A second public meeting on fluoridation issues will be held in Mosgiel next week.
It followed a successful meeting on the controversial topic last week, organisers said.
Dunedin Mayor Peter Chin and Dunedin city councillors have been invited to the meeting, to be held at the Coronation Hall in Gordon Rd on Tuesday at 7.30pm.
One of the organisers, Dennis Enright, said Mr Chin was unable to attend because of a previous engagement.
Mr Enright hoped some councillors would participate and outline their views on a possible extension of Dunedin city fluoridation to some areas, such as Mosgiel, which have previously not had a fluoridated water supply.
