Purple toothpaste is an argued-about corner of the whitening aisle: it took off on TikTok (by July 2023 the trade magazine Cosmetics & Toiletries counted more than 96 million views), dentists keep pointing out it isn’t whitening, and the most-reviewed product in our lineup 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. It masks yellow tone for about an hour in the one trial that measured it, rather than changing your actual tooth shade the way a complete peroxide system does; for that, see our guide to the best at-home teeth whitening kits. 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 we drew on, 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 practical complaint that recurs in community threads and in Amazon’s review summaries.
- 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, built mostly on lab studies and focused on adolescents and young adults, 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 improvement was reported up to the 30-minute reading, while the yellowness reduction was still measurable at 60 minutes, the study’s last time point; nothing was measured beyond an hour. 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 the one clinical trial 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 a community thread 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 | V34 is a final step after normal brushing; MOON and SAKYPRORAL brush on like toothpaste, but add 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 a pigment-first product for events, the second row’s products 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 tone result in this category comes from serum-style products (the V34 trial and the systematic review’s test formulations). Whether a drugstore paste’s purple 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)
Best for: Making purple a daily habit without giving up fluoride or stain removal
- Anticavity 0.243% sodium fluoride formula per its FDA drug listing
- 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; one early Reddit report of a dry, gritty mouthfeel came from Crest's separate two-piece Brilliance kit, not this purple paste
- −The tone effect of a purple paste is unmeasured: every measured purple result comes from serum-style products

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 paste’s tone effect is unmeasured (the trial data all come from serum-style products), so treat it as a possible 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, Euthymol and the Colgate, or want to avoid added dyes entirely, this isn’t the tube for you.
Key Features
- 0.243% sodium fluoride (0.15% w/v fluoride ion) anticavity formula
- Surface-stain removal (up to 100% more surface stains than regular toothpaste, per Crest) with a 24-hour stain-prevention claim
- Three 4.6 oz tubes per pack
Hismile V34 Colour Corrector: Most-Reviewed Pick
Hismile V34 Colour Corrector
Best for: A pigment-first instant purple effect for an event in the next hour
- The most-reviewed pick in this lineup, 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
- +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 sensitivity in the one clinical trial 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
- −Amazon's review summary and a Reddit user report the purple tinting gums, lips, tongue and cheeks, so rinse carefully

Why We Recommend It
V34 is the most-reviewed purple product in this lineup by a wide margin, and the only 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 improvement was reported up to the 30-minute reading, 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 said Hismile’s powder version “actually does work” as a mask for stains 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: a Reddit user described the pigment staining the inside of the mouth, tongue, cheeks and lips, and Amazon’s review summary flags purple on gums and lips, 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 (3 Pack, 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 $6.70 a tube in the three-pack we link
- 4.5 stars across nearly 3,000 reviews
- +Among the cheapest per tube in this lineup, about $6.70 a tube in the three-pack
- +Fluoride formula with micro-polishing stain removal, so it works as your only toothpaste
- +4.5 stars across nearly 3,000 reviews; in this lineup, the three fluoride pastes out-rate the three fluoride-free picks
- −Its tone effect is unmeasured, so expect a subtle effect at most rather than a dramatic before-and-after
- −Colgate gives no abrasivity (RDA) figure for this paste on its listing, and we found none published elsewhere

Why We Recommend It
If you’re purple-curious, this is the lowest-stakes entry point: a full-size fluoride toothpaste from Colgate at about $6.70 a tube, sold as a three-pack. 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. Amazon’s review summary is mixed on the purple itself, with some buyers loving the color and others finding it wasn’t what they wanted, so treat the tone effect as a bonus rather than the reason to buy.
One buying note: this pick is the three-pack, which keeps the per-tube cost down if the purple sticks as a habit; if you only want to test it, a 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 bold signature mint and a fluoride base
- Violet tone-up formula with titanium dioxide brighteners
- Sodium fluoride paste per its FDA drug listing
- Signature bold mint flavor, per Euthymol
- +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
- +Markets an instant violet tone-up after one use, per its listing
- −Amazon's review summary is mixed on irritation, with some buyers reporting burning, and one user report in our research described mouth irritation after switching to a Euthymol whitening variant
- −At around $15 for one 3.7 fl oz tube, it costs about 2.2 times as much per tube as the Colgate three-pack

Why We Recommend It
Euthymol is a brand with British heritage going back to 1898, per its listing (the purple paste is made by Korea’s LG H&H), 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), marketed on an “instant violet tone-up” after one use. Its label pairs Blue 1 and Red 33 with titanium dioxide, the same pigment trio as the Colgate, and 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 listing calls it a “signature bold mint” and advertises freshness for up to 12 hours, and Amazon’s review summary is mixed on irritation, with some buyers reporting burning sensations. 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 fl oz tube it’s drugstore-formula pricing at import-brand markup—about 2.2 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 fl 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 (just over 200) and a 3.7-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 reaching about 92% stain removal after the equivalent of roughly 128 ordinary brushings. Two caveats from the paper itself: the hydroxyapatite paste it tested was Dr. Kurt Wolff’s Bioniq Repair Whitening, not MOON’s, set against Unilever’s blue covarine Signal White Now, and three of its four authors are employees of Dr. Kurt Wolff, the company that makes the tested paste.
It also solves a format problem: MOON’s is a brush-on paste with papain enzyme, and its listing says that unlike messy purple serums it “activates into a gentle purple foam while brushing.” The trade-offs are the category’s usual ones plus one more—a 3.7-star rating on a small (just over 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 Fluoride-Free Paste
SAKYPRORAL Purple Toothpaste (3.88 oz)
Best for: Testing a fluoride-free purple paste 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 lowest purchase price 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 4.0-star rating on about 450 reviews and no community track record we could find
- −Fluoride-free, so using it as your only paste means giving up fluoride's cavity protection
(Affiliate link) · Free shipping on eligible Prime items
Why We Recommend It
SAKYPRORAL earns the last slot as the budget path into fluoride-free purple. 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. Its listing describes a purple paste that lathers into a white foam and is brushed on twice a day, not a serum.
The caveats are bigger here than anywhere else in this lineup. This is a small direct-to-consumer brand: its 4.0-star rating sits on about 450 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 a purple paste that also carries fluoride, 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, brushed on twice a day per its listing
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 wanted purple toothpaste to last about six hours, until their graduation was over; 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 V34 serum is 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 practical complaint that recurs in community threads and in Amazon’s review summaries. Serum-style products are built around the pigment, and they draw the staining complaints in community threads. Brush gently, keep it off your lips, and rinse thoroughly. If a purple-free sink matters to you, SAKYPRORAL’s listing says its paste lathers white and leaves no purple residue on teeth, tongue or sink.
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 get underneath 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, reported the lightness improvement up to its 30-minute reading and the yellowness reduction still present at the study’s 60-minute endpoint, its last measurement. 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 no significant enamel erosion across the included studies, and sensitivity under 3% in its one clinical trial. 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 practical complaint that recurs in community threads and in Amazon’s review summaries for V34 and the Crest paste. Apply thin layers, keep it off your lips, and rinse thoroughly. For what it’s worth, SAKYPRORAL’s listing claims a white lather that leaves no purple residue on your teeth, tongue or sink.
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; other dentists in the thread doubted the toothpaste was the cause, pointing instead to cementation, the lab, or the tooth underneath. The cautious play with any recent restoration: ask the dentist who placed it before adding any pigmented cosmetic product.
