The Greens are urging the Gillard government to review its $490 million youth dental program after it was found that less than one-third of those eligible are accessing the service.
Under the teen dental program, 1.2 million teenagers are eligible for a $160 annual voucher, after their parents qualified for the Family Tax Benefit Part A.
However, according to the annual report released by the Department of Health and Ageing, just 30 per cent of grants were taken up in the last financial year.
The Greens requested an improvement to dental services when it assisted the Labor government to come into power in the last election.
Greens health spokesman Richard Di Natale told The Australian on Wednesday (December 28) that he considered the Labor program to be a "sign of a fragmented, patchwork system that provides a few bits and pieces and only helps at the margin".
According to the News Limited source, more than 400,000 people are currently waiting up to four years to access state-funded public dental schemes.
Those with private health insurance are able to avoid such waiting lists and receive rebates for a range of dental work, including diagnostic, preventative and restorative treatments.
Private health insurers pay more benefits for dental services than any other type of general treatment.
