Purple toothpaste is the most argued-about product in the whitening aisle: TikTok made it famous, dentists keep pointing out it isn’t whitening, and the biggest name in the category holds a 3.5-star rating across seventy-three thousand reviews. Both sides are right. Purple pigment produces a real, measurable, and temporary optical effect—think makeup for your teeth, not treatment—and whether that’s a scam or exactly what you need depends entirely on what you’re buying it for. We compared six purple toothpastes and correctors on the evidence, and if what you actually want is whitening that lasts, start with our best whitening strips guide instead.
How We Evaluated Purple Toothpastes
We compared product listings, ingredient panels and FDA drug-facts filings, live Amazon ratings and review counts, and the peer-reviewed evidence on color correctors against real user discussions—19 Reddit threads cited in our research brief, spanning r/askdentists, r/Dentistry, and general subs. We did not lab-test the products.
We scored each pick across five criteria:
- Truth in what it claims: products marketed as temporary color correction scored above products implying bleach-level whitening they can’t deliver.
- Formula beyond the pigment: fluoride and cavity protection, stain-removal ingredients (silica, enzymes, hydroxyapatite), and whether it can replace your regular toothpaste or only supplement it.
- Strength of the optical effect: serum-style correctors are built around the pigment, where drugstore pastes add it to a toothpaste base; we matched each to the use case it fits.
- Mess and staining: purple dye that tints lips, cheeks, and tongues is the category’s most common practical complaint in community threads—and it marks sinks too.
- Value: cost per tube against how the product is meant to be used—daily paste versus event-day cosmetic.
What purple toothpaste actually does (in 30 seconds)
The mechanism is color theory. Violet sits opposite yellow on the color wheel, so a film of violet pigment on the tooth surface visually cancels yellow undertones—the same trick as purple shampoo for brassy hair. A 2025 systematic review of peroxide-free color correctors found they produce a color change just past the threshold where the eye can perceive it—visible, but well short of the change carbamide peroxide bleaching produces.
Two more numbers worth knowing before you buy:
- The effect is measured in minutes, not days. The one randomized controlled trial on a purple corrector—a Hismile-funded study of V34, with Hismile employees among the authors—measured an immediate improvement of about three shades from a single application; the lightness effect faded by the 30-minute mark, while the yellowness reduction was still measurable at 60 minutes, the study’s last time point. Community estimates run from an hour to overnight, but the measured window is short. Plan your application around the photo, not the day.
- Nothing is bleached. No peroxide, no change to the tooth itself. That cuts both ways: sensitivity in trials of these products stayed under 3%, and per the ADA’s whitening guidance, changing the tooth’s own color—intrinsic stain—takes a chemical bleaching reaction, most commonly carbamide or hydrogen peroxide. When the pigment rinses away, your teeth are the color they were.
One caveat raised in community threads and echoed by a dentist’s blog: purple over yellow doesn’t produce white, it produces less-yellow—overdo the pigment and teeth can read slightly gray. A thin, even application beats a heavy one.
The real decision: fluoride paste or cosmetic serum?
Nobody’s ads mention this, but the six products below split into two different product types:
| Type | Products | What it is | How to use it |
|---|---|---|---|
| Purple fluoride toothpaste | Crest, Colgate, Euthymol | A normal anticavity toothpaste with violet pigment added | Replaces your regular toothpaste |
| Purple cosmetic corrector | Hismile V34, MOON, SAKYPRORAL | A fluoride-free serum or paste built around the pigment | A final step after normal brushing (MOON’s paste can stand alone, but adds no fluoride) |
If you just want a daily toothpaste that leans your smile cooler-toned, buy from the first row and you give up nothing. If you want the strongest instant effect for events, the serums in the second row are built around the pigment effect—but they don’t protect against cavities, so they supplement a fluoride routine rather than replace it.
One caution no ad will give you: every measured result in this category comes from serum-style products—the V34 trial and the systematic review’s test formulations. Whether a drugstore paste’s milder pigment load produces a visible tone effect at all hasn’t been measured. Treat the paste-format purple as a bonus on top of a working toothpaste, not the reason to buy.
Crest 3D White Brilliance Luminous Purple — Editor’s Pick
Crest 3D White Brilliance Luminous Purple Toothpaste (3-pack)

- Crest 3D White stain-removal base with violet pigment on top
- Three 4.6 oz tubes — about $6.30 per tube
- +Highest Amazon rating in this lineup at 4.6 stars across 3,000+ reviews
- +Anticavity fluoride formula — it replaces your regular toothpaste instead of adding a step
- +Three 4.6 oz tubes work out to about $6.30 per tube
- −Uses FD&C Red 40 + Blue 1 dye — a single early report in our research described a gritty mouthfeel from the Brilliance line
- −The purple tint is subtler than serum-style correctors, so the instant camera-ready effect is milder

Why We Recommend It
Crest’s Luminous Purple is our top pick because it resolves the category’s core problem: it doesn’t ask you to trade anything for the purple. Per its FDA drug-facts listing it’s a 0.243% sodium fluoride anticavity toothpaste, built on the 3D White stain-removal base, with the violet pigment layered on top. Brush with it twice a day and you get cavity protection, surface-stain polishing, and the purple pigment layer in one step—no separate serum, no fluoride gap (with the caveat above: the paste-format tone effect itself is unmeasured).
The 4.6-star rating across more than 3,000 reviews is the highest in this lineup, and it’s not hard to see why: buyers of a roughly $19 three-pack of Crest expect toothpaste and get good toothpaste, while buyers of a $15 serum promising transformation often leave disappointed. At about $6.30 per tube it’s priced like a premium drugstore whitening paste, because that’s what it is.
Two limits. The pigment load is milder than a serum’s, so the instant effect is a subtle tone shift, not a party trick. And its purple comes from FD&C Red 40 with Blue 1—if you prefer the Red 33 dye pair used by Hismile and Euthymol, or want to avoid added dyes entirely, this isn’t the tube for you.
Key Features
- 0.243% sodium fluoride (0.16% w/v fluoride ion) anticavity formula
- Micro-polishing surface stain removal with 24-hour stain-prevention claim
- Three 4.6 oz tubes per pack
Hismile V34 Colour Corrector — The Original
Hismile V34 Colour Corrector
Best for: The strongest instant purple effect for an event in the next hour
- The serum that created the category, with 73,000+ Amazon reviews
- The only pick in this lineup with a randomized controlled trial we could find
- Peroxide-free, fluoride-free final-step serum
- +The category-defining product, with by far the largest review base here (73,000+)
- +A manufacturer-funded randomized trial measured a real, if temporary, shade improvement from one use
- +Peroxide-free and gentle — sensitivity in trials of this product class stayed under 3%
- −Its 3.5-star rating is the lowest in this lineup — largely buyers who expected lasting whitening from a product whose measured effect was only tracked for an hour
- −Community reports describe the purple pigment tinting lips, tongue, and cheeks if you don't rinse carefully

Why We Recommend It
V34 is the product that made purple toothpaste a category, and it remains the definitive serum-style corrector here. It’s also the only pick here with a randomized controlled trial we could find: a 2024 study—funded by Hismile, with company employees among the authors, which we weight accordingly—measured an immediate improvement of about three shades from a single application; the lightness effect faded by 30 minutes, while the yellowness reduction held to the study’s final 60-minute time point. That’s the most precise duration data anywhere in this category, and it’s the reason our advice is to apply V34 right before the photos, not at breakfast.
The 3.5-star rating has a structure worth reading before you buy. Look through the review base and the pattern from our community research repeats: people who bought an illusion knowingly rate it well—one r/askdentists user described it as working exactly as claimed, as a mask rather than a stain remover—while people who expected whitening report no difference after days of use and rate it one star. The product didn’t change between those two reviews; the expectations did—and Hismile’s own before-and-after marketing did plenty to set them.
The recurring practical complaint is mess: community threads describe the pigment tinting lips, tongue, and cheek tissue when applied heavily, something the before-and-after ads don’t show. Use a thin layer, brush gently, and rinse well.
Key Features
- Serum-style corrector applied like toothpaste as a final step
- FD&C Blue 1 + D&C Red 33 pigment pair, peroxide-free and fluoride-free
- Applied as a thin layer after normal brushing
Colgate Optic White Purple — Best Value
Colgate Optic White Purple Toothpaste (4.2 oz)
Best for: Trying the purple category for the price of a regular tube of toothpaste
- Fluoride anticavity formula with micro-polishing stain removal
- About $6 for a full-size 4.2 oz tube
- 4.5 stars across nearly 3,000 reviews
- +The cheapest way into the category in this lineup at under $6
- +Fluoride formula with micro-polishing stain removal, so it works as your only toothpaste
- +4.5 stars across nearly 3,000 reviews — drugstore purples rate far better than serum purples
- −Mild purple pigment load, so expect a subtle tone effect rather than a dramatic before-and-after
- −No published abrasivity (RDA) figure we could find for this SKU, so how gentle the micro-polishing is can't be independently verified

Why We Recommend It
If you’re purple-curious, this is the lowest-stakes entry point: a full-size fluoride toothpaste from one of the biggest names in oral care for under $6. Like the Crest, it’s a real anticavity paste—Colgate markets the line on removing surface stains via micro-polishing, with the violet pigment aiming at the tone effect—so the worst case is that you bought a decent whitening toothpaste and the purple did less than TikTok promised.
Its 4.5-star average across nearly 3,000 reviews backs up the same pattern we saw with Crest: when purple comes as a bonus on top of a functioning toothpaste, buyers are satisfied. The pigment level is modest, which cuts both ways—less instant drama than a serum, but also less risk of the lip-and-sink staining that dogs the heavier correctors.
One buying note from our price checks: Colgate’s 3-packs worked out modestly cheaper per tube than this single listing, so if the purple sticks as a habit, the bundle is the better buy. The single tube is the low-commitment way to find out.
Key Features
- Fluoride anticavity formula (Optic White line)
- Micro-polishing surface stain removal
- 4.2 oz tube, vegan and sugar-free per Colgate’s listing
Euthymol Purple — Boldest Flavor
Euthymol Purple Whitening Toothpaste
Best for: Purple color correction with Euthymol's famously intense signature flavor and a fluoride base
- Violet tone-up formula with titanium dioxide brighteners
- Sodium fluoride paste per its FDA drug listing
- Signature intense Euthymol flavor
- +Fluoride paste (per its FDA drug listing), so it stands in for your daily toothpaste
- +4.2 stars across 1,400+ reviews — strong for this category
- +Titanium dioxide plus violet pigments aim the formula at a stronger tone-up than a typical drugstore purple
- −The intense signature flavor is divisive — one user report in our research described mouth irritation after switching to a Euthymol whitening variant
- −At around $15 for one 3.7 oz tube, it costs about 2.5 times as much per tube as the Colgate

Why We Recommend It
Euthymol is the British pharmacy brand with a devoted cult following, and its Purple sits in an interesting middle spot: a fluoride toothpaste per its FDA drug listing (so it belongs in the daily-paste row of our table), but with a formula aimed at a heavier tone-up than the Crest or Colgate—violet pigments plus titanium dioxide—though no head-to-head measurement of pigment strength exists. Its 4.2 stars across 1,400+ reviews make it the third-best-rated pick in this lineup.
The flavor is the deciding factor. Euthymol’s signature intense flavor—“bold mint” by its own listing’s description—is beloved by its cult following and, for plenty of others, simply too much; the brand advertises freshness that lasts up to 12 hours, and the strength backs that up. Our community research also logged one user reporting mouth irritation after switching to a Euthymol whitening variant—a single unresolved report we mention for completeness, but if you have a sensitive mouth, the flavor intensity alone may decide this for you before the pigment does.
At around $15 for a single 3.7 oz tube it’s drugstore-formula pricing at import-brand markup—about 2.5 times the Colgate per tube. You’re paying for the bolder formula aim and the Euthymol experience.
Key Features
- Sodium fluoride paste (FDA drug listing) with violet pigment + titanium dioxide
- 24-hour stain-defense marketing claim
- 3.7 oz tube
MOON Purple — Best Fluoride-Free
MOON Purple Toothpaste (Fluoride-Free Hydroxyapatite)
Best for: A fluoride-free routine that wants an enamel-native mineral alongside the purple effect
- Hydroxyapatite for enamel support plus papain enzyme for stains
- Foaming paste format — no serum mess
- Vegan, SLS-free, sold at Ulta
- +Hydroxyapatite plus papain enzyme — in a 2025 lab study, hydroxyapatite toothpaste removed surface stain at least as well as optical-pigment paste
- +Foams like a normal toothpaste instead of a messy serum
- +Vegan, SLS-free formula sold at Ulta as well as Amazon
- −No fluoride, so it trades away cavity protection — pair it with a fluoride product if you're cavity-prone
- −A smaller review base (around 200) and a 3.8-star rating, with the usual expectation-gap complaints
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
MOON’s purple is the pick for readers already committed to a fluoride-free routine, because it’s the only product here that pairs the pigment with hydroxyapatite—the mineral tooth enamel is made of, and one we cover in depth in our hydroxyapatite toothpaste guide. The stain-removal side has real lab support: a 2025 in-vitro study brushing stained enamel found hydroxyapatite toothpaste removed surface stain at least as well as an optical-pigment comparator, with both converging around 92% stain removal at a full brushing time.
It also solves a format problem: unlike the serum correctors, MOON’s is a foaming paste with papain enzyme that behaves like normal toothpaste in the mouth and sink. The trade-offs are the category’s usual ones plus one more—a 3.8-star rating on a small (around 200) review base, the familiar expectation-gap complaints, and no fluoride. Our community research turned up a skeptical “does it actually work” thread and no substantive answer, so the summary stands: a solid formula on paper with a thin real-world track record so far.
Key Features
- Hydroxyapatite + papain enzyme, fluoride-free and SLS-free
- Color Correct Pro violet pigment system, with papain enzyme handling surface stains
- 4.2 oz foaming paste, vegan
SAKYPRORAL Purple — Budget Serum
SAKYPRORAL Purple Toothpaste (3.88 oz)
Best for: Testing a stronger serum-style purple effect for around $10
- Dual-enzyme formula: papain + dextranase alongside the pigment
- Peroxide-free and fluoride-free
- About $10 for 3.88 oz
- +About $10 for a 3.88 oz tube — the cheapest serum-style option in this lineup
- +Dual-enzyme formula targets surface stains while the pigment handles tone
- +Peroxide-free and marketed for sensitive teeth
- −A small direct-to-consumer brand with a 3.8-star rating and no community track record we could find
- −Fluoride-free and meant as a final step after brushing, not a toothpaste replacement
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
SAKYPRORAL earns the last slot as the budget path to a serum-strength purple effect. At about $10 for a 3.88 oz tube it costs roughly a third less than V34, and its formula adds two enzymes—papain and dextranase—aimed at surface stains alongside the color-correcting pigment.
The caveats are bigger here than anywhere else in this lineup. This is a small direct-to-consumer brand: its 3.8-star rating sits on 311 reviews, our forum research found no community discussion of it at all in the subs we searched, and its stain-removal claims rest on the manufacturer’s description rather than independent data. Treat it as a low-cost experiment—reasonable at $10 in a way it wouldn’t be at $25. If you want the pick with the deepest track record instead, that’s the V34 above; if you want independent evidence, that’s the Crest or Colgate.
Key Features
- Papain + dextranase dual-enzyme formula with purple pigment
- Peroxide-free, fluoride-free, marketed for sensitive teeth
- 3.88 oz tube, final-step application
Buyer’s Guide: Getting What You Actually Paid For
Wondering how dental professionals see purple toothpaste? Our community research covers 137 whitening threads from Reddit's dental subs, where the consistent professional line is that pigment masks tone temporarily and peroxide is what changes tooth shade.
Use it like makeup, because that’s what it is
The measured effect window is roughly an hour. Apply a thin layer as your final step right before the moment you care about—photos, interview, date—rather than with breakfast expecting it to last until dinner. In our community research, one r/askdentists poster planned purple toothpaste around a six-hour graduation ceremony; based on the trial data, even that is optimistic. Thin and even also matters because heavy purple over yellow reads gray, not white.
Decide the fluoride question first
If purple toothpaste replaces your regular toothpaste, the fluoride split matters more than the pigment. The Crest, Colgate, and Euthymol are anticavity fluoride pastes; the Hismile, MOON, and SAKYPRORAL are not, and the serum-style products are designed as an extra step after brushing anyway. The expensive mistake nobody in the community threads even flags—which is exactly why we flag it—is quietly swapping a fluoride toothpaste for a cosmetic corrector and losing cavity protection without noticing. If you’re deliberately fluoride-free, MOON’s hydroxyapatite formula is the pick built for you.
Expect the mess
The recurring theme: purple pigment tints lips, tongue, and cheeks—the category’s most common practical complaint in community threads—and it will mark your sink too. Serum-style products are built around the pigment, and they draw the staining complaints in community threads. Brush gently, keep it off your lips, rinse thoroughly, and rinse the sink while you’re at it.
If you have veneers, bonding, or crowns, ask your dentist first
Manufacturers market color correctors as safe for dental work, and because nothing is bleached that’s broadly plausible. But our research surfaced a case reported by a dentist on r/Dentistry of purple pigment appearing to stain around a patient’s veneers—other dentists in the thread disputed that a toothpaste could penetrate a properly sealed margin, and the likelier reading is that the case says more about cement margins than about pigment. Still, restorations are expensive; a quick question at your next cleaning costs nothing.
Know when you’ve outgrown it
If you keep reaching for the purple because you want your teeth actually whiter, you want peroxide, not pigment. The ADA’s whitening overview covers the evidence on bleaching; Mayo Clinic’s guidance notes OTC whitening options are generally safe used as directed and results are not permanent. Our whitening strips and whitening kit guides cover the products that change shade for weeks, not minutes. And one boundary worth knowing before spending anything: purple pigment only counters yellow. If your discoloration reads gray or comes from within the tooth—tetracycline staining, fluorosis, an aging or injured tooth—pigment can’t help, OTC peroxide often can’t either, and the productive next step is a conversation with your dentist about in-office options.
FAQ
Does purple toothpaste actually whiten teeth?
No—and the distinction matters for your wallet. Purple pigment temporarily cancels yellow undertones on the tooth surface, the way purple shampoo tones brassy hair. A 2025 systematic review found the color change from peroxide-free correctors just crosses the threshold of visibility, versus the far larger change from peroxide bleaching. Nothing about the tooth itself is whitened.
How long does the purple effect last?
The only randomized trial data, from a Hismile-funded study of V34, measured the lightness effect fading by 30 minutes and the yellowness reduction still present at the study’s 60-minute endpoint. Community estimates range from an hour to overnight, but rinsing, drinking, and saliva remove the pigment film—plan around minutes-to-hours, not days.
Is purple toothpaste safe?
The evidence so far says yes for the category as a whole: the 2025 systematic review reported sensitivity under 3% and no significant enamel erosion across the included studies. The purple comes from cosmetic dyes—typically FD&C Blue 1 paired with D&C Red 33 or FD&C Red 40. Individual sensitivities to strong flavors or specific formulas do occur; our research logged isolated, unresolved irritation reports, so stop using any product that irritates your mouth and see your dentist if it persists.
Will it stain my lips or mouth?
It can—mouth and lip tinting is the category’s most common real complaint in community threads, especially with heavily pigmented serums. Apply thin layers, keep it off your lips, and rinse thoroughly. The pigment rinses off skin and tissue; sink grout takes more scrubbing.
Purple toothpaste or whitening strips—which should I buy?
They do different jobs. Purple toothpaste is instant, temporary tone correction for a moment; whitening strips use peroxide to change actual tooth shade over days to weeks, which is the approach dental professionals in our research consistently pointed to for lasting results. If you want both, use strips for the baseline and purple for event days.
Can I use purple toothpaste with veneers or bonding?
Manufacturers generally market it as safe on dental work, since nothing is bleached. One disputed case in our research involved pigment and a patient’s veneers, with dentists attributing it to a sealing problem rather than the toothpaste. The cautious play with any recent restoration: ask the dentist who placed it before adding any pigmented cosmetic product.
