Moreton Bay Regional Council (MBRC) will initiate talks with Unitywater and the Sunshine Coast Regional Council over removing fluoride from drinking water supplies.
Mayor Allan Sutherland said while MBRC had yet to make a decision on whether to stop fluoridation, it should find out what would need to be done.
Councillors have recently heard from Queensland Health officials on the benefits of fluoride and also from anti-fluoridation campaigner Dr Paul Connett.
Councillor James Houghton (Div 5), who raised concerns about fluoridation in council meeting in December, said he was more convinced than ever that it was a poison.
He said Dr Connett told councillors on February 13 fluoride had never been shown to be safe or effective.
Cr Houghton could not explain why health authorities such as Queensland Health said fluoride was safe for humans (in the right dose) and beneficial to teeth.
He said thalidomide, DDT and asbestos were also once regarded as safe.
Overseas health authorities that support fluoridation include Britain’s National Health Service, The United States’ Centers For Disease Control and Prevention and the US Surgeon General.
Queensland councils that have decided to stop fluoridation include Fraser Coast, Cairns, Bundaberg, Tablelands, Burdekin and Doomadgee.
The Gold Coast, Redlands and Sunshine Coast have yet to decide.
