How to Complain About a Dentist in the UK: NHS, Private and GDC Routes
Start with the practice, in writing, within 12 months. After that, NHS complaints go to the NHS and an ombudsman, private ones to the free Dental Complaints Service, and serious safety concerns to the GDC.
If you want to know how to complain about a dentist in the UK, start with the practice itself, in writing, within 12 months of the treatment. If that doesn't settle it, the next step depends on whether your care was NHS or private: NHS complaints go to the NHS body for your area and then an ombudsman, while private complaints go to the free Dental Complaints Service.
There's a third route, the General Dental Council, but it's for serious concerns about a dentist's fitness to practise, not for getting your money back. Picking the wrong route can cost you weeks, so spend five minutes working out which one fits before you write anything.
If you're in pain or swelling now, deal with that first
A complaint can wait a week. An infection can't. If your problem started after treatment and you have any of the following, get care before you think about complaining:
- Call 999 or go to A&E if swelling in your mouth, face or neck is making it hard to breathe, swallow or open your eye, or if bleeding won't stop.
- Call NHS 111 or ask for an urgent dental appointment if you have severe pain that painkillers don't touch, swelling that is getting bigger, or bleeding or pain after an extraction.
You don't have to go back to the dentist you're unhappy with for urgent care. Our guide on how to find an NHS dentist covers getting seen elsewhere, including urgent appointments.
First, work out whether your care was NHS or private
This sounds obvious until you look at your receipt. Many practices offer both, and the GDC points out that a single appointment can include NHS and private treatment. A check-up might be NHS while the white filling or hygienist visit added on was private.
Look at your treatment plan or ask the practice to confirm in writing. If the treatment was paid for through a dental plan or insurance scheme, contact the plan provider too, because it may have its own complaints process.
| Your situation | Where to go first | If it isn't resolved | What it can achieve |
|---|---|---|---|
| NHS treatment in England | The practice, or your integrated care board (ICB) | Parliamentary and Health Service Ombudsman | An explanation, apology, remedy or recommendation |
| Private treatment anywhere in the UK | The practice | Dental Complaints Service | Mediation towards a refund, remedial treatment or apology |
| Serious risk to patients, NHS or private | General Dental Council | Fitness to practise process | Conditions, suspension or removal from the register |
| You want compensation for harm | The practice first | A solicitor or Citizens Advice | A legal claim, separate from complaints |
How to complain to the practice so it gets taken seriously
Every NHS practice must have a complaints procedure, and private practices are expected to have one too. Ask for it. Address your complaint to the practice manager, and where you can, name the dentist who treated you.
Put it in writing, even if you've already said it at the desk. Email is fine. A good complaint letter is short and boring, which is exactly why it works:
- Your name, date of birth and the dates of the appointments involved.
- What happened, in order, with facts rather than adjectives.
- What effect it has had on you, such as pain, extra appointments or time off work.
- What you want: an explanation, an apology, the work redone, a refund, or a mix.
- A request for a written reply.
Keep copies of everything, including your treatment plan, receipts and any photos. If you want your clinical notes to support the complaint, you can ask for them, and the practice can't refuse because you're complaining.
The 12-month limit runs from the treatment, or from when you first realised there was a problem. The NHS website applies the same limit to NHS and private complaints, so don't sit on it.
How to complain about an NHS dentist in England
You have a choice at the start. You can complain to the practice, or, if you'd rather not deal with them directly, to your local integrated care board. ICBs are responsible for NHS dental services in England, so they can investigate a practice's NHS work. You can't do both at once for the same complaint, so pick one.
If the practice or ICB has given its final response and you're still unhappy, you can take it to the Parliamentary and Health Service Ombudsman, on 0345 015 4033 or online. The ombudsman makes final decisions on NHS complaints in England, but it won't look at yours until the local process has finished. That's why the written final response matters: it's your ticket to the next stage.
It's not a long shot. The ombudsman reported in 2023 that it upheld or partly upheld 78% of the dental complaints it investigated in 2022/23, against 60% for other NHS services.
Be realistic about what the ombudsman does. It decides whether the NHS service got things wrong and whether that was put right. It can recommend an apology, a remedy or changes to practice. It isn't a court, and most people who use it are after an acknowledgement that something went wrong rather than a payout.
If writing letters to the NHS feels like too much, you don't have to do it alone. Free NHS complaints advocacy is available in England, and Healthwatch can tell you who provides it locally.
Complaining about a private dentist: the Dental Complaints Service
Private dentistry has no ombudsman. What it has is the Dental Complaints Service, which is run by the GDC, free, impartial and covers private dental care across the UK. You can reach it on 020 8253 0800, Monday to Friday, 9am to 5pm.
The service works by mediation. It talks to you and the dental professional and tries to reach an outcome you both accept, which can be a refund, remedial treatment or an apology. It can't force a dentist to pay you, it can't give legal advice, and it doesn't handle NHS treatment.
Contact the practice first. The NHS guidance treats the DCS as the step after the practice manager has had a fair chance to put things right, and a written record of that attempt will help your case.
If mediation fails and you want to recover money, the GDC points private patients to a solicitor or Citizens Advice. A legal claim is a separate process with its own time limits, so take advice early if you're heading that way.
When to report a dentist to the GDC instead
The General Dental Council registers dentists, dental nurses, hygienists, therapists and technicians. It can restrict, suspend or remove someone's registration. What it can't do, in its own words, is resolve complaints or help with refunds.
That makes it the right route when the issue is about risk rather than redress. Examples include a dentist working while clearly unwell or impaired, treating patients without consent, serious and repeated clinical failings, dishonesty, or someone practising who isn't registered at all. If the problem is a filling that failed and a bill you think is unfair, the GDC is the wrong door.
You can report to the GDC and complain to the practice at the same time. They are separate processes with different aims.
Complaints in Wales, Scotland and Northern Ireland
The first step is the same everywhere: raise it with the practice. After that, the NHS route changes by nation.
- Wales: NHS complaints follow the Putting Things Right process. You can go to the practice or your local health board, then to the Public Services Ombudsman for Wales.
- Scotland: Complain to the practice or your NHS board, then to the Scottish Public Services Ombudsman.
- Northern Ireland: Health and social care complaints go to the practice first, then to the Northern Ireland Public Services Ombudsman. The Patient and Client Council offers free support.
Private complaints in all three go to the Dental Complaints Service, and serious concerns about a professional go to the GDC, which covers the whole UK.
What the CQC and online reviews can and can't do
The CQC inspects dental practices in England, but it doesn't settle individual disputes. Telling it about your experience still counts, because feedback helps it decide when and where to inspect. It won't get you a refund or an apology.
A review is different again. It doesn't resolve anything for you, but it's often the only place the next patient will hear about it. On Rated Clinics, reviews need a verified email address, a booking confirmation or receipt earns a "Verified visit" badge, and we moderate every review before it goes up. Our page on how we verify reviews and clinics sets out the rules, and our review policy says what we publish and remove.
If you do write one, stick to what happened and how it was handled. A review that says "the practice replied within a week, apologised and redid the crown" is as useful to other patients as a critical one. Our guide to finding trustworthy reviews shows what readers look for.
Dentist complaints in the UK: common questions
How long do I have to complain about a dentist?
Usually 12 months from the treatment or from when you realised there was a problem. That applies to NHS and private care. Complain as soon as you can, because memories and records are clearer early on.
Can I complain about an NHS dentist without going to the practice?
Yes. In England you can complain to your local integrated care board instead. In Wales and Scotland, the health board can take the complaint.
Will the GDC get me a refund?
No. The GDC says it can't resolve complaints or help with refunds. For private treatment, the Dental Complaints Service can help you negotiate one, and for NHS care, the practice or ICB can offer a remedy.
Is the Dental Complaints Service free?
Yes, it's free for patients and covers private dental treatment across the UK. It doesn't handle NHS care.
Can my dentist stop treating me because I complained?
A complaint on its own shouldn't be a reason to end your care, and the NHS says making a complaint should not affect your future treatment. If you think it has, mention it in your complaint or to whoever is handling it next.
Should I leave a review as well as complaining?
You can, and many people wait until the complaint is finished so they can say how it was handled. Keep it factual and leave out other people's names and health details.
Had a dentist handle a problem well, or badly? Write a review of a clinic you've used so the next patient knows.
