Frequently Asked Questions

Dental X-Rays

  • Why do you need regular dental x-rays?

    Tooth decay can be sneaky – it doesn’t tend to show physical signs of its presence or pain early on.

    When your dentists perform an examination, they are limited to what they can see in your mouth – they can only see the part of the tooth that sits above the gum. Even then, dentists cannot see clearly between teeth where they touch.

    X-rays help the dentist find and treat dental problems early in their progress, which can potentially save you money, unnecessary discomfort, and pain. So just like other x-rays ordered by medical doctors to check for things like broken bones, dentists use dental x-rays to help see inside your teeth and the parts that sit below the gums and in the surrounding bone.

  • What Problems Can Dental X-Rays Detect?

    Decay that may not be visible with a standard exam, especially small areas of decay between teeth

    Identify decay occurring under an existing filling

    Reveal an abscess from an infected tooth

    For adults
    • Reveal bone loss that accompanies gum disease
    • Reveal changes in the bone or in the root canal resulting from infection
    • Assist in the preparation of tooth implants, braces, dentures, or other dental procedures
    For children
    • Determine if there is enough space in the mouth to fit all incoming teeth
    • Determine if primary teeth are being lost quickly enough to allow permanent teeth to come in properly
    • Check for the development of wisdom teeth and identify if the teeth are impacted
  • How Often Should Teeth Be X-Rayed?

    The frequency of getting X-rays of your teeth often depends on your medical and dental history and current condition. Some people may need X-rays as often as every six months; others with no recent dental or gum disease and who visit their dentist regularly may get X-rays only every couple of years

  • Are X-Rays safe?

    Regardless of whether you’re a child or an adult, you can have dental X-rays safely taken inside and outside of your mouth. The amount of radiation involved is extremely low, and is equivalent to the sort of exposure you’d receive on a 1-2 hour flight. This means that even if you’re pregnant you can have X-rays taken, although they are generally kept to a minimum during this period.
    So why does your dentist leaving the room while the X-rays are taken?
    Nothing to worry about there – they’re taking lots of X-rays all day long and stepping out of the room limits their ongoing exposure to radiation.
