Fluoride in Clarksville, TN

It depends on your utility — Clarksville is three systems, not one. The Clarksville Water Department fluoridates: its 2025 report puts fluoride at 0.46 mg/L. Fort Campbell's system also fluoridates, averaging 0.6 mg/L in its 2024 report. Woodlawn Utility District voted in January 2025 to stop adding fluoride, so its water is no longer adjusted.

City water customers: 0.46 mg/L (range 0.38–0.56, 2025 report) — below the CDC recommended 0.7 mg/L, at about two-thirds of it. Fort Campbell: 0.6 mg/L average (range 0.4–0.8, 2024 report) — below the target but close. Woodlawn: no level is published; the district discontinued fluoridation in 2025, so any fluoride in its water now is whatever occurs naturally in its Cumberland River source.

It is low compared to the target. The CDC recommended level is 0.7 mg/L, so the city system's 0.46 mg/L sits at roughly two-thirds of the recommendation — 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.

Woodlawn, which serves about 4,000 households in west Montgomery County, announced in January 2025 that it proposed to stop putting fluoride in its water by January 31, and contemporaneous reporting says its board voted to remove fluoride. Its 2025 water quality reporting publishes no fluoride level. If your bill says Woodlawn, treat your water as not fluoridated — and confirm with the district, which is the authoritative source.

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. If you are on Woodlawn water, toothpaste is carrying the full load now.

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. The city water runs below the CDC recommended level at 0.46 mg/L, Fort Campbell's at 0.6 mg/L, and Woodlawn's is no longer adjusted at all — so in-office fluoride is a reasonable topic for most Clarksville households, and especially for kids and 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 Montgomery 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 — the City of Clarksville's 2025 report and Fort Campbell's 2024 report are linked in the sources below, 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. Woodlawn customers should ask the district directly whether fluoridation has ended and whether any level is published.
