Dentists use computed tomography (CT) scans to capture 3D dental X-rays of your teeth, jaws, joints, nerves and sinuses. These X-rays can also detect tumors or facial fractures. Surgeons often use dental CT scans to check the height, width and location of your jawbone before dental implant placement.

There are two main types of dental X-rays: intraoral (the x-ray film is inside the mouth) and extraoral (the x-ray film is outside the mouth). Intraoral x-rays are the most common type of X-ray.

Stand behind a shield or at least six feet from the X-‐ray source, and out of the path of the primary beam. Give warning before pressing exposure button to protect co-‐workers and patients. Never hold a receptor for a patient.

Yes, children can receive dental X-rays when appropriate, but it is important to carefully control the radiation exposure.

Digital X-ray machines capture images quickly, offer easier processing, and provide higher image quality, while traditional X-ray machines require film processing, which takes longer.

The price of dental X-ray machines varies depending on the brand and type, generally ranging from several thousand to tens of thousands of dollars.
