Arizona Senate Advances Bill Banning Fluoride Additives In Public Water Systems

By Staff Reporter |

A committee within the Arizona Senate approved a bill banning fluoride additives in public water systems. 

The Senate Committee on Government advanced SB 1019 solely through Republican support. Democratic lawmakers voted against the bill based on the opposition of certain major health organizations.

The bill would prohibit individuals and political subdivisions from adding fluoride or fluoride-containing compounds to public drinking water.

State Sen. Janae Shamp (R-LD29), a registered nurse, sponsored the bill.

Shamp argued that water fluoridation is no longer necessary for public health due to the widespread availability of fluoride in dental products and treatments. Shamp also cited research connecting adverse health effects to ingesting fluoride: neurodevelopmental harms resulting in IQ reduction, weakened bones, arthritis, and thyroid dysfunctions.

“It’s more effective when applied to the teeth rather than ingested,” said Shamp during a committee hearing on Wednesday. “If there is absolutely any possibility that their child could have their neurodevelopmental [development] delay[ed] because they’re ingesting systematically a product that works better topically, I would question anyone who is against stopping [this ban].”

Shamp dismissed opposition to the bill from certain healthcare organizations as the typical resistance to change among institutions. Among those opposed are the Arizona Dental Hygienists Association, Arizona Dental Association, and Arizona Public Health Association. 

“As we move forward with the science, we have to make sure we’re staying up to date with evidence-based practice,” said Shamp. “The evidence is showing this is not the way to decrease tooth decay in the population.”

State Sen. David Farnsworth offered his own anecdote on the matter. Farnsworth said he was diagnosed with fluoride sensitivity after suffering headaches while using the first formula for Crest toothpaste to brush his teeth.

Jessica Robertson on behalf of the Arizona Dental Association and American Academy of Pediatric Dentistry said water fluoridation was necessary because certain communities, especially tribal communities, were too poor to afford toothbrushes or toothpaste. Robertson credited water fluoridation for her not coming down with cavities in her youth. 

Valerie Brady on behalf of the Arizona Dental Hygienists Association argued against the bill as a “significant risk to public health.” She said that thousands of studies and decades of scientific evidence back the perception that fluoridated water prevents tooth decay. Brady said fluoridated water was significantly impactful to communities with poorer dental hygiene habits or inconsistent dental care.  

“It is the ability to provide consistent low-level exposure to fluoride ions in the mouth, helping prevent tooth demineralization and promoting enamel remineralization,” said Brady. 

Shamp questioned why those opposed to the bill don’t factor in the variable levels of fluoride people might ingest — or the disparate impacts those variable amounts could cause. The senator claimed this was the opposite of informed consent.

“The fact of the matter is this is a chemical that is added to water and there is absolutely no one out there telling people, ‘Well, you should use this much toothpaste if you drink this much tap water,’” said Shamp. “You don’t know how much someone is ingesting. You don’t know if their only source of water is tap water. You don’t know if they’re using mouthwash three times a day.”

Arizona Senator Proposes Ban On Fluoride Additives In Public Drinking Water

By Jonathan Eberle |

Arizona State Senator Janae Shamp (R-LD29) has introduced legislation that would prohibit the addition of fluoride and fluoride-containing compounds to public drinking water systems across the state. The proposal, Senate Bill 1019, would bar state agencies, municipalities, and other political subdivisions from fluoridating public water supplies. Shamp, a registered nurse and former Senate majority leader, says the bill is intended to limit what she characterizes as government-mandated medical treatment and to give individuals greater control over their health decisions.

In announcing the legislation, Shamp cited concerns about the practice of water fluoridation, including questions about consent and potential health risks. Supporters of the bill argue that fluoride is widely available through toothpaste, mouth rinses, and dental treatments, making its addition to drinking water unnecessary.

Shamp also referenced research suggesting that excessive fluoride exposure may be associated with adverse health outcomes, including potential impacts on cognitive development in children and risks to bone health. Public health authorities, including the Centers for Disease Control and Prevention, have long maintained that water fluoridation at recommended levels is safe and effective in reducing tooth decay, a position that has been the subject of ongoing debate nationwide.

“Medical decisions should be made by individuals and families, not imposed through public utilities,” Shamp said in a statement. She added that banning fluoridation would allow residents to choose whether and how they use fluoride products.

The senator also pointed to financial considerations, arguing that eliminating fluoridation could reduce costs associated with chemicals, equipment, and maintenance for water systems. Those savings, she said, could be redirected toward infrastructure improvements or water conservation efforts. The bill comes as other states have reconsidered fluoridation policies in recent years, with lawmakers in Utah and Florida passing measures to limit or ban the practice in certain jurisdictions. Shamp framed SB 1019 as part of a broader movement emphasizing individual choice and medical autonomy.

If approved by the Legislature and signed into law, Arizona would join a small but growing number of states restricting fluoride use in public water systems. The bill is expected to generate debate among lawmakers, public health officials, and dental professionals as it moves through the legislative process.
