Pediatric Dental Radiographs (X-Rays)

Dental radiographs, commonly known as dental X-rays, are important diagnostic tools in pediatric dentistry. They allow dentists to detect and treat issues such as cavities, tooth decay, orthodontic misalignment, bone injuries, and bone diseases—problems that may not be visible during a routine clinical exam.

The American Academy of Pediatric Dentistry (AAPD) approves the use of dental X-rays in children and teenagers. Although X-rays emit very low amounts of radiation, they are used judiciously to minimize exposure while providing important diagnostic information.

Uses of Dental X-Rays

  • Assess available space for incoming permanent teeth.
  • Check whether primary teeth are shedding properly for adult teeth to emerge.
  • Evaluate the progression of bone disease.
  • Monitor and diagnose tooth decay.
  • Plan treatment, especially orthodontic treatment.
  • Detect bone injuries, abscesses, and tumors.
  • Identify impacted wisdom teeth.

When Are X-Rays Needed?

The frequency of dental X-rays depends on individual risk factors:

  • Children at higher risk for tooth decay may need X-rays every 6 months.
  • Children at risk for orthodontic issues may require more frequent X-rays for monitoring.
  • Children at average or low risk should have X-rays taken every 1–2 years.
  • X-rays may be taken immediately after trauma or injury to assess damage.

Modern X-ray technology allows dentists to target specific areas of the mouth, reducing unnecessary exposure.

Safety Precautions

Pediatric dentists take several measures to ensure the safety of children during X-rays:

  • Use of a lead apron to shield the body from unnecessary radiation.
  • Shields to protect parts of the face not being X-rayed.
  • High-speed film to minimize radiation exposure.

If you have questions or concerns about dental radiographs for your child, contact your pediatric dentist for guidance.
