Health Minister Howard Quayle says his department has no plans to fluoridate the Island's water supply.
During this morning's Tynwald questions, he was pressed on the issue by Onchan MHK Zac Hall who described it was a way of harmlessly cutting dental health problems.
But Mr Quayle said his department consulted the public in 2008 - and received a resounding "no".
He added there are no plans to introduce fluoride into drinking water in the near future:
