Summary. Objectives. To establish the prevalence of tooth erosion in a sample of 12‐year‐old children and to monitor changes over the subsequent 2 years. Methods. A random sample of 1753 children aged 12 years was drawn from all 62 state maintained schools in Leicestershire. A total of 1308 were re‐examined 2 years later. Erosion was recorded on incisors and first molars using an erosion index based upon that from the Children's Dental Health in the United Kingdom 1993 survey. A score was also allocated to each subject according to the most advanced lesion in the mouth. Results. Erosion was present in 56·3% of subjects at age 12 and 64·1% at age 14. Deep enamel or dentine was eroded in 4·9% and 13·1% of subjects, respectively, at the same ages. One hundred and sixty‐one (12·3%) children who were erosion‐free at 12 years of age developed erosion over the subsequent 2 years. Boys had more erosion than girls, as did white compared to Asian children. Associations were found between erosion experience and social deprivation. Conclusion. New erosive lesions developed in 12·3% of the subjects between the ages of 12 and 14 years. New or more advanced lesions were seen in 27% of the children over the 2 years of the study. Males, white children and social deprivation were significantly associated with erosion experience.
