Many families ask us the same question during checkups: Are dental X-rays really necessary, and are they safe, especially for children? It’s a fair concern. At our Olympia, WA, dental office we understand that parents want reassurance before approving any procedure. The good news is that modern digital dental X-rays are incredibly safe, quick, and accurate. They play a vital role in identifying and addressing small issues before they escalate into major problems.
In this guide, we’ll walk you through what digital X-rays are, why we use them, how we minimize radiation exposure, and what you can expect during your visit with Dr. Suneet S. Bath, DMD, and our team.
What Digital Dental X-Rays Are
Digital dental X-rays use a small electronic sensor instead of traditional film to capture detailed images of your teeth and jaw. These images appear instantly on our screen, making it easier for us to identify even the smallest areas of concern and explain what we see.
This technology is part of our commitment to modern, comfortable, and precise care for families throughout Olympia. Unlike older systems, digital imaging uses a fraction of the radiation—while delivering sharper, clearer pictures.
- Instant, high-quality images for early detection of problems
- Faster, more comfortable process with no chemical processing
- Easier sharing between our dental team and any specialists involved in care
Types of Dental X-Rays We Use
Each type of dental X-ray helps us monitor your child’s developing teeth and detect issues early. We choose imaging based on your child’s age, growth, and specific preventive needs.
- Bitewing X-Rays: These show the upper and lower teeth together, helping us detect cavities between teeth and monitor bone levels around the gums. They’re most common during routine exams.
- Periapical X-Rays: These capture the entire tooth—from crown to root—to evaluate infections, fractures, or root problems that aren’t visible during a regular exam.
- Panoramic X-Rays: A panoramic X-ray shows a full view of the jaw, teeth, and surrounding bone. It’s often used for orthodontic planning, evaluating wisdom teeth, and detecting cysts or issues with the jaw joint.
- CBCT (3D Imaging): When we need even greater precision, CBCT (cone-beam computed tomography) provides 3D detail. We use it selectively for complex cases like implant planning or evaluating jaw joint health.
How Often You or Your Child Needs X-Rays
There’s no single rule for how often someone needs dental X-rays. We tailor the schedule for each patient based on their age, health, and individual risk factors. Children and teens may require X-rays more frequently because their teeth and jaws are still developing, and decay can progress more rapidly in smaller teeth.
Routine dental exams and cleanings go hand-in-hand with X-rays to maintain healthy smiles. During these visits, your dentist can identify early signs of decay, monitor growth, and ensure your child’s teeth and gums stay strong between appointments.
We base frequency on:
- Age and stage of dental development
- History of cavities or restorative treatment
- Diet and home care habits
- Whether you have ongoing orthodontic or gum concerns
We always explain why an image is recommended and what information it provides before taking it. Transparency is crucial in enabling families to make informed, confident decisions about their care.
Factors That Influence Frequency
Even among patients of the same age, X-ray needs can differ. We assess each person individually to create the safest and most effective diagnostic plan tailored to their specific needs.
- Cavity risk level and past oral health history
- Presence of fillings, crowns, or other restorations
- Home care routines and fluoride use
- Medical conditions or medications that affect oral health
Our goal is simple: take X-rays only when they add valuable information to your treatment or help us catch an issue early.
Safety and Radiation in Plain Language
We follow the ALARA principle—“as low as reasonably achievable”—for every image we take. Digital X-rays use up to 90% less radiation than traditional film-based systems, and we continually invest in the most advanced equipment to further reduce exposure.
At Impressions Dentistry, we believe education builds trust. We’ll always explain why an image is needed, what it shows, and how it benefits your oral health.
What We Do to Minimize Exposure
Safety and comfort guide every part of our process. Our imaging protocols are designed to deliver clear results with minimal exposure.
- Use of modern digital sensors and controlled settings for every age
- Lead aprons and thyroid collars when indicated
- Only the essential number of images for your specific needs
Because the process is quick—just a few seconds per image—your overall exposure stays exceptionally low.
When We Recommend CBCT (3D Imaging)
Sometimes, 2D X-rays aren’t enough. In such cases, CBCT imaging provides a detailed, three-dimensional view of teeth, jaw structure, and airway spaces. Dr. Bath recommends CBCT only when it’s necessary for precise diagnosis or treatment planning.
We might use CBCT for:
- Complex tooth development or impacted wisdom teeth
- Evaluating jaw joint issues or bone health
- Planning implants or other advanced procedures
Our digital X-rays and CBCT systems are designed for safety and efficiency, so even advanced imaging feels comfortable and quick.
What to Expect During Dental X-Rays at Impressions Dentistry
We make X-rays simple, safe, and stress-free for every age group. During your visit, one of our friendly dental assistants will place a small sensor in your mouth and ask you to bite down gently while the image is captured.
Each image takes only seconds, and you’ll be able to relax as we review the results together on-screen. Dr. Bath explains what we’re seeing in clear, easy-to-understand terms so you can make informed choices about your care.
Helping Kids Feel Comfortable
For our youngest patients, patience and a positive experience are everything. We use gentle “tell-show-do” techniques to explain each step before it happens and celebrate small successes along the way.
- Using small, flexible sensors designed for kids’ comfort
- Keeping the process quick and encouraging breaks if needed
- Creating a friendly, supportive environment that builds confidence
Our children’s dentistry team makes sure every child leaves with a smile—and no fear about their next visit.
How X-Rays Guide Early, Conservative Care
Dental X-rays are essential for prevention. They enable us to identify and resolve issues early—long before you experience discomfort or notice visible changes. This means simpler, less costly, and more comfortable treatment options.
Here are just a few ways we use X-rays in family dentistry:
- Detecting cavities between teeth before they become painful
- Monitoring gum health and bone support
- Checking growth and eruption patterns for children and teens
- Planning precise treatments like fillings, crowns, or orthodontic care
By combining X-rays with preventive exams and cleanings, we can help you protect your smile for life. You can learn more about family dentistry in Olympia and how we tailor our care to suit every age.
