We switched to digital radiography years ago. Here's the difference in radiation exposure, image quality, and clinical utility, and why it matters for your care.
When patients see the digital sensor go into their mouth instead of a film packet, they sometimes ask: is this the same thing? The short answer is no, it's significantly better.
Radiation: The Number That Matters
Digital X-rays use up to 90% less radiation than traditional film X-rays. A full-mouth series with digital radiography delivers less radiation than you'd receive from an hour of flying at altitude.
For context: a traditional full-mouth series delivered approximately 150 microsieverts of radiation. Digital delivers 15-30. Bitewing X-rays (the standard yearly update) go from 5 microsieverts on film to 0.5 on digital.
These are small numbers in absolute terms. But cumulative medical radiation is a legitimate concern, particularly for children and patients who need frequent imaging. Digital eliminates most of that concern.
Image Quality
Digital images are sharper, higher-contrast, and immediately available, no developing, no waiting. More importantly, they're diagnostic in ways film can't be.
We can magnify a specific area by 300%. We can adjust brightness and contrast to see through a dense filling and examine the tooth beneath. We can overlay two images from different dates and highlight changes. We can draw a line measuring the exact depth of a bone defect.
None of that is possible with film.
Speed and Workflow
The image appears on screen within seconds of the sensor leaving your mouth. We review it with you at chairside, you see exactly what we see, explained in real time. Film required development, then physical handling, then mounting, then a separate review session.
Digital images are stored securely in your electronic record and instantly transferable to specialists or insurance companies when needed.
The Clinical Difference
Better images catch more, earlier. Interproximal decay (cavities between teeth) that would have been missed or caught late on film is visible on digital at Stage 1 or 2, when a small filling is the treatment rather than a root canal or crown.
This isn't theoretical. We've caught decay on digital X-rays that we're confident would have been invisible on the same case with film. Earlier detection means smaller restorations, lower cost, and better long-term outcomes.
The switch was straightforward for us. Better for patients, better diagnostics, and less radiation. That's an easy decision.
