GDC Suspension: What Happens and How Dentists Return to Practice

What Is GDC Suspension?

GDC suspension is a formal sanction imposed by a GDC practice committee after a full GDC fitness to practise hearing where the committee finds that a dentist's fitness to practise is currently impaired and that conditions of practice would not be sufficient to protect patients or public confidence in the dental profession.

During GDC suspension, the dentist is removed from the dental register. They cannot treat patients, work in any dental capacity, or call themselves a dentist or dental care professional. Practising while suspended is a criminal offence under the Dentists Act 1984 and can result in prosecution as well as a referral for erasure.

GDC suspension is not a finding that the dentist is permanently unfit to practise — it is a protective measure combined with an opportunity for the dentist to demonstrate genuine insight and remediation. Whether the dentist returns to practice depends entirely on what they do during the suspension period and how well they prepare for the mandatory review hearing.

Interim Suspension Versus Substantive Suspension

There are two distinct types of GDC suspension, and dentists must understand the difference between them. In 2025 the Court of Appeal in GDC v Aga [2025] EWCA Civ 68 confirmed that these are two separate, consecutive orders that cannot be combined or aggregated.

• Interim suspension — imposed by the Interim Orders Committee before a full fitness to practise hearing, as an urgent protective measure while the investigation proceeds. Lasts up to 18 months with six-monthly reviews. Not a finding of guilt or impairment. The dentist can continue to challenge the interim order at each review
• Substantive suspension — imposed by the Professional Conduct Committee after a full hearing where fitness to practise has been found to be impaired. Lasts up to 12 months under section 27B of the Dentists Act 1984. The time spent under interim suspension cannot be deducted from the substantive suspension period
• Immediate suspension — imposed by the practice committee at the conclusion of a hearing to protect the public during the 28-day appeal window before the substantive order takes effect. Also a separate order under section 30 of the Dentists Act 1984

What Triggers GDC Suspension?

GDC suspension is imposed when the practice committee concludes that a dentist's fitness to practise is impaired and conditions of practice would be inadequate. Common triggers include serious or persistent clinical failures, dishonesty or confidentiality breaches, sexual misconduct, criminal convictions, boundary violations, and cases where the dentist has not demonstrated sufficient insight or engagement with remediation at the hearing stage.

The practice committee considers suspension — rather than the less serious sanction of conditions of practice — where the conduct was serious, where there is evidence of a pattern rather than a one-off error, or where the dentist poses a continuing risk to patients. The committee applies the least restrictive sanction that adequately protects the public, so dentists who demonstrate strong insight and early remediation at the hearing stage may avoid suspension altogether.

• Serious clinical failures — repeated substandard treatment, inadequate record keeping, failure to obtain informed consent
• Probity and honesty concerns — dishonesty with patients, employers, the GDC, or NHS bodies
• Sexual misconduct — boundary violations involving patients or dental team members, which the GDC's January 2026 guidance treats with heightened seriousness
• Criminal convictions — particularly those involving violence, dishonesty, or conduct affecting public trust
• Insufficient insight — where the dentist has not demonstrated genuine understanding of the impact of their conduct at the hearing

How Long Does GDC Suspension Last?

A substantive GDC suspension can last for any period the practice committee considers appropriate, up to a maximum of 12 months at any single hearing. At the review hearing before the suspension expires, the committee can revoke the suspension, replace it with conditions, extend it for a further period, or refer the case for a fresh hearing at which erasure may be considered.

In cases where the committee considers that erasure would be disproportionate but the dentist is not yet fit to return to unrestricted practice, the GDC can extend suspension beyond 12 months through consecutive suspension orders. The GDC's online register reflects the current status of a dentist's registration throughout, making it visible to employers, NHS commissioners, and the public.

What Happens at a GDC Suspension Review Hearing?

The GDC suspension review hearing is the critical stage at which a practice committee decides whether a dentist's fitness to practise remains impaired. The committee reviews all evidence submitted by the dentist and any evidence from the GDC, and the dentist or their legal representative can make submissions and call witnesses.

The review committee is not bound by the original sanction and can impose any outcome it considers appropriate based on the current evidence. The possible outcomes at a GDC suspension review hearing are as follows:

1. Revocation of suspension — the committee is satisfied that fitness to practise is no longer impaired. The dentist returns to unrestricted practice immediately
2. Replacement with conditions — suspension is lifted but the dentist must comply with conditions of practice for up to 36 months, with further reviews
3. Extension of suspension — the committee is not yet satisfied with the level of remediation and extends the suspension for a further period
4. Referral for a fresh hearing — in the most serious cases, the committee refers the case to a fresh panel where erasure may be considered

The key question the review committee asks is whether the remediation undertaken is sufficient, genuine, and sustainable — and whether the dentist poses any continuing risk to patients or public confidence.

How to Prepare for a GDC Suspension Review Hearing

Preparation for the GDC suspension review hearing must begin from the very first day of the suspension period. Dentists who arrive at the review hearing with a strong, documented remediation portfolio consistently achieve better outcomes than those who prepare only in the final weeks.

1. Engage your defence organisation and legal representative — contact Dental Protection, the BDA, MDDUS, or a specialist regulatory solicitor at the outset. Do not attend a review hearing unrepresented
2. Complete targeted CPD — address the specific concerns raised at the original hearing with relevant CPD courses, including ethics, probity, and any clinical areas identified as deficient
3. Write a detailed reflective statement — demonstrating that you understand what went wrong, why it was serious, how it affected patients and public trust, and what you have done to ensure it cannot happen again
4. Obtain character references and supervisor reports — from clinical colleagues, supervisors, and where applicable from any supervised practice undertaken during the suspension
5. Produce a personal development plan — showing the committee how you intend to maintain standards and continue your professional development after returning to practice
6. Attend all hearings and comply with all GDC directions — non-attendance or non-compliance is treated seriously and can result in extension or escalation of the suspension

The dentists who return to practice after GDC suspension are those who treat the suspension period as a structured opportunity to rebuild — not as downtime to wait out. Every course completed, every reflection written, and every reference obtained strengthens the case at the review hearing.

Appealing a GDC Suspension

A dentist who disagrees with a GDC suspension can appeal to the High Court in England and Wales within 28 days of being notified of the decision. An appeal must be based on legal grounds — such as an error of law, procedural unfairness during the hearing, or a sanction that is disproportionate to the findings of fact.

The Professional Standards Authority for Health and Social Care can also refer a GDC sanction to the High Court if it considers that the sanction imposed was insufficient to protect the public. This means that even a sanction of conditions — rather than suspension — can be challenged upwards by the PSA.

Appeals are complex and should always be pursued with specialist legal representation. Attempting a High Court appeal without a regulatory solicitor carries significant risk of costs and adverse findings. Contact your defence organisation without delay if you are considering an appeal against GDC suspension.

International Dentists and Cross-Border Practice

GDC suspension is recorded on the public dental register and can be shared with overseas regulators under information-sharing agreements. For dentists who have trained or practised in multiple countries, a GDC suspension can affect registration with overseas regulatory bodies. UK dentists who also hold overseas registration should notify the relevant overseas regulator as required under their own rules and seek advice from that regulator's equivalent of a defence organisation.

For UK-registered dentists looking to strengthen their understanding of professional ethics and regulatory obligations, Healthcare Ethics Courses provides training aligned with GDC standards and UK professional obligations. Dentists working across New Zealand and the UK can find similar ethics training for New Zealand dentists a useful reference for cross-jurisdictional practice. Those with connections to Australia may find equivalent professional development for dentists in Australia helpful for understanding how professional standards operate across both countries.
