Deciding which images you need

Your dentist decides whether you need X-rays and which kind, based on your current oral health, age, risk for disease and any symptoms. There is no one-size-fits-all schedule, and you can talk it over with your dentist.

Steps in a typical case

  1. Deciding which images you need

    Your dentist decides whether you need X-rays and which kind, based on your current oral health, age, risk for disease and any symptoms. There is no one-size-fits-all schedule, and you can talk it over with your dentist.

  2. Getting into position

    You sit or stand in front of the machine while the technician positions the film or sensor and takes the image. Stay as still as possible.

  3. Images from inside the mouth

    For these, the film or sensor goes inside your mouth. Bitewing images show cavities between teeth and below the gumline. Periapical images show gum disease, bone loss and cavities near the tooth roots.

  4. Panoramic image

    A panoramic X-ray is taken with the sensor outside your mouth. It shows your entire mouth, including your teeth, jaws, nerves, sinuses and bone.

  5. Looking at the images

    Your dentist uses the images to look for cavities, decay under existing fillings, bone loss, impacted teeth and infections. They also help plan treatments like implants, braces or dentures, and track healing.

  6. Keeping exposure low

    Dental X-rays use a very low amount of radiation. Digital X-rays use 80% to 90% less radiation than film. Dentists also limit the X-ray beam to the area that needs to be examined and try to use images from earlier exams.

Questions to ask your dentist

  • The typical case takes one visit. Would mine, and how long would it take?
  • What are my other options, including waiting, and what happens if I wait?
  • How long does it usually last in a case like mine, and what upkeep will it need?
  • Will it hurt, and what can I eat or do while it heals?
  • What will it cost me, and will my insurance cover it? Ask which billing codes apply (the typical case uses D0210, D0274, D0330).
  • How many of these have you done, and who would do mine?
