Mean times of emergence of the permanent teeth, except the third molars, and mean times of onset of specific dental stages were studied cross‐sectionally in nearly 8,000 Danish children. In both sexes, a tendency for grouped emergence was observed, the teeth within a group showing similar mean times of emergence. The following groups were distinguishable: (1) the first molar in each jaw and the mandibular central incisor, (2) the maxillary central and mandibular lateral incisor, (3) the mandibular canine and the first premolar in each jaw, and (4) the maxillary canine and the second premolar in each jaw. The sex difference in emergence timing ranged from 2–11 months. In Denmark, the first visit to the Child Dental Services usually takes place when the children enter school in the year they attain the age of 7 years. The present findings indicate that, in order to include the initial phase of permanent tooth emergence, organized dental care should be introduced at least 1 year earlier.
