Another Queensland council has opted out of water fluoridation, despite a state health department recommendation the program should continue.
The Liberal National Party (LNP) last year scrapped the previous Labor government's policy to make water fluoridation compulsory.
Even though it is now voluntary, Queensland Health Minister Lawrence Springborg says councils are still encouraged to put fluoride in drinking water.
"If they want to make a different decision then that's fine by us," he said.
The Fraser Coast Regional Council is the latest local government to opt out, joining other major centres like Cairns and Bundaberg, and smaller councils like Burdekin and South Burnett.
Mr Springborg says there are other strategies for improving dental health.
"Good oral health hygiene is the best and most effective way," he said.
Many other local governments are still considering their decisions.
Mr Springborg says fluoride is still recommended, despite the policy change.
"The official position of Queensland Health is that we do encourage councils across Queensland but we do understand and respect that there are differing opinions and because of the nature of the issue, they might want to make a different decision," he said.
"The Fraser Coast council has made that decision and we respect that."
LNP backbencher Jason Woodforth says he is trying to gather support in the party-room to remove fluoride from all water supplies in Queensland.
