This retrospective analysis reviewed the demographics of patients sustaining dental avulsion injuries at a tertiary dental hospital in Sydney, Australia. Data were extracted from dental records of patients who presented with avulsed permanent anterior teeth and were treated between 1 January 2001 and 30 June 2021. Demographic, clinical and radiographic data from 91 patients with 117 avulsed permanent anterior teeth were available for analysis. The median age of the patients was 12 years (IQR 9.0–17.0). Males accounted for 68.4% of avulsion injuries. Non‐organised sports were the most common cause of injury (42.7%). Maxillary central incisors were the most frequently avulsed tooth (83.3%). Peak prevalence of injuries occurred on the weekend. The findings from this study may reflect regional factors such as climate and participation in sport. Anticipatory guidance should be provided to patients at elevated risk of dental avulsion.
