How do dental X-rays work? When X-rays pass through your mouth during a dental exam, more X-rays are absorbed by the denser parts (such as teeth and bone) than by soft tissues (such as cheeks and gums) before striking the film. This creates an image called a radiograph. Teeth appear lighter because fewer X-rays penetrate to reach the film. Tooth decay, infections and signs of gum disease, including changes in the bone and ligaments holding teeth in place, appear darker because of more X-ray penetration. Dental restorations (fillings, crowns) may appear lighter or darker, depending on the type of material used for the restoration. The interpretation of these radiographs allows the dentist to safely and accurately detect hidden abnormalities. Return to Top How often should radiographs be taken? How often X-rays (radiographs) should be taken depends on the patient’s individual health needs.
