A dental X-ray is a type of imaging test that helps dentists see the inside of your teeth and jaw. It uses a small amount of radiation to create pictures of your teeth, gums, and surrounding bone. This allows dentists to detect issues like cavities, infections, or bone loss that may not be visible during a regular examination. Dental X-rays are typically quick and painless. Patients usually wear a lead apron for protection, and the process involves biting down on a small film or digital sensor. The images produced help in planning treatments and maintaining overall oral health.
