You are entitled to understand what treatment will cost before you agree to it, and a written estimate is the practical way that happens. That is the whole idea behind informed financial consent in dentistry. It sits alongside clinical consent, which is your right to understand the treatment itself, and it is meant to happen before anything starts rather than at the front desk afterwards. What it does not mean is a guaranteed figure for every appointment, and understanding that difference is what keeps the conversation useful instead of adversarial.
Key takeaways
- Informed financial consent means you understand the likely cost, and what could change it, in time to make a decision.
- The Australian Dental Association's Policy Statement 5.16 on informed financial consent, last reviewed and approved by the ADA Board on 27 June 2025 with the next review due in June 2030, sets out what the profession expects.
- Clause 2.4 recognises that fees may be itemised or time based, so a dentist may only be able to estimate a range rather than give a precise binding quote.
- Clause 3.3 describes a written quotation with recorded acceptance as good business practice that results in fewer disputes and fewer bad debts. That is best practice, not a black letter legal requirement before every appointment.
- The AHPRA shared Code of Conduct, applied to dentists through the Dental Board of Australia, separately requires practitioners to discuss costs appropriately and reach general agreement about the level of treatment and its cost, preferably before treatment.
- Contacting your own health fund to confirm cover and benefits is your responsibility, not the practice's.
What informed financial consent actually means
Informed financial consent means you have been told what treatment is proposed, what it is likely to cost and what could change that figure, early enough to make a real decision. Clause 2.1 of the Australian Dental Association's Policy Statement 5.16 frames it as part of sound ethical professional practice rather than as a piece of administration, which is a useful way to think about it. The paperwork is evidence of the conversation, not a replacement for it.
Clause 2.10 adds something patients rarely hear about: the practitioner should take reasonable steps to confirm that the patient has adequately understood the estimated cost. That is not the same as handing someone a printed sheet on the way out. In my experience the moment that matters is when a patient says the number back, or asks what happens if the tooth turns out to need more work. If nobody checked whether the figure landed, the consent process was incomplete even when the file looks tidy.
Why your dentist often cannot give you one fixed number
Because dental fees can be itemised or time based, and because the inside of a tooth is not fully visible until treatment starts. Clause 2.4 of Policy Statement 5.16 acknowledges this directly: the dentist may only be able to estimate a range of fees. A precise binding quote is not always possible, and a practice that promises one for complex work is over-promising rather than being generous.
Clause 2.5 sets out what should be said alongside the number. Any estimate given before treatment should include advice that the estimate is not guaranteed and that the cost may increase if the procedure takes longer than expected or if other procedures turn out to be required. The classic example is decay under an existing filling, which only becomes visible once the old material is removed. A tooth planned for a straightforward restoration can turn out to need more, and the honest version of that conversation happens beforehand, not afterwards.
This is why larger items such as crowns and implants are usually presented as staged plans with review points rather than as one figure agreed on the spot. Staging the plan gives both sides a place to pause and reconsider before the next step is committed to.
What a proper written estimate should include
A useful written estimate does far more than name a total. It lists the procedures with their item numbers, states plainly that the figure is an estimate, names what could change it, and says how long it stands. Clause 3.3 of Policy Statement 5.16 describes providing a written quotation of fees and recording the patient's acceptance before treatment as good business practice that results in fewer disputes and fewer bad debts. Read that as the profession's best practice standard rather than as a legal requirement attached to every visit.
| Element | Why it matters | Who is responsible for confirming it |
|---|---|---|
| An itemised list of procedures with item numbers | Lets you see exactly what is planned and look up the benefit payable for each item | The practice supplies the numbers; you check them with your fund |
| A statement that the figure is an estimate and not a guarantee | Reflects clause 2.5 and sets expectations honestly before anything begins | The practice, in the wording of the document itself |
| What could change the figure, such as extra procedures, longer treatment or findings under an existing filling | These are the realistic causes of a higher final account, and naming them removes the surprise | The practice should list them; ask directly if they are missing |
| Ongoing maintenance and review costs | Clause 2.11 treats future maintenance as part of the ethical obligation, and it is the part most often left out | The practice, prompted by you asking about the long term |
| How long the estimate is valid | Fees, materials and laboratory costs change, and an open-ended figure invites a dispute later | The practice, on the face of the estimate |
| Your health fund benefit for those item numbers | This is what decides your actual out of pocket amount, not the fee alone | You. Confirming your own cover is your responsibility, not the practice's |
Item numbers belong on the estimate
Clause 2.6 of Policy Statement 5.16 is explicit: where charging is based on an itemised schedule, the patient should be given the relevant item numbers so that the patient can confirm the applicable health fund benefit or government rebate. Asking for the codes is not an awkward or suspicious request. It is the process working as the profession's own policy says it should.
Item numbers matter because they are the only language you, the practice and your fund all share. A fund will not assess a claim from a description such as a big filling on a back tooth. It assesses the code. Without the numbers you cannot get a straight answer about your benefit, which means you cannot work out your gap, which means the estimate is only half an estimate. Our guide to reading a dental treatment plan covers what else that document should set out alongside the codes.
Confirming your fund benefit is your job, not the practice's
This is the point most people get wrong, and Policy Statement 5.16 addresses it plainly at clause 3.6 and again in its position summary: patients, not dentists, are responsible for contacting their own health fund to confirm actual cover and benefits.
The reason is not that practices are unwilling to help. It is that only your fund can see your product, your remaining annual limit, your waiting periods and any network arrangement that applies to you. A practice can quote its fee and hand you the item numbers. It cannot see inside your policy, and a rebate figure guessed at the front desk is not something you should rely on. If a practice does give you an indicative rebate, treat it as a courtesy and confirm it with your fund before treatment. If the remaining amount is more than you expected, our article on ways to spread the cost of dental treatment covers the usual options.
Where the obligation actually comes from
Three separate sources sit behind this, and they are often muddled together. Keeping them apart tells you what you can insist on and what is simply good practice.
The Australian Dental Association's policy
Policy Statement 5.16 is the profession's own member facing policy. It is detailed and it is the best description of what good looks like, but it is an association policy rather than legislation. When a practice follows it closely, that is a fair sign of how it runs.
The AHPRA shared Code of Conduct
The shared Code of Conduct, which applies to registered dental practitioners through the Dental Board of Australia, requires practitioners to discuss costs appropriately and to obtain general agreement about the level of treatment and its cost, preferably before treatment. This is a professional conduct obligation enforced through AHPRA and the Dental Board, and it is distinct from the association's policy. Being honest about the limits of what could be verified here: whether that particular clause is independently actionable on its own, separate from a broader conduct complaint, was not something we could confirm.
Australian Consumer Law
Under Australian Consumer Law generally, statements a business makes about price must be accurate and not misleading. Following the general guidance the ACCC gives businesses, a binding quote should be clear about what it covers and how long it is valid, and a non binding estimate should be clearly labelled as indicative. Worth saying plainly: no dentistry specific enforcement action on misleading dental estimates was found, so these are general principles applied by analogy rather than settled dental case law. It is also worth knowing that quote and estimate are not separately defined and regulated terms in Australian dental regulation. The distinction is a practical and general consumer law one, which is exactly why the wording on the document you are given matters so much.
Maintenance and review costs are part of the conversation
Clause 2.11 of Policy Statement 5.16 treats future maintenance costs as part of the ethical obligation, and it is the element most often missing from an estimate. A figure that covers only the day of treatment is incomplete for anything with a long life ahead of it.
Crowns, implants, dentures and orthodontic retainers all need review, cleaning and occasional repair or replacement over the years. None of that is a hidden cost or a sign of failure. It is the ordinary upkeep of restored teeth, and it should be raised while you are still deciding, because it can change which option makes sense. It is also the other half of an argument covered in our piece on what putting off dental care tends to lead to: cost avoided now often reappears later as something larger.
If the final account is much higher than the estimate
Ask for an itemised account first, then compare it line by line against the estimate you were given. Most disputes turn out to be a small number of added item numbers that were never explained, and an explanation resolves them.
- Ask which items were added, and why they became necessary during treatment.
- Ask for that explanation in writing, alongside the itemised account.
- Check whether the additions were among the possibilities named in the original estimate.
- If the answer is not satisfying, a second opinion is a reasonable step, particularly before further treatment is booked.
- If the concern is about professional conduct, it can be raised with AHPRA, and in New South Wales with the Health Care Complaints Commission.
- If a significant sum or a signed agreement is involved, get advice from a solicitor or a financial counsellor.
Common questions
Does my dentist have to give me a written quote before treatment?
A written quotation before treatment is described by the Australian Dental Association's Policy Statement 5.16 as good business practice, not as a universal legal requirement for every appointment. Separately, the AHPRA shared Code of Conduct requires costs to be discussed and general agreement reached about treatment and cost, preferably beforehand. In practice, asking for it in writing is entirely reasonable and most practices will provide one.
What is the difference between a dental estimate and a dental quote?
In everyday use, a quote is a firm figure for defined work and an estimate is an indicative figure that may move. That distinction comes from general consumer law and ordinary business practice rather than from dental regulation, where the two words are not separately defined. What matters is how your document is labelled and what it says about what could change.
Can my dentist charge me more than the estimate?
Yes, where the treatment actually required turns out to be different from what was planned. Clause 2.5 of Policy Statement 5.16 anticipates exactly this, which is why an estimate should say the figure is not guaranteed and that cost may increase if the procedure takes longer or if other procedures are needed. Changes of that kind should be explained to you, ideally before they are carried out.
Is verbal cost consent enough?
A discussion can satisfy the requirement to talk about cost, and for a single simple item it often does. The problem with a verbal figure is evidence: neither side can check it later. Clause 3.3 points to written quotations with recorded acceptance precisely because they lead to fewer disputes, so for anything beyond routine work, ask for it in writing.
What should be included in a treatment plan estimate?
An itemised list of procedures with item numbers, a clear statement that the figure is an estimate, the specific things that could change it, any maintenance or review costs to expect afterwards, and how long the estimate stands. Your health fund benefit for those item numbers is the last piece, and that one is yours to confirm.
What can I do if the final bill was much higher than the estimate?
Start with the practice: request an itemised account and a written explanation of any items that were added. If that does not resolve it, a conduct concern can be raised with AHPRA, and in New South Wales with the Health Care Complaints Commission. For a disputed amount or a signed agreement, speak to a solicitor or a financial counsellor rather than relying on general information.
Ask for it in writing before you say yes
Nobody should be agreeing to dental treatment without knowing what it is likely to cost and what could change that. The team at Lumi Dental in Melrose Park provides written estimates with item numbers before treatment begins, so you can check your own benefit with your fund and decide with real information in front of you. If you are booking in for the first time, have a look at what is currently available on our current offers page, or get in touch and ask for an estimate for the treatment you are considering.
This article is general information only. It is not legal or financial advice, and it is not a substitute for advice about your own circumstances, your own policy or your own teeth. Policies, professional guidance and benefits change and vary, so confirm cover with your own health fund. For a concern about a registered practitioner, contact AHPRA, or in New South Wales the Health Care Complaints Commission. For a disputed account or a signed agreement, speak to a solicitor or a financial counsellor.
