Background Oral health problems affect approximately one in five aged care residents. While training Residential Aged Care (RAC) staff in oral health care may improve resident outcomes, uptake of available training in Australia remains unclear. Furthermore, there is a lack of recent studies examining oral health care practices and training among Australian RAC staff. Methods A qualitative study was undertaken to explore current oral health care practices and training in RAC. Semi‑structured individual interviews were conducted with RAC staff in Queensland and New South Wales (n=16), Australia, with data analysed using inductive content analysis. Results Participants reported having minimal to no oral health care training and limited awareness of available training. They reported “learning on the job”, “winging” oral health care, and having minimal confidence providing oral health care. Perceived barriers to oral health care included difficulty in caring for residents who have cognitive impairment or changed behaviours and lack of access to required equipment (e.g., light, tongue depressors, dental mirrors). Potential implementation strategies suggested by participants included embedding oral health assessments within “Resident of the day” and providing regular (e.g., annual) training on oral health care. Conclusions Limited training contributes to RAC staff’s reduced confidence and perceived lack of ability to provide oral health care. Training should address the provision of oral health care to residents with cognitive impairment and changed behaviours. Future studies should incorporate implementation strategies informed by RAC staff to potentially increase the uptake of training and improve adoption of oral health care into practice.
