From chairside to cyberspace: When everything is connected—understanding cyber risk in modern dental technologies—Part 5

The shift happened incrementally, one connected device, one cloud platform, one remote service agreement at a time. Many practices now rely on internet-connected scanners and imaging systems, cloud-based practice management and imaging software, remote vendor access for support and updates, digital communication with laboratories, insurers, and patients, and AI-enabled tools embedded within existing platforms. Each addition may seem manageable in isolation. Together, they fundamentally change where cyber risk enters the practice.

Cybersecurity is no longer limited to the front-desk computer or the server in the back room. It now affects whether clinicians can access imaging and records, whether appointments can proceed, whether billing and claims can be processed, whether patient data remains confidential, and whether patient trust is maintained. Cybersecurity has become an issue that affects operations, business continuity and, increasingly, patient care.

Cyber risks in dentistry are often invisible under normal operational conditions. They become visible only when something goes wrong. Networked devices and imaging systems are often treated as clinical equipment rather than computers. Yet many rely on operating systems and software that cannot be easily updated with security fixes, that run older software no longer supported by manufacturers or that ship with default security settings that are rarely reviewed.

Cloud services are widely misunderstood. While vendors may secure the infrastructure, practices remain responsible for user access management, password practices and authentication, access permissions and access monitoring—who accessed what and when. Cyber risk is then largely determined by the behaviour of the users.

“Cybersecurity has become an issue that affects operations, business continuity and, increasingly, patient care.”

Beyond what happens inside the practice, risk also enters through the people and organisations that connect to practice systems. Remote support and third-party integration are essential in modern dentistry, but they expand the practice’s digital boundary. Risk increases when vendors reuse the same support login credentials across multiple practices, remote access is enabled permanently rather than only when needed, practices cannot see when a vendor is logged in or responsibility for monitoring access is unclear.

The same applies to connected partners—laboratories, insurers, payment processors, marketing platforms and AI services. A practice does not need to be directly compromised to be affected; indirect exposure through a third party is now one of the most common paths for cyber incidents.

AI does not introduce entirely new categories of cyber risk. Instead, it amplifies existing ones. AI is increasingly embedded within imaging software, scheduling and patient communication tools, documentation and workflow automation, and decision support and analytics platforms.

Because AI operates behind the scenes, clinicians may not realise how much data is being accessed or moved, whether data is used for training or improvement, how automated decisions are initiated, or how quickly missed or incorrect flags, information sent to the wrong place or unintended sharing of patient data, can scale. AI accelerates processes, increases data movement and reduces human manual checks for errors. From a cybersecurity perspective, this means less time to notice problems and greater impact when they occur. In this sense, AI acts as a risk accelerator, not as an isolated threat.

Two principles that I think are especially important for practices to consider before adopting a digital technology are that, firstly, the digital tool should be selected according to the task to be achieved and, secondly, every technology decision requires evaluation of the associated privacy and cybersecurity implications. Digital technology adoption should begin with clarity. Rather than asking what technology should be purchased, the practice should consider what problem needs to be solved, what processes need to be improved or automated, and what data is involved in that task. Before introducing a new digital solution, practices need to understand what data will be accessed, created or transmitted, where that data will be transmitted and where it will be stored, who will have access, both inside and outside the practice, how updates and security changes will be handled, and what dependencies the practice will have on the technology—and what the impact of these will be if the system is unavailable. Cybersecurity should be part of adoption discussions from the outset, not an afterthought once systems are already in place.

Cyber incidents are often framed as data breaches. In day-to-day practice, however, the most immediate impact is often operational disruption rather than data exposure or loss. When systems are unavailable, imaging and records may be inaccessible, appointments may need to be postponed or cancelled, scheduling and billing may halt, staff stress increases under uncertainty and patient confidence can be shaken. Cyber incidents caused by attacks, outages or technical failures quickly become continuity of care issues.

Cyber resilience does not require clinicians to become cybersecurity specialists. It requires awareness, preparation and informed decision-making. Key elements of resilience include regular training for the entire dental team, clear understanding of digital dependencies, defined roles for decision-making during disruption, documented procedures for downtime and recovery, and regular cybersecurity reviews, rather than one-time checklists.

“Connectivity, automation and AI will continue to reshape clinical and operational workflows.”

The dental team plays a central role. Many cyber incidents begin with everyday actions such as clicking links or responding to emails that appear routine. Training empowers teams to recognise risk without fear or blame.

Connectivity, automation and AI will continue to reshape clinical and operational workflows. Cybersecurity is now part of patient safety, professional responsibility, practice resilience and long-term trust. When addressed early and openly, cybersecurity supports innovation rather than hindering it. The most resilient practices are those that understand the risks, dependencies and responsibilities that come with being connected, but those that understand the risks, dependencies and responsibilities that come with being connected.

When adopting digital dental technology, clinicians are rarely purchasing a stand-alone device. They are implementing a connected ecosystem that includes software platforms, cloud services, remote access and third-party integration. Cyber risk rarely exists in any one system. It most often appears at the connection points, where data moves between systems, access is shared or responsibility becomes unclear. Thoughtful digital technology adoption begins with understanding how a new tool connects to existing workflows, what data it accesses, who can access it and what happens if that connection is disrupted.

Before adoption

• What specific task or workflow problem are we trying to solve?
• What patient or practice data will this system access, create or transmit?
• Where will that data be transmitted, and where will it be stored?
• Who will have access to the system, both inside and outside the practice?
• Does this system rely on cloud services, remote access or third-party integration?
• What other systems will it connect to or depend on?
• Who will be responsible for security updates, access monitoring and access management?

After adoption

• Do we know which systems are connected and how they interact?
• Can we see when external vendors or service providers are accessing our systems?
• Have team members been trained on how this technology changes daily workflows?
• Do we have a plan if this system becomes unavailable, even temporarily?
• Have we reviewed whether vendor access and third-party integration are still necessary?
• Would we notice quickly if something went wrong?
