Dental X-rays are a vital part of a dental examination There are two main types of dental X-rays: those taken with the X-ray film inside the mouth (intraoral) and those taken with the X-ray film outside the mouth (extraoral). Intraoral X-rays are the ones most commonly used. They provide detailed evidence of the growth of developing teeth, the health of tooth roots and surrounding bone, including the jaw. They also help the dentist zero in on any cavities. Extraoral X-rays, while they also show the teeth, primarily focus on the jaw and skull. They are therefore more helpful in diagnosing malocclusions, impacted teeth, and possible temporomandibular joint disorders (TMD).
