Florida's new law banning fluoride in public water systems has drawn sharp criticism from dental professionals, who cite decades of evidence supporting its safety and effectiveness in preventing tooth decay.

Dr. Jeff Ottley, president of the Florida Dental Association, warned that the change will lead to a rise in cavities, particularly among children and underserved populations.

"Over the next two to three years, we will see an increase in the number of cavities, particularly in children and older adults who take multiple medications, which cause dry mouth," he said. "Those older adults will start getting cavities along the roof surfaces of their teeth and under existing restorations, like crowns and fillings."

Backers of the ban, including libertarian groups and some GOP legislators, have argued that "fluoride is a choice" and have recommended topical treatments, such as toothpaste, over what they claimed to be "mass medication."

Ottley stressed that fluoride occurs naturally in water, and the ban eliminates adjustments that allow cities to reach optimal levels for dental health.

He also predicted severe consequences, especially for Florida's Medicaid system and rural communities.

"The Medicaid system in Florida already has the lowest reimbursement rate across the country," he said, "and so you're going to have an influx in the number of kids looking, and parents looking to treat their kids who are on Medicaid, and the providers just aren't going to be there."

Ottley warned that higher Medicaid payments will be needed to attract dental-care providers, which he said could lead to ballooning costs.

His interim advice for parents: Seek prescription fluoride vitamins, and everyone should maintain rigorous brushing and flossing routines, cut their sugar intake and avoid post-brushing snacks before bed.
