Warning over children's dental health

Nearly 500 young children a week are being admitted to hospital to have rotten teeth removed, and according to NHS figures tooth decay is now the main reason that 5 to 9 year olds in England are treated in hospital.

Dentists say in some cases, children need to have all of their baby teeth extracted.
