An OPG is performed standing in an OPG X-ray machine. You will be asked to bite gently on a small tab or place your chin on a small rest. The Radiographer will position you head and teeth in the ideal position before gently bracing your head in place. The X-ray equipment slowly rotates around your head during the scan. The scan is completed in 15 to 20 seconds.
You may be asked to remove jewellery, eyeglasses, and any metal objects that may obscure the images.
