Top reasons dentists get sued, and how those cases are won or lost
Spring is peak time for check-ups and elective treatments. It is also when many people notice lingering problems from earlier dentistry and start to ask whether what happened was avoidable. If that is you, you are not alone.
Dental malpractice law is about evidence, not emotion. Strong cases turn on two questions: did the dentist breach their duty by falling below a reasonable standard, and did that breach cause your injury and loss. Below, we walk through the allegation types we see most often, what needs proving for each, the evidence that moves the dial, and how outcomes are usually reached.
If you recognise your experience in any of these scenarios, our specialist solicitor can review eligibility for free and explain funding options, including No Win No Fee.
The legal core: breach and causation
Every successful dental negligence claim must establish:
Breach of duty: treatment fell below a reasonable standard expected of a competent practitioner in that situation.
Causation: that breach more likely than not caused your injury, additional treatment, or financial loss.
Independent expert reports sit at the heart of both issues. Records, imaging and clear timelines either support or undermine the link between what went wrong and the harm you suffered.
Misdiagnosed periodontal disease
What goes wrong: missed or late diagnosis of gum disease, inadequate periodontal charting, failure to record bleeding or pocket depths, and failure to refer. Over time this can lead to avoidable bone loss, tooth mobility and tooth loss.
Proving it: we compare your notes and x-rays over time. A breach is often shown by absent or sparse periodontal records despite red flags. Causation turns on whether earlier diagnosis and therapy would probably have preserved bone or teeth.
Evidence: full dental records, radiographs, any CBCT scans, recall intervals, hygiene notes, and photographs. A periodontist expert typically reports on breach, causation and prognosis.
Outcomes: damages often include ongoing periodontal therapy, replacement of lost teeth, and pain and suffering. Claims can resolve pre-action when the record is clear and expert opinion is strong.
Wrong tooth extraction
What goes wrong: a healthy tooth is removed instead of the intended one.
Proving it: the breach is usually self-evident once records and treatment plans are reviewed. Causation is also clear, but quantum varies with the replacement plan and cosmetic impact.
Evidence: consent forms, treatment plans marking the intended tooth, pre-op and post-op x-rays, and correspondence.
Outcomes: settlements typically cover replacement options such as implant or bridge, associated grafting where indicated, time off work and general damages.
Failed implants from poor planning
What goes wrong: inadequate assessment of bone and gum, insufficient imaging or planning, wrong angulation or depth, or poor postoperative monitoring leading to peri-implantitis or failure.
Proving it: breach is shown where planning deviated from reasonable implant protocols. Causation examines whether the planning or surgical error, rather than patient risk factors alone, led to failure.
Evidence: pre-op assessment notes, CBCT scans, surgical guides, operative notes, postoperative reviews and photographs. Implant specialist reports are essential.
Outcomes: where breach and causation are supported, damages normally include removal, staged replacement, grafting, temporary prostheses and general damages. Many cases settle after expert evidence is exchanged.
Inadequate consent
What goes wrong: consent that is generic or rushed, missing discussion of material risks, reasonable alternatives, or the option of doing nothing.
Proving it: breach is established where the consent process was not tailored to you and material risks were not properly explained. Causation asks whether, had you been properly informed, you would likely have declined or chosen a different option.
Evidence: consent forms, consultation notes, leaflets provided, and your witness statement about what was discussed. An expert assesses both standard of consent and clinical context.
Outcomes: consent-only cases can be nuanced. They are stronger where the undisclosed risk materialised and a credible alternative path existed.
Nerve injuries
What goes wrong: lingual or inferior alveolar nerve damage after extractions, implant placement, endodontics or injections, causing numbness, tingling, burning or taste disturbance.
Proving it: breach may be shown by poor planning, incorrect technique, or inadequate warnings of nerve risk. Causation focuses on timing of symptoms and imaging findings.
Evidence: operative notes, cone beam CT or other imaging, symptom diary, neurosensory assessments, and early postoperative records. Oral surgery experts commonly report.
Outcomes: compensation reflects severity and persistence of altered sensation, plus costs of remedial care and aids. Early symptom diaries can materially strengthen valuation.
Substandard root canal treatment
What goes wrong: missed canals, inadequate cleaning and sealing, perforations, overfilling, or untreated infection leading to persistent pain, infection or tooth loss.
Proving it: breach is demonstrated through radiographic analysis and expert critique of technique. Causation asks whether proper treatment would likely have saved the tooth or avoided further surgery.
Evidence: pre and post-op x-rays, notes on working lengths and obturation, subsequent retreatment or extraction records. Endodontist expert input is key.
Outcomes: damages often cover retreatment or apicectomy, crown replacement if needed, or extraction and replacement where prognosis is poor.
Cosmetic dentistry failures
What goes wrong: over-preparation for veneers, poor aesthetics, repeated debonding, altered bite and sensitivity.
Proving it: breach flows from preparation beyond what was reasonable, poor planning or cementation, and lack of occlusal assessment. Causation is usually straightforward when symptoms and failures follow shortly after treatment.
Evidence: pre-treatment photographs and shade records, preparation photos, lab prescriptions, bite records and follow-up notes. Prosthodontist reports are common.
Outcomes: claims include replacement or revision work, bite adjustment, possible endodontics where dentine exposure occurred, and general damages.
How hard are dental malpractice cases to win?
They are evidence-heavy and expert-led, not automatically difficult. Cases with clear records, supportive expert opinions and a logical causation story often settle before trial. Myths to ignore:
Myth: if something went wrong, you will be compensated. Reality: you must prove both breach and causation.
Myth: consent forms block all claims. Reality: generic forms do not cure poor consent or negligent treatment.
Myth: NHS cases cannot be won. Reality: principles are the same for NHS and private care, though procedures differ.
What a strong case typically includes
Early preserved records and imaging
A consistent symptom diary, especially for nerve issues
Independent expert reports addressing breach, causation and prognosis
A worked schedule of loss covering remedial costs, travel, medication, lost earnings and pain and suffering

FAQs
What do dentists get sued for the most?
Common allegations include mismanaged periodontal disease, wrong tooth extraction, failed implants due to poor planning, inadequate consent, nerve injuries, substandard root canal treatment and cosmetic failures.
Are dental malpractice cases hard to win?
They can be challenging without evidence, but with solid records and credible expert opinions many cases settle. The difficulty varies with the clarity of breach and causation.
How do you prove dental negligence?
By showing a breach of duty and linking it to your injury and losses. Independent expert reports, records, imaging and a clear timeline are central.
What is an example of negligence in dentistry?
Extracting the wrong tooth, missing canals during a root canal, placing an implant without adequate imaging, or failing to diagnose progressing gum disease despite red flags.
How long does it take to settle a dental malpractice lawsuit?
Timelines vary. After a letter of claim, defendants often have up to four months to respond. If litigation is needed, issue to trial can take around 12 months or more. Many claims settle once expert reports are exchanged.
A supportive next step
If you suspect negligent dental treatment, prioritise your health first. Seek urgent care for severe pain, infection or new numbness via NHS 111 or emergency dental services. Then preserve your evidence, including notes, x-rays, photographs and receipts.
