Why an X-ray?
X-rays show decay between teeth, infection at the root tip, the shape of the root canals, and adult teeth growing under milk teeth. For a root canal, they guide the treatment at each step.
Is it needed every time?
No. The dentist decides from your symptoms and examination. If you have recent X-rays from another clinic, bring them along.
Digital imaging
Digital sensors produce the image in seconds on screen, so the dentist can show you what they see. A lead apron is used for protection.
How much radiation?
The radiation from a dental X-ray is very small, and digital sensors generally need less than older film. The dentist takes only the images that help answer a question, and uses a protective apron. If you are or may be pregnant, tell the dentist before any X-ray is taken.
For children
The sensor is small, and a child can hold a parent’s hand. Tell the clinic if your child finds it hard to keep still.
