Stigma of addiction and mental illness in healthcare: The case of patients' experiences in dental settings.

When associated with stigma, mental illness and addictions have negative implications for accessing health and dental care. From our participants' perspectives, it seems that the lack of understanding about their life conditions by the healthcare professionals was the origin of stigma. We suggest that an increased social awareness of these health issues be enhanced among current and future health and dental care professionals to help improve care experiences for this marginalized population.
