Dental Negligence Claims

Dental Negligence: Overview

Dental negligence is a sub-category of clinical negligence and is governed by the same principles as any other clinical claim: the claimant must prove that the practitioner breached the standard of a reasonably competent dentist (or relevant dental professional), and that the breach caused identifiable harm that would otherwise not have occurred.

Although dental claims rarely involve life-threatening injuries, they often involve substantial long-term consequences — disfigurement, chronic pain, permanent nerve damage, loss of teeth, and the considerable cost of remedial treatment, which can extend over many years.

The Standard of Care in Dentistry

The Bolam test applies. A dentist is judged against the standard of a reasonably competent dentist practising in the same area of dentistry. A general dental practitioner offering routine restorative care is not held to the standard of a specialist endodontist or oral surgeon — but a GDP who undertakes complex treatment beyond their training will be judged against the standard of the specialist who would ordinarily perform that work.

The General Dental Council's Standards for the Dental Team sets out the professional duties of all dental registrants and is regularly cited in dental negligence litigation as evidence of the applicable standard.

Common Dental Negligence Claims

• Failure to diagnose decay, periodontal disease or oral cancer
• Negligent extractions — wrong tooth, retained roots, or fractured jaw
• Nerve injury during extractions, implant placement or root canal treatment
• Failed root canal treatment and untreated infection
• Substandard crown, bridge, veneer or denture work
• Failed or poorly placed dental implants
• Orthodontic negligence — failed treatment plans, root resorption, relapse
• Failure to obtain informed consent for treatment options and risks

Nerve Injury Claims

Injury to the inferior alveolar nerve or the lingual nerve is one of the most common and serious categories of dental negligence claim. These nerves run close to the lower wisdom teeth and can be damaged by negligent extraction technique, failure to interpret pre-operative imaging, or by proceeding with extraction in circumstances where referral to an oral surgeon was clinically indicated.

The consequences include permanent numbness, altered sensation, or chronic neuropathic pain affecting the lip, chin, tongue and gums — with significant impact on speech, eating and quality of life.

Failed Dental Implant Claims

Implant dentistry is increasingly the subject of negligence claims, particularly where treatment is delivered by practitioners with limited implant training. Recognised failures include:

• Inadequate bone assessment or failure to obtain CBCT imaging
• Implants placed at an incorrect angle or depth
• Implants placed through the maxillary sinus or into the mandibular nerve canal
• Failure to manage peri-implantitis or recognise early implant failure
• Inadequate informed consent regarding risks, alternatives and long-term costs

Periodontal Neglect

Periodontal disease is progressive but treatable. A dentist who provides routine examinations over many years without ever conducting basic periodontal screening, communicating a diagnosis, or referring for periodontal treatment may be liable for the avoidable loss of teeth and supporting bone that follows.

Periodontal neglect claims are among the highest-value categories of dental negligence claim because the remedial cost — bone grafting, implants and long-term maintenance — can run into tens of thousands of pounds.

Missed Oral Cancer Diagnosis

Dentists have a recognised duty to screen for oral cancer at routine examinations and to refer suspicious lesions on the urgent suspected-cancer pathway. A dentist who repeatedly examines a patient and fails to recognise or refer a visible lesion — leading to a more advanced-stage diagnosis and worsened prognosis — may face a substantial negligence claim.

NHS vs Private Dentistry

The legal test for negligence is identical regardless of whether treatment was provided on the NHS or privately. The standard of care does not change based on the funding arrangement.

The difference lies in who the defendant is and how the claim is administered. NHS dentists are independent contractors and indemnify themselves through a dental defence organisation. Private dentists carry their own professional indemnity insurance. Either way, a claimant deals with the indemnifier rather than the individual dentist personally.

Compensation for Dental Negligence

Compensation comprises general damages for pain, suffering and loss of amenity, plus special damages for the cost of remedial dental work, lost earnings, travel, and any consequential losses. Remedial costs are frequently the largest component — particularly in implant, periodontal, and full-mouth reconstruction cases.

Time Limits for Dental Negligence Claims

Three years from the date of the negligent treatment or the date of knowledge — whichever is later. Periodontal neglect claims often rely on date of knowledge, because the harm only becomes apparent on a later referral to a specialist.
