Panoramic Dental X-rays When and Why You Need Them

Have you been asked by your dentist to get a panoramic dental X-ray? Wondering what it’s for and whether it’s safe? Panoramic dental X-rays are a key diagnostic tool in modern dentistry, offering a comprehensive view of the jaws, teeth, and joints in a single, quick, and highly detailed image. In this article from Dalili Medical, we provide you with a complete guide to panoramic dental X-rays: what they are, how they’re done, their importance, common uses, safety, and when they’re recommended.

✅ What Is a Panoramic X-Ray?

A panoramic dental X-ray is a special type of X-ray that captures a wide-angle image of the entire mouth in a single shot, including:

Upper and lower teeth
Upper and lower jawbones
Temporomandibular joints (TMJ)
Sinus cavities
Tooth roots and surrounding bone structures

It’s commonly used in dental clinics to evaluate complex issues that may not be visible in a regular oral exam.

When Is a Panoramic X-Ray Recommended?

Your dentist may recommend a panoramic X-ray in the following situations:

Before starting orthodontic treatment or dental implants
To detect impacted teeth (like wisdom teeth)
To assess jaw fractures or abnormalities
To diagnose infections or abscesses
To monitor tooth development in children or teens
To evaluate TMJ disorders
To screen for oral tumors or cysts

✅ How Is a Panoramic X-Ray Performed?

The procedure is quick, simple, and painless.

Preparation:

You may be asked to remove jewelry, glasses, or any metal objects.
A lead apron is worn to protect your body from radiation.

Positioning:

You will stand or sit while gently biting on a plastic piece to stabilize your head.
Your head and jaw must be kept still during the scan.

Imaging:

The X-ray machine rotates around your head in a half-circle.
The scan takes about 10–20 seconds, and the image is ready instantly on a digital screen.

✅ Full view of the mouth and jaw in one image
✅ Non-invasive and takes just a few seconds
