Key takeaways:
- Dental X-rays reveal decay, jaw development issues, and hidden problems invisible to the naked eye
- Digital X-rays expose children to up to 90% less radiation than traditional film
- The AAPD recommends X-rays based on each child’s individual risk, not age alone
- OSO Pediatric Dentistry follows ALARA/ALADA safety principles at every visit
For many parents, the moment a dental assistant reaches for the X-ray sensor is the moment questions start forming. Is this necessary? Is it safe? How often does my child really need this? These are completely reasonable concerns — and they deserve clear, honest answers grounded in evidence rather than reassurance alone.
At OSO Pediatric Dentistry in Oxnard, dental radiographs are never taken as a formality. Dr. Elena Bedilo follows established guidelines from the American Academy of Pediatric Dentistry and recommends X-rays only when the diagnostic benefit is clear and the clinical picture calls for it.
What X-rays can see that a visual exam cannot
A dental X-ray reveals structures and problems that are entirely invisible to the eye, even during a thorough clinical examination.
When Dr. Bedilo examines your child’s teeth directly, she can evaluate the surfaces she can see — the tops and outer faces of teeth, the gums, and soft tissue. But decay most often begins between teeth, beneath the enamel surface, or at the base of a tooth near the root. None of these areas are visible without imaging.
Dental radiographs show early-stage cavities between teeth before they cause pain or visible damage, which means simpler treatment and less discomfort for your child. They also reveal how permanent teeth are developing beneath baby teeth, whether there is sufficient space for incoming teeth, and whether any teeth are impacted, missing, or forming abnormally.
Beyond cavities, X-rays allow Dr. Bedilo to evaluate bone levels around the roots, identify cysts, and assess jaw symmetry — all details that directly influence treatment decisions and long-term dental development.
How much radiation does a pediatric dental X-ray actually involve?
The radiation dose from a pediatric dental X-ray is among the lowest of any diagnostic imaging procedure.
Research published in a peer-reviewed study analyzing nearly 10,000 pediatric dental radiographs found that radiation doses were consistently low. A standard bitewing or dental X-ray produced an effective dose of approximately 0.77 microsieverts — an extremely small amount by any clinical measure. nih
To put this in perspective, the radiation exposure from a dental X-ray is comparable to a short airplane flight or a single day’s worth of natural background radiation from the environment. Osopediatricdentistry
Digital X-rays, which are used at OSO Pediatric Dentistry, expose children to significantly less radiation than traditional film X-rays — often up to 80 to 90 percent less. This technology allows for high-quality diagnostic images at minimal exposure. Osopediatricdentistry
The principles guiding every X-ray decision
Pediatric dental X-rays are governed by strict professional guidelines designed specifically to minimize exposure while preserving diagnostic accuracy.
The American Dental Association, the American Dental Hygienists’ Association, and the American Academy of Pediatric Dentistry all support the Image Gently campaign, a global initiative focused on safe and effective imaging of children. The campaign introduced the principle of As Low As Diagnostically Achievable — known as ALADA — which reflects the balance between image quality and minimizing radiation dose. Dimensions of Dental Hygiene
The AAPD guidelines emphasize that the timing of a radiographic examination should not be based upon the patient’s age alone, but upon each child’s individual circumstances, with every effort made to minimize radiation exposure. nih
At OSO Pediatric Dentistry, this means that X-rays are recommended based on your child’s specific cavity risk, the spacing of their teeth, their stage of dental development, and clinical findings from the exam — not on a fixed schedule applied to all patients equally.
How frequently will my child need X-rays?
Frequency is determined by each child’s risk profile, not by a one-size-fits-all schedule.
According to the AAPD, children with existing decay or high caries risk may need X-rays every six to twelve months, while children at the lowest risk for decay may go up to 24 months between posterior radiographs. Caries risk assessment is performed at every visit and can change over time based on many factors. The Tooth Ferry
For some children, a first set of X-rays may be recommended as early as age two or three if teeth have come in close together and decay cannot be ruled out visually. For others with well-spaced teeth and low risk, imaging may not be indicated until later. The AAPD does not set a specific age for a child’s first dental X-ray, instead directing pediatric dentists to recommend radiographs based on individual need rather than age alone.

What protective measures are used during the procedure?
The procedure itself takes only a few seconds per image. Children are seated comfortably, and a small sensor or film is positioned near the teeth being imaged. The X-ray is taken from a precise angle, and the exposure lasts less than one second.
In pediatric patients, less radiation is required for dental radiographs than in adults, because children’s bone and tissue structures are less dense. Exposure settings are adjusted accordingly — often reduced by half or more compared to adult parameters. Dimensions of Dental Hygiene
Protective aprons are used during imaging as an additional safeguard. Digital sensors used at OSO Pediatric Dentistry produce sharp, high-resolution images immediately — no waiting, no retakes from processing errors, and no unnecessary re-exposure.
What X-rays have detected that changed a child’s treatment plan
The value of a dental X-ray is most evident when it reveals something that would have been missed otherwise. Decay caught between two teeth at an early stage can often be treated with a simple filling rather than a more extensive procedure. A permanent tooth developing in the wrong position, caught early, can be guided with timely intervention rather than corrected later with more complex orthodontic work.
For children who avoid expressing pain — or who are too young to describe it — X-rays can identify problems before a parent would ever suspect them. This is one of the most important reasons routine radiographs, when clinically indicated, protect a child’s long-term oral health.
OSO Pediatric Dentistry also offers comprehensive dental exams that include a full evaluation of your child’s bite, jaw symmetry, and eruption pattern — giving families a complete picture of where their child’s dental development stands.
Addressing your concerns directly
If you have questions about whether X-rays are appropriate for your child at a given visit, Dr. Bedilo welcomes that conversation. Every recommendation made at OSO Pediatric Dentistry is based on clinical evidence and your child’s individual needs — not routine or habit.

Frequently asked questions
Question: Are dental X-rays safe for toddlers and young children?
Answer: Yes. Digital dental X-rays produce an extremely low radiation dose — comparable to natural background radiation from a single day outdoors. The AAPD and ADA both affirm their safety when clinically indicated.
Question: How do I know if my child actually needs an X-ray?
Answer: Your pediatric dentist evaluates your child’s cavity risk, tooth spacing, developmental stage, and clinical findings at each visit. X-rays are recommended only when the diagnostic benefit justifies the exposure.
Question: How often will my child need dental X-rays?
Answer: The AAPD recommends every six to twelve months for high-risk children and up to every 24 months for those at low risk. The schedule is personalized, not fixed.
Question: Do digital X-rays expose children to less radiation than older methods?
Answer: Yes. Digital radiography reduces radiation exposure by up to 80 to 90 percent compared to traditional film X-rays, while producing higher-quality images.
Question: What can a dental X-ray detect that a visual exam cannot?
Answer: Cavities between teeth, decay beneath the gum line, developing permanent teeth, impacted or missing teeth, bone levels, and jaw development — none of which are visible during a standard clinical examination.
