Dental imaging relies on X-radiation, a form of ionizing radiation, to visualize teeth and surrounding bone. X-ray photons penetrate soft tissues but are absorbed differently by dense structures like enamel and bone, creating a contrast image on film or a digital sensor. This contrast lets clinicians see tooth shape, decay, fractures, bone levels, and other pathologies that aren’t visible in a routine exam.

Ultrasound uses sound waves and isn’t effective for imaging hard dental tissues, so it isn’t used for standard dental radiographs. Magnetic resonance uses magnetic fields and radiofrequency energy to image mainly soft tissues and does not involve ionizing radiation, making it unsuitable for routine dental X-ray imaging. Using radioactive substances involves nuclear imaging for functional information and isn’t used to capture the detailed morphology of teeth and supporting structures.
