Most of us put a great deal of trust in our dentist. So when a routine filling leaves you with numbness that will not go away, a tooth is pulled that should not have been, or gum disease goes unnoticed until it is too late to save your teeth, it can feel like a real betrayal, as well as being painful, expensive and upsetting.

A dental negligence claim may be possible when a dentist's care falls below the standard expected and that failure causes you harm. Not every bad outcome is negligence, though, and knowing the difference is the first step.

This guide explains what counts as dental negligence, the most common types of claim, how compensation is worked out, and how the claims process works, including time limits and funding. Our medical negligence solicitors handle claims against both NHS and private dentists, so we have written it with the questions our clients ask most in mind.

What counts as dental negligence?

Dental negligence happens when a dentist, hygienist, orthodontist or oral surgeon provides care that falls below the standard expected of a reasonably competent professional in their field, and that failure causes you injury that would otherwise have been avoided.

The key word is avoidable. Dentistry, like all medicine, carries risks. A tooth can fracture during extraction, or an implant can fail, even when everything is done correctly. That is a complication, not negligence. A claim arises where the problem was caused by an error that a competent dentist would not have made, such as poor technique, a missed diagnosis or treatment carried out without proper consent.

Consent matters more than many people realise. Since the Supreme Court's decision in Montgomery in 2015, clinicians must explain the material risks of a treatment and any reasonable alternatives. If you were not told about a significant risk, and you would have chosen differently had you known, that can be grounds for a claim even if the treatment itself was carried out competently.

Common types of dental negligence claim

One of the most frequent claims involves undiagnosed gum disease (periodontal disease). If a dentist fails to spot or treat it over a number of check-ups, it can progress to the point where teeth loosen and have to be removed. Similarly, failing to notice the signs of oral cancer, or to refer a patient promptly, can have devastating consequences. Delays like these are a form of misdiagnosis.

Nerve damage is another serious category. The lingual and inferior alveolar nerves run close to the lower wisdom teeth, and poor planning or technique during extraction, implants or injections can damage them, leaving lasting numbness, tingling or pain in the tongue, lip or chin.

Other common claims involve extracting the wrong tooth, root canal treatment that is incomplete or leaves instruments behind, poorly fitted crowns and bridges, failed implants placed without adequate bone assessment, and orthodontic treatment that damages teeth or roots. Cosmetic work such as veneers can also go wrong, particularly where healthy teeth are filed down unnecessarily; our cosmetic negligence team handles these claims too.

What you need to prove

To succeed, you must prove two things. The first is breach of duty: that the care fell below an acceptable standard. The courts apply what is known as the Bolam test, asking whether a responsible body of dental professionals would have acted in the same way. Independent expert evidence from an experienced dentist is used to answer this.

The second is causation: that the substandard care caused your injury, or made it worse, rather than an underlying condition that would have caused the same harm anyway. This is often the more difficult part, particularly in gum disease cases, where the expert has to consider how much tooth loss would have been prevented by earlier treatment.

Your dental records, X-rays and treatment notes are central to both. You have a right to request copies, and your solicitor will usually obtain them for you.

What is a dental negligence claim worth?

Every claim is valued individually, but compensation is made up of two parts.

General damages compensate you for the pain, suffering and loss of amenity (the impact on your everyday life) caused by the negligence. Solicitors and courts use the Judicial College Guidelines, which set out brackets for different injuries; the latest edition was published in April 2026. The guidelines distinguish between front and back teeth and between damage to one tooth and several, and permanent nerve damage or the consequences of a delayed cancer diagnosis are valued much more highly. Claims for the loss of several front teeth, for instance, are worth considerably more than the loss of a single back tooth.

Special damages reimburse your financial losses. In dental cases, the largest item is often the cost of corrective treatment, which can be substantial where implants, bridges or extensive restorative work are needed, sometimes over many years. You can also claim for lost earnings, travel to appointments, medication and any other expenses caused by the negligence.

Because the cost of future treatment can be significant, a dental negligence claim is often worth more than people expect. Your solicitor will obtain expert evidence on the treatment you need now and in the future so that it is fully reflected in the claim.

Time limits for dental negligence claims

Under the Limitation Act 1980, you generally have three years to start court proceedings. The three years run either from the date of the negligent treatment or from the date you first knew, or reasonably should have known, that you had suffered harm because of it. This later "date of knowledge" is important in dental cases, where problems such as gum disease may only become apparent years later.

For children, the three years do not start until their 18th birthday. For someone who lacks the mental capacity to manage a claim, the time limit may not run at all. Even so, it is best to seek advice as early as possible, because evidence is easier to gather while it is fresh.

How the claims process works

A dental negligence claim usually follows these stages:

1. A free initial discussion with a solicitor about what happened.
2. Your solicitor obtains your dental records and X-rays.
3. An independent dental expert reviews the records and reports on breach of duty and causation.
4. A formal Letter of Claim is sent to the dentist under the court's pre-action protocol for clinical disputes, and they have time to investigate and respond.
5. Your solicitor negotiates a settlement, or issues court proceedings if the claim cannot be agreed.

Most dental claims settle without going to a trial. If you were treated by a high street NHS dentist, the claim is normally brought against the dentist personally and handled by their professional indemnity provider. If you were treated in a hospital dental department, the claim is brought against the NHS trust, and our hospital negligence solicitors can help.

You can also complain about your care through the practice or the NHS complaints procedure. A complaint can give you an explanation and an apology, but it will not result in compensation, so many people pursue both.

Funding your claim

Most dental negligence claims are funded through a conditional fee agreement, commonly known as no win, no fee. If your claim is unsuccessful, you do not pay your solicitor's fees. If it succeeds, a success fee is deducted from your compensation, and by law this is capped at 25% of your damages for pain and suffering and past losses. Your solicitor should explain exactly what you could pay before you sign anything.

Insurance is usually arranged to cover the cost of expert reports and other expenses if the claim does not succeed, so you are not left out of pocket.

Frequently asked questions

Can I claim against an NHS dentist?

Yes. You can bring a dental negligence claim against an NHS or private dentist. High street NHS dentists are usually covered by their own professional indemnity, so the claim is brought against the dentist rather than the NHS itself.

How long do I have to make a dental negligence claim?

Usually three years from the date of the negligent treatment, or from the date you first realised you had been harmed by it. For children, the three years start on their 18th birthday.

How much compensation could I get for dental negligence?

It depends on the injury and its impact. Compensation covers pain and suffering, valued using the Judicial College Guidelines, plus financial losses such as the cost of corrective treatment, which is often the largest part of a dental claim.

Is nerve damage after a tooth extraction negligence?

Not always, because nerve injury is a known risk of some extractions. It may be negligence if the procedure was poorly planned or carried out, or if you were not warned about the risk before agreeing to treatment.

Do I need to complain to my dentist before making a claim?

No. You can make a claim without complaining first, although a complaint can provide useful information. A complaint alone will not result in compensation.

Conclusion

Dental negligence covers a wide range of problems, from missed gum disease to nerve damage and failed implants. What they have in common is avoidable harm caused by care that fell below an acceptable standard. A successful claim can cover both the pain you have been through and the cost of putting things right.

Time limits apply, and expert evidence is key, so it pays to take advice early. A specialist dental negligence solicitor can review what happened and explain your options clearly.
