The State Government has begun fluoride ads on radio and TV to prepare south-east Queenslanders for the change later this year.
Fluoride will be added to drinking supplies around the state over the next few years, beginning in the south-east.
Health Minister Stephen Robertson says the Government is open and accountable about fluoride.
“[We’re] not being sneaky, but being very up front about it,” he said.
Premier Anna Bligh says similar advertisements may also be aired for recycled and desalinated water next year.
She says she welcomes a debate about recycled water, as long as it is honest.
“I do call for that debate to be well informed, and for it to be honest and for it to be accurate,” she said.
She says some newspaper reporting of the recycling issue has been irresponsible.
