Better diagnosis: The dentist uses x-rays to detect decay between the teeth and to see how deep decay is in a tooth. Also, the dentist can see changes in the bone structure surrounding the teeth.

Visualization: Dental x-rays are used to allow the visualization of cavities, bone level, tumors and infections causing bone loss in areas that cannot be seen directly by the eye. They can be used to determine the presence of unerupted teeth as well as malpositioned teeth. Specific x-rays may show the adequacy of one's airway space.

To see: Like a physician can see a broken bone with an x-ray when they cannot see it from the outside of your body, the dentist uses an x-ray to see the condition of the interior of the tooth and bone. However, an x-ray does not tell the entire story, it is only one step of great assistance in diagnosis and treatment.

Comprehensive Care: Dental x-rays are part of the comprehensive approach to proper dental health. They are used in conjunction with a visual exam (clinical), as well as intraoral camera pictures (photos), etc to give the doctor and the patient an entire series of information, ensuring proper care is given. We see additional information from x-rays that we would otherwise not see.

Showing the unseen: X-radiation is absorbed at different rates by the materials through which they pass, and can be detected with film or digital sensors. The rays pass through bone and teeth and cast a shadow of what is covered or concealed allowing dentists to diagnose the presence of treatment needs. The position of unerrupted teeth and the presence of decay and many other anatomical features can be discovered.

Dental x-rays: A diagnostic adjunct. They allow us to see places not visible to the naked eye such as between teeth, within the teeth, under the gums, architecture and health of tooth=supporting bone, jaw relationships, development of as yet unerupted teeth, and so many other structures. They allow us to fill in the blanks. To diagnose we need a full knowledge base.
