Fluoride in Fairview, TN
Fairview’s 37062 ZIP spans three counties and four water systems. Two supply chains are verified — both fluoridated, both below the CDC target — and one system’s figure couldn’t be verified. Here is the split, utility by utility.
Fairview’s water is fluoridated — at two verified levels, both below target. Most of Fairview city drinks Harpeth Valley water through H.B. & T.S., averaging 0.53 mg/L. Dickson-side addresses on the Water Authority of Dickson County average 0.61 mg/L. Both sit below the CDC recommended 0.7 mg/L, and far below EPA limits.
How this page works: the levels below come from each treating utility’s own published water quality reports, presented by supply chain — because in Fairview, asking “what’s the fluoride level?” without asking “whose water?” first is how wrong numbers happen. One Fairview-area system’s figure could not be verified, and this page says so rather than filling the gap. New to the topic? Start with our full fluoride guide.

Fairview’s fluoride, by supply chain
Everything on this page traces back to these facts, from the treating utilities’ own published water quality reports.
LEVEL HVUD-supplied water (most of Fairview)
0.53 mg/L average
Range 0.25–0.65 mg/L, Harpeth Valley Utility District 2025/26 report. Below the CDC recommended 0.7 mg/L — stated plainly. This is the water H.B. & T.S. Utility District distributes to most of Fairview city, and the water direct HVUD customers receive.
LEVEL WADC water (Dickson-side addresses)
0.61 mg/L average
Range 0.29–0.88 mg/L, Water Authority of Dickson County 2025 report. Also below the CDC recommended level — close to it, but below.
STATUS Fluoridated — adjusted on both verified chains
Both treating systems add fluoride: HVUD at its Cumberland River plant, and WADC (whose report lists fluoride’s source as an additive to promote strong teeth).
UTILITY Four utilities serve Fairview 37062
H.B. & T.S. UD (TN0000699, ~37,803 served; buys HVUD water) · Water Authority of Dickson County (TN0000191, ~66,725) · Second South Cheatham UD (TN0000645, ~9,049) · Harpeth Valley UD (TN0000286, ~64,359; the wholesale treater, plus some direct customers).
2ND S. CHEATHAM Figure not verified
Second South Cheatham Utility District serves the Kingston Springs / Pegram side of the Fairview area. We could not retrieve a fluoride figure from its own reporting that we can stand behind, so this page publishes no level for that system.
How Fairview’s levels compare
Fairview has two verified levels, not one — so the table carries both, next to the three benchmarks that matter, each labeled for exactly what it is.
| Benchmark | Level | How Fairview compares |
|---|---|---|
| HVUD-supplied water (via H.B. & T.S.), 2025/26 | 0.53 mg/L avg | Range 0.25–0.65 mg/L. Covers most of Fairview city. Below the CDC recommended level — we won’t round it up to the target. |
| Water Authority of Dickson County, 2025 | 0.61 mg/L avg | Range 0.29–0.88 mg/L. Covers Dickson-side Fairview-area addresses. Also below the CDC recommended level. |
| CDC recommended level | 0.7 mg/L | Both verified Fairview supply chains run below this — HVUD water at roughly three-quarters of it, WADC water at roughly seven-eighths. |
| EPA secondary (non-enforceable) standard | 2.0 mg/L | Both levels are far below this guideline, which is aimed at preventing cosmetic effects like tooth discoloration. |
| EPA enforceable maximum contaminant level (MCL) | 4.0 mg/L | Both levels are far below the legal limit. |
Second South Cheatham Utility District has no row in this table because we could not verify a fluoride figure for it — an empty slot is the honest answer for that system. Its customers should read its own current water quality report.
Fairview is not one water system
Which level is yours depends on your supply chain: Harpeth Valley’s Cumberland River plant (0.53 mg/L average), delivered by H.B. & T.S. or by HVUD directly — or the Water Authority of Dickson County (0.61 mg/L average) on the Dickson County side. A third system, Second South Cheatham UD, serves part of the area with a figure we could not verify. Check your water bill for your utility’s name before assuming either number is your number.
Do you still need fluoride toothpaste?
Yes — and this is the point people most often get backwards.
Yes — on both of Fairview’s verified supply chains, and this is the point people most often get backwards. Fluoridated drinking water is background exposure. Every glass of water bathes your teeth in a low level of fluoride, and that steady, low-level contact genuinely helps enamel resist acid. But it is a base layer, not the main event. Fluoride toothpaste delivers a much more concentrated dose directly onto the enamel, twice a day, right where decay starts.
That holds at HVUD’s below-target 0.53 mg/L and at WADC’s 0.61 mg/L alike: brush twice daily with fluoride toothpaste. If you have been skipping fluoride toothpaste because “it’s in the water anyway,” the water was never carrying that load on its own.
Fluoride and kids: the amounts matter
Young children swallow toothpaste, so the ADA’s guidance is about using the right small amount — not about avoiding fluoride toothpaste.
UNDER 3 A rice-grain smear
For children under age 3, use a smear of fluoride toothpaste about the size of a grain of rice. That tiny amount is deliberate — it protects the teeth while keeping what gets swallowed to a minimum.
AGES 3+ A pea-size amount
From age 3 up, a pea-size amount is enough. A ribbon of paste running the length of the brush is several times more than a child needs.
- Supervise brushing. An adult should be watching (and helping) until a child can reliably spit and rinse on their own.
- Teach spitting, not swallowing. Spit the toothpaste out when done; swallowing it as a habit is what the small amounts are designed to guard against.
- Don’t load the brush. More paste does not mean cleaner teeth — it mostly means more swallowed.
What about fluoride varnish at the dentist?
An in-office fluoride treatment or varnish is a much stronger, targeted dose than anything in tap water or toothpaste.
If your Fairview water comes from HVUD at 0.53 mg/L — below the CDC recommended level — varnish remains worthwhile for kids and for adults at higher cavity risk: people with recent cavities, dry mouth, braces, or exposed tooth roots. The same holds, to a slightly lesser degree, on WADC water at 0.61 mg/L. The water gives you a partial base layer, and varnish tops it up exactly where a clinician can see it’s needed.
If your cavity risk is low, it’s also reasonable to ask your dentist to walk you through your risk before a treatment — in either direction, the decision should be explained, not automatic.
On a private well? None of this applies automatically
Well water is not fluoridated by any utility
Nobody adjusts the fluoride in a private well — or tests it, unless you do. Well water may carry naturally occurring fluoride, almost none, or more than you’d expect, and taste won’t tell you. This matters in Williamson County and on Fairview’s rural edges, where a home can be minutes from a water main and not connected to it. Test your well water before assuming what’s in it, and tell your dentist you’re on well water so your fluoride plan is built on your actual water, not the city’s.
How to confirm Fairview’s level yourself
Don’t take our word for it — the primary sources are public.
- Read your treating utility’s current water quality report. HVUD’s 2025/26 report lists its average at 0.53 mg/L (range 0.25–0.65 mg/L); the WADC 2025 report (PDF) lists 0.61 mg/L average (range 0.29–0.88 mg/L). A new report comes out each year; the newest one is the one to trust.
- Check CDC’s My Water’s Fluoride. The CDC’s system-by-system tracker at nccd.cdc.gov/DOH_MWF lists fluoridation status and levels for community water systems, including HVUD (TN0000286) and WADC (TN0000191).
- Check whose name is on your bill. If your bill names H.B. & T.S., your water is HVUD water and the 0.53 mg/L average governs your tap. If it names Second South Cheatham UD, that district’s own report is the one to read — we could not verify its figure.

Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below.
Yes — on both supply chains we could verify. Most of Fairview city is served by H.B. & T.S. Utility District, which distributes water treated by Harpeth Valley Utility District (HVUD); HVUD adds fluoride. Dickson-side addresses served by the Water Authority of Dickson County (WADC) also receive fluoridated water. A fourth system, Second South Cheatham Utility District, serves part of the area; we could not verify its fluoride status or level.
It depends on your supply chain. If your water comes from HVUD — through H.B. & T.S. or directly — expect an average of 0.53 mg/L (range 0.25–0.65 mg/L, HVUD 2025/26 report). If you are on WADC water, expect an average of 0.61 mg/L (range 0.29–0.88 mg/L, 2025 report). Both are below the CDC recommended 0.7 mg/L. We could not verify a figure for Second South Cheatham Utility District.
It is below the CDC recommended level of 0.7 mg/L — about three-quarters of it — and this page states that plainly rather than rounding it up. It is still 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.
We don't know, and we won't guess. Second South Cheatham Utility District serves the Kingston Springs / Pegram side of the Fairview area, and we could not retrieve a fluoride figure from its own reporting that we can stand behind. Its current water quality report — or a call to the district — is the reliable route to the number. Until you have it, fluoride toothpaste twice a day remains the main protection either way.
Yes. Fluoridated drinking water is background exposure — it bathes your teeth in a low level of fluoride through the day, which helps, but it does not replace the concentrated fluoride that toothpaste delivers directly to the enamel while you brush. Brush twice a day with fluoride toothpaste, and treat the water as a helpful base layer, not the whole defense.
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 — especially if your water comes from HVUD at 0.53 mg/L, below the CDC recommended level. An in-office fluoride treatment or varnish puts a much stronger dose directly on the teeth, and 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 Williamson 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 treating utility's current water quality report — HVUD's 2025/26 report and WADC's 2025 report are the sources for the two verified levels on this page, and each lists fluoride with its level and range. You can also check CDC's My Water's Fluoride, which tracks fluoridation status and levels by water system. If your bill names H.B. & T.S., HVUD's report is the one that governs your tap.
