This guide sets out the legal framework — parental responsibility, Gillick competence, and the rules that apply once a young person turns 16 — alongside our general guide to informed consent in orthodontics.

Only one person with parental responsibility needs to consent, in principle, but UK orthodontic practices generally look for agreement from those with day-to-day care of the child, and will pause treatment if it becomes clear that parents actively disagree about whether it should proceed. Step-parents, grandparents and other carers do not automatically have parental responsibility unless it has been formally granted, so a practice will usually confirm who is entitled to consent before starting a long course of treatment such as fixed braces. ## Gillick competence and consent by a child under 16 In UK law, a child under 16 can sometimes consent to their own medical or dental treatment without a parent, if the treating clinician judges them to have sufficient maturity and understanding to appreciate what is involved — a test known as Gillick competence, taken from the 1985 House of Lords case Gillick v West Norfolk and Wisbech Area Health Authority. The related Fraser guidelines were set out in the same case specifically for contraceptive advice and are sometimes referenced more broadly, but the underlying Gillick competence test is the one generally applied across children's healthcare, orthodontics included. In practice, a clinician assessing Gillick competence for something as significant as a multi-year course of fixed-appliance treatment is applying a high bar, and the great majority of UK orthodontic providers will still involve a parent or guardian in the consent conversation for patients under 16, even where the child could arguably consent alone, because doing so better supports a long treatment course that depends on sustained parental involvement — attending appointments, funding treatment, and supporting oral hygiene and appliance care at home. ## Consent at 16 and 17 Young people aged 16 and 17 are presumed by law to have the capacity to consent to their own medical and dental treatment, under the Family Law Reform Act 1969. This means a 16- or 17-year-old can, in principle, agree to orthodontic treatment without a parent's separate consent. The exception is where the young person is assessed as lacking capacity to make the decision — for example, because of a cognitive impairment — in which case the Mental Capacity Act 2005 framework for assessing capacity and, if needed, making decisions in a person's best interests applies instead. As with under-16s, most UK practices continue to involve parents in the consent discussion for 16- and 17-year-olds as a matter of good practice and because parental support typically remains central to a long course of treatment, even though this is not a strict legal requirement at this age. ## What consent for a child's orthodontic treatment should cover The substance of what needs to be explained before treatment begins does not change because the patient is a child — a parent or Gillick-competent young person is entitled to the same standard of information as an adult patient: the diagnosis, the proposed treatment and its alternatives (including no treatment), the realistic expected outcome, the material risks (including relapse without a retainer, and the possibility that extractions may be needed), and the retainer commitment after treatment finishes. Our general guide to informed consent, linked below, sets out this substantive standard — including the 2015 Montgomery ruling and GDC Standard 3 — in full; this page focuses specifically on who is legally entitled to give that consent when the patient is a minor. ## Involving the child in the conversation, even where a parent consents Good clinical practice, reflected in GDC guidance, is to explain treatment to a child at a level they can understand and involve them in the decision wherever possible, even when the legal consent is being given by a parent. A child who does not want fixed braces, or who is anxious about a specific part of treatment, is not simply overridden because a parent has signed a form — compliance-dependent treatments such as removable appliances, headgear or clear aligners in particular tend to fail without the child's genuine buy-in, so most orthodontists will treat a reluctant child as a signal to pause and address concerns rather than proceed on parental consent alone. ## Withdrawing consent mid-treatment for a minor A parent (or a Gillick-competent young person, or a 16- or 17-year-old) can withdraw consent to ongoing treatment at any point, in the same way an adult patient can. If a parent wishes to stop a child's treatment, they should inform the practice, which will typically arrange an appointment to remove any fixed appliances safely and assess current dental health. For NHS treatment, withdrawing before completion means the course is recorded as incomplete and there is no refund of the Band 3 charge already paid. Our general consent guide covers the financial and clinical implications of withdrawal in more detail. ## Consent for photographs and data use involving a child Clinical photographs and X-rays are a standard part of orthodontic records for children as for adults, and the same parental or Gillick-competent consent rules apply to taking and storing them as clinical data. A separate and distinct consent is required if a practice wants to use a child's photographs for marketing purposes — for example, before-and-after images on a website or social media — and this should never be assumed from consent to clinical treatment. A parent (or Gillick-competent young person) should be asked specifically and separately, told exactly how and where the images will be used, and given a genuine option to decline without it affecting treatment. You are entitled to withdraw marketing consent at any time even if you originally agreed. ## Useful related pages [What Counts as Informed Consent for Braces?](https://virtualconsultant.online/guides/orthodontic-consent-patient-rights-uk) [Getting a Second Opinion UK](https://virtualconsultant.online/guides/second-opinion-orthodontist-uk) [What Is an Orthodontist UK](https://virtualconsultant.online/guides/what-is-an-orthodontist-uk) [NHS Orthodontic Complaints UK](https://virtualconsultant.online/guides/nhs-orthodontic-complaints-uk) [Get a Virtual Consultation](https://virtualconsultant.online/evaluations/quote) This guide is for general information only.

Normally a parent or person with parental responsibility, for a child under 16. A child under 16 can sometimes consent themselves if the treating clinician assesses them as Gillick competent — having sufficient maturity and understanding of what is involved. In practice, most UK orthodontic providers involve a parent in the conversation regardless, because sustained parental support matters for a multi-year treatment course. What is Gillick competence? Gillick competence is the legal test, from the 1985 case Gillick v West Norfolk and Wisbech Area Health Authority, used to decide whether a child under 16 has enough maturity and understanding to consent to their own medical or dental treatment without a parent. It is assessed by the treating clinician for the specific decision in question, not as a general label that applies to a child in every situation. Can a 16 or 17 year old consent to orthodontic treatment without a parent? Yes, in principle. Under the Family Law Reform Act 1969, 16- and 17-year-olds are presumed to have the legal capacity to consent to their own medical and dental treatment. Most practices still involve parents in the consent conversation as good practice, given that parental support is usually important to a long course of treatment, but this is not a strict legal requirement at this age. Does a parent's consent override a child's wishes about braces? Legally, a parent's consent for a child under 16 is what makes treatment lawful, but good clinical practice means explaining treatment to the child directly and taking their views seriously. A child who is genuinely unwilling is a real problem for treatments that depend on cooperation — such as removable appliances or clear aligners — so most orthodontists treat a reluctant child as a reason to pause rather than proceed regardless. Do I need to give separate consent for my child's photos to be used for marketing? Yes. Consent to take clinical photographs as part of your child's treatment records is separate from consent to use those photographs for marketing, such as before-and-after images on a website. A practice should ask specifically and separately for marketing consent, explain how images will be used, and let you decline without affecting treatment. You can withdraw marketing consent at any time. What if my child's other parent disagrees with starting orthodontic treatment? Only one person with parental responsibility needs to consent in principle, but most UK practices will pause and seek to resolve clear disagreement between parents before starting a long course of treatment, since ongoing conflict can disrupt attendance, funding and appliance care throughout treatment. Discuss the situation directly with the practice. Explore your options Quick links Not sure where to start?
