Dental X Rays OPG

About Dental X Rays OPG:
Dental X-Rays in Chatswood, also known as OPG scans, provide a panoramic view of the lower face in a single image. This wide scan shows all the teeth in both the upper and lower jaws, including those that haven’t yet erupted, such as wisdom teeth.
An OPG X-ray also allows dentists to assess the jawbone and the temporomandibular joint (TMJ), which connects the jaw to the skull. This makes it an important tool for diagnosing dental issues, planning treatments, and monitoring overall oral health.
At our Chatswood dental clinic, we use modern OPG technology to ensure accurate, safe, and detailed imaging for effective dental care.
Advantage of Dental X Rays OPG:

- Low patient radiation dose.

General FAQs
A dental OPG X-ray (Orthopantomogram) is a single panoramic X-ray that captures a wide view of your entire mouth. Unlike smaller X-rays that focus on individual teeth, an OPG shows all teeth, upper and lower jaws, and surrounding structures in one image, helping dentists detect issues and plan treatments effectively.
Yes, panoramic X-rays are safe. Modern digital X-rays use very low radiation, often less than natural background exposure over a few days. Dentists follow strict safety guidelines, including protective measures, and only take X-rays when necessary. Pregnant women should inform their dentist, as the X-ray may be postponed unless urgent.
A dental OPG X-ray is usually recommended about every 5 years for general screening. Your dentist may suggest more frequent X-rays depending on your oral health history, such as cavities, gum disease, or if planning orthodontic treatment or dental implants. The frequency is determined based on your individual needs.
A dental OPG X-ray can reveal issues with teeth, jawbones, and surrounding structures, including cavities, impacted wisdom teeth, cysts, tumors, and bone loss. It provides a panoramic view of the entire mouth, showing tooth positions and growth, and helps assess jaw health, the temporomandibular joint (TMJ), and sinuses for accurate diagnosis and treatment planning.
No special preparation is needed for a dental X-ray. Brush your teeth beforehand for hygiene, and remove jewelry, eyeglasses, or metal objects that may interfere with the image. Bring your referral and Medicare card if applicable.
