Welcome to the Future: What 3-D Dental X-rays Mean for You

What if your dentist told you that dental X-rays can be done in a single sweep, expose you to less radiation than a roundtrip flight from Paris to Tokyo , and result in a complete, 3-D picture of your mouth in as little as a few seconds?

For anyone who has ever had a mouthful of bitewings, it’s a dream come true, thanks to a relatively new technology called “cone beam radiography”. If you’ve never heard of it, you could be missing out. Here’s the scoop on this revolutionary diagnostic tool and what it could mean for your oral health.



Unlike traditional X-rays, which require exposure for one flat image, cone beam radiography – also known as cone beam computed tomography, or “CBCT” – can yield hundreds of images from just a single scan. Rather than having a beam pointed to a specific area of the mouth, a machine rotates around the patient (similar to CT scanners used in the medical field), capturing panoramic images of the mouth using a cone-shaped beam.



As with traditional dental X-rays , CBCT scans will only be recommended when necessary, and there are standard procedures in place to minimize your exposure to radiation.



The richness, clarity and accuracy of data that cone beam radiography provides can make a world of difference to the nature and effectiveness of your dental treatment. While 2-D X-rays provide ample information for standard practices such as detecting and treating cavities , the depth and conclusiveness of CBCT-derived data can point to the optimal approach for more complex matters such as:

In general, many dentists also find CBCT scans to be much more effective in diagnosing tooth pain than 2D X-rays. Getting the diagnosis correct the first time can save patients from unnecessary cost and health complications down the road.



Speak with your dentist to find out whether a CBCT scan makes sense for you. Depending on your unique dental needs and the amount of documentation your dentist already has, he or she can advise if cone beam radiography is necessary. If CBCT scans are not available at your dentist’s office, a medical CT scan by your local hospital or clinic may be recommended.
