Dental x-rays can be used for both preventive and diagnostic procedures. In preventive dentistry, x-ray allow dentists to view the individual teeth, roots, sockets, surrounding tissue, and jawbone. Cracks, cavities, or other abnormalities in the teeth can be identified at an early stage. Diagnostic x-rays can be used to check the extent of any tooth decay, problems with jawbones, and the condition of teeth that have not yet erupted, such as wisdom teeth.

Are x-rays safe?

Dental x-rays are safe. The dosage emitted by a dental x-ray machine is very low, only equivalent to the radiation that you would be exposed to in a few days outdoors. According to the NHS, the chance of getting cancer from dental x-rays is less than 1 in 1,000,000 chance of getting cancer from dental x-rays.
