Why dental X-rays are useful
Images can help identify decay between teeth, assess the root area and supporting bone, and investigate symptoms. They are interpreted alongside an examination and medical history, rather than replacing them.
Types of images
The original site describes intraoral images and panoramic views, with three-dimensional imaging discussed for selected planning needs. The clinician chooses an appropriate image for the question being investigated and current equipment availability.
Safety and preparation
Tell the team about pregnancy or possible pregnancy, relevant medical history and recent dental imaging. The clinician considers whether an image is necessary and uses appropriate exposure practices. Follow the operator’s instructions during the image.
The imaging visit
The operator positions the sensor or equipment and asks you to remain still for the exposure. Preparation is usually limited but depends on the type of image. The clinician reviews the findings and explains their role in your care plan.
YOUR QUESTIONS, EXPLAINED
Before your visit.
Do I need an X-ray at every visit?
No. Imaging frequency depends on the clinical findings, risk and the information needed.
Can dental X-rays be harmful?
X-rays use ionising radiation. Dental professionals balance the diagnostic benefit with exposure and select images only when appropriate.
What happens at my consultation?
Bring your medical history, current medicines and any previous dental records. The clinician examines your mouth and recommends tests or imaging when needed. You can discuss the proposed care, alternatives, timing, costs and follow-up before making a decision.
Care in focus.

Make an informed choice.
Use this guide to prepare questions for a dental consultation. Your diagnosis, treatment suitability, number of visits and estimate depend on an individual examination. Tell the team about previous treatment, medical conditions and any concerns about comfort.
