Fluoride in Milan, TN: is the water fluoridated?
Milan historically adjusted its water — the CDC Fluoridation Census records it adjusting since March 1951 — but its recent reports tell a different story than the target. Milan Public Utilities Authority’s own reports show fluoride falling steadily: 0.67 mg/L in 2021, 0.51 mg/L in 2023, 0.39 mg/L on average in 2024, and 0.36 mg/L in 2025 — well below the CDC’s 0.7 mg/L recommendation, and the recent reports contain no statement that fluoride is added. Here’s the documented series, how it stacks up, and what it means for your toothpaste, your kids, and your dentist visits.
Milan’s most recent reported fluoride level is 0.36 mg/L (2025 report) — roughly half the CDC-recommended 0.7 mg/L, after a steady multi-year decline in the utility’s own reports. Milan historically adjusted its water, but its recent reports show levels well below the fluoridation target and contain no statement that fluoride is added, so current practice is not stated in the reports. Either way, you still need fluoride toothpaste: the water is background protection, not a substitute for brushing — and at this level, that background is thinner than the target assumes.
How this page works: every figure below traces to the utility’s own reports or a federal benchmark, cited at the bottom. One heads-up: Milan city water is one system among several in this part of Gibson County — if your water bill names a different utility, its fluoride status may differ. Here’s how to tell.

Milan’s fluoride, in one card
Milan’s drinking water is supplied by Milan Public Utilities Authority. It’s groundwater, drawn from the Memphis aquifer, serving about 10,716 people. Milan has a long fluoridation history — the CDC Fluoridation Census records the system as adjusting since March 1951 — but read the utility’s recent reports closely and the levels have been sliding for years, with no statement in them that fluoride is added. What follows is exactly what those reports document, no more and no less.
| Utility | Milan Public Utilities Authority |
|---|---|
| Source water | Groundwater — Memphis aquifer |
| People served | About 10,716 |
| Fluoridation status | Historically adjusted — CDC Fluoridation Census: adjusting since March 1951. Recent reports show levels well below the fluoridation target and contain no statement that fluoride is added; current practice is not stated in the reports. |
| Most recent level | 0.36 mg/L (2025 report; range 0.31–0.41 mg/L) |
| Documented series | 2021 report: 0.67 mg/L (range 0.40–0.67) · 2023 report: 0.51 mg/L (0.39–0.63) · 2024 report: 0.39 mg/L average (0.31–0.49) · 2025 report: 0.36 mg/L (0.31–0.41) |
One page, one system
These figures describe Milan Public Utilities Authority customers. Gibson County Municipal Water Districts #4 and #5 and other small systems serve surrounding county addresses, and their fluoridation status is their own. Check your water bill to confirm which system serves your address before assuming Milan’s numbers are yours.
How 0.36 mg/L compares
Start with what Milan’s reports actually document — a steady decline across four report years. Then set the most recent figure against the three federal numbers that get quoted in the fluoride debate. They answer three different questions: what level should a system aim for, where do cosmetic effects become a concern, and what’s the legal ceiling? Milan’s current level sits below all three.
| Report | Fluoride level | Reported range |
|---|---|---|
| 2021 report | 0.67 mg/L | 0.40–0.67 mg/L |
| 2023 report | 0.51 mg/L | 0.39–0.63 mg/L |
| 2024 report | 0.39 mg/L average | 0.31–0.49 mg/L |
| 2025 report | 0.36 mg/L | 0.31–0.41 mg/L |
| System / benchmark | Fluoride level | What it means |
|---|---|---|
| Milan Public Utilities Authority | 0.36 mg/L | The most recent level, from the utility’s 2025 report — down from 0.67 mg/L in the 2021 report. |
| CDC recommended level | 0.7 mg/L | The level the U.S. Public Health Service recommends systems target for cavity prevention with minimal fluorosis risk. Milan’s current level is roughly half of it. |
| EPA secondary standard | 2.0 mg/L | A non-enforceable guideline set to protect against cosmetic effects, mainly tooth discoloration (fluorosis) in children. Not a safety limit and not a target. |
| EPA enforceable maximum (MCL) | 4.0 mg/L | The legal limit. A system above this is in violation — this is a safety ceiling, not a goal. |
Read it this way: 0.7 mg/L is the recommended target, 2.0 mg/L is a non-enforceable cosmetic-effects guideline, and 4.0 mg/L is the enforceable legal maximum. Milan’s 0.36 mg/L is well below the target — this is a story about too little fluoride for the cavity-prevention goal, not too much.
About the wider fluoride debate
You’ve probably seen the arguments — fluoride has been debated for decades, and recent research discussion has mostly centered on exposures well above the levels U.S. systems aim for. We won’t pretend the debate doesn’t exist, and we won’t inflate it either: Milan’s current reported level of 0.36 mg/L is below the level federal health agencies recommend, so the practical question here runs the other direction — how much protection a lower-than-target supply actually provides. For the full picture — how fluoride works, who benefits most, and the fluoride-free question — see our flagship guide: Fluoride: what it does, who needs it, and the fluoride-free question.
A low-fluoride supply doesn’t replace toothpaste — it makes it matter more
This is the part people most often get backwards. Fluoride in tap water and fluoride in toothpaste aren’t duplicates — they do different jobs, and the toothpaste is doing the heavier one. That’s doubly true when the water itself is running at about half the recommended level.
Water is background; toothpaste is the main event
Drinking water with fluoride in it keeps a low level of fluoride in your mouth through the day. That helps, but it’s background exposure — and at Milan’s reported 0.36 mg/L, it’s roughly half the background the CDC’s 0.7 mg/L recommendation is designed to provide. Fluoride toothpaste delivers a much higher concentration directly onto your teeth, twice a day — that’s the dose that does most of the cavity-fighting work. Skipping fluoride toothpaste because “it’s in the water” gives up the stronger protection, and in Milan the water’s share is smaller than most people assume.
The right amount for kids (ADA)
For children under age 3, use a rice-grain smear of fluoride toothpaste. From age 3 on, a pea-size amount. The amounts are small on purpose: young kids swallow toothpaste, and these amounts protect teeth while keeping a child’s total fluoride intake in the right range.
In-office fluoride and varnish
Worth a real conversation in Milan — more so than in a town at the 0.7 mg/L target. With tap water at about 0.36 mg/L, the background protection your teeth get between brushings is lower, so the concentrated fluoride applied in the dental chair fills more of a gap. If you or your kids are cavity-prone (recent fillings, dry mouth, braces, a pattern of decay), varnish is a genuinely useful add-on here, not an upsell. If you rarely get cavities, it’s a closer call, and an honest dentist will tell you so rather than sell it as mandatory for everyone. Ask which camp you’re in, and why.
What about fluoride-free toothpaste?
It exists, and people choose it for their own reasons — that’s your call. Just make it with open eyes: giving up fluoride toothpaste means giving up the single most proven cavity-prevention tool in the bathroom cabinet, and Milan’s below-target water level doesn’t make up the difference. Our flagship fluoride guide walks through the fluoride-free question in full.
On a private well outside Milan?
Different situation entirely. Private well water is not adjusted — nobody adds fluoride to it, and the city system’s fluoride doesn’t reach it. Whatever fluoride a well contains is whatever occurs naturally in the groundwater, and that varies from well to well.
Test before you supplement
If you’re on a well and unsure of your fluoride level, get the water tested — it’s the only way to know. Don’t start fluoride supplements for anyone in the household, especially kids, without a test result and a dentist’s or pediatrician’s input. Too little fluoride means missed protection; too much carries its own problems, and the right amount depends entirely on what’s already in your water.
How to confirm Milan’s fluoride level yourself
Don’t take our word for it — the sources behind this page are public, and checking them takes a few minutes. One thing the public record can’t settle for you: whether Milan still adds fluoride today. For that, go straight to the utility.
- Read the utility’s water quality reports. Every year, Milan Public Utilities Authority publishes a water quality report (its Consumer Confidence Report). The documented series on this page comes from those reports: 0.67 mg/L in 2021, 0.51 mg/L in 2023, 0.39 mg/L average in 2024, and 0.36 mg/L in 2025. Ask the utility for the current year’s report and you’re reading the same documents we did. Note what the recent reports do not contain: any statement that fluoride is added.
- Ask Milan Public Utilities Authority directly whether it still adds fluoride. The reports document the levels but don’t state current practice, and the levels alone can’t tell you whether the decline reflects a change in treatment or something else. A direct question to the utility is the only way to get a current, on-the-record answer.
- Check CDC My Water’s Fluoride and the Fluoridation Census. The CDC’s My Water’s Fluoride database tracks fluoridation status and levels by water system, and the CDC Fluoridation Census is the source that records Milan as adjusting since March 1951 — a useful federal cross-check on the history.
- Confirm which system actually serves your address. Your water bill names your utility. If it says Gibson County Municipal Water District #4 or #5, or another small system, you’re not on Milan city water — ask that system for its report and its fluoride status instead.
Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below.
Milan historically adjusted its water — the CDC Fluoridation Census records Milan as adjusting since March 1951. But its recent reports show levels well below the fluoridation target and contain no statement that fluoride is added: 0.67 mg/L in the 2021 report, 0.51 mg/L in 2023, 0.39 mg/L average in 2024, and 0.36 mg/L in 2025. Current practice is not stated in the reports, so the honest answer is: historically adjusted, recent levels low, and whether Milan still adds fluoride today is a question to ask Milan Public Utilities Authority directly.
No — it’s about half the level public health agencies aim for. The CDC recommendation is 0.7 mg/L. Milan’s most recent reported level, 0.36 mg/L in the 2025 report, sits well below that recommendation, well below the EPA’s secondary standard of 2.0 mg/L (a non-enforceable guideline about cosmetic tooth discoloration), and far below the EPA’s enforceable legal maximum of 4.0 mg/L. Those benchmarks answer different questions — target, cosmetic guideline, and legal ceiling — and Milan’s current level is below all three.
Yes — and at Milan’s current level it matters more, not less. Fluoride in water is background exposure — a low level in your mouth through the day — and at 0.36 mg/L Milan’s water is providing roughly half the background the CDC’s 0.7 mg/L recommendation is designed to deliver. Fluoride toothpaste is the main event: it delivers a much higher concentration directly to your teeth, twice a day. For kids, the ADA recommends a rice-grain smear of fluoride toothpaste under age 3 and a pea-size amount from age 3 on.
With Milan’s water at about 0.36 mg/L — roughly half the CDC-recommended level — in-office fluoride or varnish fills more of a gap than it would in a community at the 0.7 mg/L target, because the background protection from your tap water is lower. It’s especially worthwhile if you’re cavity-prone — recent fillings, dry mouth, braces, a history of decay — since it delivers a concentrated dose exactly where it’s needed. If you rarely get cavities, it’s still a reasonable conversation to have with your dentist rather than an automatic yes or no. A good dentist will explain which camp you’re in and why.
No. Private well water is not adjusted — nobody adds fluoride to it, and whatever fluoride it contains is whatever occurs naturally in the groundwater. If you’re unsure of your level, get the water tested. Don’t start fluoride supplements for anyone in the household without a test result and a dentist’s or pediatrician’s input, because the right amount depends on what’s already in your water.
Read Milan Public Utilities Authority’s annual water quality reports — they’re the utility’s own published reports, and they’re where the documented series on this page comes from: 0.67 mg/L in 2021, 0.51 mg/L in 2023, 0.39 mg/L average in 2024, and 0.36 mg/L in 2025. Note that the recent reports document the levels but contain no statement that fluoride is added, so to learn whether Milan still adds fluoride today, ask Milan Public Utilities Authority directly. You can also check the CDC’s My Water’s Fluoride database and its Fluoridation Census, which records Milan as adjusting since March 1951. And check your water bill first: Gibson County Municipal Water Districts #4 and #5 and other small systems serve surrounding county addresses, so confirm which system actually serves your home before assuming Milan’s numbers are yours.
