Background Longitudinal studies of dental prescribing in Australia show that dentists make some inappropriate prescribing choices; literature has shown that dentists tend to overprescribe antibiotics and prescribe for incorrect indications. The unnecessary use of antibiotics is a contributing factor towards the development of antibiotic resistance. The aims of the study were to obtain a greater understanding of the perceptions, attitudes and factors that influence dental prescribing for all major relevant drug classes. Method Semi‐structured interviews of 15 purposively sampled dentists practising in Victoria, Australia were conducted from June–September 2018. Two dentists practised in rural areas and the remainder in urban locations. The range of clinical experience varied from 2.5 to 37 years, with a mean of 13 years. The transcripts were analysed thematically. Results Dentists generally preferred amoxicillin as first‐line therapy for odontogenic infections, with some confusion about the spectrum and uses of antibiotics. Overprescribing was evident, mostly due to basing judgement for use of antibiotics on symptoms rather than clinical signs. Other factors, such as time pressure, patient expectations, pressure from assistant staff, concern about online criticism and medico‐legal considerations, influenced prescribing. Of the dentists who prescribed anxiolytics, most did not have a care protocol for their sedated patients. Conclusion A variety of prescribing practices were described, and future interventions should target misconceptions around the appropriate use and choice of antibiotics, resources to address the shortfall in knowledge of therapeutics, patient education and staff training, as well as appropriate care and monitoring of sedated patients.
