Computer Digital Radiography (CDR)

Dental x-rays can now be taken using sensors that transmit the image directly into a computer monitor. This larger image helps the patient understand the doctor's explanations more easily and enables the doctor to "zoom in" on a specific area of the tooth. An important advantage to this new technology is that it reduces the amount of radiation by 90%. Digital x-rays are also faster. The digital image only takes 20 seconds to appear in the monitor. In addition, this new technology is friendly to the environment since no chemicals are needed for developing the image.

What are Dental X-rays?

What most people call X-rays are actually X-ray photographs (also known as radiographs). An image is made using X-rays, which are similar to sunlight, but of a shorter wavelength, and able to show us what's below the surface of a tooth. Even though we call them X-rays, we are actually referring to the image created by X-rays.

Why are Dental X-rays Necessary?

X-rays are the only way to identify problems that aren't externally visible. X-rays are very essential in doing a complete and thorough dental examination. They are especially important in diagnosing serious conditions early to allow for effective treatment before you experience discomfort. X-rays show bone anatomy and density, decay between the teeth or how extensive the decay is, whether an abscess is present, impacted teeth, or if children have permanent teeth.

No cavity on first x-ray.	Months later, cavities that start between the teeth can't be seen by visual examination, but they can be detected on an x-ray.

This cavity was detected and filled before the patient felt any discomfort, and before the nerve became infected or the tooth became abscessed.

There is another cavity shown in the X-ray on the right. Can you find it? It's difficult for the untrained eye to spot. Click here to see where it is. (Hint: It's not the left edge of the top left tooth. That's just the edge of the frame around the X-ray).

How Often Do I Need Dental X-rays?

The number and type of X-rays you will need depends on several factors such as age, current dental health, and external signs that may trigger a cause for concern. We are sensitive, however, to your concerns about exposure to radiation, and we only perform those X-ray procedures that are necessary for your continued dental health.
