The General Dental Council (GDC) requires dental practitioners to provide good-quality care based on current evidence and authoritative guidance . However, this leaves the dental practitioner in a sort of limbo as good quality is an ill-defined term allowing its precise meaning to be open to interpretation . This article sets out to demonstrate that the practice of dentistry is very much more of an art than a science and, as such, relies on individual skill and judgement . It will also show that the 'value' of current evidence as determined by published papers and authoritative guidance is questionable and should not be regarded by dental practitioners as the 'rule' . The interaction between a dentist and a patient essentially consists of clinical decision-making and the implementation of that decision and, therefore, it is essential to understand the nature of decision-making and the context in which implementation takes place . Practitioners should exercise their clinical judgement, putting the interests of the patient first and not feel constrained by the threat of sanctions from the GDC or other regulatory bodies.
