Dentistry is Digital
Dental scanners have evolved significantly over the past forty years. More recently, they have become widely used for clear aligner treatments. I first used a dental scanner over 15 years ago to produce milled crowns, such as Volkscrowns. Today, digital scanning supports the printing and manufacturing of crowns, veneers, and removable appliances, including dentures. Some modern scanners can now detect tooth decay in certain areas more effectively than traditional dental X-rays.
Your X-Rays Belong to You
Your dental X-rays are your property. They can be:
Stored securely at your dentist’s surgery
Saved online (with your consent)
Shared with other dental professionals for a second opinion
If in-person access to a dentist is difficult, having digital X-rays analysed by AI — and then reviewed by a qualified dentist remotely in the UK or abroad — can be a reasonable way to support a timely assessment of your oral health.
Digital Dental Photography at Home
Although mobile signals are not always reliable, modern smartphones have excellent cameras that continue to improve each year. Dental photographs taken with smartphones or simple oral cameras are digital, allowing them to be stored securely, shared easily, and used to monitor changes in oral health over time.
These images can be reviewed either in real time or later by dental professionals. They are automatically time-stamped, do not deteriorate with age, and are ideal for tracking oral health across months or years.
The cost of small oral cameras has fallen significantly, with many now costing less than an electric toothbrush while still providing clear, useful images. Already valuable in care homes, these devices could also be used safely in people’s own homes.

Understanding Dental X-Rays, Digital Technology and AI
When the Dentists Act was introduced in 1984, dental X-rays were taken using small chemical films that required processing solutions, could degrade over time, and produced limited image detail. Dental imaging has since changed dramatically.
Today, dental X-rays are fully digital. There is no chemical processing or waste, and images are available instantly in high resolution. Importantly, modern digital dental X-rays use around 20% of the radiation required in the 1980s. Because images are digital, they can be stored securely, shared easily, and used to monitor changes in oral health over time.
In fact, most people are exposed to more radiation during a flight abroad than from a dental X-ray. As AI-based assessment tools continue to improve, there is growing potential for trained dental nurses to take radiographs, with images securely assessed online when a dentist is not immediately available — subject to appropriate consent and safeguards.
Using Dental Data to Improve Care for the Future
The more information AI systems can learn from, the better and more accurate their assessments become. As digital dental X-rays and imaging tools continue to develop, both current and future AI technologies will improve in how they help identify problems earlier and more consistently.
Protecting personal data is essential. However, it may be possible to share dental images and digital records in a fully anonymised way, so that individuals cannot be identified. This kind of secure data sharing could help improve dental care for future generations, potentially reducing the amount of treatment needed by detecting problems earlier.
Any sharing of dental data must be fully compliant with UK GDPR guidelines, with strong safeguards in place to protect privacy. With the right controls, there is clear scope for using anonymised digital dental data safely and responsibly — for the benefit of patients today and generations to come.
AI and Digital Radiographs: What’s the Benefit?
Artificial intelligence (AI) is being used in dental radiology to help interpret digital X-ray images. Multiple recent studies in dental journals show that AI can:
Improve consistency and repeatability of interpretations across images, reducing the variation you get when different clinicians read the same X-ray. AI reduces subjective differences in how humans interpret radiographs. (PMC)
Enhance diagnostic accuracy for dental conditions such as caries (decay), bone loss, and other findings compared with unaided human assessment. (MDPI)
Provide rapid analysis that supports dentists, especially when reviewing large batches of images or screening for subtle problems. (JMIR)
For example, research has shown that when operators use AI software alongside their own clinical assessment, the accuracy and sensitivity for detecting issues such as decay and lesions increases compared with assessment alone. (MDPI)
Another study in dental radiology highlights that AI methods can provide objective and standardised analysis, which helps improve agreement between interpretations and reduces the inconsistency seen among individual dentists. (PMC)
These findings suggest that AI doesn’t replace a dentist, but helps ensure your radiographs are read more consistently and thoroughly than with human interpretation alone.
