There are important calls for greater inclusion of Indigenous and racialised communities in oral microbiome research. This paper uses the concept of racial capitalism (the extractive continuity of colonialism) to critically examine this inclusion agenda. Racial capitalism explicitly links capitalist exploitations with wider social oppressions e.g., racisms, sexism, ableism. It is not confined to the commercial sector but pervades white institutions, including universities. By using the lens of racial capitalism, we find inclusion agendas allow white institutions to extract social and economic value from relations of race. Racially inclusive research is perceived as a social good, therefore, it attracts funding. Knowledge and treatments developed from research create immense value for universities and pharmaceutical companies with limited benefits for the communities themselves. Moreover, microbiome research tends to drift from conceptualisations that recognise it as something that is shaped by the social, including racisms, to one that is determined genetically and biologically. This location of problems within racialised bodies reinforces racial oppressions and allows companies to further profit from raciality. Inclusion in oral microbiome research must consider ways to mitigate racial capitalism. Researchers can be less extractive by using an anti-racism praxis framework. This includes working with communities to co-design studies, create safer spaces, giving marginalised communities the power to set and frame agendas, sharing research knowledges and treatments through accessible knowledge distributions, open publications, and open health technologies. Most importantly, inclusion agendas must not displace ambitions of the deeper anti-oppression social reforms needed to tackle health inequalities and create meaningful inclusion.
