Louisiana Senate advances water fluoridation removal bill
Dentists in Louisiana should monitor House action on fluoridation policy affecting public health messaging and preventive strategies.
The Louisiana Senate voted 26-7 on April 8 to advance Senate Bill 4, which would allow communities with fluoridated water supplies to vote on removing fluoride. Currently, public water systems in Louisiana with more than 5,000 service connections are required to add fluoride.
How the bill would work
Senate Bill 4 gives residents in fluoridated communities the power to initiate a removal vote. A petition signed by 15 percent of the community's residents would trigger a public referendum on whether fluoride should remain in the water supply. The bill now moves to the House of Representatives for consideration.
What changed from the original proposal
The Senate approved a modified version of the bill. The original proposal would have eliminated the state's fluoridation requirements entirely for systems serving more than 5,000 people and let communities vote to add fluoride instead. The revised bill narrows the scope by allowing only those communities already receiving fluoridated water to vote on its removal, rather than reversing the entire state mandate.
