How a practice handles a complaint often matters more than the complaint itself. Done well, it resolves the issue, protects the practice and generates learning; done badly, it escalates a solvable problem into a regulatory or legal one. This guide sets out how to handle private dental complaints correctly — the routes, the obligations, and the mindset that keeps complaints from becoming something worse.

Every practice must have a complaints procedure

This is not optional. Both NHS and private dental practices are required to have a clear, accessible complaints procedure, and in England having an effective system for handling complaints is part of the CQC’s fundamental standards — it is something an inspection will look at. Beyond the rulebook, a working complaints procedure is one of the most useful management tools a practice has: it surfaces problems while they are still fixable.

Private and NHS complaints follow different routes

The single most important structural point is that the escalation route depends on how the patient was treated. If your practice provides both NHS and private care, you need to handle both correctly.

Private complaints

For private treatment, the patient should raise the complaint with the practice first, and most complaints are resolved there. If it cannot be resolved locally, the patient can take it to the Dental Complaints Service (DCS) — a free, impartial service for private dental care, funded by the GDC and operating across the UK. The DCS works to broker a resolution between patient and practice; it does not award compensation. Beyond the DCS, a patient’s remaining route is legal advice (for example a negligence claim through a solicitor).

NHS complaints

For NHS treatment, the patient can complain either to the practice or to the relevant NHS commissioner, and if the complaint cannot be resolved that way it can ultimately be escalated to the Parliamentary and Health Service Ombudsman. The NHS complaints regulations also set expectations on timing — including acknowledging a complaint within three working days — which are worth building into your process even for private complaints as good practice.

Where the GDC fits — and where it does not

Patients sometimes assume the GDC resolves complaints. It does not: the GDC regulates professionals and does not get involved in complaints being managed locally, nor does it award compensation. Its interest begins only where a concern is serious enough to raise a question about a professional’s fitness to practise — which is a different process with a much higher threshold (see our guide to the GDC fitness-to-practise process). Handling a complaint well and early is, among other things, the best way to stop a resolvable problem from ever reaching that threshold.

TWO ROUTES, AND ONE DEAD END
The escalation route forks on how the patient was treated — and the GDC is on neither branch.
Where a dental complaint can be escalated, and why the General Dental Council is not on either routeA flow diagram of complaint escalation, forking on whether the treatment was private or NHS. Every complaint starts the same way: every practice, NHS and private, must have a clear, accessible complaints procedure, and in England handling complaints effectively is part of the CQC’s fundamental standards. Acknowledge within three working days, which the NHS complaints regulations require and which is good practice for private complaints too. The route then depends on how the patient was treated. On the private side, the patient should raise it with the practice first. On the NHS side, the patient may go either to the practice or to the NHS commissioner. Both lead to local resolution, drawn as the heaviest path because most complaints end there: acknowledge quickly and without defensiveness, investigate fairly, explain what you found and apologise where appropriate, noting that an apology is not an admission of liability; record it, review for patterns and feed the learning back, which is the well-led evidence an inspector wants. If it cannot be resolved locally the routes diverge. A private complaint goes to the Dental Complaints Service, which is free and impartial, funded by the GDC and covering private dental care across the UK; it brokers a resolution between patient and practice and does not award compensation. Beyond that the patient’s remaining route is legal advice, for example a negligence claim through a solicitor. An NHS complaint goes instead to the Parliamentary and Health Service Ombudsman, the final stage where the practice or commissioner could not resolve it. Separately, and marked in gold as not a complaints route, the General Dental Council sits off both paths, reached only by a struck-through connector. Patients often assume the GDC resolves complaints. It does not: it regulates professionals, does not get involved in a complaint being managed locally, and awards no compensation. Its interest begins only where a concern raises a question about a registrant’s fitness to practise, a separate process with a much higher threshold. Handling a complaint well and early is the best way to stop a resolvable problem ever reaching it. Finally, involve your indemnity provider the moment a complaint is serious, hints at a claim, or alleges clinical harm.A patient complainsEvery practice needs a written, accessible procedure.Acknowledge within three working days.NHS regulations require it; good practice privately.The route depends on how the patient was treatedPRIVATE TREATMENTNHS TREATMENTRaise it with the practiceThe patient comes to you first.The practice or the commissionerEither one, for NHS treatment.Resolved locally — where most complaints endAcknowledge fast, investigate fairly, log it, review for patterns.If it cannot be resolved locallyDental Complaints ServiceFree, impartial, GDC-funded.

Line weight shows where the traffic goes, not how much of it: the path into local resolution is drawn heaviest because most complaints end there. No volumes are implied. The private route runs one stage further than the NHS route, and the NHS route has two entry points where the private route has one.Source: compiled by The Reliance from the routes set out in this guide.

How to handle a complaint well

The mechanics matter less than the approach, but a sound process looks broadly like this:

  • Acknowledge quickly and take it seriously. A prompt, non-defensive acknowledgement de-escalates more complaints than anything else. Aim to acknowledge within a few working days.
  • Investigate fairly. Establish what actually happened from the records and the people involved, before forming a view.
  • Respond clearly. Explain what you found, what you will do, and — where appropriate — apologise. An apology is not an admission of liability, and the duty of candour expects openness when something has gone wrong.
  • Tell the patient their onward options. Signpost the DCS (private) or the relevant NHS route if they remain dissatisfied — withholding this erodes trust and looks evasive.
  • Record and learn. Keep a complaints log, review complaints for patterns, and feed the learning back into the practice. This is exactly the “well-led” evidence an inspector wants to see.
  • Involve your indemnity provider where a complaint is serious, hints at a claim, or alleges clinical harm — early advice protects everyone.
What this means for your practice

What this means for your practice. Make sure you have a written complaints procedure that patients can find, that your team knows how to respond in the first 24–48 hours, and that you correctly signpost the Dental Complaints Service for private patients and the NHS route for NHS patients. Keep a complaints log and review it — both because the CQC expects it and because complaints are free intelligence about where your practice is leaking trust. Handle them early and openly, and involve your indemnity provider the moment a complaint looks serious.
