A dentist provides a thorough examination of the teeth and gums, looking for signs of decay and disease before cleaning teeth
Take a walk down the spectrum of electromagnetic radiation—past the radio waves on your FM dial, past the microwaves in your kitchen, past the visible light waves all around you—and eventually you’ll come to x-ray waves. Although they’re best known for helping superheroes tell which cereal boxes have the best toys, when directed at a special film or digital sensor these rays give dentists insight into the hidden features and spaces in their patients’ mouths.
As the x-ray waves travel, they must first pass through objects—in this case, a series of soft tissues, such as gums, and dense bone, namely teeth. The rays pass easily through softer tissue, but the denser material absorbs the rays before they reach the film, causing them to appear as bright, conspicuous walls of white on the final exposure. In most cases, dentists use bite-wing x-rays to capture a detailed view of teeth from gums to crown; placed directly in the mouth, the film or sensor provides a close-up view of every crevice and cavity. The resulting image—called a radiograph—is one of dentists’ most valuable diagnostic tools, allowing them to pinpoint areas of decay between teeth or under existing fillings, reveal potential issues in the root canal, or uncover any discrete abnormalities such as cysts. Dental x-rays emit very low levels of radiation—digital machines even less—but dentists nevertheless limit most patients to one session every one to three years.
