Is There Fluoride in the Tap Water? A 2026 Map of 41 Towns Around Lincolnton
Two county water systems near Lincolnton stopped adding fluoride, in 2018 and July 2025. Alpine Pediatric Dentistry read every local water supplier's own report to map which towns still get fluoride, which do not, and where nobody says.
Key Takeaways
- Lincoln County Water has added no fluoride since 2018. Its 2025 report shows fluoride not detected, covering Denver, Iron Station, Vale, Lowesville, and Westport.
- Cleveland County Water stopped in July 2025, citing repair costs and operator safety; its feed system had been out of service over 70% of the time.
- Shelby, Hickory, Kings Mountain, Belmont, and Mount Holly water measured 0.57 to 0.86 ppm, around the 0.7 ppm national target.
- Gastonia's Two Rivers Utilities lists no fluoride result at all in its 2025 report, leaving 18 of 41 towns unconfirmed.
- The target is 0.7 milligrams per liter. The legal maximum is 4.0, and the 2024 federal IQ review looked at levels above 1.5.

What Just Happened
Two of the four counties around Lincolnton have stopped adding fluoride to county water. Lincoln County's fluoride equipment failed in 2018 and was never replaced; on January 6, 2025, county commissioners voted not to restart it, against the recommendation of the county Board of Health, and passed a formal resolution on February 17, 2025. Cleveland County Water followed in July 2025, when it "elected to permanently cease the addition of fluoride," according to its 2025 water quality report, citing repair and construction costs and the safety of operators handling fluorosilicic acid.
The local moves come during a national shift. Utah and Florida banned fluoridation statewide in 2025. In October 2025 the Food and Drug Administration (FDA) moved to limit fluoride drops and tablets for young children. The Environmental Protection Agency (EPA) began a new review of fluoride's health effects in 2026, and a North Carolina bill to ban fluoridation (House Bill 929) was filed in April 2025 and stalled in committee.
Why Parents Care
Fluoride helps tooth enamel resist and repair the acid damage that leads to cavities, and children get it from three main places: toothpaste, fluoride varnish at the dentist, and tap water. When the tap water source changes, the other two carry more of the load. Families who moved from Hickory to Denver, or who drink Cleveland County water near Shelby, often do not know their water changed at all, because the change appears only in a yearly report most people never open.
How Alpine Checked Every Town
Alpine Pediatric Dentistry downloaded the 2025 Annual Drinking Water Quality Report, also called a Consumer Confidence Report, from each public water supplier serving 41 places within a 38-minute drive of the Lincolnton office, and read the fluoride line in each report's table of inorganic substances. Where a town buys water from another system, the report names the seller. Each town was then placed in one of four groups.
| Group | What the report shows | Towns |
|---|---|---|
| Fluoride at the target level | 0.4 to 0.9 ppm, close to the 0.7 ppm target | 12 |
| No fluoride added | Supplier states it stopped, and fluoride is not detected | 10 |
| Not confirmed | Low level, a conflict between reports, no fluoride line, or no report online | 18 |
| Private wells | Natural fluoride only; level varies by well | 1 |
Only one report, the City of Shelby's, states in plain words that fluoride is added. The others list a measured level, and a level near 0.7 ppm in river or lake water reflects added fluoride, because natural levels in Piedmont surface water sit far lower.
Fluoride Measured in Each Supplier's Water
Parts per million (ppm) in the latest water quality report. The dashed line marks the 0.7 ppm level recommended since 2015.
What the Numbers Mean
Fluoride levels in water reports appear in parts per million, the same as milligrams per liter. These are the levels that matter.
The U.S. Public Health Service lowered its recommended level to 0.7 ppm in 2015. The EPA sets the legal limit at 4.0 ppm and a secondary standard of 2.0 ppm to prevent white marks on teeth. In August 2024 the National Toxicology Program reported, with moderate confidence, that fluoride above 1.5 ppm is linked to lower IQ in children, and stated that its review was not designed to judge water fluoridated at 0.7 ppm. No local report shown here exceeds 0.86 ppm.
The Research Behind the Debate
The Case for Fluoridation
- The Centers for Disease Control and Prevention (CDC) still recommends 0.7 ppm and cites about a 25% reduction in cavities.
- The American Dental Association (ADA) and the American Academy of Pediatric Dentistry (AAPD) continue to support community water fluoridation.
- The Cochrane review notes that the benefit is largest for families who have less access to dental care.
The Case for Caution
- Cochrane's October 2024 update found a smaller benefit in modern studies: about a quarter of a decayed baby tooth per child, at low certainty.
- The 2024 NTP review linked levels above 1.5 ppm to lower IQ and called for more research on lower levels.
- The EPA started a new toxicity review in 2026; a draft and public comment period come next.
The court fight over fluoride is also unsettled. A federal judge ruled in September 2024 that fluoride at typical levels posed an unreasonable risk under toxic substances law; on May 21, 2026, the Ninth Circuit vacated that ruling and returned the case to the lower court.

How to Check a Home's Water
- Find the supplier. The name is on the water bill. Homes outside town limits are often on county water, not city water.
- Open the yearly water quality report. Every public supplier publishes one by July 1 for the year before. Search the supplier's name plus "water quality report."
- Find the fluoride line. It sits in the table of inorganic contaminants. "ND" means not detected.
- On a private well, test the water. The county health department and the North Carolina Department of Health and Human Services well water program explain how to test for fluoride.
- Tell the dentist. The water source is part of a child's cavity risk assessment at the checkup.
What National Guidelines Say for Children
These are the current national recommendations on fluoride for children. A child's own dentist weighs them against the child's cavity risk and water source.
| Source of fluoride | Current national guidance |
|---|---|
| Toothpaste | ADA: a smear the size of a grain of rice under age 3; a pea-sized amount from 3 to 6; spit, do not rinse. |
| Fluoride varnish | U.S. Preventive Services Task Force (2021): varnish for all children from the first tooth through age 5. |
| Drops and tablets | FDA (October 2025): moved against unapproved ingestible fluoride for children under 3 and for older children at low or moderate cavity risk. ADA and AAPD: supplements remain an option for high-risk children on low-fluoride water, after a risk assessment. |
| Tap water | CDC: 0.7 ppm where communities fluoridate. Families on unfluoridated water or wells discuss other sources with the dentist. |

City of Lincolnton water measured 0.61 ppm in its 2024 report, close to the 0.7 ppm target, though the report does not say whether fluoride is added. Lincoln County Water, which serves Denver, Iron Station, and Vale, has added no fluoride since 2018.
Does Denver, NC Water Have Fluoride?
Denver is served by the Lincoln County Water System, which stopped adding fluoride in 2018. The county's 2025 water quality report lists fluoride as not detected, and commissioners voted in January 2025 not to restart it.
Did Cleveland County Stop Fluoridating Its Water?
Yes. Cleveland County Water permanently stopped adding fluoride in July 2025. City of Shelby and Kings Mountain water are separate systems and measured 0.57 and 0.61 ppm in their latest reports.
Does Gastonia Water Have Fluoride?
Two Rivers Utilities, which serves Gastonia, does not list a fluoride result in its 2025 water quality report. Until the utility confirms, the status is unknown. Towns that buy Two Rivers water, such as McAdenville and Ranlo, list none either.
How Much Fluoride Is Safe in Drinking Water?
The recommended level is 0.7 ppm. The EPA's legal maximum is 4.0 ppm, and its cosmetic standard is 2.0 ppm. The 2024 federal IQ review concerned levels above 1.5 ppm. Local reports range from not detected to 0.86 ppm.
How Is Well Water Tested for Fluoride?
The county health department arranges well water testing, and the North Carolina Department of Health and Human Services well water program lists what to test. Fluoride in well water is natural and varies from one well to the next.
