An image helps answer a question that cannot be settled by looking at the teeth alone. It may show roots, surrounding tissues or the position of an impacted tooth. It does not replace discussion and examination, and more images do not automatically mean better diagnosis.
Matching the test to the question
Depending on the indication, imaging may cover one tooth, a wider area or three dimensional anatomy. The scope should serve the planned care. A scan is not routine simply because it offers more detail for certain purposes.
Existing records are useful
Bring previous images or details of how to share them. They may help compare changes and reduce the need to repeat an examination. Usefulness depends on quality, coverage and clinical circumstances, not merely on having an image.
What to mention beforehand
Tell the team if you are or may be pregnant, and about difficulties that could affect taking the image. Preparation is explained for the selected method. Do not independently arrange a scan before your first consultation without a specific recommendation.
From image to decision
Findings are interpreted alongside symptoms and examination. Ask how the image affects the plan and whether another consultation is needed. A radiological finding does not always mean surgery is necessary, but it should be explained in the context of your health.
