The aim of the present study was to identify the characteristics and severity of tooth wear in children aged 2 to 5 years attending a kindergarten in the city of Medellin. The study population comprised 92 children aged 2 to 5 years attending a kindergarten in Medellin; the final sample included 86 children selected using a non-probabilistic sampling method. All assessments were performed using the index devised by Hansson and Nilner (1989). Prevalence of tooth wear in the studied population was 100%. The observed results confirm previous findings showing that the severity of tooth wear is proportionally related with increase in age, and is mainly due to the physiological wear of teeth. No significant differences in tooth wear facets were observed among the different types of teeth (incisors, canines, molars). It is necessary to develop validated, precise, and comparable indices that allow establishing the etiology and orienting treatment of non-physiological tooth wear.
