Atlas of tooth development and eruption

We have developed a comprehensive evidence based atlas to estimate age using both tooth development and alveolar eruption for individuals between 28 weeks in utero to 23 years; it shows a sequence of diagrams representing a continuum of developmental ages without gaps or overlaps 1.c

Data was collected from developing teeth from 72 pre-natal and 104 post-natal skeletal remains of known age-at-death were examined from collections held at the Royal College of Surgeons of England, and the Natural History Museum, London UK (M 91, F 72, unknown sex 13) 2,3. Data was also collected from archived dental radiographs of living individuals (M 264, F 264) 4.

Median stage for tooth development and eruption for all age categories was used to construct the atlas. Tooth development was determined according to Moorrees, Fanning and Hunt 5,6 and eruption was assessed relative to the alveolar bone level 7,8. Intra-examiner reproducibility was 0.85 calculated using Kappa on 755 teeth (65 individuals). 

Diagrams were drawn to represent monthly dental development in the last trimester, 2 weeks around a full gestation (40 weeks birth), quarterly development for the first year of life, and yearly development thereafter.

This is an updated version that is accessible (November 2025). Translated versions have not been updated.

The 3rd edition of electronic interactive software is now available.

Playback mode shows standard deviation for males and females combined for each age category (from AlQahtani et al. 9).
