Dental radiographs, commonly called x-rays, help dentists examine areas that cannot always be seen directly. They may be used to evaluate disease, dental development, healing, or the progress of treatment, depending on the clinical question.
There is no single x-ray schedule that is right for every person. The dentist considers the examination, current symptoms, oral and medical history, prior images, age, development, and risk for oral disease before deciding whether new images are expected to affect care.
Why an X-Ray May Be Recommended
An examination shows the surfaces and tissues the dentist can see or feel directly. An x-ray adds a different kind of information. Depending on the image, it may help evaluate areas between teeth, bone around the teeth, tooth roots, developing teeth, or a specific area connected with pain, swelling, trauma, or prior treatment.
The image should answer a clinical question. FDA and dental guidance advises clinicians to order radiographs when the added diagnostic information is expected to affect patient care, not simply as screening before the health history and examination are considered.
Why Timing Differs From Patient to Patient
- A new symptom, visible finding, or history of trauma may make an image useful sooner.
- A patient’s risk for tooth decay or periodontal disease can affect the recommended interval.
- Children and adolescents may need images that help assess growth and dental development.
- Useful prior images may reduce the need to repeat the same view.
- Different clinical questions require different types and numbers of images.
Ask what the recommended image is intended to show and whether the office has received recent images from another provider. Sharing prior records does not guarantee that no new image is needed, but it gives the dentist more information for the decision.
Balancing Information and Exposure
X-rays use ionizing radiation. Once an image is justified, the dental team uses equipment and techniques intended to obtain diagnostically useful information while keeping exposure as low as reasonably achievable. The appropriate settings depend on the patient and the type of image.
Tell the team if you are or may be pregnant, if another office recently took dental images, or if you have questions about the recommendation. The dentist can explain the anticipated benefit, the image being requested, and how it fits into the examination or treatment plan.
