If a dentist’s treatment fell below a reasonable standard and caused you harm, you may be able to claim compensation for dental negligence. The legal test is whether the care met the standard of a reasonably competent dentist. Common claims include nerve damage from extractions or implants, unnecessary extractions, failure to diagnose oral conditions, and botched crowns or bridges. You normally have three years to claim, but the clock can start from the date you first knew something was wrong (the “date of knowledge” rule).
Dental negligence claims are a distinct branch of medical negligence with their own practical features. Not every poor result is negligent — dentistry carries inherent risks, and a competent dentist can still have a complication. But where the treatment falls below what any reasonable dentist would do, and you suffer harm as a result, you can claim. This guide explains what dental negligence means, the most common claims, the difference between an NHS complaint and a civil claim, and where to get specialist help. We are an independent information service, not a law firm.
The standard of care
Dental negligence claims use the same legal tests as other clinical negligence:
- The Bolam test. The dentist’s treatment is measured against what a responsible body of dental practitioners would consider acceptable. If no competent dentist would have treated you that way, the care was below standard.
- The Montgomery principle. Since the Supreme Court decision in Montgomery v Lanarkshire Health Board (2015), a dentist must ensure you are aware of any material risks of a proposed procedure and of reasonable alternatives, so you can give informed consent. A failure of consent can be negligent even if the procedure itself was carried out competently.
- Causation. You must show that the substandard care (or failure to inform) caused you harm you would not otherwise have suffered.
Common dental negligence claims
| Scenario | What may have gone wrong |
|---|---|
| Nerve damage after extraction or implant | The inferior alveolar or lingual nerve was damaged during a procedure; the dentist may have failed to warn of the risk or performed the procedure below standard |
| Extraction of the wrong tooth | Failure to check records, X-rays or identity of the tooth |
| Failed or botched crowns, bridges or veneers | Poor fit, wrong bite, infection, or needing repeated remedial work |
| Failure to diagnose oral cancer or periodontal disease | Signs missed on examination or X-rays, leading to delayed treatment and worse outcomes |
| Unnecessary treatment | Fillings, extractions or root canals performed on teeth that did not need them |
| Infection or complications from root canal | Instrument breakage, perforation of the root, failure to treat all canals |
NHS treatment vs private treatment
The legal test for negligence is the same whether the treatment was NHS or private. The practical differences are:
- NHS claims are brought against the dental practice (or, in some structures, the NHS body that holds the contract). The practice’s indemnity insurer responds.
- Private claims are brought against the dentist or the private clinic. Most dentists carry professional indemnity through organisations such as the Dental Defence Union or the Medical and Dental Defence Union of Scotland.
- NHS complaints. You can complain through the NHS complaints procedure (the practice first, then the Parliamentary and Health Service Ombudsman). This can get you an explanation or an apology, and may result in remedial treatment, but it does not award compensation. A complaint and a civil claim can run at the same time.
The GDC: regulation, not compensation
The General Dental Council (GDC) is the regulator of dentists in the UK. You can report a dentist to the GDC if you believe there is a fitness-to-practise concern — serious or persistent failings, dishonesty, or a risk to patients. The GDC can impose conditions, suspend or strike off a dentist, but it does not award compensation. For compensation, you need a civil claim handled by a solicitor.
Time limits
You generally have three years to bring a dental negligence claim. In many cases this runs from the date of the treatment. But if you did not know at the time that you had suffered harm because of negligence — which is common in dental cases where problems emerge months or years later — the three years can run from the date of knowledge: the date you first knew, or should reasonably have known, that something was wrong. For children, the three years start at age 18. See our time limits guide.
Expert evidence
An independent dental expert report is essential in almost every dental negligence claim. The expert (a dentist in the relevant specialty) reviews your records, X-rays and clinical photographs and gives an opinion on whether the treatment fell below the expected standard, what the correct treatment would have been, and what harm the negligence caused. Without a supportive expert report, a claim is unlikely to succeed.
What compensation covers
General damages compensate for the pain, suffering and loss of function caused by the negligent treatment — ongoing dental pain, altered sensation, difficulty eating, cosmetic damage. Special damages cover the cost of remedial dental treatment (which can be substantial for implant or reconstructive work), lost earnings, travel and any other financial losses. See how compensation works.

Frequently asked questions
How do I know if my dental treatment was negligent?
Not every bad outcome is negligence. The legal test is whether the dentist's care fell below the standard of a reasonably competent dentist (the Bolam test). If a responsible body of dental practitioners would not have treated you that way, it may be negligent. You also need to show the substandard care caused you harm you would not otherwise have suffered. An independent dental expert assesses this.
Can I claim for nerve damage caused by a dentist?
You may be able to, depending on the circumstances. Nerve damage is a known risk of some dental procedures such as wisdom tooth extraction and implant placement. If the dentist warned you of the risk and performed the procedure competently, the outcome may be an accepted complication rather than negligence. But if the dentist failed to warn you (a consent issue) or performed the procedure below the expected standard, you may have a claim.
Should I complain to the GDC or to the NHS?
The General Dental Council (GDC) handles fitness-to-practise concerns and can take regulatory action against a dentist, but it does not award you compensation. The NHS complaints procedure can investigate your care and may offer an apology or remedial treatment, but again does not award compensation in the way a civil claim does. You can pursue a complaint and a civil claim at the same time.
How long do I have to claim for dental negligence?
Generally three years from the date of the negligent treatment, or three years from the date you first knew (or should reasonably have known) you had suffered harm because of negligence. This 'date of knowledge' rule is important in dental cases because problems can emerge months or years later. For children, the three years start at age 18.
Is dental negligence harder to prove than medical negligence?
The legal test is the same, but dental negligence claims have their own practical features. Dental records are often brief, which can make reconstructing what happened more difficult. An independent dental expert report is essential. However, many dental negligence claims are well supported by X-rays and clinical photographs, which can clearly show substandard work.
