It seems that no fully blooded African has teeth that look 'caucasian' (i.e. no noticeable prognathism/overbite).
Europeans, Arabs etc.. seem to have it in very low rates among adults but a large number of blacks from sub-Saharan Africans to AA's have it significantly.
I need the image for the orthodontist. It can be a black man or woman but with teeth 'like white people'.
Like this?
