Informed Consent in Australian Dental Practice
Consent is one of the most common themes in dental complaints — and one of the most misunderstood. This guide explains what valid informed consent requires in Australian dentistry, when written consent is needed, how much to disclose, and why informed financial consent matters as much as clinical consent.
Key takeaways
- Valid consent needs capacity, adequate information and a voluntary decision — it is a process, not a signature.
- Routine care is usually covered by verbal consent; written consent is warranted for complex, invasive, sedation, high-cost or cosmetic treatment.
- Patients must be told about material risks, in plain language suited to their understanding.
- Informed financial consent — costs, payment and funding implications — is part of valid consent.
- Cosmetic and elective care calls for extra time, realistic expectations and careful documentation.
What informed consent means
Consent is not a signature — it is a process. For consent to be valid the patient must have capacity to decide, be given adequate information about the proposed treatment, its risks, benefits, alternatives and costs, and make the decision voluntarily, free from coercion. The Dental Board’s shared Code of conduct (Section 3.5) sets this out, supported by the ADA’s Guidelines for Consent for Care in Dentistry.
Implied, verbal and written consent
By attending and sitting in the chair, a patient impliedly consents to an initial examination — but nothing more. Most routine treatment is covered by verbal consent after a proper discussion. Written consent is warranted where treatment is complex or invasive, involves sedation or anaesthesia, carries significant expense, or is elective or cosmetic. A signed form is evidence, not proof: it supports a valid consent process but does not replace it.
How much to disclose
Patients should be told about material risks — those a reasonable person in the patient’s position would consider significant, and any risk this particular patient would attach importance to. Explanations should be in plain language, free of jargon, and pitched to the individual’s understanding. If the patient cannot understand the explanation, that is the practitioner’s responsibility to remedy.
Informed financial consent
Cost is part of consent. Patients should understand the fee for each option, how it is paid, what happens if treatment is not completed, and the implications of third-party or credit arrangements. Be especially careful with buy-now-pay-later schemes and superannuation-release funding, which can push patients toward treatment they cannot sustain.
Cosmetic and elective care
Where the lines between clinical need and cosmetic preference blur, the Board urges particular care: give patients adequate time to consider, set realistic expectations, and obtain full informed — including financial — consent. Document the options presented (including the option of no treatment or referral) and the risks and benefits discussed. If a consent dispute becomes a complaint, our guide to Dental Board complaints explains what follows; strong records are your best protection.

Complaints Explained Dental Record Keeping and DocumentationFrequently asked questions
Is a signed consent form enough?
No. A signed form is useful evidence but does not prove valid consent. What matters is a documented discussion of the options, risks, benefits and costs, and the patient's voluntary agreement.
When is written consent required in dentistry?
Good practice warrants written consent for treatment that is complex or invasive, involves sedation or anaesthesia, carries significant expense, or is elective or cosmetic.
What risks do I have to disclose?
Material risks — those a reasonable person in the patient's position would consider significant, plus any risk this particular patient would attach importance to.
What is informed financial consent?
Ensuring the patient understands the cost of each treatment option, how it is paid, and the implications of funding arrangements such as buy-now-pay-later or superannuation release, before treatment proceeds.
Do cosmetic procedures need extra care?
Yes. The Board urges adequate time to consider, realistic expectations, and full informed and financial consent, with the discussion documented.
