The opposition has pledged $4.5 million to expand dental health services at Winnunga Nimmityjah Aboriginal Health Services if they win government at the October election.
Winnunga CEO Julie Tongs has welcomed the funding announcement and called on Labor and the Greens followed their lead.
The $4.5 million would go towards the fit out of two new dental suits at the new health centre currently under construction at Winnunga.
Opposition leader Alistair Coe said the funding would make a huge impact for the region.
"Dental services are very much in demand right across the ACT," he said.
"There is no doubt the capacity [at Winnunga] is stretched and there is a need for additional investment.
"We know that many emergency department presentations are linked in one way or another to dental health.
"It's just not right that aboriginal people continue to suffer by way of inadequate health services."
Ms Tongs said the centre was desperate for more dental facilities.
"We need to make sure that nobody gets left behind when we're talking abut healthcare, and often our people do," she said.
"We are very very grateful that we do have support to do that."
She said without the $4.5 million, the ground floor of the new centre would remain a cold shell.
"I'm now hoping the government will follow the lead and that we can get tripartisan support for this initiative," Ms Tongs said.
"We've had the same conversations with the government as that I've had with the Commonwealth and the ACT Liberal Party.
"Everyone has had an opportunity.
"This is an election year and we're hoping that people actually see the worth of Winnunga and what we do."
Health Minister Rachel Stephen-Smith said she had been in discussions with Ms Tongs in recent months about an additional $4.5 million required to completely fit out the new building.
"Our view has been that the Commonwealth should contribute this additional funding, as the main funder of Winnunga's services and in line with its responsibility for primary care," she said.
"I formally wrote to Minister Hunt on February 10, seeking the Commonwealth's commitment to this funding and we have had a number of productive conversations since then. I am optimistic that we will have more to say about this in the near future."
