Fluoride in Savannah, TN: is the water fluoridated?
Savannah’s drinking water comes from the Savannah Utility Department, drawn from Memphis aquifer groundwater in Hardin County. The city has a long fluoridation history — but when we pulled the utility’s own published reports, the numbers didn’t agree with each other. This page lays out all of them, exactly as printed, and tells you how to get a current answer.
Savannah has fluoridated its water since December 1969 — but its published figures conflict, and no current figure is verified. The utility’s 2017 and 2018 reports put fluoride at 0.34–0.35 mg/L; its 2020 report prints 2.20 mg/L. No report newer than 2020 could be located, so this page publishes all three figures and picks none.
How this page works: most of our city fluoride pages state one verified level. Savannah’s record doesn’t support that — the source documents disagree. So this page shows the disagreement instead of smoothing it over. If a current Savannah report settles the question, we’ll update this page and note the change.

What the reports actually say
Three Consumer Confidence Reports from the Savannah Utility Department, three fluoride figures. Here is each one with its year and its tested range, taken from the reports themselves.
Tested range: 0.12–0.68 mg/L. A typical, modest fluoridation-era figure — about half the CDC’s recommended level. Read the 2017 CCR (PDF)
Tested range: 0.27–0.35 mg/L. Consistent with the year before — the two reports agree closely with each other. Read the 2018 CCR (PDF)
Tested range: 0.64–2.20 mg/L. As printed, this figure is more than six times the 2017–2018 averages — and above the EPA’s 2.0 mg/L secondary standard. Read the 2020 CCR (PDF)
About that 2020 figure — what we know and what we don’t
The 2020 report’s 2.20 mg/L does not fit the pattern of the two reports before it. We want to be straight about the limits here: there is no verified explanation for the 2020 figure. Nothing in the published record tells us why it reads so much higher, and we won’t guess at a cause. What can be said factually is where it sits against the national benchmarks: as printed, it is above the EPA’s secondary standard of 2.0 mg/L — a non-enforceable guideline aimed at cosmetic effects, mainly enamel fluorosis (tooth discoloration) in children — and below the EPA’s enforceable maximum contaminant level of 4.0 mg/L, the legal limit. It is a discrepancy in the public record that deserves a current answer from the utility — see how to confirm below.
One more gap, stated plainly: no Savannah CCR newer than 2020 could be located. That means Savannah’s current fluoridation status and level are unverified after 2020 — this page will not present any of the three dated figures as what comes out of your tap today.
Savannah’s figures against the national benchmarks
Each Savannah row below is a dated figure from the utility’s own report — not a current measurement. The three benchmark rows are national reference points, and they are three different things: a recommendation, a cosmetic-effects guideline, and a legal limit.
| Figure / benchmark | Fluoride level | What it means |
|---|---|---|
| Savannah — 2017 CCRSavannah Utility Department (TN0000611) | 0.34 mg/L avgRange 0.12–0.68 | The utility’s reported average for 2017 — below the CDC recommended level. |
| Savannah — 2018 CCRSavannah Utility Department (TN0000611) | 0.35 mg/L avgRange 0.27–0.35 | The utility’s reported average for 2018 — consistent with 2017. |
| Savannah — 2020 CCRSavannah Utility Department (TN0000611) | 2.20 mg/L foundRange 0.64–2.20 | The level found as printed in the 2020 report — above the EPA secondary standard, below the enforceable MCL. No verified explanation; no newer report located. |
| 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. |
| EPA secondary standard (non-enforceable) | 2.0 mg/L | A non-enforceable guideline set to protect against cosmetic effects, mainly tooth discoloration (enamel fluorosis) in children. |
| EPA enforceable maximum contaminant level (MCL) | 4.0 mg/L | The legal limit. A system above this is in violation — this is a safety ceiling, not a target. |
Keep the benchmarks distinct: 0.7 mg/L is the CDC recommended level, 2.0 mg/L is the EPA secondary (non-enforceable) standard, and 4.0 mg/L is the EPA enforceable MCL. The 2020 Savannah figure, as printed, sits between the second and third of those — above the cosmetic-effects guideline, below the legal limit. That is a reason to ask the utility for a current report, not a reason to panic about a number from 2020.
How to confirm Savannah’s current fluoride status
The published record stops at 2020. A current answer exists — it just has to come from the utility. Two routes:
- Request the current Consumer Confidence Report from the Savannah Utility Department. Ask the utility for its most recent CCR and look at the fluoride row — that’s where a current tested level would be stated. And ask the direct question alongside it: “Do you still add fluoride to the water?” That one question settles the status, and a current CCR settles the level. No report newer than 2020 could be located publicly, so asking directly is the route that works.
- Check CDC My Water’s Fluoride. The CDC’s database at nccd.cdc.gov/DOH_MWF tracks fluoridation status and levels by water system. Look Savannah up there as a cross-check — and if it ever disagrees with a fresh answer from the utility, trust the utility.
- Confirm which utility is on your water bill first. This page covers the Savannah Utility Department (TN0000611). Households elsewhere in Hardin County may be served by a different system, and its fluoridation status is a separate question with a separate answer. Check the name on the bill, then ask that system.
What to do while the current status is unverified
None of this depends on resolving the conflict. The guidance below holds at any of the three reported levels — and while the current one is unknown.
01 Do you still need fluoride toothpaste?
Yes — regardless of what Savannah’s water currently contains. Drinking water is only background exposure: a low level you sip across the day. Fluoride toothpaste delivers the concentrated dose that does most of the work protecting your teeth. Brush twice a day with fluoride toothpaste; an unverified water status changes nothing about that.
02 The right amount for kids (ADA)
For children under age 3, use a rice-grain smear of fluoride toothpaste. From age 3 and up, a pea-size amount. Supervise brushing, teach kids to spit the toothpaste out, and don’t let them swallow it — these amounts are sized to protect teeth while keeping total fluoride in the safe range.
03 Ask about fluoride varnish
When your water’s fluoride level can’t be confirmed, you can’t count on the tap to supply a known amount. On that basis, professional fluoride varnish at checkups is a sensible safeguard to discuss — it makes sure your teeth are covered whatever the water turns out to contain, and it’s especially worth raising for kids and anyone who is cavity-prone. It’s a judgment call to make with your dentist, based on your family’s cavity risk.
04 On a private well? Test, don’t assume
Well water is never fluoridated by a utility — a private well isn’t part of the Savannah Utility Department system at all. Well water drawn from the same aquifer country can carry some naturally occurring fluoride, but the only way to know your level is a water test. Test before assuming your well contains fluoride, and don’t start fluoride supplements for anyone in the household without a test result and a dentist’s or pediatrician’s input.

Questions people actually ask
Asked the way people actually ask them — answered from the sources cited below, including where the honest answer is “the records conflict and the current figure isn’t verified.”
Historically, yes. The CDC’s Fluoridation Census records Savannah fluoridating since December 1969, and the Savannah Utility Department’s own water quality reports list fluoride in every year we could find. But whether fluoride is still added today is unverified: no Savannah Consumer Confidence Report newer than 2020 could be located, so there is no current, confirmed answer. The utility can give you one — ask for its current CCR and ask directly whether fluoride is still added.
The Savannah Utility Department’s 2020 Consumer Confidence Report prints a fluoride level found of 2.20 mg/L, with a range of 0.64–2.20 mg/L. As printed, that figure sits above the EPA’s secondary standard of 2.0 mg/L — a non-enforceable guideline about cosmetic effects like tooth discoloration — and below the EPA’s enforceable maximum contaminant level of 4.0 mg/L. It also conflicts sharply with the 0.34 and 0.35 mg/L averages in the 2017 and 2018 reports. There is no verified explanation for the 2020 figure, and we won’t invent one. We publish it exactly as printed, alongside the earlier figures.
We don’t pick one, because the documents don’t let us. Each figure comes from the utility’s own report for a different year: 0.34 mg/L average in 2017, 0.35 mg/L average in 2018, and a 2.20 mg/L level found in 2020. The first two are close to each other; the third is not, and nothing in the published record explains the jump. What we can say is that none of the three is a current figure — the newest report we could locate is from 2020.
Ask the source. Request the current Consumer Confidence Report from the Savannah Utility Department and look at the fluoride row — and ask directly whether fluoride is still added to the water. You can also check the CDC’s My Water’s Fluoride database at nccd.cdc.gov/DOH_MWF, which tracks fluoridation by water system. If the two ever disagree, trust the utility’s current report.
Yes. Drinking water is only background exposure — a low level you sip across the day — while fluoride toothpaste delivers the concentrated dose that does most of the work protecting your teeth. That holds whatever Savannah’s current water level turns out to be. Brush twice a day with fluoride toothpaste. For children, the ADA recommends a rice-grain smear of toothpaste under age 3 and a pea-size amount for ages 3 and up, with an adult supervising, teaching them to spit, and making sure they don’t swallow it.
It’s worth raising at your next checkup. Because Savannah’s current water status is unverified, you can’t count on the tap to supply a known level of fluoride — and professional fluoride varnish is a low-cost way to make sure your teeth are covered either way, especially for kids and anyone who is cavity-prone. It’s a judgment call to make with your dentist based on your family’s cavity risk, not a conclusion about Savannah’s water.
No. Well water is never fluoridated by a utility — a private well isn’t connected to the Savannah Utility Department system at all, and nobody treats it for you. Well water can carry some naturally occurring fluoride, but you can’t assume it does, or how much. Get the water tested before assuming it contains fluoride, and don’t start fluoride supplements for anyone in the household without a test result and a dentist’s or pediatrician’s input.

Method in one line: Savannah’s own CCRs publish three fluoride figures that do not agree (2017: 0.34 mg/L average; 2018: 0.35 mg/L average; 2020: 2.20 mg/L level found), and no report newer than 2020 could be located — so this page publishes all three, dated, picks none, and labels Savannah’s current status unverified rather than present any dated figure as today’s level.
