X-Rays & 3D Imaging

A clinical exam is essential, but it only shows the dentist what is visible to the eye. Dental x-rays and 3D imaging reveal what is happening between teeth, below the gumline, and inside the surrounding bone, where problems can develop quietly before any symptoms appear.

Finding decay, bone changes, cysts, or other abnormalities early usually means simpler, less involved treatment. Imaging is one of the most important diagnostic tools your dental team has.

The office uses digital x-rays, which use significantly less radiation than older film-based technology. Images appear on screen right away, where they can be enlarged, adjusted, and reviewed with you in the chair.

How often x-rays are taken depends on your history, risk level, and how long it has been since your last set. The dentist follows evidence-based guidelines and does not take x-rays on a fixed schedule for everyone. The frequency is personalized.

A panoramic x-ray (also called a panorex) captures the whole mouth in a single image: all the teeth, both jaws, the jaw joints, and the surrounding anatomy. It is commonly taken for new patients to set baseline records, and periodically after that to monitor changes over time.

Panoramic images are also useful for checking the position of wisdom teeth, looking at bone levels across the full arch, and spotting abnormalities that may not show on smaller x-rays.

Cone beam computed tomography (CBCT) uses a cone-shaped beam to capture a three-dimensional image of the teeth, jaws, bone, and surrounding anatomy. Unlike a conventional x-ray, a CBCT scan can be viewed in cross-section from any angle, allowing a detailed look at bone volume and density, nerve pathways, and the exact position of teeth.

CBCT is not part of routine dental care. It is ordered when three-dimensional information is needed to plan treatment. Common examples include dental implant planning, assessing impacted teeth, complex root canal anatomy, and evaluating jaw or bone conditions.

A CBCT scan delivers more radiation than a standard dental x-ray, so it is only used when the clinical benefit justifies it. The scan itself is non-invasive, usually takes under a minute, and involves no discomfort. Learn more about CBCT scans.
