Tooth decay in 11-12-year-olds in Wales has significantly declined, according to a new report.
The Welsh Oral Health Information Unit report shows that the percentage of children experiencing obvious tooth decay has dropped by 15% - from 45% in 2004/2005 to 30% in 2016/2017.
The Welsh Government launched the Designed to Smile campaign in 2008/09 to improve children's oral health and has been piloting a preventative approach to care in dental practices across Wales.
Research shows that dental decay often starts early.
The Chief Dental Officer for Wales says investment in prevention services is key as it is largely preventable.
The Health Secretary, Vaughan Gething AM, says although he is pleased with the progress, there is no room for complacency.
The report was published by Cardiff University in partnership with Public Health Wales.
