Patient Information

OPG Scan

An Orthopantomogram (OPG) scan is a specialised dental X-ray that provides a panoramic image of your teeth, jaw, and surrounding structures in a single scan.

​

Unlike small dental X-rays that show only a few teeth at a time, an OPG captures a wide view of the entire mouth, including the upper and lower jaws, tooth roots, jaw joints, and sinuses. OPG scans are commonly used by dentists, orthodontists, and oral surgeons to assess dental development, diagnose jaw conditions, and plan treatments such as orthodontics, wisdom tooth removal, or dental implants.

​

The scan is quick, painless, and uses a very low dose of radiation, making it a safe and efficient way to evaluate oral and jaw health.
