Why might the dentist recommend X-rays?

Hi, I'm Sam, a dental hygienist.

Why might the dentist recommend X-rays?

A dental X-ray is a picture that shows what is happening inside your teeth and under your gums. It reveals problems that are not visible during a regular exam, like cavities forming between teeth or issues with tooth roots. X-rays can also show the extent of gum disease, bone loss in the jaw, and impacted teeth.

The need for dental X-rays is different for everyone, so you may not need them at every visit. Your dentist determines if they are necessary after reviewing your health history and examining your mouth. Your personal risk for oral disease and any symptoms you may have also help determine the timing. Children and teens might need them more often because their teeth and jaws are still developing.

For a new patient, a dentist may recommend X-rays to establish a baseline of your current oral health. This helps in monitoring changes over time. If you have recent X-rays from a previous dentist, it may be possible to use those copies instead of taking new ones.

Dental X-rays involve a low amount of radiation exposure. While the diagnostic radiation risk is very small, it is never described as zero. The team works to keep the exposure no higher than necessary to get the information needed. Some offices use a lead apron for shielding, but this practice varies by location and regulations.

You can ask the dentist why an X-ray is recommended for you at a particular visit. It is also helpful to understand how the images will guide decisions about your care.

Call the office if you have questions about your visit or your care. This is general information, not personal instructions. Your own care team can tell you what applies to you.

Thanks for watching.
