Pediatric Dental X-Rays

For many parents, the words “X-ray” and “radiation” bring an immediate wave of concern. We understand—your child’s safety is your top priority, and it’s ours too. At Junior Smiles of Stafford, we’ve walked alongside hundreds of families who shared the same hesitation. This guide is designed to replace that fear with confidence by answering every question you may have about dental X-rays for children, from why they’re needed to how we keep the process safe and stress-free.

First Things First: Why a Visual Check-Up Isn’t Always Enough

At first glance, your child’s teeth may look perfectly fine. But much like an iceberg, only part of the story is visible above the surface. Cavities, infections, and developmental issues often begin where the eye cannot see—between teeth, beneath the gumline, or deep inside the jawbone.

That’s where dental X-rays come in. Think of them as our superhero vision, allowing us to spot tiny problems early before they turn into painful, costly issues. A small cavity between molars, for instance, might go undetected for months with the naked eye, but an X-ray can reveal it right away, giving us the chance to treat it while it’s still minor.

This is one of the most important uses of dental radiographs: prevention. And prevention is always gentler, safer, and less expensive than waiting for problems to grow.

The Big Question: Are Dental X-Rays Safe for My Child?

This is the heart of every parent’s concern, and the answer is reassuring: yes, dental X-rays are safe for children—especially with the modern technology we use at Junior Smiles of Stafford.

We know radiation can sound frightening, but the truth is that the exposure from dental X-rays is extremely low. In fact, it’s far less than what your child would naturally receive just from being outdoors in the sun or taking a short airplane ride.

A Realistic Look at Radiation (It’s Less Than You Think)

To put things in perspective, a standard set of four bitewing X-rays exposes your child to less radiation than a two-hour airplane flight. It’s also less than the amount of natural background radiation we all receive in a single day just by living on Earth.

Exposure Type	Radiation Dose (µSv)
4 Dental Bitewing X-Rays	~5 µSv
1 Day of Natural Background Radiation	~8 µSv
Cross-Country Flight	~30 µSv

So when we talk about taking dental radiographs, we’re talking about exposures so small they’re considered negligible—especially when compared to the tremendous benefit of detecting and preventing major dental issues early.

Our ALARA Promise: “As Low As Reasonably Achievable”

We follow a professional principle known as ALARA, which means As Low As Reasonably Achievable. This is more than just a slogan—it’s a promise. At Junior Smiles of Stafford, we only take X-rays when absolutely necessary, we use the lowest possible radiation dose, and we rely on advanced digital X-ray equipment that is designed to minimize exposure while maximizing clarity.

This careful approach ensures your child receives all the benefits of modern imaging technology with none of the unnecessary risk.

An Update on Lead Aprons: Following the Latest Science

You may remember wearing a lead apron when you had X-rays as a child. For decades, it was standard practice. However, the science has changed. Leading organizations like the American Academy of Pediatric Dentistry (AAPD) now advise that with today’s tightly focused, ultra-low-dose X-ray beams, lead aprons are no longer necessary—and in some cases, they can even interfere with getting a clear image.

This doesn’t mean we’re removing safeguards. It means technology has advanced so much that the scatter radiation risk is virtually eliminated. At Junior Smiles, we stay current with these evolving guidelines, ensuring your child benefits from the safest, most evidence-based care available.

X-Rays at Every Age: What We’re Looking For

Every stage of your child’s dental journey has its own needs, and X-rays allow us to tailor care precisely to those needs.

Toddlers & The First Baby Teeth (Ages 1–5)

When your little one first visits us, X-rays may be recommended if we suspect decay between baby teeth or need to check jaw development. Early imaging can confirm that teeth are erupting properly and ensure no developmental concerns are hiding below the surface. For some children, especially around age five, a simple infant teeth X-ray or x-ray of 5 year olds’ teeth can give us valuable reassurance.

The Gappy Grin Years & Mixed Dentition (Ages 6–12)

This is a critical window when baby teeth and permanent teeth are working together to shape your child’s smile. X-rays help us monitor the eruption of new teeth, identify crowding issues, and check for cavities on freshly erupted molars. By taking a mixed dentition radiograph at the right time, we can catch orthodontic issues early and guide you toward solutions before they become complex.

Teens & The Final Smile (Ages 13+)

For teenagers, the focus often shifts to wisdom teeth, jaw development, and long-term orthodontic health. X-rays help us see whether wisdom teeth are likely to erupt properly or become impacted, and ensure your teen’s permanent smile is strong and healthy.

Our Kid-Friendly X-Ray Process at Junior Smiles of Stafford

We know that unfamiliar machines can feel intimidating for children. That’s why our process is designed to be simple, fast, and—believe it or not—fun.

Before You Arrive: How to Talk to Your Child

The way you describe the appointment makes a big difference. Instead of saying “X-ray,” try calling it a “tooth camera.” You can explain: “We’re going to take some special pictures of your teeth so the dentist can count them and keep them super healthy.”

Our hygienist Sarah often lets kids “help” by pressing a button on the control panel from a safe distance. This small moment of participation can turn nerves into excitement.

In the Chair: Fast, Easy, and Fun

When it’s time, your child will bite gently on a small sensor—what we sometimes call the “plastic cracker.” The entire process takes just seconds, and most kids are surprised by how quick and easy it is. Our team is trained in working with children of all temperaments, including those with special needs, and we always celebrate their bravery with plenty of praise and encouragement.
