Dental X-Rays

They can also create a record of current oral health, so later images can help identify changes over time.

A new patient may need images to document current oral health and create a baseline. Children and teenagers may need them more often because their teeth and jaws are still developing.

For each image, the dental team positions you and focuses the beam on the area that needs to be examined.

Dental X-rays use very low radiation doses. Imaging tools and techniques are designed to limit exposure, and images are used in moderation to reduce radiation further.

For children, intraoral radiographs are the standard diagnostic tool. Cone beam CT needs specific justification and comprehensive interpretation because of its safety considerations.

An image can act as a baseline for later comparison, but an X-ray is not automatically needed at every dental visit. The timing depends on the diagnostic information required.

The image is selected to answer a particular diagnostic question. You are positioned for the X-ray, then the beam is directed at the area of interest to obtain the image.

The image can confirm that teeth are healthy or show disease or damage that was not visible during the examination. Its value continues when it is compared with later changes in oral health.

Previous images may be forwarded to a new dental practice instead of making another set. When a new image is needed, the type is selected to provide the diagnostic information required.

The decision to take an X-ray considers current oral health, age, disease risk, and signs or symptoms of oral disease. Clinical findings and dental history also guide the timing and selection of images.

Dental X-rays are taken when they provide the information needed to assess oral health, identify a problem, or guide treatment planning.
