How to make a complaint about dental treatment in NSW

The right body to take a complaint about dental treatment NSW patients want resolved depends entirely on what you want out of it, and the body most people contact first cannot get them a refund. The NSW Health Care Complaints Commission states plainly on its own frequently asked questions page that it is not able to order a provider to pay compensation, to issue a refund, or to reduce a fee. So if money is the point, the Commission is the wrong door. If safe practice is the point, it is the right one. Working out which of those you are chasing is the most useful thing you can do before you write a word.

Key takeaways

  • Raise the problem with the practice first. Most complaints are resolved there, and the regulators expect you to have tried.
  • The Health Care Complaints Commission cannot order compensation, issue a refund, or reduce a bill. It says so on its own page, and it directs refund requests to the Office of Fair Trading.
  • NSW uses a co-regulatory model. The HCCC and the Dental Council of New South Wales jointly manage complaints about a dentist's conduct, performance or health.
  • Registration sits nationally with the Dental Board of Australia through AHPRA, and anyone can check a dentist on the public national register.
  • Money questions go elsewhere: the Office of Fair Trading on 13 32 20 for refunds, the Private Health Insurance Ombudsman on 1800 640 695 for health fund issues, and Medicare Australia on 13 20 11 for item number concerns.
  • Complaints to the HCCC must be in writing, are allocated to an Assessment Officer, and the Commission aims to assess them within 60 days.

Start with the practice, because most complaints end there

The first move is almost always to put your concern to the practice in writing and give it a fair chance to respond. Practices can do things no regulator can: refit a crown, redo a filling, adjust a denture, explain a decision, apologise, or choose to waive or refund a fee. Regulators cannot order most of that, and they generally want to see that you have raised the matter locally first.

Keep it short and factual. Say what treatment you had and when, what went wrong or what you did not expect, and what you would like to happen. Attach your itemised account or the written treatment plan. Ask for a reply by a set date, and send it by email so you have a dated record.

If you were never clear on what was proposed, read our guide to reading a dental treatment plan first, because many complaints turn out to be a gap in explanation rather than a gap in care. A calm second opinion can also tell you whether the work was below standard or simply different from what you pictured.

Decide what you actually want before you decide who to contact

Every complaint sorts into one of four things, and which one you pick decides your route. An explanation, a clinical fix, money back, and action about the practitioner are four different jobs handled by four different sets of people.

You want an explanation

Ask the practice directly, and ask in writing. You are entitled to understand what was done and why. If the answer does not satisfy you, a second dentist reviewing your records and radiographs will usually give a clearer picture than a regulator would, and faster.

You want the clinical problem fixed

Only a dentist can do that. Either the original practice offers to redo the work or you have it done elsewhere. Regulators do not provide treatment and cannot direct a practice to redo yours.

You want money back

This is the route people most often get wrong. Refunds are a consumer matter, and compensation for harm is a legal matter that needs a solicitor. Neither the HCCC nor AHPRA can deliver either one.

You want action taken about the practitioner

That is what the health complaints system is built for. In NSW the HCCC and the Dental Council of New South Wales handle conduct, performance and health concerns about registered dentists, focused on protecting the public rather than settling your grievance.

What each body cannot do

Start here: the Health Care Complaints Commission states on its own page that it is not able to order providers to pay compensation, to issue a refund, or to reduce fees. If you are seeking compensation, the Commission advises you to obtain legal advice. If you are seeking a refund, it directs you to the Office of Fair Trading. That single fact reshapes most people's plan.

The Commission also states that government does not regulate the fees charged by private health providers, dentists included, and that it is unable to assist with complaints about fees or to help people obtain refunds, compensation, or changes to a bill. Dental fees in NSW are not capped or set by any authority.

AHPRA and the Dental Board of Australia sit in the same position on money. A notification to AHPRA is a risk based process: it asks whether the practitioner poses an ongoing risk to the public, not whether you were treated fairly as a customer. Outcomes range from no further action through to conditions on registration, suspension or tribunal referral. None of those puts money back in your account.

There is also no single one stop body. A billing dispute, a clinical concern and a privacy concern from the same appointment can end up with three different organisations, which is normal rather than a sign you have gone wrong.

The table below sets out who does what.

Who regulates dentists in NSW, and why NSW is different

NSW runs a co-regulatory model, which most national guides skip. The Health Care Complaints Commission and the Dental Council of New South Wales jointly manage complaints and notifications about the conduct, performance or health of dental practitioners in NSW. In other states a notification is handled within the national scheme through AHPRA. In NSW it lands in a shared system, which is why you may hear from two organisations about one complaint.

The Dental Council of New South Wales

The Council, supported by the Health Professional Councils Authority, generally handles lower level conduct, performance and health matters: a practitioner whose record keeping has slipped, or whose own health is affecting their practice. It can manage those through conditions and structured programs designed to bring practice back up to standard.

The Commission

More serious matters may be investigated by the HCCC and, where warranted, prosecuted. The Commission and the Council consult on each matter, so the two are not competing pathways. You lodge once and the system sorts it.

AHPRA and the Dental Board of Australia

Registration itself is national. Whether a person is a registered dentist, and any conditions attached to that registration, sits with the Dental Board of Australia through AHPRA. Anyone can search the public national register free of charge, which is a sensible check before booking. For a NSW registered dentist, a conduct notification is usually dealt with under the co-regulatory arrangement described above.

Fees, bills and refunds sit outside the health complaints system

Money complaints have their own set of doors, and the HCCC names them. For concerns about private health insurance benefits or cover, it points to the Private Health Insurance Ombudsman on 1800 640 695. That function now sits inside the Office of the Commonwealth Ombudsman, though both names remain in live official use, including on the Commission's own page, so do not be thrown if you see one name and not the other. For refunds, the Commission points to the Office of Fair Trading on 13 32 20. For concerns about overservicing or the misuse of item numbers, it points to Medicare Australia on 13 20 11.

A common source of frustration is the assumption that dentistry ought to be funded the way a visit to a doctor is. It generally is not, and the reasons are structural rather than local. Our explainer on why dental care is not bulk billed in Australia covers that history, and knowing it helps you frame a fee complaint realistically. If the size of the bill took you by surprise, your strongest evidence is the written treatment plan and itemised quote you were given beforehand.

Consent, capacity and the age rules

A complaint about consent is a clinical complaint, and the HCCC can investigate where valid consent was allegedly not obtained. On the same page, the Commission sets out what valid consent requires: the person must have capacity, must understand the risks, benefits and alternatives, must be informed about fees, and must be consenting voluntarily rather than under pressure.

The fee element surprises people. Being told what something is likely to cost is part of consent, not an optional courtesy.

Age has its own rules. Under 14, a child is generally taken to lack capacity to consent to their own treatment, and a parent or guardian consents on their behalf. From 14, a young person may be assessed as capable of consenting. From 16, a young person's own consent is generally treated as sufficient. That matters for families where a teenager attends an appointment alone.

In my experience a rushed consent discussion is often a nervous one. If that sounds familiar, our guide to managing fear of the dentist has practical ways to slow an appointment down and ask for what you need.

Your records and your privacy: an honest grey area

This is one area where the official guidance does not line up neatly, and it is fairer to say so than to pick a side. The HCCC's own page directs people with privacy concerns to the NSW Information and Privacy Commission. The Office of the Australian Information Commissioner, meanwhile, takes the position that all private health service providers must comply with the federal Privacy Act 1988, because health information is not covered by the small business exemption that applies to other small operators.

In practice a NSW dental practice may be answerable federally, while the state referral pathway still exists and is still published. The sensible approach is to raise it with the practice first, then contact whichever of the two bodies you can reach and ask them to confirm they are the right body or redirect you.

Access to your own records is a separate matter and usually easier than people expect. Our guide to transferring records and radiographs to a new dentist sets out how to request them.

How an HCCC complaint runs

Complaints to the Commission must be made in writing. Each is allocated to an Assessment Officer, and the Commission aims to assess complaints within 60 days. Assessment is not investigation. It is the stage where the Commission decides what happens next, which may include resolution, referral to the Dental Council of New South Wales, a formal investigation, or discontinuation.

If you disagree with the decision, you can request a review in writing within 28 days of the decision letter. If your concern is with the way the Commission itself handled your complaint rather than with the outcome, that goes to the NSW Ombudsman. Concerns about discrimination go to the NSW Anti-Discrimination Board.

Two protections are worth knowing. A complaint made in good faith cannot expose you to legal action for making it, and knowingly making false allegations to the Commission is an offence, so write what you can support.

You can complain anonymously, but it is harder for the Commission to assess an anonymous complaint. It generally needs to seek a response from the provider, and to do that it must tell them the nature of the complaint and generally who made it.

On time limits, be careful with what you read online. A commonly repeated figure circulates on secondary sites and could not be confirmed against the Commission's own material, so ask the Commission directly how long you have rather than letting an unverified number talk you out of lodging.

Common questions

Can the Health Care Complaints Commission get me a refund from my dentist?

No. The Commission states that it is not able to order providers to pay compensation, issue a refund, or reduce fees. It directs refund requests to the Office of Fair Trading on 13 32 20 and advises obtaining legal advice if you are seeking compensation.

What is the difference between the HCCC and AHPRA for a dental complaint?

AHPRA administers national registration for the Dental Board of Australia and receives notifications about risk to the public. The HCCC is the NSW health complaints body and works jointly with the Dental Council of New South Wales, so a conduct complaint about a NSW dentist is usually handled through that co-regulatory arrangement.

How long do I have to make a complaint about a dentist in NSW?

Check directly with the Commission rather than relying on a number found online. A commonly quoted time limit appears only in secondary sources and could not be confirmed against official material. Sooner is better regardless, because records and memories are easier to work with.

What does the Dental Council of NSW actually do?

It works with the HCCC under the NSW co-regulatory model and generally handles lower level conduct, performance and health matters about registered dental practitioners, managing them through conditions or programs aimed at bringing practice back up to standard. It does not award compensation or order refunds.

Who do I complain to if I think my dentist overcharged me?

Raise it with the practice and ask for an itemised account. If that does not resolve it, the HCCC points to the Office of Fair Trading on 13 32 20 for refunds, the Private Health Insurance Ombudsman on 1800 640 695 for health fund issues, and Medicare Australia on 13 20 11 for overservicing or item number concerns. Private dental fees are not regulated.

Can I complain to more than one body at once?

Yes, and often you should. One appointment can raise a clinical concern, a billing dispute and a privacy concern, handled by different organisations. Mention in each complaint who else you have contacted so they can coordinate.

What happens after I lodge a complaint with the HCCC?

It is allocated to an Assessment Officer and the Commission aims to assess it within 60 days. It may seek your consent to obtain your records and will generally seek a response from the practitioner. You will receive a decision letter, and you can request a review in writing within 28 days if you disagree.

If what you really want is a straight answer about your teeth

Sometimes what a person needs is not a regulator but a clear look at what is going on in their mouth. The team at Lumi Dental in Melrose Park can review earlier work, take a fresh set of records, and explain what we see in plain language, including when the previous treatment looks reasonable.

New patients can see the current offer on our current deals page, or get in touch with a question first. A written quote is provided before treatment starts.

This article is general information only and is not legal or financial advice. It does not take account of your circumstances, and complaint pathways and contact numbers can change. For advice about your own situation, contact the relevant body or speak with a solicitor, and speak with a registered dental practitioner about your own treatment.
