Dental Consent Forms (UK): When You Need One and What to Record

Consent failures are a frequent basis for dental negligence claims in the UK. Not because clinicians forget to ask permission — but because the documentation does not demonstrate what was discussed, what risks were disclosed, or what the patient actually agreed to. Since the Montgomery v Lanarkshire ruling in 2015, the legal standard for consent has shifted from what a reasonable clinician would disclose to what a reasonable patient would want to know. A signed consent form alone no longer protects you — the record behind it must show a genuine, informed conversation.

This guide sets out what makes consent valid in law, a 7-point checklist for documenting it, what Montgomery changed, when written consent forms are required versus when verbal consent is sufficient, the most common consent documentation failures, and how to structure consent records for different treatment types. For a broader look at consent as part of clinical documentation, see our dental consent documentation guide.

Montgomery v Lanarkshire: what changed for dentists

Montgomery v Lanarkshire (2015) replaced the old Bolam test — what a reasonable clinician would disclose — with a patient-centred standard: every material risk (one a reasonable person in the patient’s position would be likely to attach significance to, or that you know or should know this particular patient would) and any reasonable alternative or variant treatments, named specifically rather than described as a generic “risks explained” (para 87). For the full Montgomery/Bolam explanation and the material risks to disclose by procedure, see our dental consent documentation guide.

A 7-point consent documentation checklist

Valid consent is not a signature on a form. In law, consent is valid when the patient has capacity, gives it voluntarily and has been given enough information. Since Montgomery, that includes the material risks and any reasonable alternatives. The checklist below is Nosht’s way of making sure your record shows each of those things. A record that misses an item doesn’t automatically make consent invalid, but it makes it much harder to show that consent was valid if it is challenged.

GDC Principle 3 — “Obtain valid consent” — is the regulatory framework that underpins these elements. Standard 3.1.1 requires you to make sure you have valid consent before starting treatment and not to assume a colleague has obtained it; 3.1.2 says you should document the consent discussion; and 3.3 treats consent as an ongoing process, with specific consent for each appointment in a course of treatment (3.3.2). For multi-visit procedures (root canal treatment, implant placement), consent should be confirmed at each appointment.

Written vs verbal consent: when each is appropriate

There is a persistent misconception that written consent is always legally superior to verbal consent. This is not the case. What matters is not the form of consent but the quality of the documented discussion behind it. A signed consent form with no documented discussion is weaker than a detailed verbal consent note that records exactly what was discussed, what risks were disclosed, and what the patient decided.

When verbal consent is sufficient

For routine, non-surgical procedures with well-understood risks, verbal consent documented in the clinical record is generally accepted as sufficient. This includes:

• Simple restorations (fillings)
• Scale and polish
• Fissure sealants
• Fluoride varnish application
• Simple impressions
• Recall examinations
• Radiographs (with documented justification under IR(ME)R)

Even for these procedures, the clinical record must document that the patient was informed about what the procedure involves and consented to proceed. For any procedure where there are identifiable material risks (which, in practice, includes most treatments), the specific risks discussed should be recorded.

When written consent is required or recommended

Written consent is mandatory for conscious sedation and general anaesthetic (GDC Standard 3.1.6). Dental defence organisations also commonly advise written consent forms for procedures carrying significant or irreversible risks:

• Surgical extractions — including impacted third molars, teeth with proximity to the IAN canal, and any extraction with an elevated risk of complications
• Dental implant placement — and all associated procedures (sinus lifts, bone grafts, guided bone regeneration)
• Sedation and general anaesthetic — required (GDC 3.1.6): intravenous and inhalation sedation, and general anaesthetic, need separate written consent covering sedation-specific risks
• Orthodontic treatment — fixed appliances, clear aligners, and any orthodontic intervention with a prolonged treatment plan
• Elective cosmetic procedures — veneers, composite bonding, whitening, smile makeovers where aesthetic expectations must be managed
• Surgical endodontics — apicoectomy, root-end resection
• Periodontal surgery — flap procedures, crown lengthening, regenerative surgery
• Any procedure with a risk of permanent nerve damage

Critical point: A signed consent form is not a substitute for a clinical record entry. The form captures the signature; the clinical record must capture the discussion. Both are needed for full protection. A signed form without a documented discussion can be challenged on the basis that the patient signed without understanding.

Common consent documentation failures

Consent documentation failures recur: generic phrases such as “consent obtained” or “risks explained” with no specifics named, missing alternatives, and consent recorded against a whole “treatment plan” rather than the specific procedure performed that visit. For the full list drawn from GDC fitness to practise outcomes and dental defence case reports, see our dental consent documentation guide.

Consent template guidance by treatment type

The content of your consent documentation should be tailored to the specific procedure. Below is guidance on what a consent record should include for common dental treatments.

Extraction consent record

Root canal treatment consent record

Implant consent record

Digital consent documentation: the advantages

Digital consent documentation has significant advantages over paper-based consent forms, particularly in the context of regulatory scrutiny and dento-legal defence:

• Audit trails — digital systems record when entries were created and modified, providing contemporaneity evidence that paper records cannot match. This works in your favour when records are created at the time of the appointment.
• Structured prompts prevent omissions — digital templates can prompt for each element of consent (risks, alternatives, patient decision), reducing the chance that any element is missed.
• Legibility — digital records eliminate handwriting legibility issues that can undermine paper-based consent documentation.
• Accessibility and retrieval — digital records can be retrieved instantly when needed for a complaint, claim, or GDC request. Paper consent forms stored in filing cabinets can be lost, misfiled, or deteriorate over time.
• Integration with clinical notes — digital consent documentation sits within the same record as the clinical notes, treatment plan, and post-operative instructions, creating a complete, coherent record.

The transition from paper consent forms to digital documentation is straightforward. The legal requirements are the same — what changes is the medium, not the content. Whether consent is recorded on paper or digitally, the checklist items should be recorded.

GDC principle 3: obtain valid consent

GDC Principle 3 (“Obtain valid consent”) is the regulatory foundation behind the checklist above — it requires the options discussed, the patient’s understanding confirmed, and consent reconfirmed at each stage of treatment. For the full breakdown of what Principle 3 requires, see our dental consent documentation guide.

How Nosht structures consent documentation

As a dental notes app, Nosht builds consent documentation into every treatment template, so the consent record is a natural output of the note-writing workflow rather than an afterthought:

• Treatment-specific risk fields — each template includes material risks tailored to that procedure. Extraction templates prompt for nerve damage, dry socket, oroantral communication. Root canal templates prompt for instrument separation, perforation, post-operative flare-up. You select the risks discussed rather than trying to remember and type them.
• Alternatives prompts built in — every treatment template prompts for alternative treatment options, including no treatment.
• Patient decision recording — structured fields capture the patient’s decision, whether consent was verbal or written, and whether a consent form was signed.
• Bulletproof Mode for consent completeness — Bulletproof Mode checks the structured fields of your note against record-keeping rules drawn from UK guidance (FGDP(UK)/CGDent, GDC, NICE, SDCEP and others) as you write, and flags missing items before you copy the note. It is on by default for higher-stakes templates such as extractions, sedation and implants, and you can switch it on for any other template. It checks what is recorded, not the quality of the care. Bulletproof flags missing risk, alternatives and consent-decision fields.
• Patient information leaflets — Nosht includes 68 free patient information leaflets — post-op care instructions, treatment guides, and condition explanations — that you can email directly to patients with one click (sending a leaflet uses the patient's email address or mobile number; you remain the data controller). Providing a written leaflet alongside your verbal consent discussion creates additional evidence that the patient received information in a format they could review at home.
• One-click copy to any PMS — the complete consent record, including risks, alternatives, and patient decision, is copied as plain text into your practice management system alongside the clinical note.

The result is consent documentation structured to the Montgomery standard, produced as part of your standard workflow — not something that requires extra time, extra effort, or a separate consent form workflow. Get started from £9.99/month.
