Yes. Dental X-rays use a very small, targeted amount of radiation and are considered safe when recommended for a specific diagnostic reason. They help dental professionals identify problems that may not be visible during a regular examination, including cavities, infections, bone loss, and changes around dental implants.

At the office of Barry P. Levin, DMD, PC, in Jenkintown, PA, we use digital dental X-rays and advanced dental imaging to evaluate patients throughout Montgomery County, Bucks County, Philadelphia, and surrounding communities. Imaging supports treatment planning for periodontal disease, dental implants, bone augmentation, and other oral health needs.

Key Takeaways

• Dental x-rays use extremely low radiation, and digital x-rays cut that exposure further compared to older film
• Dental x-ray safety protocols, including lead aprons, protect patients of every age
• A dental CT scan and dental cone beam CT scan give a 3D view valuable for implant and periodontal planning
• How often you need dental x-rays depends on your history and risk factors, not a fixed schedule

How Safe Are Dental X-Rays?

Dental x-rays are among the safest imaging tools in medicine. The radiation from a single dental x-ray is extremely low, and the goal is always to use the smallest dose that still produces a clear image. Dental x-ray safety comes down to that principle: the lowest dose possible, and only taking x-rays for a genuine diagnostic reason.

Digital Dental X-Rays: Lower Radiation, Better Detail

Digital dental x-rays have largely replaced film in modern practices. Compared to film, digital dental x-rays can reduce radiation exposure by as much as 90 percent, while producing sharper, easier-to-review images. Digital dental x-rays also process instantly, meaning less time in the chair.

Dental X-Ray Radiation in Perspective

Patients often ask how dental x-ray radiation compares to everyday exposure. A single dental x-ray delivers roughly the same radiation as a few hours of daily life, and even a full set compares to a cross-country flight. We use lead aprons, thyroid collars, and quick exposure times to keep dental x-ray radiation as low as reasonably possible.

Dental CT Scans and Cone Beam CT: A Closer Look

A dental CT scan, most often a dental cone beam CT scan (CBCT), goes beyond a flat, two-dimensional image. In our Jenkintown office, cone beam CT gives us a 3D view of the jaw, teeth, and bone in one low-dose scan. The biggest benefit of a dental CT scan is precision: before placing a dental implant or planning periodontal surgery, we can see nerves, sinuses, and bone density ahead of time, supporting more accurate, less invasive treatment.

Dental X-Rays During Pregnancy

Dental x-rays during pregnancy are safe when necessary, since a lead apron and thyroid collar shield the abdomen and thyroid from radiation. Routine x-rays are often postponed until after delivery, but active infections or pain needing diagnosis can still be imaged safely. Let your dental office know if you’re pregnant before any imaging.

How Often Do You Need Dental X-Rays?

How often do you need dental x-rays? It depends on your individual risk for cavities, gum disease, and other issues, not a one-size-fits-all timeline. Patients with a history of decay or periodontal disease may need imaging more often, while those with consistently healthy checkups may go longer between x-rays.

The Benefits of Dental X-Rays and Imaging

The benefits of dental x-rays go well beyond spotting cavities. Imaging reveals:

• Bone loss from gum disease
• Infections below the gumline
• Cysts and other hidden issues
• The exact position of teeth and roots

All of this is visible before symptoms appear. For patients considering dental implants or periodontal surgery, dental imaging allows us to plan treatment with precision instead of estimating.

FAQs

Do dental x-rays hurt or cause side effects?

No. Dental x-rays are painless, with no side effects at the radiation levels used in dental imaging.

Can I refuse dental x-rays at my appointment?

Yes, though your dentist may not be able to safely diagnose certain issues without them. Ask your provider why a specific x-ray is recommended.

How long does a cone beam CT scan take, and is it uncomfortable?

A cone beam CT scan typically takes under a minute and is painless. You’ll sit or stand still while the scanner rotates around your head, similar to a panoramic x-ray.

Will I need a cone beam CT scan before every dental implant?

Not always, but it’s common for implant planning. Dr. Levin will discuss whether one is needed at your consultation.
