Fluoride in Crossville, TN
Crossville’s own water department treats two lakes at two plants, and sells water to two neighboring districts. Its fluoride runs at about half the CDC target — here is the per-plant record.
Crossville’s water is fluoridated — at about half the recommended level. The Crossville Water Department adjusts fluoride at both its plants, averaging 0.34 mg/L at Holiday Hills and 0.32 mg/L at Meadow Park (2024 report; range under 0.15–0.42 mg/L) — below the CDC recommended 0.7 mg/L, and far below both EPA standards.
How this page works: the levels below come from the City of Crossville’s own published water quality report, plant by plant, not from a marketing claim or a guess. Crossville treats its water at two separate plants, and the report gives each plant’s average — so this page does too, rather than blending them into a number the utility never published.

Crossville’s fluoride, by plant and utility
Everything on this page traces back to these facts, from the City of Crossville’s Water Quality Report for 2024.
LEVEL Holiday Hills plant
0.34 mg/L average
Range across both plants <0.15–0.42 mg/L in 2024. Below the CDC recommended 0.7 mg/L — about half of it.
LEVEL Meadow Park plant
0.32 mg/L average
The Meadow Park plant treats the larger share of Crossville’s water. Its average is also below the CDC recommended level, stated plainly.
STATUS Fluoridated — adjusted
The report lists fluoride’s source as “Water additive to promote strong teeth” — Crossville adjusts fluoride at both plants. South Cumberland UD and Grandview UD buy Crossville-treated water, so this level describes their taps too.
UTILITY Six utilities serve the Crossville area
Crossville Water Dept. (TN0000150, ~31,973 served) is the hub. Crab Orchard UD (TN0000147, ~21,011) treats its own water; South Cumberland UD (TN0000159, ~11,786) and Grandview UD purchase Crossville water; West Cumberland UD (TN0000557, ~5,546) buys from Bon De Croft UD; Pikeville WS (TN0000551, ~5,346) uses groundwater.
SOURCE Holiday Hills Lake & Meadow Park Lake
Crossville relies on surface water from Holiday Hills Lake and Meadow Park Lake, treated at the plant of the same name on each lake.
How Crossville’s levels compare
Crossville publishes two plant averages, not one — so the table carries both, next to the three benchmarks that matter, each labeled for exactly what it is.
| Benchmark | Level | How Crossville compares |
|---|---|---|
| Crossville WD — Holiday Hills plant, 2024 | 0.34 mg/L avg | One of the city’s two treatment plants. Below the CDC recommended level. |
| Crossville WD — Meadow Park plant, 2024 | 0.32 mg/L avg | Combined range across both plants: <0.15–0.42 mg/L. |
| CDC recommended level | 0.7 mg/L | Both Crossville plants run below this — at roughly half of the recommendation. We won’t round them up to the target. |
| EPA secondary (non-enforceable) standard | 2.0 mg/L | Crossville is far below this guideline, which is aimed at preventing cosmetic effects like tooth discoloration. |
| EPA enforceable maximum contaminant level (MCL) | 4.0 mg/L | Crossville is far below the legal limit. |
Crossville’s level has come down over time: its 2009 report showed plant averages of 0.87 and 0.93 mg/L. The 2024 report above is the one that describes today’s water.
Cumberland County is not one water system
Crossville Water Department’s level describes its own customers plus South Cumberland UD and Grandview UD, which buy its water. It does not describe Crab Orchard UD (its own source), West Cumberland UD (buys Bon De Croft water), or Pikeville WS (groundwater, in Bledsoe County) — we could not verify fluoride figures for those three systems, and this page won’t guess them. Check your water bill for your utility’s name before assuming this page’s numbers are your numbers.
Do you still need fluoride toothpaste?
Yes — and this is the point people most often get backwards.
Yes — and at about half the recommended level in the water, toothpaste is carrying more of the load here than in a city at the target. 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.
So even in a fluoridated city — and Crossville is one, at roughly 0.32–0.34 mg/L — 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.
At Crossville’s roughly 0.32–0.34 mg/L — about half 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 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 across Cumberland County and the Cumberland Plateau, where plenty of homes sit outside the city system. 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 Crossville’s level yourself
Don’t take our word for it — the primary sources are public.
- Read the City of Crossville’s current water quality report. The 2024 report (PDF) lists fluoride by plant — 0.34 mg/L average at Holiday Hills and 0.32 mg/L at Meadow Park. 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 Crossville Water Department (TN0000150).
- Check whose name is on your bill. If your bill names Crab Orchard UD, West Cumberland UD, or Pikeville WS, that system’s own report governs your tap — not this page’s Crossville figures.

Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below.
Yes. The Crossville Water Department adjusts fluoride at both of its treatment plants — Holiday Hills and Meadow Park — and its 2024 water quality report lists fluoride's source as a water additive to promote strong teeth. South Cumberland Utility District and Grandview Utility District buy Crossville-treated water, so their customers receive the same fluoridated water.
The City of Crossville's Water Quality Report for 2024 gives an average of 0.34 mg/L at the Holiday Hills plant and 0.32 mg/L at the Meadow Park plant, with a combined range of under 0.15 to 0.42 mg/L across the year. The report publishes the two plant averages separately, so this page does too rather than blending them.
It is below the recommended level — about half of it. The CDC recommended level is 0.7 mg/L, so Crossville's plant averages of 0.32–0.34 mg/L sit well below the target, and this page states that plainly rather than rounding up. The level is nowhere near the EPA limits — the enforceable maximum contaminant level (MCL) is 4.0 mg/L and the secondary (non-enforceable) standard is 2.0 mg/L. Brushing twice daily with fluoride toothpaste covers the rest of what your teeth need.
It depends on the name on the bill. If it names South Cumberland Utility District or Grandview Utility District, yes — both buy Crossville-treated water. If it names Crab Orchard Utility District, West Cumberland Utility District, or Pikeville Water System, no — those systems treat or buy water from other sources, and we could not verify their fluoride levels. Check your bill and read the utility named on it.
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. Crossville's water at roughly 0.32–0.34 mg/L is about half the CDC recommended level, so the water alone is only a partial base layer. 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 Cumberland 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 the City of Crossville's current water quality report — the 2024 report is linked in the sources below, and fluoride is listed by plant with its averages 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 a utility district other than Crossville, South Cumberland, or Grandview, that district's report is the one that governs your tap.
