent imaging unnecessary.
- Dentists follow strict criteria, ordering X-rays only when they will influence treatment, especially in cases of pain, trauma, or infection.
- Timing of the pregnancy trimester does not impact the safety of necessary dental X-rays, but elective imaging can be postponed until after delivery.
- Most patients who received dental X-rays before realizing they were pregnant face no increased risk, as doses are far below harmful thresholds.

Radiation Dose and What the Evidence Actually Shows
A single dental X-ray delivers a tiny fraction of the radiation a person absorbs from the environment each year. According to MotherToBaby's fact sheet on X-rays, typical background radiation exposure runs around 3 mSv annually, and diagnostic dental imaging falls far below the levels linked to pregnancy complications.
Diagnostic X-ray exposure during pregnancy is not expected to raise the risk of miscarriage or birth defects, per MotherToBaby, because the fetal dose from routine imaging like dental X-rays sits well under any threshold connected to those outcomes.
A few points worth understanding about how this evidence holds up:
- Diagnostic X-rays don't linger in the body or transfer into breastmilk, so there's no residual exposure after the image is taken.
- Reviews of dental radiography in pregnancy have found that properly performed imaging is unlikely to approach the radiation levels associated with fetal harm.
- The concern with X-rays during pregnancy centers on high-dose, direct abdominal or pelvic imaging, not the low-dose, localized exposure from a dental X-ray.
Fear of a single bitewing or periapical film shouldn't be the reason a painful tooth or infection goes untreated. The dose math simply doesn't support that worry.
What ADA, ACOG, and Related Groups Recommend
US clinical bodies have converged on a consistent message: image only when it's necessary, and don't let pregnancy alone become a reason to delay diagnosis. The ADA's 2026 recommendations sharpen this further by emphasizing that both 2-D and 3-D imaging should follow the ALARA principle, meaning "as low as reasonably achievable," rather than a fixed schedule.
Key guidance points pregnant patients should know:
- The ADA and ACOG jointly affirm that oral health care, including indicated radiographs and local anesthesia, is safe throughout pregnancy.
- The 2026 ADA update shifts the focus to patient selection: an X-ray is taken when it will actually change treatment decisions, not as a routine step.
- ACOG's position discourages delaying necessary dental treatment during pregnancy, since untreated problems carry their own risks.
- Occupational radiation limits set by groups like the NCRP apply to dental staff exposed repeatedly over a career, a different calculation entirely from a single diagnostic image taken for a patient.
Shielding practices, including whether an abdominal apron is used, have evolved as more offices rely on digital sensors and collimation that already limit stray radiation. Your dental team can walk you through their specific approach.
When Dentists Actually Order X-Rays in Pregnancy
Dentists don't reach for X-rays reflexively. The decision follows a simple path: exam first, history second, and imaging only if it will change how your problem gets treated.
Common reasons an X-ray gets ordered during pregnancy include:
- Tooth pain that suggests a cavity reaching the nerve or an abscess.
- Suspected infection that needs to be located and sized before treatment.
- Facial or dental trauma from a fall or accident.
- Root canal therapy, where imaging confirms the canal anatomy and treatment success.
- Preoperative planning before an extraction or other surgical step.
Untreated dental infections carry real risks in pregnancy, including spread of infection and unnecessary pain and stress, which outweigh the minimal dose from a properly indicated X-ray.
Pro Tip: If you're dealing with a toothache during pregnancy, don't wait it out. A brief exam can often resolve the question of whether imaging is even needed.
How Your Dental Team Minimizes Dose and What to Ask
Modern dental offices already lean on technology that cuts radiation exposure well below older film-based systems. Digital sensors require a fraction of the dose of traditional film, and rectangular collimation narrows the X-ray beam to the area being imaged instead of scattering it more broadly.
Here's what to expect and what to communicate at your visit:
- Tell the front desk and your dentist that you're pregnant as soon as you schedule or check in.
- Confirm the specific reason imaging is being recommended and ask whether it will change your treatment plan.
- Ask what dose-reduction equipment the office uses, including digital sensors and collimation.
- Ask about the office's current apron and thyroid collar practices, since these vary by facility.
Pro Tip: A short, direct question like "Will this X-ray change what you do for my tooth today?" helps you and your dentist confirm the image is worth taking.
Does the Trimester You're In Change the Guidance?
Clinically necessary dental X-rays are considered appropriate in any trimester. The radiation risks that get attention in pregnancy research involve much higher cumulative doses than a dental image ever produces, so trimester timing doesn't change the safety math for routine dental radiographs.
That said, some judgment calls are reasonable:
- If an X-ray is purely elective, such as a routine recall image with no symptoms, it's fine to wait until after delivery.
- If pain, swelling, or suspected infection is present, imaging and treatment shouldn't be delayed regardless of trimester.
- When in doubt, your dentist's exam findings, not the calendar, should drive the decision.
Already Had an X-Ray Before You Knew You Were Pregnant?
Most people who had a dental X-ray before realizing they were pregnant have nothing to worry about. Diagnostic dental doses are low enough that a single exposure, even early on, is well below levels connected to pregnancy complications.
A few reassuring points and next steps:
- Contact your prenatal provider only if you had large or repeated exposures directly involving the abdomen or pelvis, which is a different scenario from a dental X-ray.
- Bring it up at your next prenatal visit if it would ease your mind, even when the science doesn't point to added risk.
- Resources like the MotherToBaby fact sheet are a good starting point if you want more detail before that appointment.
How CWD Dental Group Applies These Guidelines
CWD Dental Group treats pregnant patients using the same principles outlined by the ADA and ACOG: image only when it changes treatment, and never delay care for a painful or infected tooth. The practice offers same-day emergency dental appointments alongside its full range of general and family dentistry services.
What this looks like in practice:
- Digital X-ray equipment is used to keep any necessary imaging at a low dose.
- Front desk and clinical staff ask about pregnancy status during scheduling and intake so the visit is planned appropriately.
- Patients are encouraged to mention urgent pain, pregnancy status, and any recent prior X-rays before their appointment begins.
This mirrors the walk-in emergency workflows many dental offices use to triage urgent cases quickly.
A Note From the Author
If you're pregnant and putting off a dental visit because of X-ray worries, that fear is understandable but not backed by the dose numbers. A quick call to your dentist, paired with a heads-up to your prenatal provider if anything feels uncertain, is usually all it takes to move forward safely.

FAQ
Can I get dental X-rays at the dentist while pregnant?
Yes, dental X-rays are considered safe during pregnancy when your dentist determines imaging is clinically necessary. The ADA and ACOG both support diagnostic radiographs and routine dental treatment throughout pregnancy.
What do ADA guidelines say about X-rays during pregnancy?
The ADA's guidance states that dental radiographs are safe when clinically indicated and shouldn't be withheld simply because a patient is pregnant. Its 2026 update reinforces that imaging should follow the ALARA principle, meaning dentists order X-rays only when the result will change treatment.
What changed in the ADA's 2026 dental X-ray recommendations?
The 2026 ADA recommendations emphasize careful patient selection over routine imaging schedules for both 2-D and 3-D radiographs. This means dentists are guided to ask whether an image will actually change care before taking it, which benefits pregnant patients by limiting unnecessary exposure.
Is it safe if I had dental X-rays before I knew I was pregnant?
Yes, a diagnostic dental X-ray taken before you knew you were pregnant is very unlikely to pose a risk. According to MotherToBaby, typical diagnostic doses fall far below the levels associated with miscarriage or birth defects, so mention it at your next prenatal visit for peace of mind rather than out of concern.
