Dental X-ray

Dental X-ray of half of a mouth.

X-rays are a form of electromagnetic radiation. They strike an object and, depending on the density of the object, some of the x-rays will be absorbed. X-rays that aren’t absorbed pass through the item being x-rayed, and they hit a photographic plate to give an image.

X-rays are used by dentists to diagnose and treat a wide variety of problems.
