So what exactly is a panoramic X-ray, and how does it differ from the X-rays taken during a typical dental visit?

A panoramic X-ray works much like a panoramic photo taken from a mountain top—it captures a wide, comprehensive view. Instead of focusing on just a few teeth, this type of X-ray shows your entire set of teeth in a single image. It also reveals the bones that support your teeth, your full upper and lower jaw, both jaw joints, and even parts of your sinuses, skull, and upper spine.

Getting a panoramic X-ray (often called a “pano”) is quick and comfortable. Unlike traditional dental X-rays, you don’t have to bite down on small film holders. Instead, you’ll stand—or sit if needed—while resting your chin on a support and gently biting on a small positioning guide.

The machine then slowly moves around your head, capturing a complete image of your dental structures. This broad view allows your dental team to evaluate many aspects of your oral health all at once.

What’s the difference between a panoramic x ray and regular x rays?

About once a year, most patients should have routine check-up X-rays called bitewings. These are close-up images of the back teeth, which are the most common areas for cavities to develop.

A panoramic X-ray doesn’t offer the same level of fine detail as bitewings, so it isn’t ideal for spotting small cavities or early tartar buildup between teeth.

On the other hand, bitewing X-rays are limited in scope—they typically capture just one to three teeth at a time. While they can sometimes show the very top portion of the supporting bone, they don’t provide a full view of deeper bone structures or extend far enough back to evaluate the jaw joints.
