National Dental Epidemiology Programme for England: oral health survey of 5-year-olds 2019

Overall, 23.4% of 5-year-old children in England whose parents gave consent for
participation in this survey had experience of dental decay. This was similar to the
finding of the previous survey of 5-year old children in 2017, where 23.3% of the
surveyed children had experience of dental decay. Among the 23.4% of children with
experience of dental decay, the average number of teeth with experience of dental
decay was 3.4 (at age 5-years, children normally have 20 primary
teeth).
