Dental Negligence Compensation Calculator

How much compensation can I claim for dental negligence?

Dental negligence covers a wide range of failures by a dentist, hygienist or orthodontist that fall below an acceptable standard of care – from extracting the wrong tooth or fitting a failed implant, to missing gum disease until it causes bone loss, or damaging a nerve during root canal or wisdom tooth removal. If you can show the treatment fell below what a responsible body of dental professionals would consider acceptable, and that this caused you harm, you may be entitled to compensation. This calculator gives an estimated range for general damages (pain, suffering and loss of amenity), using published Judicial College Guidelines (JCG) bands for damage to teeth, plus the cost of corrective private treatment and any lost earnings. It is built for UK patients – both NHS and private – who want a realistic starting figure before contacting a solicitor. Every case is different, and a final valuation depends on an independent dental expert's report.

How the estimate is worked out

The calculator combines two elements:

• General damages – an indicative band for pain, suffering and loss of amenity caused by the negligent treatment itself, ranging from minor (corrected quickly with limited further treatment) through to severe cases involving permanent nerve damage or extensive reconstruction.
• Special damages – your actual financial losses. The most common is the cost of corrective private dental treatment (implants, crowns, bridges or root canal re-treatment), plus any lost earnings if you needed time off for appointments, surgery or recovery.

Wrong-tooth extractions and single failed implants that are correctable with further dental work typically sit at the lower to middle of the scale. Missed periodontal disease that leads to multiple tooth loss, or nerve damage causing lasting numbness, altered sensation or chronic pain (paraesthesia or dysaesthesia of the lingual or inferior alveolar nerve), sits at the higher end because the damage is often permanent and affects eating, speech and confidence.

Worked example

Sarah went to her dentist for a routine extraction, but the dentist removed the wrong tooth – a healthy molar instead of the decayed one next to it. She needed a bone graft and a dental implant to replace it, at a private cost of £3,200, and used annual leave for her two follow-up appointments so had no separate lost-earnings claim. Her case is classed as moderate (£7,510–£14,780 general damages). Adding her treatment costs, her total estimated claim falls in the region of £10,710 to £17,980. A solicitor would request her dental records from both the original and corrective dentist, and may instruct an independent dental expert to confirm the extraction was avoidable and negligent.

Who can claim?

You may have grounds for a claim if:

• Your treatment fell below the standard expected of a reasonably competent dentist – assessed against the Bolam test (whether a responsible body of dental opinion would have acted the same way) and the Montgomery test (whether you were properly informed of material risks and alternatives before consenting).
• The negligence caused demonstrable harm – unnecessary tooth loss, a failed or infected implant, nerve damage, or a delayed diagnosis that allowed a treatable problem (such as gum disease or oral cancer) to progress.
• You are within the standard three-year time limit, running from the date of the negligent treatment or from the date you first knew (or reasonably should have known) that your ongoing problem was caused by it.
• You have supporting evidence – dental records, X-rays, photographs and, ideally, a second dentist's opinion on the corrective treatment needed.

Common mistakes that reduce a claim

The biggest mistake is delaying corrective treatment or a second opinion, which can make it harder to prove the original treatment (rather than a new problem) caused your current condition. Also avoid agreeing to further treatment from the same practice without independent advice if you suspect negligence, as this can complicate the causation picture. Keep every receipt for private corrective treatment, request copies of your full dental records and X-rays in writing (you are entitled to these), and get a written report from your new dentist describing what was found and what work was required. NHS patients should also be aware that if the original treatment was NHS-funded, the claim is generally still a personal injury claim against the treating dentist or practice, not a formal NHS complaint (though you can pursue both in parallel).

What affects how much you're awarded

Number of teeth affected and whether damage is permanent are the two biggest factors. A single tooth that is successfully replaced with an implant is valued far lower than multiple tooth loss or nerve damage causing permanent numbness of the lip, tongue or chin. Cosmetic impact matters too – damage to a visible front tooth, or a change to your bite or facial appearance, can increase an award even where the underlying dental work is technically straightforward to correct. Ongoing pain or altered sensation (such as damage to the lingual or inferior alveolar nerve during wisdom tooth removal) is weighted heavily because it is frequently permanent and affects eating, speaking and daily comfort. As with all injury claims, psychological impact – for example dental anxiety that stops you seeking further necessary treatment – can also be claimed for separately where it is significant and supported by medical evidence.

The dentist's duty of care and how liability is assessed

All dentists practising in the UK must be registered with the General Dental Council (GDC) and are bound by its standards for the dental team, which require patients to be treated competently, safely and with properly informed consent. A negligence claim typically turns on expert dental evidence: an independent dentist reviews your records and treatment and gives an opinion on whether the standard of care fell below what a responsible body of the profession would support, and whether that failure caused the harm you are claiming for (causation). Claims against NHS dentists are usually brought against the treating dentist or practice directly (dental practices carry their own indemnity insurance, similar to how GPs are separately insured from hospital doctors under NHS Resolution), rather than against NHS England itself.

How the claims process works

Most dental negligence claims start with a free consultation with a solicitor who specialises in clinical negligence, usually offered on a no-win-no-fee (Conditional Fee Agreement) basis, so you pay nothing upfront and nothing at all if the claim does not succeed. Your solicitor obtains your dental records, instructs an independent dental expert to review the treatment and give an opinion on breach of duty and causation, then sends a formal Letter of Claim to the dentist or practice (and their indemnity insurer). Most cases that are supported by a positive expert report settle through negotiation, often within 12 to 18 months; only a small minority proceed to a court hearing.

Frequently asked questions

How much compensation can you get for dental negligence in the UK?

General damages for dental negligence typically range from around £1,000 for a minor, easily corrected issue up to £105,190 or more for severe, permanent damage requiring major reconstruction, based on published Judicial College Guidelines bands. The cost of corrective private treatment and any lost earnings are usually added on top. Every case is valued individually.

Can I claim if my dentist extracted the wrong tooth?

Yes. Extracting the wrong tooth is a well-recognised form of dental negligence, provided you can show the extraction was avoidable and fell below the standard expected of a reasonably competent dentist. You will usually need your dental records and an independent dental expert's opinion to support the claim.

What if my NHS dentist missed my gum disease?

A missed or delayed diagnosis of periodontal (gum) disease can be negligent if a reasonably competent dentist should have identified it from your check-up, X-rays or symptoms and referred or treated you sooner. If the delay caused avoidable bone loss or tooth loss, this can form the basis of a claim regardless of whether the treatment was NHS or private.

What is the time limit for a dental negligence claim?

Generally three years from the date of the negligent treatment, or three years from the date you first knew (or reasonably should have known) that your ongoing problem was linked to it. For children, the three-year period starts on their 18th birthday.

Do I need an independent dental expert?

In almost all cases, yes. Dental negligence claims require an independent dentist to review your records and treatment and give an opinion on whether the standard of care fell below what was reasonably expected, and whether this caused your loss. Your solicitor will usually arrange this as part of the claims process.

Will pursuing a claim affect my future dental treatment?

No. You are entitled to bring a claim without it affecting your right to further NHS or private dental care, and most claims are handled through correspondence between solicitors and the dentist's indemnity insurer rather than directly with the practice.

Is there a no-win-no-fee option for dental negligence claims?

Yes, most dental negligence solicitors offer Conditional Fee Agreements (no-win-no-fee), meaning you pay nothing upfront and no legal fees at all if your claim is unsuccessful. If successful, the solicitor takes an agreed success fee, typically capped at 25% of your general damages.
