Utah HB 81: the first statewide fluoridation ban, in force since May 7, 2025, with a pharmacist fluoride provision

What it says#

H.B. 81, Fluoride Amendments, is a three-page bill from Utah's 2025 General Session, sponsored in the House by Rep. Stephanie Gricius and in the Senate by Sen. Kirk A. Cullimore. Its long title says it "prohibits adding fluoride to public water systems," "allows a pharmacist to prescribe fluoride," and "directs the Division of Professional Licensing to establish guidelines for prescribing fluoride." No money is appropriated. Section 4 sets the effective date at May 7, 2025.

Section 1 repeals and reenacts Utah Code 19-4-111 under the heading "Prohibition of fluoride in public water systems." Subsection (1) defines fluoride as "a chemical compound that contains the fluoride ion and is used to fluoridate drinking water," and names fluorosilicic acid, sodium fluorosilicate and sodium fluoride. Subsection (2) is the operative sentence: "A person may not add fluoride to water in, or water that will be introduced into, a public water system." Subsection (3) closes the local route: "A political subdivision may not enact or enforce an ordinance that requires or permits the addition of fluoride to water in, or water that will be introduced into, a public water system." Section 3 repeals two sections from the earlier regime, 19-4-111.1 ("Provision of fluoridated water -- Request of resident") and 19-4-111.2 ("Provision of fluoridated water -- Emergency circumstances").

Section 2 is the part most coverage skipped. It amends 58-17b-627, the section that since January 1, 2022 has let a Utah pharmacist prescribe a prescription drug or device when doing so is within the pharmacist's training and experience, the drug is designated by the Division of Professional Licensing by rule, and it is not a Schedule I through IV controlled substance. The division's rules must begin with drugs that address a public health concern designated by the Department of Health and Human Services; the bill adds "(vi) fluoride" to that list after post-exposure HIV prophylaxis, pre-exposure HIV prophylaxis, self-administered hormonal contraceptives, smoking cessation and naloxone. The division must also write guidelines for notifying the patient's primary care or other provider, for preventing over-prescription, and for when to refer. Nothing in the section requires a pharmacist to write a prescription.

DOPL's Utah Guidance for Fluoride, approved November 18, 2025, fills that in. A pharmacist "may prescribe systemic fluoride supplements to a person aged 3 to 16 years at high risk for tooth decay," must provide training and education before dispensing, and may hand out written materials but not in place of a direct consultation. Every recommendation "require[s] knowledge of the natural fluoride level of the patient's home water," which the guidance says is available from the Department of Environmental Quality for public systems and, for private wells, from a certified laboratory. The dosing table, adapted from the 2010 ADA Council on Scientific Affairs schedule and marked as modified to reflect FDA guidance as of October 31, 2025, gives 0.5 mg a day for ages 3 to 6 and 1 mg a day for ages 6 to 16 where water fluoride is below 0.3 ppm, half those doses at 0.3 to 0.6 ppm, nothing above 0.6 ppm, and nothing from birth to 3 years. Dispensing must be in tamper-resistant packaging and limited to 100 tablets or a 100-day supply, whichever is less.

The fiscal note estimated that each of "the 24 Utah public water systems stopping adding fluoride to their water" would save about $20,000 to $150,000 a year beginning in May 2025, with small state costs for staff time and data systems. The Utah Department of Health and Human Services said on May 2, 2025 that the law "impacts about 1.6 million Utahns who live in Davis and Salt Lake counties, as well as residents of Brigham City," that "most people in Utah live in an area where there isn't enough natural fluoride in the water to protect their teeth," and that supplements are recommended for children 6 months to 16 years in such areas, with some adults also candidates. Note the gap: DHHS describes supplements from 6 months, while the pharmacist pathway DOPL wrote begins at age 3, so the youngest children still need a dentist or physician to prescribe.

Who it applies to#

Every public water system in Utah, and every person and every city or county that might add fluoride or require it. Naturally occurring fluoride is outside the section's definition, which reaches compounds used to fluoridate; private wells and bottled water are not public water systems. Pharmacists gained authority, not a duty. For a dental office, the people affected are the roughly 1.6 million residents of the two counties and one city that had been fluoridating, and every child among them whose caries risk assessment assumed fluoridated tap water.

The ADA's position is on the record in two places on ada.org. Before the signature the ADA sent a letter, signed by President Brett Kessler and Interim Executive Director Elizabeth Shapiro, urging a veto: "With the weight of the evidence and nearly universal support of community water fluoridation in all corners of the health care sector, we urge your veto of [House Bill] 81." After it, on March 28, 2025, the ADA said it was "disappointed in Governor Cox and the Utah Legislature's wanton disregard for the oral health and well-being of their constituents," cited the CDC's estimate that optimally fluoridated water saves $6.5 billion a year in treatment costs and that fluoridated communities have 25 percent fewer cavities, and quoted Dr. Kessler: "We urge legislators and voters across the country not to make Utah's significant mistake."

What changed#

Before May 7, 2025 Utah law left fluoridation to local decision, with sections allowing residents to request fluoridated water and allowing it in emergencies. HB 81 removed the choice statewide and repealed both sections. It was the first statewide ban in the country; Florida followed in July 2025 with a differently worded law that never names fluoride, covered in its own entry here. The science argument behind both bills runs through the 2024 NTP monograph, also in this directory, which the ADA reads as not addressing water at 0.7 mg/L. What is new for the profession is the pharmacist prescribing route: a Utah parent can now get a supplement prescription at a pharmacy for a child aged 3 to 16, and the DOPL table already reflects FDA guidance on ingestible fluoride issued in late 2025, which has its own entry.

The Utah Legislature's bill page for H.B. 81 carries the bill text, the enrolled PDF, the status history and the roll-call votes; the page loads its content by script, so the enrolled PDF and the fiscal note PDF are the reliable direct links. The DOPL guidance is a PDF on the Utah Department of Commerce site, and the May 2, 2025 DHHS notice is on dhhs.utah.gov. The ADA's reaction is in its March 28, 2025 press release and the ADA News article of the same day, both on ada.org and free to read.
