THREE-year-olds in York have better dental health than most of the country.

Just 6.9 percent of nursery school children in York have visible signs of tooth decay, as opposed to 13 percent in Yorkshire and the Humber and 12 percent nationally.

City of York council took over responsibility for promoting oral health when public health functions were transferred to the authority last year.

The survey was commissioned by Public Health England, and also found the prevalence of Early Childhood Caries - a particular type of tooth decay - was lower in York than across the UK.

Tooth decay is caused by consuming too many sugary foods and drinks too often. Unless this lifestyle issue is addressed, there is a much higher risk of further tooth decay in permanent adult teeth and throughout later life. It can be prevented by eating a healthy balanced diet which limits the amount of food and drink that are high in sugar, and also by brushing teeth at least twice a day, once before bed, using fluoride toothpaste.
