Your dentist will sometimes perform an X-ray during your check-up:

- X-rays can highlight cavities between teeth, assess damage to a tooth, help visualise the position of erupting wisdom teeth or identify jaw problems.
- The X-ray machine will be positioned by your side and sometimes spacers are placed inside your mouth to help obtain the image.
- It is perfectly normal for the operator to step outside of the room while the X-ray is taken.
