Gosford City Council voted to fluoridate in 2007. A four-year study compared it with Wyong, which had been fluoridated for over 40 years.
Health authorities, including the NHMRC, recommend drinking fluoridated tap water to reduce tooth decay. Some residents prefer to reduce their intake, and that's a personal choice.

Coverage: about 93% of residents (2017). First fluoridated: Yass, 1956.
