Substance use disorders are a risk factor for poor oral health which in turn impacts quality of life. Resultant oral problems contribute to chronic illness, premature mortality, social stigma, embarrassment and reduced opportunities for employment and social interaction. Providing dental services to people with substance use disorders is often difficult due to high rates of oral disease, anxiety, behavioural and drug use changes, and lifestyle factors. Previous studies have demonstrated that alcohol and other drug service clients find accessing and navigating oral health services complex and suggest a multidisciplinary care approach to improve outcomes. In this commentary, we describe individual and structural barriers that limit the use of oral health care among people with substance use disorders, alcohol and other drug clinicians' challenges to integrating oral health into their practice and identify key issues for oral health services in delivering care. We draw on our experience to recommend a multidisciplinary approach be used to develop strategies in order to increase access to oral health services at a standard similar to the general population for clients of alcohol and other drug services.
