The lead, cadmium and zinc content of deciduous and permanent teeth extracted from Romano‐British skulls was measured using atomic absorption spectrometry. Mineral content is reported in μg/g of samples obtained by pulverising whole teeth prior to chemical preparation and analysis. The overall levels of lead and zinc were higher in deciduous than permanent teeth.Lead levels in conservatively cleaned teeth were twice as high in deciduous compared to permanent teeth but were reduced following abrasive removal of surface enamel especially in deciduous teeth. It was concluded that the higher lead content in deciduous teeth is mainly in the outer layer of enam
