Public Health England has published the results of this first national survey, which took place in the academic year 2013 to 2014.
The results of the survey, broken down by region, shows:
wide variation in tooth decay prevalence and severity in both 5 and 12 year old children attending special support schools in England
children in special support schools have slightly lower levels of tooth decay than children in mainstream schools but are more likely to have their teeth extracted
children who experience decay also have more teeth affected and poorer oral hygiene.
