Why cyber security must be a priority for dentists and dental practices

Dentistry is increasingly digital and online bookings, cloud-based practice management systems, digital imaging, e-prescribing, remote access, and card payments are now routine. But this reliance on technology brings real risk. Cyber criminals are faster, more targeted and increasingly using AI to scale phishing and impersonation attacks. Unfortunately, dental practices can be easy targets for those looking to exploit vulnerable systems. Like many SMEs, practices often run lean teams and outsource IT. Attackers know smaller organisations may not have the same layered controls as larger ones, making them attractive targets. The threat is widespread: the UK Government’s Cyber Security Breaches Survey 2025/2026 found that 43% of businesses reported a cyber breach or attack in the past 12 months, with phishing the most prevalent and disruptive threat affecting 38% of businesses.

Personal data at risk

For dentistry, the stakes are particularly high because of the data you hold. Patient records aren’t just names and contact details — they can include medical histories, treatment plans, NHS/private payment information, insurance details, correspondence and sometimes ID documents. If accessed, stolen or encrypted by ransomware, the consequences can be severe and lead to cancelled clinics, delayed care, regulatory exposure under GDPR, financial loss and reputational damage.

Cyber security needs to be approached as a profession-wide issue, not just an IT problem. Associates may access systems across multiple sites, team members use email daily, suppliers send invoices and payment requests, and practice owners often approve payments while on the move. Many successful incidents start with human error, such as clicking a convincing email link or approving a fraudulent change of bank details, which is why regular security awareness training and clear processes matter.

What should practices prioritise now?

Start with the basics (multi-factor authentication on email and core systems, regular patching of devices and systems, secure, tested backups), then take a structured approach. You will need to understand vulnerabilities, test your response, and build a culture of awareness. Armstrong Watson’s Cyber Security Solutions can help dental practices assess risk, implement employee training, test incident response plans and strengthen compliance - helping protect patient data and maintain continuity of care.
