Are Dental X-Rays Dangerous? Here’s What You Really Need to Know

That brings us to a common myth: Dental X-rays are harmful because of radiation exposure.

The truth? Dental X-rays are extremely safe. In fact, they emit some of the lowest radiation levels in the medical field and play a crucial role in early detection and prevention of oral health issues.

At Archer Dental, we believe that informed patients make the best decisions. So let’s break down this myth and show why dental X-rays are not only safe—but also essential.

Myth: Dental X-Rays Are Harmful Because of Radiation Exposure

Truth: Dental X-Rays Emit Extremely Low Radiation and Are Safe Under Strict Protocols

Yes, dental X-rays involve a small amount of radiation—but the key word here is small. A single bitewing X-ray exposes you to about 0.005 millisieverts (mSv) of radiation. For comparison, a cross-country flight exposes you to around 0.03–0.05 mSv. You’d get more radiation from spending a day in the sun or eating a few bananas (really—bananas contain naturally radioactive potassium).

We also use digital X-rays at Archer Dental, which emit up to 90% less radiation than traditional film. Combine that with lead aprons, thyroid collars, and tailored treatment plans, and your exposure stays well within safe limits.

In short, while radiation sounds intimidating, the actual risk from dental X-rays is virtually nonexistent—especially when weighed against the benefits of early detection and timely treatment.

Why X-Rays Are So Important for Your Oral Health

Dental X-rays let us see what’s happening below the surface—between teeth, inside the bone, and under the gums. Many dental issues start silently, with no visible symptoms. Without X-rays, we’d be flying blind when it comes to diagnosing cavities, infections, or developmental concerns.

They help us catch small problems before they turn into big ones, like spotting decay between teeth before it becomes a full-blown cavity or identifying bone loss due to gum disease before teeth start shifting or loosening. In children and teens, X-rays help us monitor growth, eruption patterns, and orthodontic needs.

With the insights we gain from X-rays, we’re able to provide better, more proactive care—often saving patients from discomfort, time-consuming procedures, and higher costs down the line.

How Often Should You Get Dental X-Rays?

The frequency of dental X-rays depends on your age, oral health status, risk factors, and history of dental work. There’s no universal rule, but we always take a personalized approach at Archer Dental.

New patients typically get a full set of X-rays to establish a baseline, while returning patients may only need bitewings every 12 to 24 months if they’re considered low-risk. Those with a history of gum disease, frequent cavities, or other concerns may need X-rays more often. Kids and teens often require more frequent imaging to monitor development.

Rest assured—we never take unnecessary X-rays. Every image we capture has a clear clinical purpose, and we’ll always explain why it’s being done.

Are There Long-Term Risks from Repeated Dental X-Rays?

Understandably, many people worry about cumulative exposure from repeated X-rays. But even over a lifetime, the amount of radiation from dental imaging remains incredibly low.

When compared to the benefits—such as detecting early signs of infection, preventing tooth loss, or spotting jaw issues—the minimal exposure is well worth it. Every reputable dental organization, from the American Dental Association to the FDA, agrees: dental X-rays are safe when proper protocols are followed.

And yes, we follow those protocols to the letter. Your safety and trust are our top priorities.

What We Do to Keep You Safe During X-Rays

At Archer Dental, your peace of mind matters. That’s why every time we take dental X-rays, we use:

• Digital X-ray technology that dramatically reduces exposure
  
  
• Protective shielding, including lead aprons and thyroid collars
  
  
• Selective imaging, meaning we only take X-rays when necessary based on your needs
  
  
• Strict ADA and FDA safety protocols to ensure your exposure remains as low as reasonably achievable (the ALARA principle)
  
  

Our team also reviews your imaging history and, whenever possible, avoids repeating films that were recently taken elsewhere. We believe in transparency, and we’re always happy to explain our safety measures and how they protect you.

The Bottom Line: Dental X-Rays Are Safe and Incredibly Useful

Dental X-rays are not harmful when used properly—and they’re a critical part of maintaining your oral health. They allow us to diagnose problems early, prevent major dental work, and ensure your smile stays strong for years to come.

Instead of fearing the “R” word, you can feel confident knowing that modern dental imaging is one of the safest diagnostic tools available in medicine today.
