X-rays can show decay that may not be seen directly in the mouth: for example, under a filling, or between the teeth. They can show whether you have an infection in the root of your tooth and how severe the infection is.
In children an x-ray can show any teeth that haven’t come through yet, and show the dental team whether there is enough space for the teeth to come through. In adults, it can show any impacted wisdom teeth that may need to be removed, before they cause any problems.
