Digital X-Rays – DFW Metroplex

At Bear Creek Family Dentistry, we use modern digital X-ray technology as part of every comprehensive exam. Your initial examination will be performed by a dentist, who may request that X-rays be taken to help in understanding previous dental work that has been performed, as well as in evaluating the current state of your teeth, roots, and surrounding bone. Digital X-rays allow us to detect issues that aren't visible to the naked eye — including cavities between teeth, bone loss, and developing problems beneath the gumline — so we can address them early and keep your smile healthier for longer.

Digital radiography has largely replaced traditional film X-rays in modern dental offices. The core difference: instead of exposing a piece of photographic film and waiting for it to develop in a darkroom, a small electronic sensor captures the image and displays it on a chairside monitor in seconds. That speed benefits both the clinical workflow and you as a patient.

How Digital X-Rays Work

A small sensor — roughly the size of a traditional film tab — is placed inside your mouth, one position at a time. The X-ray unit emits a brief, targeted beam. The sensor transmits the image to a computer almost instantly, where the dentist can view it at full size, zoom in, and adjust brightness or contrast as needed. The entire process for a full set of images typically takes 10–15 minutes and requires no waiting for film to develop.

Because the images are digital files, they're stored in your patient record and easy to compare at future visits. Subtle changes — a small area of early decay, a slight shift in bone height — become much more visible when two images taken a year apart are placed side by side.

What Digital X-Rays Can Detect

Certain problems simply cannot be found through a visual exam alone. Digital X-rays give the dentist a clearer picture of:

• Cavities forming between teeth or underneath existing fillings
• Early signs of bone loss around the roots, which can indicate gum disease
• The position and development of wisdom teeth
• Infections or cysts forming at the root tip
• Changes in the jawbone structure over time
• The fit and condition of crowns, bridges, and other restorations

Catching these issues earlier generally means simpler, less costly treatment. A cavity spotted when it's confined to the enamel can often be addressed with a small filling; the same cavity left undetected can eventually require a crown or root canal.

Radiation Exposure

One of the most common concerns patients raise is radiation. Digital X-rays use significantly less radiation than traditional film — generally cited in dental literature as roughly 70–80% less, though the exact figure varies by equipment and technique. To put it in perspective, the exposure from a standard set of dental X-rays is comparable to the background radiation a person receives during a short airplane flight.

Lead aprons and, when appropriate, thyroid collars are standard protective measures. If you have specific concerns about radiation — including if you are pregnant — let the front desk or the dental team know before your appointment so they can discuss the most appropriate imaging protocol for your situation.

How Often Are X-Rays Taken

Frequency depends on your individual dental history and current risk factors, not a fixed schedule applied to every patient. Adults with a history of decay or gum disease may need X-rays more frequently than someone with consistently healthy checkups. For most adults without notable risk factors, bitewing X-rays are commonly taken once a year, with a more complete set taken less often. The dentist makes that determination based on your specific circumstances — patients in the Dallas area who are new to Bear Creek Family Dentistry will typically have a full set taken at their first visit so the team has a complete baseline.

Frequently Asked Questions

**Do dental X-rays hurt?** No. The sensor can feel slightly uncomfortable if placed near sensitive tissue, but the process itself is painless. The actual exposure lasts less than a second per image.

**How long does getting X-rays take?** A standard set of bitewing X-rays takes roughly 5–10 minutes. A full-mouth series, which captures more angles, typically takes 10–15 minutes.

**Are digital X-rays safe if I'm pregnant?** Dental X-rays are generally deferred during pregnancy unless there's a clinical reason they can't wait. Always inform the dental team if you are pregnant or think you might be — they will adjust the approach accordingly.

**Why does the dentist need X-rays if my teeth feel fine?** Many dental problems — early decay, bone loss, cysts — cause no noticeable symptoms until they've progressed significantly. X-rays allow the dentist to find and treat problems while they're still manageable, not after they've caused pain.

**Will my X-ray images be shared with other providers if I need a referral?** Digital images are stored in your patient record and can be exported electronically if you're referred to a specialist or if you request a copy for another provider, eliminating the need to retake images unnecessarily.
