A panoramic dental X-ray (OPG) is a specialized two-dimensional image that captures a wide view of your entire mouth. Unlike small intraoral X-rays that focus on one or two teeth, this single scan includes the upper and lower jaws, all the teeth, surrounding bone structures, the nasal area, and the temporomandibular joints (TMJ). This comprehensive image is useful for evaluating impacted wisdom teeth, assessing jaw abnormalities, planning orthodontic treatment, or preparing for dental implants.
Types of Providers Who Offer Panoramic X-rays
The most common place to receive a panoramic X-ray is within a general dentistry office, provided the practice is equipped with the specialized machine. Many modern general dentists have the equipment on-site for patient convenience, allowing the image to be taken immediately following a recommendation. It is best to first inquire if your primary dental provider offers this service, as it streamlines the diagnostic process.
Specialized dental professionals also routinely utilize OPGs. Orthodontists use them extensively to assess tooth development and position before beginning treatment. Oral surgeons and periodontists require these images to evaluate bone density, check for cysts or tumors, and plan complex procedures like extractions or implant placement. These specialized offices are highly likely to have the panoramic imaging technology readily available.
If your dentist or specialist does not have the equipment, they will provide a referral to a dedicated dental imaging center or a dental radiology group. These centers focus solely on advanced diagnostic imaging, including OPGs and sometimes more detailed Cone-Beam Computed Tomography (CBCT) scans. Less frequently, the service may be available at hospital outpatient diagnostic departments. Imaging centers are often the preferred alternative for a referral, as they can quickly process the X-ray and send the digital results back to your referring dentist.
What to Expect During the Imaging Process
The panoramic X-ray procedure is quick and non-invasive, taking place outside of the mouth. Before the scan, you must remove any metal objects from the head and neck area, including jewelry, hairpins, and glasses, as these interfere with image quality. You will also be provided with a lead apron to protect the rest of your body from radiation exposure.
The technician will position you to stand or sit stationary in the center of the machine, with your head placed against a support and your chin aligned. A small bite-block is often used to ensure proper alignment of the teeth and jaw. Once positioned, the X-ray tube and the sensor will rotate in a semi-circle around your head, starting on one side of your jaw and finishing on the other.
The actual scan time is very brief, usually lasting between 12 and 20 seconds. The process is painless, requiring only that you remain still for the short duration of the rotation. Modern digital panoramic machines use a very low dose of ionizing radiation, which is considered safe for most patients. The resulting digital image is usually available for the dentist’s review almost immediately.
Financial and Referral Considerations
Insurance coverage for panoramic X-rays varies significantly based on your specific dental plan. Many policies categorize the OPG as a routine diagnostic tool and will cover the cost, though they often impose frequency limitations. Coverage may be limited to one panoramic X-ray every three to five years, rather than annually like traditional bitewing X-rays. You should contact your insurance provider beforehand to confirm your specific coverage and frequency limits.
For individuals without dental insurance, the out-of-pocket cost for a panoramic X-ray typically falls between $100 and $250. It is advisable to call the dental office or imaging center in advance to get a specific quote, as prices fluctuate based on location and provider. Some facilities offer cash discounts or in-house dental membership plans that can reduce the cost.
A referral from a general dentist or specialist is nearly always necessary to obtain a panoramic X-ray, particularly when using a separate imaging center. The referral ensures the imaging center knows exactly what views the referring provider requires for diagnosis and treatment planning. To avoid unexpected expenses, confirm with the imaging facility that they accept your insurance and that any necessary pre-authorization has been secured before your appointment.
