Diagnostic X-Rays

When your child comes in for a routine cleaning or exam, we want to be as thorough as possible and catch any issues before they become problematic. This includes examining the gums, bone structure and developing teeth. X-rays allow us to check under the gums and inside the teeth. They can also help us to see cavities forming between teeth, which is not visible to our naked eyes.

While x-rays provide valuable insight into your child’s dental health, we also understand your concern about the radiation your child receives during the x-ray. We are committed to making every procedure at our office as safe as possible and encourage you to read the following information to learn more.

The AAPD is a member of the Alliance for Radiation Safety in Pediatric Imaging — the Image Gently Alliance. Our office supports the standards and recommendations put forth by the Alliance. We wish to optimize the radiation dose used in dental imaging exams performed on children through the following guidelines and standard practices:

  • Select X-rays for individual needs, not as a routine. Use X-rays only when essential for diagnosis and treatment — based on a review of the patient and their dental history.
  • Always use a thyroid shield. The thyroid gland in children is particularly sensitive to radiation. Use of a properly positioned shield significantly reduces the dose to the thyroid.
  • Child-size the exposure time. Less exposure time is needed for children as oral structures are smaller than in adults.
  • Digital x-rays - First and foremost, digital radiography reduces patient’s exposure to radiation—usually 70 to 80 percent.  Many patients are very relieved that digital radiology significantly lowers the amount of radiation they will receive.


We understand that parents can feel apprehensive about exposing their child to radiation during dental x-rays and we want to help alleviate your concerns. Most of the fear about x-rays lies in not knowing just how much radiation your child will be exposed to. We offer this comparison to hopefully ease any concerns our patients might have. Feel free to ask as many questions as you would like.
