As a pediatrician, I am increasingly concerned by how often dental X-rays are presented to families as routine rather than selective. Let me be clear: that is not what current guidelines recommend.
The American Dental Association (ADA), along with the American Academy of Pediatric Dentistry, does not support taking dental X-rays on a fixed, automatic schedule for every child. Their guidance is explicit—X-rays should be performed only when there is a specific clinical indication. In other words, there needs to be a reason.
Yet in practice, many parents are told their child “needs” X-rays simply because it has been six months or a year. That is not evidence-based care. That is habit, and most times is motivated more by the bottom line than what is right, and safe, for your child.
Children are more sensitive to radiation than adults, and while the dose from a single dental X-ray is low, the issue is cumulative exposure over time. When imaging is done without a clear benefit, even small amounts of radiation become unnecessary risk. In medicine, we have a responsibility to follow the principle of minimizing exposure whenever possible.
This does not mean dental X-rays are unsafe or should be avoided altogether. When there is a legitimate concern—such as suspected cavities between teeth, dental pain, trauma, or evaluation of abnormal development—X-rays are an important and appropriate tool. In those situations, the benefit clearly outweighs the risk.
The problem is not the technology. The problem is overuse.
When X-rays are done “just because it’s time,” they are no longer serving the child’s best interest. They are serving a routine. And good pediatric care should never be driven by routine alone.
Parents should feel empowered to ask a simple question: what is the specific reason my child needs this X-ray today? If a clear, individualized answer is not provided, it is entirely appropriate to pause.
We should also be honest about what a careful clinical exam can accomplish. Not every healthy, low-risk child requires imaging at regular intervals. Many do not. By the way, this applies to adults as well.
As pediatricians, dentists, and parents, we share the same goal: protecting children’s health both now and in the future. That includes being thoughtful about every exposure, every test, and every intervention.
The American Dental Association (ADA), in collaboration with the U.S. Food and Drug Administration (FDA), has published a patient-selection guide that clearly states dental radiographs should be ordered based on individual clinical need, not as a routine, one-size-fits-all schedule. These guidelines emphasize that dentists should weigh the diagnostic benefits of an X-ray against the risks of cumulative radiation exposure over a child’s lifetime, using their professional judgment and the child’s specific caries risk, symptoms, and medical history to decide when imaging is truly necessary. In other words, the ADA’s own recommendations support a selective, indication-driven approach rather than automatic X-rays at every visit, aligning with the broader medical principle of using the lowest exposure needed to obtain essential diagnostic information.
Selective use of dental X-rays is not withholding care—it is practicing it responsibly.
