Fluoride in Morristown’s water: what the 2023 report shows
Morristown’s water report carries a fluoride number that lands almost exactly on the CDC’s recommended level — but it’s a 2023 number, with a wide spread behind it, and no newer utility statement to stand on. Here’s the figure, the fine print, and how to check the current status yourself.
The short answer
Morristown’s most recent available report — its 2023 Consumer Confidence Report — shows fluoride averaging 0.675 mg/L, near the CDC-recommended 0.7 mg/L, with individual results ranging from 0.02 to 0.83 mg/L. That’s consistent with a system that adjusts fluoride — but no newer utility statement was available to confirm today’s status, so read 0.675 as a 2023 figure, not a current one.
How this page works: every local fluoride figure below comes from Morristown Utilities System’s 2023 Consumer Confidence Report — the most recent report with a fluoride row we could obtain. Where the evidence stops, this page says so plainly instead of rounding a 2023 measurement up into a claim about today.

- Status, stated honestly
- A measured average of 0.675 mg/L is consistent with a system that adjusts fluoride to a target — natural water at that level, that close to the CDC’s 0.7 mg/L recommendation, would be a coincidence. But we could not find a current utility statement explicitly confirming the practice today. So the verified fact on this page is the dated 2023 level; anything about today’s status rests on that report until a newer one is published.
The numbers: Morristown (2023) vs. the benchmarks
One local figure, three reference points. Keep them separate — the recommendation, the cosmetic guideline, and the legal ceiling are three different things, and they get mixed up constantly.
| System / benchmark | Fluoride level | What it means |
|---|---|---|
| Morristown Water System2023 Consumer Confidence Report | 0.675 mg/L averageRange: 0.02–0.83 mg/L | The reported 2023 average sits essentially at the CDC’s recommended level — but it’s an average of results that swung widely, and it describes 2023, not today. |
| CDC recommended levelU.S. Public Health Service / CDC, since 2015 | 0.7 mg/L | The target for systems that adjust fluoride — judged to prevent cavities while keeping fluorosis risk low. A recommendation, not a law. |
| EPA secondary standard (SMCL)EPA, not federally enforceable | 2.0 mg/L | A guideline aimed at preventing tooth discoloration (fluorosis) in children. Systems above it must notify the public. This is a cosmetic-effects standard, not the legal limit — don’t confuse it with the 4.0 mg/L MCL below. |
| EPA maximum contaminant level (MCL)EPA, enforceable | 4.0 mg/L | The legal ceiling for fluoride in public drinking water, set to protect against bone and severe tooth damage — applies whether fluoride is added or natural. Morristown’s highest reported 2023 result, 0.83 mg/L, is nowhere near it. |
Read the range honestly: 0.675 mg/L is an average, not a steady level. The individual 2023 results behind it ran from 0.02 mg/L — essentially no fluoride at all — up to 0.83 mg/L. Morristown blends Cherokee Lake / Holston River surface water with Havely’s Spring groundwater, and blends and source conditions shift over a year. The 2023 average looks right on target; any given sample may not have been. That variability is exactly why the next section matters.
What this means for your family’s routine
Whatever the current level turns out to be, the practical advice doesn’t change much — because the water was never the main source of fluoride protection in the first place.
Yes You still need fluoride toothpaste
Water is background exposure — a low level passing over your teeth whenever you drink. Toothpaste is the main event: a much higher concentration applied directly to the teeth, twice a day. In Morristown that distinction matters more than most places, because the reported 2023 results swung from 0.02 to 0.83 mg/L — toothpaste delivers the same dose regardless of which way the water level swung that month. Don’t drop the toothpaste on the strength of a water average.
Kids Amounts by age, per the ADA
From the first tooth until age 3: a smear the size of a grain of rice. From age 3 up: a pea-size amount. Brush twice a day, have an adult load the brush while kids are young, and teach them to spit, not swallow. The amounts — not avoidance — are how fluorosis risk is managed while teeth are forming.
Ask In-office fluoride and varnish
The concentrated treatment painted on at a checkup is aimed at people whose cavity risk runs high: recent cavities, dry mouth, braces, exposed roots, a history of decay that keeps coming back. For a high-risk patient it’s genuinely worthwhile — it’s extra armor where the routine isn’t holding. For a low-risk patient it’s closer to optional. If it’s offered at every visit and you don’t know why, ask “What risk factor are we treating?” — a good answer names something specific about your mouth, not a policy about everyone’s.

Live near Morristown, but not on Morristown water?
City limits and water-system boundaries are not the same map. A Morristown mailing address does not guarantee Morristown water — and the systems around Morristown each make their own treatment decisions.
Check the name on your water bill
- Bean Station Utility District buys Morristown water, so its fluoride follows this system — the figures on this page describe the water Bean Station delivers, too.
- Other area systems are separate — Witt Utility District, Newport Utilities, White Pine, and others each treat (or buy) their own water. Morristown’s 2023 figure says nothing about theirs.
- The utility named on your water bill is the one whose Consumer Confidence Report holds your fluoride answer. If it isn’t Morristown Utilities, start there instead.
On a private well in Hamblen County?
Well water is not adjusted — test if you’re unsure
If your home is on a private well, none of the above applies to you. No utility blends, adjusts, tests, or reports on well water — that’s the well owner’s job. Natural fluoride in groundwater varies widely: some wells have almost none, some land near the recommended level, and a few naturally run high.
So the order of operations matters: have the water tested by a certified laboratory first (your county health department can point you to one), then take the result to your child’s dentist or pediatrician. Supplements are recommended only when the water is low in fluoride, in a dose matched to the measured level and the child’s age — and testing is also the only way to catch the opposite problem, natural levels high enough to risk fluorosis. Never dose on a guess, in either direction.
How to confirm the current status
This page’s one real limitation is the age of its central figure. Here’s how to close that gap yourself — both routes go to primary sources, not summaries like this one.
- Read Morristown Utilities’ newest Consumer Confidence Report. The 2023 report is the document behind every number on this page — fluoride at 0.675 mg/L, range 0.02–0.83 mg/L. Ask Morristown Utilities for its newest report and look for the fluoride row: that row, whenever it’s published, supersedes the 2023 figures here.
- Check the CDC’s My Water’s Fluoride. The CDC’s lookup at nccd.cdc.gov/DOH_MWF tracks the fluoridation status of U.S. water systems. States and systems report to it voluntarily and it isn’t real-time, so if it ever disagrees with a fresh Consumer Confidence Report, trust the report.
- Ask the utility directly. A short call or email to Morristown Utilities — “Do you currently adjust fluoride, and what was the most recent reported level?” — gets you the one thing this page couldn’t find in print: a current statement in the utility’s own words.
Questions Morristown residents ask us
The best evidence we have says the system was adjusting fluoride as of its 2023 report — but we want to be precise about what is and isn’t confirmed. Morristown Water System’s 2023 Consumer Confidence Report, the most recent report with a fluoride row we could obtain, reports fluoride averaging 0.675 mg/L. An average that close to the CDC’s 0.7 mg/L target is consistent with a system that adds fluoride. What we could not find is a current utility statement explicitly confirming the practice today, so this page reports the dated 2023 level as the verified fact and does not claim to know today’s status.
Because the 2023 Consumer Confidence Report from Morristown Utilities System is the most recent report with a fluoride row we could obtain. Utilities publish these reports annually, and a newer Morristown report may exist — but until we can read its fluoride row ourselves, we won’t guess at its numbers. When a newer report is available, this page will be updated and the date on the figure will change with it.
Because 0.675 mg/L is an average, not a single reading. The individual results behind it in the 2023 report ran from 0.02 mg/L — essentially no fluoride at all — up to 0.83 mg/L. Morristown blends surface water from Cherokee Lake and the Holston River with groundwater from Havely’s Spring, and blend ratios, source conditions, and treatment all shift over a year. The honest takeaway: the 2023 average sat right at the CDC’s recommended level, but any given sample could be well below it. That’s why we print the range everywhere we print the average.
Yes. Water and toothpaste do different jobs: drinking water is background exposure — a low level passing over your teeth during the day — while toothpaste is the main event, a concentrated dose applied directly to the teeth twice a day. That matters extra in Morristown, where the reported 2023 results swung from 0.02 to 0.83 mg/L: toothpaste doesn’t depend on which way the water level swung that month. Per the ADA, use a smear the size of a grain of rice for children under 3 and a pea-size amount from age 3 up, and teach kids to spit, not swallow.
By the published benchmarks, the 2023 average sits in the zone regulators aim for: essentially at the CDC’s recommended 0.7 mg/L, roughly a third of the EPA’s 2.0 mg/L secondary standard (a non-enforceable guideline about tooth discoloration in children), and far below the EPA’s enforceable maximum of 4.0 mg/L. Even the highest individual 2023 result, 0.83 mg/L, is below all of those reference points except the recommendation itself. People disagree about fluoridation policy, and reasonable questions exist — but on the numbers in the 2023 report, Morristown’s level was nowhere near any limit.
Two routes. First, Morristown Utilities’ newest Consumer Confidence Report — ask the utility for its latest report and look for the fluoride row; that’s the document that supersedes the 2023 figures on this page. Second, the CDC’s My Water’s Fluoride lookup, which tracks fluoridation status for U.S. water systems. If the two ever disagree, trust the utility’s newest report — it’s the primary source, and the CDC database depends on systems reporting to it.
