Within dentistry, what once involved a small number of independent systems now increasingly relies on continuous connectivity between devices, software platforms, vendors, cloud services, laboratories, insurers and increasingly, artificial intelligence (AI) services. In many practices, scanners transmit data to imaging software, imaging software syncs to the cloud, the cloud connects to third parties and remote service providers can log in at any time. From a clinical perspective, this progress is largely positive. Digital workflows improve efficiency, accuracy, collaboration and the patient experience. From a cybersecurity perspective, however, dentistry has shifted from a contained environment to a complex digital ecosystem, often without fully realising the implications. This article explains where cyber risks commonly arise within modern dental workflows and what clinicians need to consider before adopting digital technologies and what to monitor afterwards—in practical, non-technical terms. It aims to support safe, resilient and trustworthy digital dentistry.
