Dental X-Rays During Pregnancy Are Safe
Yes, dental X-rays can and should be performed during pregnancy when clinically indicated—the radiation exposure is far below any threshold that could harm the developing fetus. 1, 2
Radiation Exposure Levels
The radiation doses from dental imaging are extremely low and pose negligible risk:
Fetal radiation doses range from 0.009 to 6.9 μGy across all dental imaging modalities (intraoral, panoramic, cephalometric, and CBCT), which represents less than 1% of the annual public dose limit of 1 mSv 2
These doses are well below the teratogenic threshold and have deterministic (not stochastic) effects, meaning they are unlikely to cause birth defects at the exposure levels used in dental radiography 3
Even without lead shielding, the radiation exposure remains minimal and safe 2
Clinical Recommendations
Dental imaging should never be restricted or postponed during pregnancy if clinically justified 4, 2, 5:
The examination must be indication-oriented and patient-specific, following the ALADAIP principle ("as low as diagnostically acceptable, being indication-oriented and patient-specific") 1
All gestational ages are safe for dental radiography when proper technique is used 5
Dental radiographs may be performed safely with appropriate shielding, though shielding is not strictly necessary given the already negligible exposure levels 2, 6
Optimal Timing Considerations
While dental X-rays are safe throughout pregnancy:
Nonemergent interventions are best provided between 14 and 20 weeks' gestation for maternal comfort and optimal fetal safety 6
Emergency and preventive dental care should not be delayed regardless of trimester 6
Common Pitfalls to Avoid
Do not deny or postpone clinically necessary dental imaging due to pregnancy concerns 2:
The risk of untreated dental disease (including periodontal disease associated with preterm birth) outweighs the negligible radiation risk 5, 6
Pregnancy is never a reason to avoid a clinically justified dental radiographic examination 2
Practitioners must be able to justify the examination but should not withhold necessary diagnostic imaging 1
Lead Shielding
While lead shields can reduce exposure further (foetal doses from 0.009-6.9 μGy to 0.005-2.1 μGy), their use is considered optional rather than mandatory given that unshielded doses are already far below harmful thresholds 2
