Yes. Digital OPG machines use highly sensitive electronic sensors instead of chemical film. Because the sensors are so efficient at capturing x-ray photons, the machine emits up to 80% to 90% less radiation than older analog panoramic machines, making it incredibly safe for routine screening.
Yes. Dental pain is often a late-stage symptom. Many destructive conditions—such as jawbone cysts, benign tumors, severe bone loss from gum disease, and impacted wisdom teeth damaging neighboring roots—occur silently inside the bone with zero pain. An OPG is a crucial screening tool to catch these silent issues early.
An OPG is a 2D (flat) image of your entire mouth. It is excellent for general screening, checking for cavities, and viewing overall bone levels. A 3D CBCT (Cone Beam Computed Tomography) is a three-dimensional scan that allows the surgeon to rotate and slice the image digitally. CBCT is mandatory for high-risk procedures like placing dental implants or removing wisdom teeth resting directly on the facial nerve, as it shows exact depth and width.
