Fluoride in Dandridge, TN water
Dandridge doesn’t treat its own water — it buys finished water from three neighboring systems and blends them. All three fluoridate, but each runs at a different level, so the honest answer for your tap depends on which source feeds your street.
Yes, Dandridge’s water is fluoridated — because all three systems it buys water from fluoridate: Jefferson City, Knoxville Utilities Board (KUB), and Newport Utilities. But there is no single Dandridge fluoride level. In 2025 those sources ran from 0.26 mg/L to 0.57 mg/L, so your level depends on which source feeds your street.
Why no single number? Dandridge’s own 2025 Consumer Confidence Report publishes no fluoride row for its blended water. Rather than invent a blend, this page gives you the three verified source levels.

Three sources, three different levels
Dandridge Water Management Facility (TN0000170) buys finished water from Jefferson City, KUB, and Newport Utilities. The CDC Fluoridation Census classifies all three as adjusted systems — meaning they add fluoride — and have for decades: Newport since January 1965, Jefferson City since December 1966, and KUB since January 1974. What each one actually delivered in 2025 is a different story.

Source levels are 2025 figures from each system’s own reporting (Jefferson City’s as republished in Dandridge’s 2025 CCR; KUB and Newport from their own 2025 reports). Newport publishes a detected level, not an average — 0.548 mg/L detected, with a reported range of 0.47–0.77 mg/L. mg/L is the same unit as parts per million (ppm).
One honest wrinkle: Jefferson City runs low
Jefferson City fluoridates — but its 2025 average of 0.26 mg/L is well below the CDC’s 0.7 mg/L target, and its range touches 0.00. Levels drift over time even in systems that add fluoride. That drift is exactly why a Dandridge home fed mostly by Jefferson City water can’t count on the tap alone for cavity protection, while a home fed by Newport water may sit at or above the target. Same town, same utility bill — different water.
What this means for your teeth
Because your home’s level could sit anywhere in that source range — and could shift if the blend shifts — the water is the variable. Your daily routine is the constant you control.
01 Toothpaste is the constant
Brush twice a day with fluoride toothpaste, whatever your street’s source. Fluoridated water keeps a low level of fluoride in your mouth through the day; toothpaste delivers the concentrated dose. In a three-source town like Dandridge, toothpaste is the one layer that never changes.
02 Kids: use the ADA amounts
For children under 3, a rice-grain smear of fluoride toothpaste. From age 3, a pea-size amount. Brush morning and night, encourage spitting, and don’t rinse it all away — the fluoride keeps working after the brush stops.
03 Ask about varnish
If you or your child are cavity-prone, fluoride varnish is worth a conversation at your next visit. It’s a concentrated coating painted on at dental or medical visits, and it makes the most sense precisely where water levels are uncertain — which describes Dandridge’s blend.
04 On a private well?
None of this applies to you. Wells aren’t fluoridated, and natural fluoride varies from well to well. Get your water tested for fluoride, then ask your dentist what — toothpaste, varnish, supplements — fits the number you actually have.
How to confirm your own water
Two routes — and one honest caveat about the first.
- Read Dandridge’s Consumer Confidence Report. The 2025 CCR (PDF) confirms Dandridge buys its water from Jefferson City, KUB, and Newport Utilities — but know going in that it publishes no fluoride row for Dandridge’s blended water. You won’t find your number in it.
- Ask the utility which source supplies your address. That’s the missing piece only Dandridge Water Management Facility can give you. Once you know your source, the table above tells you its 2025 level and range.
- Check CDC’s My Water’s Fluoride. The CDC’s lookup at nccd.cdc.gov/DOH_MWF tracks fluoridation status by system — a good cross-check on the three source systems and their adjusted (fluoridating) classification.

Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below.
Yes. Dandridge Water Management Facility (TN0000170) does not treat its own water — it buys finished water from Jefferson City, Knoxville Utilities Board (KUB), and Newport Utilities. The CDC Fluoridation Census classifies all three as adjusted (fluoridating) systems: Jefferson City since December 1966, KUB since January 1974, and Newport since January 1965. So the water Dandridge delivers is fluoridated — via its suppliers.
Because Dandridge blends water from three different systems, and each system runs at a different level. In 2025, Jefferson City averaged 0.26 mg/L, KUB averaged 0.57 mg/L, and Newport Utilities reported 0.548 mg/L detected. Dandridge’s own 2025 Consumer Confidence Report publishes no fluoride row for its blended distributed water, so no single honest number exists. Your home’s level depends on which source is feeding your street.
Dandridge’s Consumer Confidence Report does not publish a street-by-street source map, and the blend can shift. The only way to know is to ask Dandridge Water Management Facility which source supplies your address. Even then, treat the answer as which supply you mostly get, not a guarantee your level never changes.
Yes — especially in Dandridge, where your water level could sit anywhere in the source range and one source averages well below the CDC target. Fluoridated water keeps a low level of fluoride in your mouth through the day, but toothpaste delivers the concentrated dose that does most of the protective work. Brush twice a day with fluoride toothpaste, and for children use a rice-grain smear under age 3 and a pea-size amount from age 3, per the ADA.
It is worth asking about. Because Dandridge’s level varies by source — and Jefferson City’s supply averages 0.26 mg/L, well under the CDC’s 0.7 mg/L target — children who are prone to cavities may not be getting steady protection from the tap alone. Fluoride varnish, applied at dental or medical visits, is a standard extra layer for cavity-prone kids. Ask your child’s dentist whether it makes sense for them.
Private wells are not fluoridated by anyone, and natural fluoride in well water varies — it can be low, at target, or occasionally high. If your home is on a well, this page’s source levels do not apply to you. Have your well water tested for fluoride so you and your dentist know what you are actually getting, and ask about fluoride toothpaste, varnish, or supplements based on the result.

Method in one line: Dandridge publishes no blended fluoride figure, so this page reports only the three source systems’ own verified 2025 numbers — no blended level was calculated, estimated, or invented.
