Dental X-rays are 2D images that highlight the bones and tooth anatomy in your mouth below the surface of your gums and enamel. There are two types of dental X-rays: film and digital. Digital is replacing film, as it has done in many other technologies, as it emits approximately 80% less radiation than film X-rays, is a quicker process, and is easy to archive. Because of these major benefits, all 123Dentist practices use digital X-rays exclusively.
Dental X-rays can either be intraoral X-rays, which involve taking the X-ray image from inside the mouth, or extraoral X-rays, which are taken outside of the mouth, generally around the jaw area. Intraoral X-rays show fine details in the teeth and their supporting bones that allow your dentist to identify cavities, tooth development, root health, and the tooth’s anchoring to the jaw bone. Extraoral X-rays focus more on the larger structural bones of your head, specifically your upper and lower jaw. These images help dentists identify issues such as impacted teeth, monitor jaw joint health and development, and see fractures or breaks clearly.
