Fluoride in White House, TN
White House is a one-utility town: White House Utility District treats Old Hickory Lake water for every customer. Its verified level sits a hair below the national recommendation.
White House’s water is fluoridated — just below the CDC target. White House Utility District, the town’s only utility, reported 0.649 mg/L in 2025 (range 0.46–0.90 mg/L) — about 93% of the CDC recommended 0.7 mg/L, close but not rounded up. It is far below both EPA standards.
How this page works: the level below comes from WHUD’s own published water quality report, not from a marketing claim or a guess — and an independent database (EWG, 0.61 ppm) agrees with it. New to the topic? Start with our full fluoride guide.

White House’s fluoride, by utility
Everything on this page traces back to these facts, from each utility’s own published water quality report.
LEVEL Fluoride in WHUD water
0.649 mg/L
Range 0.46–0.90 mg/L, WHUD 2025 Water Quality Report. Just below the CDC recommended 0.7 mg/L — about 93% of it, stated plainly.
STATUS Fluoridated — adjusted
The report lists fluoride’s source as “water additive that promotes strong teeth.” EWG’s independent record for the district (0.61 ppm) agrees with the utility’s own figure.
UTILITY White House Utility District
PWSID TN0000745. Serves about 104,872 people — Tennessee’s largest water utility district — and it is the only utility serving White House.
SOURCE Old Hickory Lake
WHUD treats Old Hickory Lake (Cumberland River reservoir) surface water at its own plant — one system, one level, district-wide.
How White House’s levels compare
A number by itself doesn’t tell you much. Here is White House’s level next to the three benchmarks that matter, each labeled for exactly what it is.
| Benchmark | Level | How White House compares |
|---|---|---|
| White House UD, 2025 | 0.649 mg/L | Range 0.46–0.90 mg/L. Just below the CDC recommended level — we won’t round it up to the target. |
| CDC recommended level | 0.7 mg/L | WHUD runs at about 93% of this; its reported range straddles the target. |
| EPA secondary (non-enforceable) standard | 2.0 mg/L | Far below this guideline, which is aimed at preventing cosmetic effects like tooth discoloration. |
| EPA enforceable maximum contaminant level (MCL) | 4.0 mg/L | Far below the legal limit. |
EWG’s Tap Water Database record for WHUD (0.61 ppm) is an independent cross-check, not the source of the headline figure — the published level is the utility’s own 0.649 mg/L.
One town, one utility, one number
White House has the simplest fluoride picture in this series: a single district (TN0000745) treating a single source for every address in town. If your bill says White House Utility District, the 0.649 mg/L above is your number. If it names any other utility, you are outside the district and on a different system.
Do you still need fluoride toothpaste?
Yes — 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.
So even in a fluoridated town — and White House is one, at 0.649 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 White House’s 0.649 mg/L — close to the CDC recommended level, but below it — 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 nearly complete 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 on the rural edges of Robertson and Sumner Counties, where a home can sit inside WHUD’s service area and not be 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 district’s.
How to confirm White House’s level yourself
Don’t take our word for it — the primary sources are public.
- Read WHUD’s current water quality report. The 2025 report booklet (PDF) lists fluoride at 0.649 mg/L (range 0.46–0.90 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 WHUD (TN0000745).
- Check whose name is on your bill. White House addresses on public water are WHUD customers; if your bill names anyone else, that utility’s report governs your tap.

Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below.
Yes. White House Utility District (WHUD) treats its own water from Old Hickory Lake and adds fluoride. WHUD's 2025 water quality report puts the level at 0.649 mg/L, with a range of 0.46–0.90 mg/L. That is just below the CDC recommended level of 0.7 mg/L.
About 0.65 mg/L (the report's figure is 0.649 mg/L), with results ranging from 0.46 to 0.90 mg/L across the year — so individual readings straddle the CDC target even though the reported level sits just below it. White House is a single-utility town: every WHUD customer gets this same water. EWG's independent record for the district, 0.61 ppm, agrees.
It is just barely low — about 93% of the CDC recommended level of 0.7 mg/L — and this page states that plainly rather than rounding it up. It 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 with fluoride toothpaste covers the small remaining gap.
Yes — WHUD is one system with one treatment plant (Old Hickory Lake water), serving 104,872 people across Robertson, Sumner, and northern Davidson counties, the largest water utility district in Tennessee. The 0.649 mg/L figure is the district's own reported level, so it describes White House, Portland, Millersville, and Gallatin-area WHUD customers alike. If your bill names a different utility, you are on a different system.
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. White House's water at 0.649 mg/L is close to but below the CDC recommended level, so the water alone is not quite the full story. 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.
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 Robertson or Sumner 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.
