A healthy and a fluorotic human molar tooth were studied by high‐resolution synchrotron microcomputer tomography (SRμCT) and compared with respect to their structure and mineral distribution. The teeth were measured in their full size, i.e. without introducing segmentation or cutting artefacts. Enamel and dentin were clearly separated on the basis of their different X‐ray absorption coefficient. No significant differences in the degree of mineralization were found between the healthy and the fluorotic tooth, except for a slightly rougher enamel surface of the fluorotic tooth.
