"The evidence shows that one-third of Australia's five to six year-olds have had decay in their baby teeth."
This is an unacceptably high rate and puts these children at risk of poor oral health in their development and adult years," says Dr Hugo Sachs, Federal President of the Australian Dental Association.
Australia's Oral Health Tracker was developed by dental academics/ researchers, clinicians, policy and public health experts and was released by the ADA to coincide with World Oral Health Day.
It sets targets for improving the oral health of children, young people and adults by the year 2025 - aligned with the World Health Organisation's targets for global prevention and reduction in chronic diseases.
Public health expert Professor Rosemary Calder, Director of the Australian Health Policy Collaboration (AHPC) at Victoria University says preventable tooth decay is not only painful but very costly.
The figures show in 2015-16, there were 67,266 potentially preventable hospitalisations for oral health problems and almost one-third of these were children under the age of nine years.
"Preventable hospital admissions are of concern to all governments. One in ten preventable admissions are due to dental conditions, mostly untreated tooth decay," said Professor Calder.
Earlier this month, the Royal Children's Hospital National Poll found by early primary school, one in four children needed a tooth filling and one in ten required a tooth pulled out because of decay. About one in 20 required a hospital visit to treat a decayed tooth.
With poor oral health linked to a range of diseases in adulthood it's critical governments work to ensure healthy oral health habits among the young, said Dr Sachs.
