Your dental practice holds detailed personal and medical information about you. GDPR governs how that data is stored, shared, and protected. Here's what your practice is required to do with your data.
Dental records contain some of the most sensitive information about you — your medical history, your treatments, your contact details, your payment information. GDPR — the General Data Protection Regulation — sets the rules for how your practice must handle all of it.
What Is GDPR?
GDPR stands for the General Data Protection Regulation. It came into force in 2018 and applies to all organisations that handle personal data in the UK, including dental practices. It sets out what personal data is, how it must be collected, stored, used, and shared, and what rights you have over your own data.
The Information Commissioner's Office (ICO) is the independent authority that enforces GDPR in the UK. Dental practices are accountable to the ICO.
What Data Does Your Dental Practice Hold About You?
Your dental records include your name, address, date of birth, contact details, medical history, dental history, treatment plans, X-rays and photographs, notes from appointments, and payment or insurance information. All of this is personal data under GDPR.
Some of it — your medical history and treatment details — is classified as special category data, which means it needs even stronger protection than standard personal data.
What Is Your Practice Required to Do With Your Data?
Several things. First, your practice must have a lawful basis for collecting and using your data. For most dental treatment, the lawful basis is that it's necessary for the performance of a contract — your dental care. For some uses, like appointment reminders by text, consent may be the basis.
Your practice must also tell you what data it holds, why it holds it, how long it keeps it, and who it shares it with. This is usually provided in a privacy notice.
How Must Your Practice Protect Your Data?
GDPR requires your practice to take appropriate technical and organisational measures to protect your data. This includes secure storage (whether physical or digital), restricted access (only staff who need your data can see it), staff training on data protection, and having a data breach response plan.
If there is a data breach that could harm you — for example, your data is lost or stolen — your practice is required to report it to the ICO within 72 hours and to tell you directly if the breach is serious.
What Rights Do You Have Over Your Data?
Under GDPR, you have several rights. You have the right to know what data is held about you and to access it — you can ask for a copy of your records. You have the right to have inaccurate data corrected. You have the right to request deletion of your data in certain circumstances. You have the right to object to how your data is used, and the right to data portability.
To exercise any of these rights, you contact your practice directly. They have one month to respond.
How Long Does Your Practice Keep Your Records?
Dental records must be kept for a minimum period — the standard recommendation is at least 10 years after the last appointment, or longer for children until they reach the age of 25. Your practice has a data retention policy that sets out exactly how long records are kept.
After that period, records must be securely destroyed.
What Does This Mean for You?
It means your personal and medical information is taken seriously. Your practice has legal obligations around how it handles your data, and you have clear rights. If you ever have a question or concern about how your data is being used, you can ask your practice or raise it directly with the ICO.
