Dental X-Ray

A Dental X-Ray is an image of the teeth and the jaw taken on a film by means of an electromagnetic radiation.

Structures that are dense (such as silver fillings or metal restoration) will block most of the photons and will appear white on developed film. Structures containing air will be black on film, and teeth, tissue, and fluid will appear as shades of gray.

How the Test is Performed

Best Dental Clinic uses digital technology to take X-Rays where the image runs through a computer. The amount of radiation transmitted during the procedure is less than traditional methods.

Dental x-rays may be used to identify the following:

  • The number, size, and position of teeth
  • Unemerged or impacted teeth
  • The presence and extent of dental caries (cavities)
  • Bone damage (such as from periodontitis)
  • Abscessed teeth
  • Fractured jaw
  • Malocclusion of teeth
  • Other abnormalities of the teeth and jaw bones


There is very low radiation exposure. However, no one should receive more radiation than necessary. A lead apron can be used to cover the body and reduce radiation exposure, especially for pregnant women.
