Abstract: This study assessed links between racism and oral health outcomes among pregnant Canadian Aboriginal women. Baseline data were analyzed for 541 First Nations (94.6%) and Métis (5.4%) women in an early childhood caries preventive trial conducted in urban and on- reserve communities in Ontario and Manitoba. One- third of participants experienced racism in the past year determined by the Measure of Indigenous Racism Experience. In logistic regressions, outcomes significantly associated with incidents of racism included: wearing dentures, off- reserve dental care, asked to pay for dental services, perceived need for preventive care, flossing more than once daily, having fewer than 21 natural teeth, fear of going to dentist, never received orthodontic treatment and perceived impact of oral conditions on quality of life. In the context of dental care, racism experienced by Aboriginal women can be a barrier to accessing services. Programs and policies should address racism’s insidious effects on both mothers’ and children’s oral health outcomes. Key words: Racism, discrimination, oral health, dental services accessibility, dental care disparities, Aboriginal peoples, pregnant women.
