Fluoride in Lebanon, TN

It depends on which system serves you — Lebanon is split. The Lebanon Water System, the city's own Cumberland River system, does not fluoridate: it stopped in September 2007 and has not restarted. But Gladeville Utility District and West Wilson Utility District, which also serve Lebanon addresses, both add fluoride and reported 0.68 mg/L averages in 2025. Check whose name is on your water bill.

According to the Wilson Post's reporting on the decision, Lebanon stopped its fluoridation process in September 2007 citing difficulty finding quality powdered sodium silicafluoride after Hurricane Katrina — inferior product caused serious malfunctions with the feed system's equipment, per a report by the city's Commissioner of Public Works and its Waterworks Superintendent. The Wilson County Health Council later took up the lack of fluoride in county water systems as a dental-health concern for Wilson County children.

On Gladeville Utility District water: 0.68 mg/L on average (range 0.54–0.90 mg/L, 2025 report). On West Wilson Utility District water: also 0.68 mg/L on average (range 0.36–0.96 mg/L, 2025 report). On the city's own Lebanon Water System — and on Wilson County Water & Wastewater Authority areas supplied by the city — there is no level to publish, because the city does not add fluoride. Wilson County authority areas supplied by Gladeville get Gladeville's 0.68; areas supplied by Consolidated Utility District get its water at 0.34 mg/L on average (range 0.03–0.80 mg/L, 2024 report).

It is just below the CDC recommended level of 0.7 mg/L — close, but below it, and this page states that plainly rather than rounding it up. It is far below both EPA standards: the secondary (non-enforceable) standard is 2.0 mg/L and the enforceable maximum contaminant level (MCL) is 4.0 mg/L. Brushing twice daily with fluoride toothpaste covers the rest of what your teeth need.

Yes — on every Lebanon system. On Gladeville and West Wilson water at 0.68 mg/L, fluoridated water is background exposure and toothpaste delivers the concentrated dose; brush twice a day with fluoride toothpaste. On the city's non-fluoridated water, toothpaste matters even more: it is the main daily cavity protection, with no background layer underneath it.

The ADA's guidance: for children under age 3, use a smear of fluoride toothpaste about the size of a grain of rice. For ages 3 and up, a pea-size amount is enough. Supervise brushing, teach your child to spit the toothpaste out rather than swallow it, and remember that more paste on the brush does not mean cleaner teeth — the small amounts are deliberate, because young kids swallow some no matter what.

For many people, yes — and the answer sharpens by system. On city water with no added fluoride, varnish is one of the main ways to put a stronger dose directly on the teeth. On Gladeville or West Wilson water just below the CDC target, it remains worthwhile for kids and for adults at higher cavity risk — people with recent cavities, dry mouth, braces, or exposed roots. If your cavity risk is low, ask your dentist to explain your risk either way rather than accepting or skipping it on autopilot.

No utility fluoridates private well water — nobody adjusts it at all. Well water can contain some naturally occurring fluoride, a lot, or almost none, and you cannot tell by taste. If your home is on a well in Wilson County, have the water tested before assuming anything about its fluoride level, and tell your dentist you are on well water so your fluoride plan reflects it.

Start with your own utility's current water quality report — Gladeville's and West Wilson's 2025 reports are linked in the sources below and each lists fluoride with its average and range; the Wilson County authority publishes its report per supply. You can also check CDC's My Water's Fluoride, which tracks fluoridation status and levels by water system. If your bill names the city system, its status — not fluoridated since 2007 — is a matter of public record in Wilson County reporting.
