Dental X-Rays

Dental X-rays (also called radiographs) are a diagnostic tool used by dentists to view the internal structures of the teeth, jawbone, and surrounding tissues. They help identify problems that are not visible during a routine dental examination, such as tooth decay, bone loss, abscesses, and impacted teeth. Dental X-rays are an essential part of preventive and therapeutic dental care.

Importance of Dental X-Rays

  • Detect cavities between teeth and under fillings.

  • Identify bone loss from periodontal (gum) disease.

  • Locate infections, abscesses, or cysts.

  • Assess the development of wisdom teeth or other unerupted teeth.

  • Monitor the progress of orthodontic treatment.

  • Diagnose tumors or other abnormalities.
