What you need to know
Short answerA dental negligence claim succeeds where expert evidence shows the dentist failed to meet the standard of a reasonably competent practitioner (the Bolam test) and that this caused avoidable injury — for example progressive periodontal bone loss, nerve damage or wrong-tooth extraction. The standard time limit is three years.
Common dental negligence claims
- Periodontal (gum) disease — failure to diagnose, monitor, treat or refer. One of the most common UK dental claims.
- Wrong-tooth extraction — a recognised "Never Event" that almost always indicates negligence.
- Nerve injury — particularly the inferior alveolar or lingual nerve during extractions or implant placement.
- Root canal failures — perforations, missed canals, fractured instruments left in situ.
- Restorative work — poorly fitting crowns, bridges or veneers leading to decay or loss of the underlying tooth.
- Failure to spot oral cancer — not examining soft tissue, ignoring persistent ulcers or red/white patches.
- Consent failures — risks of treatment not explained (the Montgomery standard applies to dentists too).
Proving the claim
You need your full dental records (charts, periodontal scores, X-rays, consent forms, treatment notes) and an independent expert report from a dentist of equivalent experience. For periodontal claims, X-rays over time often show how the disease should have been diagnosed and treated years earlier.
NHS vs private dental claims
The legal test is identical. The difference is regulatory: NHS dentists must also meet the NHS contract standards, and private treatment must comply with the General Dental Council's Standards for the Dental Team. Patients can also complain to the GDC about a registrant's fitness to practise — separately from a compensation claim.
Frequently asked questions
Can I claim compensation for dental negligence in the UK?
Yes. Dentists owe their patients a legal duty of care under the same Bolam/Bolitho framework as doctors. If a dentist's treatment fell below the standard of a reasonably competent dentist and caused you avoidable harm, you can claim — whether the treatment was on the NHS or private.
What are the most common dental negligence claims?
Failure to diagnose and treat periodontal (gum) disease, wrong-tooth extraction, nerve injury during extractions or implants, mismanaged root-canal treatment, badly fitting crowns or bridges, mismanaged orthodontics, and failure to spot oral cancer.
Is the time limit different for dental claims?
No. The standard three-year limitation period under section 11 of the Limitation Act 1980 applies. Date of knowledge is often important in dental cases because the harm (e.g. progressive bone loss from undiagnosed periodontitis) may only become obvious years later.
Who do I claim against — the dentist or the practice?
Usually the individual dentist who treated you, who will be indemnified by a dental defence organisation such as Dental Protection or DDU. NHS primary-care dentists are not indemnified through NHS Resolution — claims are pursued through their indemnity provider.
