CBCT scans in endodontics: seeing your tooth in 3D

What is a CBCT scan?

A cone beam CT scan is a 3D X-ray.  Where an ordinary dental X-ray is flat and in 2D, a CBCT builds a three-dimensional picture of your tooth, its roots and the surrounding bone, which we can look through together slice by slice.

Why a 3D view helps

Roots are narrow, curved and often hide extra canals.  Seeing those roots in three dimensions helps me find canals a flat image can miss, judge the extent of any infection, and spot cracks or unusual anatomy before we begin.

The same upper front tooth on a conventional X-ray and on a CBCT scan.  The flat image gives no sense of how large the infection is or how far the infection spreads; the 3D scan shows its height, width and depth, and how close the infection sits to the surrounding structures.

Especially useful for difficult cases

For re-treatments, calcified or hard-to-find canals, and teeth that haven’t settled after previous treatment, a 3D scan often makes the difference between a confident plan and guesswork.

Is a CBCT scan safe?

A CBCT uses a low dose of radiation, focused on the small area of interest, and I only take one when the information the scan gives will genuinely improve your treatment.  The benefit to your care is always weighed against that small exposure, in line with current guidelines.

What a CBCT scan is like

The scan is quick and entirely comfortable.  You simply stay still for a few seconds while the scanner moves around your head - no injection, and nothing touching the tooth.

The difference a 3D scan makes

Not every tooth needs a 3D scan, but when a scan helps, the extra detail lets me treat with far more certainty and preserve as much of your natural tooth as possible.
