OPG in Dentistry: What to Expect from a Dental Panoramic X-Ray

OPG, or Orthopantomogram, is a special dental x-ray. It shows a wide view of your mouth in one image. Dentists use OPG to check teeth, jaws, and nearby bones. This scan helps spot problems early. Because of this, OPG is important for good dental care.

What is an OPG?

An OPG is a dental panoramic x-ray. It captures your entire mouth in a single picture. Unlike small x-rays, OPG shows all teeth, both jaws, and jaw joints. This makes it easier for dentists to see the big picture. For example, they can spot hidden issues quickly.

Why is an OPG Done?

Often, dentists suggest an OPG for many reasons. Here are some common uses:

To check for tooth decay or gum disease

To find wisdom teeth or extra teeth

To plan braces or other dental treatments

To look for jaw problems or injuries

To spot cysts, tumors, or infections

Because it gives a full view, OPG helps dentists make better decisions.

How is an OPG Performed?

Getting an OPG is simple and quick. First, you stand or sit in front of the x-ray machine. Next, you bite gently on a small plastic piece. The machine moves around your head. It takes a picture in less than a minute. You do not feel any pain during the scan.

Benefits of OPG in Dentistry

OPG offers many benefits for dental care. Some key advantages include:

Shows all teeth and jaws in one image

Helps find hidden dental problems

Quick and easy procedure

Low radiation compared to some other scans

Useful for planning treatments like braces or implants

Because of these benefits, OPG is a common tool in modern dental clinics.

Risks and Safety of OPG

OPG uses a small amount of x-ray radiation. However, the dose is very low and safe for most people. According to the World Health Organization, dental x-rays are safe when used properly. Still, pregnant women should tell their dentist before any x-ray. Dentists use lead aprons to protect you during the scan.

How to Prepare for an OPG

Usually, you do not need special steps before an OPG. But, you should:

Remove jewelry, glasses, or metal objects from your head and neck

Tell your dentist if you are pregnant

Follow any instructions from your dental team

Because the scan is quick, you can return to normal activities right after.

What to Expect During and After the Procedure

During the OPG scan, you will stand or sit still. The machine will move around your head. You may hear a soft whirring sound. The scan takes less than a minute. Afterward, you can go home or back to work. Your dentist will review the images and discuss the results with you.
