HEALTHY teeth is the theme in schools this week as part of a national campaign.
Youngsters across the Huddersfield area are taking part in events to promote better teeth for National Smile Week, which runs until Saturday.
Messages include brushing your teeth morning and night, cutting down on sugary foods and having regular checks at the dentists.
Arlene Bennett, oral health promotion officer for North Kirklees Primary Care Trust, said: "Half our 12-year-olds have or have had dental decay and a recent survey showed this situation is getting worse.
"We need to find different ways of educating and encouraging our young people so they look after their teeth better."
At Howden Clough Girls' School in Batley Year 7 pupils are to pose as hockey and rugby stars, using cardboard cutouts with space to insert their oral health messages.
It is hoped the scheme will encourage pupils to make more positive choices about dental health.
