One of the most common questions asked by people considering a dental negligence claim is: what evidence do I actually need? The reassuring answer is that you do not need to gather everything yourself — your solicitor will take on the heavy lifting. But understanding what evidence is required, why it matters, and what you can do to strengthen your position from the very start gives you a significant advantage.
Evidence serves three essential functions in a dental negligence claim. It proves that your dentist owed you a duty of care and breached it. It demonstrates that the breach caused your injury. And it quantifies what that injury has cost you — physically, psychologically and financially. A claim without solid evidence is extremely unlikely to succeed. A claim with comprehensive, well-organised evidence is far better placed to achieve a fair settlement — and to do so without the delay and cost of court proceedings.
In a dental negligence claim, the burden of proof rests with you as the claimant. You must show, on the balance of probabilities, that the dental professional’s treatment fell below the required standard and that this directly caused the harm you suffered. This cannot be established through assertion alone — it requires documentary evidence, professional expert opinion, and a clear chronological record of what happened and how it affected you.
The strength of your evidence directly affects three critical outcomes: whether a solicitor is able to accept your case on a No Win No Fee basis; whether the defendant admits liability early or disputes it; and ultimately, the amount of compensation you receive. The earlier you begin gathering and preserving evidence, the stronger your position.
Your dental records are the single most important piece of evidence in any dental negligence claim. They form the factual foundation upon which everything else is built — establishing what treatment was planned, what was actually carried out, when it was carried out, and whether it was consistent with the standard of care expected of a competent dental professional.
Dental records relevant to a claim typically include:
You are legally entitled to request your dental records under UK GDPR. Contact your dental practice in writing — an email is sufficient — and they must provide them within one calendar month, free of charge. They cannot refuse without good reason. If they do, you can report the failure to the Information Commissioner’s Office (ICO). Your solicitor will also make a formal request on your behalf as part of the claims process.
An independent expert report is essential in virtually all dental negligence claims and is typically the most influential piece of evidence. A suitably qualified dental expert — chosen for their specialism in the area of dentistry relevant to your treatment — will review your dental records and provide a written professional opinion addressing two critical questions:
Without a supportive expert report on both breach and causation, it is very difficult to advance a dental negligence claim. Your solicitor will identify, instruct and pay for the appropriate expert as part of the No Win No Fee arrangement — you do not need to find or fund this yourself.
In many cases, you will be asked to attend an in-person examination with the expert, who will assess your current condition, any ongoing symptoms, and the treatment you are likely to need in the future.
Photographs provide powerful visual evidence of the physical harm caused by dental negligence. They are particularly valuable in claims involving visible damage — swelling, bruising, scarring, disfigurement, failed dental work, or tooth loss.
Take photographs as soon as possible after the negligent treatment, and continue to document your condition at regular intervals as it changes over time. Key moments to photograph include:
Ensure photographs are date-stamped. Store them securely and provide copies to your solicitor at the earliest opportunity.
A contemporaneous symptoms diary — written at the time, not reconstructed later — is one of the most persuasive forms of personal evidence you can produce. It provides a day-by-day account of how the dental negligence has affected your life, and it is extremely difficult for the defendant to challenge.
Start your diary immediately and record the following each day (or whenever relevant):
A simple notebook, a notes app on your phone, or a dated email to yourself all work equally well. The key is that it is written at the time — not compiled weeks later from memory. Courts give significantly more weight to contemporaneous records.
Financial evidence supports your claim for special damages — the quantifiable out-of-pocket losses you have suffered as a direct result of the negligence. Keep all of the following from the moment the negligence occurs:
Do not rely on memory to reconstruct these costs at a later stage. Keep a dedicated folder — physical or digital — for all financial evidence from the outset.
If anyone was present at your dental appointments — a partner, parent, friend or chaperone — their account of what was said and what happened can provide valuable corroboration of your own evidence. Witness evidence is particularly useful where:
Note down the contact details of any potential witnesses as soon as possible — memories fade quickly and people can become difficult to locate over time. Your solicitor will take formal witness statements when needed.
If the consequences of the dental negligence have required you to seek treatment beyond the dental practice itself — through your GP, at A&E, as a hospital inpatient or outpatient, or through a specialist referral — those medical records are important evidence of both the severity and the consequences of your injury.
You are entitled to request your GP and hospital records under UK GDPR in the same way as your dental records. Your solicitor will obtain these as part of the claims process.
Any written or electronic communication between you and the dental practice is potentially relevant evidence. This includes:
Do not delete any messages or emails from your dental practice. Even communications that appear routine — such as appointment reminders — can help establish a timeline of events. Screenshot text messages and archive emails to a secure folder.
Making a formal complaint to the dental practice or to the relevant regulatory body (the NHS Integrated Care Board for NHS patients, or the Dental Complaints Service for private patients) is not a legal requirement before bringing a claim — but the records generated by a complaint can provide useful additional evidence.
A complaint investigation may produce:
Do not allow the complaints process to eat into your three-year limitation period for bringing a legal claim. The two processes are separate and run concurrently. Seek legal advice while pursuing any complaint — do not wait for the complaint to conclude before instructing a solicitor.

You do not need to build your evidence file alone. Once you instruct a dental negligence solicitor, they take on the primary responsibility for obtaining and organising the evidence needed to support your claim. In practice, this means your solicitor will:
Your role is to provide your solicitor with the personal evidence that only you can supply — your symptoms diary, your photographs, your financial records and your witness contacts. The more thoroughly you have documented your experience, the more powerful the overall evidence package will be.
On the Pre-Action Protocol: Before any court proceedings are issued, both parties are required to follow the Pre-Action Protocol for the Resolution of Clinical Disputes.
This requires the claimant’s solicitor to send a detailed Letter of Claim to the defendant, who then has four months to investigate and respond. The quality of the evidence compiled at this stage frequently determines whether the case settles or proceeds to litigation.
Use this checklist to track the evidence you have already gathered and identify what still needs to be obtained. Share it with your solicitor at your first consultation.

You have a legal right to request your dental records under UK GDPR. Contact your dental practice in writing — email is sufficient — and they must provide your full records within one calendar month, free of charge. Your solicitor will also make a formal request as part of the claims process.
Yes, in almost all dental negligence cases. An independent expert will review your records and provide a written opinion on breach of duty and causation. Without a supportive expert report it is very difficult to establish the legal elements of a claim. Your solicitor will instruct and fund the expert as part of the No Win No Fee arrangement.
Record your daily pain levels and type of pain, difficulties eating, speaking or sleeping, medication taken and its effects, appointments attended, the emotional and psychological impact, and how the injury has affected your work, social life and daily routine. Write it contemporaneously — at the time, not from memory later.
A claim without evidence is very unlikely to succeed. Evidence is required to prove duty of care, breach and causation. However, you do not need to gather everything yourself — your solicitor will obtain dental records, commission expert reports and compile the evidence package on your behalf.
Keep all receipts and invoices for corrective dental treatment, medication, travel to appointments, and any private assessments. If you have lost earnings, retain payslips and employer correspondence. Bank statements can evidence out-of-pocket costs where formal receipts are unavailable.
No. Making a formal complaint is not a legal prerequisite to bringing a dental negligence claim. However, complaint records can provide useful supporting evidence. Importantly, do not allow the complaints process to delay instructing a solicitor — the three-year limitation period runs regardless of any ongoing complaint.
