Every parent wants to know their child’s smile is truly healthy, not just on the surface. But some of the most common childhood dental problems — early cavities between teeth, developing tooth crowding, or infections forming beneath the gumline — are invisible to the naked eye. That’s exactly why kids dental x-rays are one of the most important tools in pediatric dental care, giving dentists a complete picture of what’s happening inside your child’s mouth long before a problem becomes painful or expensive to treat.
At Little Roots Pediatric Dental in Westbury, New York, our board-certified pediatric dentists Dr. Jessica Barzideh and Dr. Sunaina Vohra use advanced digital x-ray technology to monitor your child’s oral development safely and accurately. As part of our preventive dentistry approach, we recommend x-rays only when they provide meaningful diagnostic benefit — and we always take the time to explain exactly what we’re looking for and why.
What Are Kids Dental X-Rays and Why Are They Important?
Children’s dental x-rays are diagnostic images that allow our team to see areas of the teeth, roots, and jaw that a standard visual exam simply cannot reach. They are an essential part of any comprehensive pediatric dental visit, helping us track growth, catch problems early, and plan the right care at the right time.
X-rays help us detect several concerns that would otherwise go unnoticed, including:
- Hidden cavities: Decay that forms between teeth or beneath the surface before it appears as a visible spot
- Tooth development: Confirming that permanent teeth are forming correctly and have adequate room to emerge
- Root and bone health: Identifying infections, cysts, or bone loss that could affect long-term oral health
- Bite and alignment: Evaluating spacing concerns early so orthodontic issues can be addressed before they worsen
Catching these issues early makes a significant difference. Children treated for small cavities or minor misalignments typically require less invasive care than those whose problems are identified later. Paired with treatments like dental sealants and dental fluoride, x-rays give us the complete picture we need to keep your child’s smile strong for life.
Are Dental X-Rays Safe for Children?
This is one of the most common questions we hear from parents in Nassau County, and the answer is yes. Children’s dental x-rays are very safe when performed with modern digital equipment and appropriate protective measures. Digital x-rays expose children to significantly less radiation than traditional film x-rays, and the overall exposure is comparable to what your child naturally receives from the environment on any given day.
We follow the ALARA principle — As Low As Reasonably Achievable — which means we recommend x-rays only when the diagnostic benefit justifies them. Lead aprons and thyroid collars are always used during imaging to provide an additional layer of protection. According to the American Academy of Pediatric Dentistry, individualized risk assessments should guide how often children receive x-rays, rather than fixed schedules. At Little Roots, we follow exactly this approach.
What to Expect During Your Child’s Dental X-Rays
We understand that dental visits can feel unfamiliar for young children, so our team takes care to make every part of the experience as comfortable as possible. Before anything begins, we explain the process in simple, age-appropriate language so your child knows exactly what to expect.
During the x-ray, your child will sit comfortably while a small sensor is positioned in their mouth for a few seconds to capture each image. The entire process usually takes only a few minutes and causes no discomfort. Our team shows children the images afterward, which often turns the moment into something they find genuinely interesting.
For children who experience anxiety during dental visits, our sedation dentistry options can make the entire appointment smoother and more relaxed. We also serve children with special needs and are experienced at adapting our approach to meet each child’s individual comfort level.

Frequently Asked Questions Pediatric Dental X-Rays
How often should children get dental X-rays?
The frequency of dental X-rays for children depends on their individual oral health, risk factors, and developmental stage. The American Academy of Pediatric Dentistry recommends that children at high risk for cavities may need bitewing X-rays (showing the crowns of teeth) every 6 months, while those with lower risk might need them only every 12-24 months. Panoramic X-rays, which show the entire mouth, are typically recommended every 3-5 years to monitor growth and development. For children with specific dental concerns like impacted teeth or suspected abnormalities, additional targeted X-rays might be necessary. Our pediatric dental team follows the ALARA principle (As Low As Reasonably Achievable) for radiation exposure, meaning we recommend X-rays only when the diagnostic benefits outweigh the minimal risks, customizing the frequency based on each child’s specific needs rather than following a rigid schedule.
Are dental X-rays safe for children?
Dental X-rays are very safe for children when proper safety protocols are followed. Modern digital dental X-ray technology uses significantly reduced radiation levels compared to traditional film X-rays—up to 80-90% less radiation. To put this in perspective, a set of four bitewing X-rays exposes a child to less radiation than they would receive during a day of normal background radiation from the environment. At our practice, we take additional precautions to minimize exposure by using lead aprons with thyroid collars, fast digital sensors that require less radiation time, and precise equipment that targets only the necessary areas. We also carefully determine the need for X-rays based on each child’s individual risk factors rather than taking routine X-rays regardless of need. These protective measures ensure that the minimal risk is far outweighed by the significant diagnostic benefits that help us provide the best possible dental care.
What types of dental problems can X-rays detect that visual exams cannot?
Dental X-rays reveal numerous important conditions that remain invisible during visual clinical examinations, making them an essential diagnostic tool. X-rays can detect cavities between teeth (interproximal decay) before they become visible or symptomatic, allowing for earlier and less invasive treatment. They show decay beneath existing fillings or under the gumline that cannot be seen during a regular exam. X-rays are crucial for evaluating proper tooth development, identifying missing, extra, or impacted teeth, and assessing the position of unerupted permanent teeth. They help detect bone diseases, tumors, or cysts in the jaw that show no external symptoms. X-rays also reveal infections at the tooth root or bone level, allow assessment of injuries after dental trauma, and help determine if orthodontic treatment might be needed. Without X-rays, these conditions might remain undetected until they cause pain or require more extensive treatment.
How should I prepare my child for their first dental X-ray?
Preparing your child for their first dental X-ray helps ensure a positive experience. Start by explaining the process in simple, non-frightening terms—describe it as a special camera that takes pictures of their teeth that even the dentist cannot see with just their eyes. Avoid using words like “radiation” or “shot” that might cause unnecessary anxiety. You can show them pictures of dental X-ray equipment online or read children’s books about dental visits that include X-rays. Reassure them that the procedure is quick (taking just seconds) and doesn’t hurt at all, though they’ll need to hold very still like a statue for a moment. If your child has concerns, encourage them to ask questions during their appointment—our team is experienced in explaining procedures to children in age-appropriate ways. On the day of the appointment, having your child wear a two-piece outfit makes it easier to place the protective apron while keeping them comfortable.
Why do children need different types of dental X-rays at different ages?
Children need different types of dental X-rays at different developmental stages to address age-specific concerns and monitor their rapidly changing dentition. For very young children (2-3 years), occlusal X-rays might be taken to examine front teeth development and detect early decay. As primary teeth develop contact points (ages 3-6), bitewing X-rays become important for detecting cavities between teeth. Around ages 6-8, when children begin losing baby teeth, panoramic and periapical X-rays help monitor the development and positioning of permanent teeth coming in. During mixed dentition years (ages 6-12), panoramic X-rays track jaw growth and tooth eruption patterns, helping identify potential orthodontic needs early. For teenagers, wisdom tooth evaluation becomes important, often requiring panoramic X-rays to assess their development and positioning. This age-appropriate approach ensures we gather critical diagnostic information while minimizing radiation exposure, focusing on the specific developmental concerns most relevant to each stage of childhood.
