The advisory board voted 6–1 to distribute a memorandum drafted by county medical director Dr. Remington Nevin, accompanied by the U.S. Food and Drug Administration’s Oct. 31, 2025, notice about restrictions on unapproved ingestible fluoride prescription products.

Nevin summarized federal findings that some ingestible fluoride products (for example, certain sodium-fluoride tablets) should not be used in children under age 3 and that prescribers should limit use in older children who are not at high risk of tooth decay. He told the board he had not seen any state-level notice emphasizing the FDA action and proposed the county alert local clinicians and dental providers. "It would be appropriate for us to distribute this memo ourselves," Nevin said, citing the county advisory board’s recent recommendation against adding ingestible fluoride to municipal water systems.

Board members asked staff whether dentists and prescribers had received the federal guidance and whether the state had notified local clinicians; staff said they had not received statewide notice as of the meeting. A motion to distribute the memorandum with the FDA news release as an enclosure was moved, amended to include the FDA release, and approved by the board.

The medical director said he will forward the memo and encourage other local health departments and clinicians to share the information; he also noted his intent to discuss the issue with state and federal officials to reconcile differing federal and Michigan practices on vaccine information statements and other guidance.
