Background: People with mental health disorders are reported to have poorer access to dental services and poorer oral health outcomes. The aim of this paper is to analyze current published work regarding barriers and enablers for oral health outcomes and access to dental care for adults with mental health disorders which will be addressed from individual, organizational and systemic perspectives Methods: A narrative review based on a search of the relevant published work regarding oral health for people with mental health disorders was undertaken using Medline, Web of Science, ERIC and Psychlit. Any relevant systematic reviews were highlighted in this process along with primary studies. Results: The published work repeatedly verified poorer oral health and inadequate access to dental services in people with mental health disorders. The published work identified barriers at individual, organizational and systemic levels. Much of the published work focused on barriers with less focus on enablers and interventions. Conclusions: Considerable investigation of barriers had not elucidated options to improve care or outcomes.
