We review how the Wellcome Collection exhibition ‘Teeth’ enacts meanings from an educational anthropology and Science and Technology Studies perspective. The exhibition tells the history of dental science. It starts with accounts of the painful procedures and social inequalities of early oral healthcare. As it moves towards the present day it shows improved scientific knowledge, tools and public health promotion, and closes with current sophisticated technologies and practices. However it underrepresents contemporary social inequalities. We conclude that science communication exhibition curators should strive to represent the problems of today as well as those of the past.
