Continuing professional development (CPD) is essential for maintaining competence and ensuring high standards in the dental profession. The General Dental Council (GDC) in the UK currently emphasises formal learning within its CPD framework. However, this article argues that informal learning - particularly through hybrid social learning networks - plays a vital role in the ongoing professional development of dental practitioners. Drawing on key studies, including Stanfield (2024), Bullock et al. (2023) and Cowpe et al. (2019), as well as the work of Evans (2019) and Greenhow and Lewin (2016), this article explores the significance of informal learning and how it complements formal CPD.Informal learning, driven by peer-to-peer interaction, online networks and reflective practice, allows dental professionals to acquire real-time, context-specific knowledge, bridging the gap between theoretical learning and clinical application. This form of learning promotes lifelong professional growth and helps practitioners remain agile in adapting to technological advances. Moreover, informal learning is cost-effective and accessible, offering a practical solution for overcoming barriers to traditional CPD, such as time and financial constraints.Recognising informal learning within the GDC's CPD framework would create a more flexible, inclusive and effective system of professional development. Recommendations include incorporating reflective practice, developing mechanisms to validate informal learning and promoting the use of digital platforms for CPD.By acknowledging the value of informal learning, the GDC can ensure that dental professionals are not merely complying with CPD requirements but are actively engaged in a continuous process of improvement, better prepared to meet the evolving demands of the profession.
