Can You Request Your Original Diagnostic X-Rays and Scans Under UK GDPR Laws?
Introduction
Many patients reach a point where they need their dental records — perhaps they are moving to a new practice, seeking a second opinion, or considering orthodontic treatment and want to share previous scans with a new provider. A common question that arises is whether you have a legal right to obtain copies of your diagnostic X-rays, CBCT scans, or other dental imaging, and what that process actually involves.
The short answer is yes — under UK data protection law, you generally have the right to access your personal health data, including diagnostic dental images. However, understanding exactly how that right works, what you can request, what limitations may apply, and how dental practices are expected to respond can feel confusing without clear guidance.
This article explains your rights to request dental X-rays and diagnostic scans under UK GDPR, how the process works in practice, what to do if your request is not handled appropriately, and when obtaining previous dental records may be particularly relevant — for example, when exploring orthodontic or other dental treatment options.

Can you request your dental X-rays and diagnostic scans under UK GDPR?
Yes. Under UK GDPR and the Data Protection Act 2018, you have the legal right to request access to your personal health data, including dental X-rays and diagnostic scans held by your dental practice. This is called a Subject Access Request (SAR). Your dental practice must respond within one calendar month and generally cannot charge a fee.
What Is a Subject Access Request (SAR) in the Context of Dental Records?
A Subject Access Request, commonly abbreviated to SAR, is a formal request made by an individual to an organisation asking to see the personal data held about them. This right is established under Article 15 of UK GDPR, which is the version of the General Data Protection Regulation that applies in the United Kingdom following Brexit, alongside the Data Protection Act 2018.
In a dental setting, your personal data includes:
- Clinical notes and treatment records
- Correspondence relating to your care
- Referral letters
- Diagnostic X-rays and radiographs
- Intraoral scans
- CBCT (cone beam computed tomography) scans
- Treatment plans and clinical photographs
All of the above are considered personal data under UK law, because they relate to an identifiable individual's health. This means you have the right to request access to them.
How Do You Make a Subject Access Request to a Dental Practice?
Making a SAR to a dental practice does not need to follow a specific format. You can submit your request:
- In writing — by letter or email to the practice
- Verbally — in person or by telephone, although written requests are easier to evidence
When making your request, it is helpful to:
- Clearly state that you are making a Subject Access Request under UK GDPR
- Specify the data you are seeking — for example, all clinical notes, dental X-rays and diagnostic scans from a particular period
- Provide your full name, date of birth and any previous addresses if you have moved, so the practice can locate your records accurately
- Include proof of identity if the practice requests this — practices are entitled to ask for reasonable verification before releasing data
You do not need to give a reason for your request, though it may help to explain your purpose informally if it would assist the practice in locating the relevant data efficiently.
What Are the Legal Timeframes and Costs?
Under UK GDPR, the dental practice must respond to your Subject Access Request within one calendar month of receiving the request. In cases of complexity or where a large volume of data is involved, this can be extended by a further two months, but the practice must inform you of this extension and the reason within the first month.
In most cases, dental practices cannot charge a fee for providing access to your records. However, if a request is deemed "manifestly unfounded or excessive" — for example, if the same individual makes repetitive identical requests — the practice may charge a reasonable administrative fee or refuse the request, provided they can justify this decision.
If you are requesting paper copies rather than electronic records, the practice may in some circumstances charge for the cost of reproducing documents, but they cannot charge for the data itself.
Do You Have the Right to Receive the Actual Images?
This is a nuance that patients often find confusing. UK GDPR gives you the right to access your personal data and to receive a copy of it. In practical terms, this means:
- You are entitled to receive copies of your dental radiographs and scans
- These may be provided as printed copies, digital files on a disc or USB, or via secure electronic transfer
- You are generally not entitled to remove the physical original X-ray film or original digital file from the practice's own records — the practice retains its own copy
It is worth noting that dental X-rays and scans are often stored in proprietary software systems. If a practice provides images in a format that requires specialist software to open, it is reasonable to ask whether they can provide the images in a more universally accessible format, such as JPEG or PDF where technically feasible.
Why Might You Need Your Dental X-Rays and Scans?
There are several legitimate and practical reasons why a patient may wish to obtain copies of their dental diagnostic imaging:
Changing Dental Practice
When registering with a new dental practice, having access to your previous X-rays can reduce the need for immediate repeat imaging. This is both practically convenient and reduces any unnecessary radiation exposure.
Seeking a Second Opinion
If you have been given a treatment recommendation — for example, regarding a surgical procedure, restorative treatment or complex extraction — you may wish to obtain a second clinical opinion. Sharing your existing diagnostic images with another appropriately qualified dental professional can facilitate that assessment.
Orthodontic Assessment
Orthodontic treatment planning sometimes involves reviewing existing diagnostic records, including panoramic radiographs (OPGs), periapical X-rays, lateral cephalometric radiographs or CBCT scans. If you are considering orthodontic options — whether conventional fixed braces or clear aligner treatment — your orthodontic provider may ask whether you have existing imaging available.
For patients exploring how clear aligner treatment is assessed and planned, understanding what an orthodontic consultation typically involves can be a useful starting point before gathering records.
Insurance or Medico-Legal Purposes
In some circumstances, patients require dental records for insurance claims, personal injury cases or complaints procedures. A SAR is the appropriate mechanism for obtaining this information.
What If the Dental Practice Refuses or Does Not Respond?
If a dental practice fails to respond to your Subject Access Request within the required timeframe, or refuses your request without appropriate justification, you have the following options:
- Contact the practice directly — sometimes delays occur due to administrative reasons, and a follow-up communication can resolve the matter
- Raise a complaint with the dental practice — most practices have a formal complaints procedure
- Contact the Information Commissioner's Office (ICO) — the ICO is the UK's independent regulatory authority responsible for data protection law. You can report non-compliance to the ICO and request an investigation. The ICO can take enforcement action where organisations fail to comply with their legal obligations under UK GDPR
- Seek independent advice — organisations such as the Citizens Advice Bureau or a solicitor with data protection experience can provide further guidance
The General Dental Council (GDC) also expects dental professionals to maintain and manage patient records appropriately, in line with its published standards.
Dental Records, Retention Periods and What Happens When a Practice Closes
It is important to understand that dental records — including X-rays — are subject to recommended retention periods. Under guidance from professional bodies, adult dental records are generally recommended to be retained for a minimum of ten years from the date of the last entry, or until the patient reaches the age of 25 years, whichever is longer.
If a dental practice has closed, records should have been transferred to another provider, a records management service, or — in some cases — may have been submitted to NHS structures. If you are struggling to locate records from a closed practice, contacting NHS England (for NHS records) or seeking advice from the Dental Defence Union (DDU) or other professional bodies may assist.
When Are Diagnostic Dental X-Rays Clinically Important?
Dental X-rays are not simply administrative documents — they represent clinical diagnostic information that can be directly relevant to future dental care. This includes:
- Bone levels and periodontal (gum) health, which are important for assessing suitability for certain treatments including orthodontic tooth movement
- The presence of unerupted, impacted or missing teeth
- Root anatomy and canal morphology
- The health of existing restorations
- Signs of caries (decay) in areas not visible during a clinical examination
- Jaw anatomy relevant to surgical planning
For patients considering tooth alignment treatment, previous diagnostic imaging can sometimes inform decisions about treatment approach. Patients with questions about orthodontic records and how clear aligners are used for different alignment concerns may find it helpful to discuss their existing records with an appropriately qualified provider.
The Relationship Between Dental Records and Oral Health Continuity
One of the broader reasons why accessing and maintaining continuity of dental records matters is the importance of ongoing oral health monitoring. Good oral health is closely associated with general wellbeing, and longitudinal dental records — including successive sets of radiographs — allow dental professionals to monitor changes over time, such as:
- Progressive bone loss associated with periodontal disease
- Changes in existing restorations
- Development of new areas of concern
- The stability of previous orthodontic treatment outcomes
Patients who have previously completed orthodontic treatment may be particularly aware of the importance of retaining records, as these can be relevant if tooth movement is observed over time. Patients curious about orthodontic retention and preventing teeth from shifting after treatment may find it useful to understand how post-treatment monitoring works.
When Should You Speak to a Dental Professional?
You should consider speaking to a dentist or other appropriately qualified dental professional if:
- You are changing dental practice and want to ensure records are transferred correctly
- You are considering any form of dental treatment and want to understand what previous imaging exists
- You have been advised you need treatment and wish to seek a second opinion
- You are experiencing persistent dental symptoms — including pain, sensitivity, swelling, bleeding gums or changes in how your teeth feel or meet — that have not been investigated
- You are considering orthodontic assessment and want to understand whether your previous records are relevant
If you have specific concerns about dental alignment or are exploring options such as clear aligner treatment, patients with misalignment concerns including crowded teeth or spacing issues may benefit from an initial consultation with an orthodontic provider to understand what records may be needed.
For general oral health concerns, your registered dentist remains the appropriate first point of contact.
Practical Tips for Maintaining Your Own Dental Records
While your dental practice holds the official records, it can be helpful to:
- Keep copies of any significant X-rays or scans provided to you
- Note the dates and names of practices you have attended, and approximate dates of X-rays taken
- Keep copies of referral letters or specialist reports
- Keep a record of treatments you have received, including any orthodontic appliances, restorations or extractions
- Store any orthodontic retainers or appliance information carefully
This can be particularly useful if you relocate, change dentist, or require treatment from a specialist who benefits from understanding your dental history.
Prevention and Good Oral Health
Regardless of the administrative aspects of dental records, the most effective strategy for long-term dental health remains consistent preventive care. The NHS and UK dental professionals broadly recommend:
- Brushing teeth twice daily with a fluoride toothpaste
- Cleaning between teeth daily using floss, interdental brushes or water flossers as appropriate
- Attending regular dental examinations at intervals recommended by your dentist
- Reducing the frequency of sugary food and drink consumption
- Not smoking or using tobacco products
- Informing your dentist of any changes in your general health or medications
If you are undergoing or have completed orthodontic treatment, maintaining meticulous oral hygiene is particularly important, as are any retainer-wearing instructions provided by your orthodontic professional.
For patients with questions about how clear aligners are maintained and cleaned during treatment, understanding the day-to-day responsibilities of treatment can inform decision-making.
Key Points to Remember
- You have the legal right to request copies of your dental X-rays and diagnostic scans under UK GDPR via a Subject Access Request.
- Dental practices must respond within one calendar month and generally cannot charge a fee for providing access to your records.
- You are entitled to copies of your diagnostic images — not necessarily the original files — and the practice retains its own records.
- If a request is refused or ignored, you can escalate to the Information Commissioner's Office (ICO).
- Dental records, including X-rays, are clinically relevant and can be important when changing practices, seeking second opinions or considering new treatments.
- Dental records are subject to retention periods, and records from closed practices may require additional steps to locate.
Frequently Asked Questions
Can a dental practice charge me for copies of my X-rays?
In most circumstances, no. Under UK GDPR, organisations generally cannot charge for responding to a Subject Access Request. However, if your request is considered manifestly unfounded or excessive, or if you are requesting printed copies that incur genuine reproduction costs, a reasonable fee may sometimes apply. The practice must be transparent about any charge and its justification. If you are uncertain whether a charge is appropriate, you can seek guidance from the Information Commissioner's Office.
How long does a dental practice have to keep my X-rays?
Dental records, including radiographs, are generally recommended to be retained for a minimum of ten years from the date of the last entry for adult patients, or until the patient reaches the age of 25 years if they were treated as a child, whichever is longer. These are professional guidance recommendations rather than absolute statutory requirements, but most practices follow them as a standard of care. If you are concerned that records from a specific period may have been destroyed, contact the practice directly.
What should I do if my old dental practice has closed?
If the practice was an NHS practice, NHS England may be able to assist in locating records. For private practices, the practice owner or records management company that took on the records may hold the data. Relevant professional indemnity organisations such as the Dental Defence Union (DDU) or Dental Protection may sometimes be able to offer guidance. It is worth making enquiries promptly, as records may only be retained for the recommended retention period.
Do I need to give a reason for requesting my dental X-rays?
No. Under UK GDPR, you are not required to provide a reason for making a Subject Access Request. You simply need to make the request clearly, provide sufficient information for the practice to identify you and locate your records, and — if asked — verify your identity. The practice cannot refuse your request simply because they disagree with your reasons for making it.
Can my dental X-rays be used for orthodontic treatment planning?
Dental X-rays can provide clinically useful information for orthodontic assessment, depending on their type, recency and quality. A panoramic radiograph (OPG), for example, may provide an overview of tooth position, root anatomy, bone levels and unerupted teeth that is relevant to treatment planning. Whether any particular image is useful for a specific purpose would depend on clinical assessment by the treating orthodontic professional. Individual suitability for orthodontic treatment — including clear aligner options — always requires a dedicated clinical examination.
What is the ICO and how can they help?
The Information Commissioner's Office (ICO) is the UK's independent regulatory body responsible for overseeing data protection law, including UK GDPR and the Data Protection Act 2018. If you believe that a dental practice has failed to respond to your Subject Access Request appropriately, has unlawfully refused your request, or has otherwise breached your data rights, you can report this to the ICO via their website. The ICO can investigate complaints, issue guidance and — where necessary — take enforcement action against organisations that fail to comply with data protection law.
Conclusion
Understanding your rights under UK GDPR regarding dental X-rays and diagnostic scans is a practical and important aspect of managing your own healthcare. The right to make a Subject Access Request is well-established in UK law, and dental practices are expected to respond appropriately, within the required timeframe and generally without charge.
Accessing your dental records and diagnostic images can be relevant in a number of situations — from changing practices to seeking specialist assessment or considering orthodontic treatment options. Having a clear understanding of the process, and knowing what to do if a request is not handled correctly, can help you navigate these situations with confidence.
Whether treatment is appropriate depends on the individual's dental health, clinical findings and treatment goals, and should be assessed during an appropriate clinical examination.
If you have concerns about your dental health, diagnostic records or treatment options, speaking to a registered dental professional remains the appropriate first step.
