People in Ramsey who have received copies of the DHSS leaflet called 'Water Flouridation - Information for Isle of Man residents' are being advised to throw them away.
The DHSS, which is distributing the material as part of an ongoing campaign, has been forced to amend the content, after an inaccuracy was pointed out during a debate in Tynwald.
It says 40 'pre-amended' versions of the leaflet were handed out at the Water Flouridation meeting in Ramsey on Monday.
Anybody who has the incorrect version will receive a final, amended copy when 40,000 are sent out to every home in the Island next week.
The leaflet is part of a public consultation exercise on the proposal to flouridate the Island's water supply, to tackle the growing problem of tooth decay.
