Which X-rays do we take?
Panoramic X-ray: shows both jaws, all the teeth, the jaw joints and the lower part of the sinuses in a single image. We use it at the first examination, for implant and surgical planning, before orthodontic treatment and to see impacted teeth.
Intraoral (periapical) X-ray: shows one or a few teeth up close, down to the root tip. We use it during root canal treatment, to check for decay under a filling and to follow infection at the root tip.
When is a CT scan needed?
An X-ray is a two-dimensional image. When we need to see bone width, the distance to a nerve or the borders of a cyst in three dimensions, we ask for a CT scan (cone beam computed tomography). We do not have a CT scanner at the clinic; when one is needed we refer you to an imaging centre and then review the images with you. Not every implant or wisdom tooth needs a CT scan.
About radiation
The dose from dental X-rays is low. A panoramic X-ray roughly equals the natural background radiation we all receive over a few days, and an intraoral X-ray is lower still. Even so, we do not take X-rays that are not needed.
If you are pregnant or might be, tell us before the X-ray. We postpone X-rays that are not urgent until after the birth.
Bring your previous X-rays
If you have a panoramic X-ray or CT scan taken elsewhere, bring it to your appointment; a CD or digital file is fine. If it is recent and shows what we need, we do not take it again.
Your X-rays are reviewed during the examination by the dentist planning your treatment, and we show you the findings on screen.
