Citeeth White Premium, Double Mint — Three Stain Agents, Two Fluorides, and What "Whitening" Really Means
Overview
Citeeth White Premium is Daiichi-Sankyo's stain-removal toothpaste, and Daiichi-Sankyo is a pharmaceutical company rather than a household-goods brand, which shows in how the formula is built: three separate agents attacking the stain film by three different routes, with fluoride underneath so the product does the ordinary job at the same time.
Double Mint is the colder of the two flavours in this range. It pairs peppermint and spearmint for a sharp, bracing finish — the mint most people mean when they say a toothpaste tastes clean. If you want something gentler and more herbal, the Sweet Herb Mint version of the same formula is the other choice, and the only difference between the two products is the flavour.
That is worth saying plainly, because until today the two SKUs carried word-for-word identical descriptions and gave a customer nothing to choose on.
How it lifts stain, which the old page never explained. Daiichi-Sankyo builds this around three stain agents working together rather than one abrasive doing all the work: sodium polyphosphate, which chelates and loosens the mineral bonds holding the stain film to enamel; PEG-8 (macrogol 400), a solvent for the fatty and tarry components of that film — the same class of agent that does the work in a smoker's paste; and polyvinylpyrrolidone, which keeps the loosened pigment dispersed in the foam so it rinses away instead of resettling. There is also α-TCP as a polishing agent, which leaves the surface smoother and therefore slower to pick the stain back up. That combination is why this works on the brown film at the gum line that a plain paste polishes around.
Two fluorides, and the figure we will not invent. Daiichi-Sankyo formulates this with both sodium fluoride and sodium monofluorophosphate. The two release fluoride on slightly different timescales, which is a common and sensible approach in Japanese pastes. Japan's ceiling for an over-the-counter toothpaste is 1450 ppm and this product sits within it, but Daiichi-Sankyo does not publish the exact figure in the material we hold and we are not going to print one that looks authoritative. Ask us before ordering if you need the number and we will read it off the carton. What matters for the decision: unlike a pure stain paste, this one does protect against decay, so it can be your everyday toothpaste.
What "whitening" means on a Japanese toothpaste, because it is not what you think. Japanese whitening pastes — ホワイトニング — work by lifting and dispersing the stain film that sits on the outside of the enamel: the brown that coffee, tea, red wine and tobacco leave behind. They do this with polishing agents and with chemical dispersants such as polyphosphates and PEG. They contain no peroxide, and they do not and cannot change the natural colour of the tooth underneath, because that colour is dentine showing through translucent enamel and nothing applied for two minutes and rinsed off will reach it. So: if your teeth are stained, this will make them visibly lighter, sometimes strikingly so. If your teeth are clean and simply not as white as you would like, no Japanese toothpaste will change that, and anyone selling you one on that promise is selling you a disappointment. That is a bleaching treatment and it comes from a dentist.
On the wording we removed. In Japan this is a 医薬部外品 — a quasi-drug — a middle category between a cosmetic and a medicine, with a fixed list of phrases a manufacturer is licensed to print. Translated literally into English those phrases become medicinal claims that are not approved anywhere else, which is how our pages ended up saying things like "therapeutic toothpaste", "kills pathogenic bacteria" and "prevention of periodontitis". A toothpaste sold as a cosmetic in the EU cannot claim to treat gum disease. We have replaced that language with what the product does mechanically and chemically, which is less impressive-sounding and considerably more useful.

Who Is This For?
- Right for you if you have visible stain — from coffee, tea, red wine or tobacco — and want it lifted rather than polished around.
- Right for you if you want one paste that does both jobs. This carries fluoride, so unlike a pure stain product it can be your only toothpaste.
- Right for you if you want a cold, sharp mint. Double Mint is the more bracing of the two; Sweet Herb Mint is the gentler one.
- Not for you if your teeth are clean and you want their natural colour lightened. That is bleaching, this is not bleaching, and no Japanese toothpaste is.
- Not for you if you get recurrent mouth ulcers and have identified SLS as your trigger — ask us to check the pack before you order.
- Not for you if you are buying it as a child's paste. This is an adult-strength fluoride formulation.
How to Use
- Use it as your normal toothpaste, twice a day. Unlike a pure stain paste, this one contains fluoride, so it does the everyday job as well.
- A pea-sized amount on a soft brush. More paste does not clean better; it only foams more.
- Brush for two minutes over all surfaces, spending the extra time at the gum line where stain concentrates.
- Light pressure. The stain agents here are chemical, not just mechanical — pressing harder does not help them work.
- Spit, do not rinse. Rinsing with water washes the fluoride off before it has done anything.
- Give it four to six weeks before judging the stain result. Chemical stain removal is gradual, not a single-brushing effect.
- Do not brush within thirty minutes of citrus, wine, vinegar or fizzy drinks.
- Replace the brush every three months, or sooner if the bristles splay — a worn brush undoes most of this.
Frequency: Twice daily as your normal toothpaste. The old card said "several times a day", which is unnecessary — twice is what the evidence supports, and a third brushing adds abrasion rather than protection.
Full Ingredients
Daiichi-Sankyo publishes the functional composition. The parts that decide whether this product suits you:
- Fluorides: sodium fluoride and sodium monofluorophosphate
- Stain agents: sodium polyphosphate, PEG-8 (macrogol 400), polyvinylpyrrolidone
- Antibacterial: cetylpyridinium chloride (CPC)
- Gum ingredient: glycyrrhizic acid
- Polishing agent: α-TCP
Flavour: Double Mint. Peppermint and spearmint together, cold and sharp. Nothing in the flavour choice changes the active formula — the Sweet Herb Mint version is chemically the same product with a softer, more herbal profile.
What is not published, and what we will not guess. Daiichi-Sankyo does not print the fluoride ppm figure in the material available to us, nor an RDA value, nor the full excipient list including the foaming agent. Most Japanese pastes in this class use sodium lauryl sulfate; if you are avoiding SLS because of recurrent mouth ulcers, ask us and we will photograph the ingredient panel before you order rather than tell you what is probably in it. The manufacturer does not publish an RDA (relative dentin abrasivity) figure for this paste, so we cannot tell you how abrasive it is, and we have removed the old page's claim that it "does not damage tooth enamel". Any stain-removing paste works partly by abrasion. Use a soft brush, light pressure, and do not brush within thirty minutes of anything acidic.
Cautions
- Children of six and under: a pea-sized amount only, brushing supervised by an adult, and encourage spitting rather than rinsing or swallowing. If your child takes fluoride from another source — drops, tablets or fluoridated water — ask a dentist before using an adult-strength paste.
- Adult-strength fluoride formulation. Not intended as a children's toothpaste.
- The manufacturer does not publish an RDA (relative dentin abrasivity) figure for this paste, so we cannot tell you how abrasive it is, and we have removed the old page's claim that it "does not damage tooth enamel". Any stain-removing paste works partly by abrasion. Use a soft brush, light pressure, and do not brush within thirty minutes of anything acidic.
- The full excipient list, including the foaming agent, is not published in the material we hold. If you avoid SLS because of recurrent mouth ulcers, ask us to check the pack before you order.
- Twice a day is enough. The old card said several times a day; a third brushing adds abrasion without adding protection.
- Do not brush within thirty minutes of citrus, wine, vinegar or fizzy drinks. Softened enamel plus any toothpaste is the actual route to enamel wear.
- Contains glycyrrhizic acid (from liquorice). At toothpaste quantities, spat out rather than swallowed, this is not a systemic exposure — but it is worth knowing it is there if you have been told to avoid liquorice.
- Stop using it and consult a dentist or doctor if you get mouth irritation, ulceration or a rash.
- This is a toothpaste, not a treatment. It does not treat gum disease, periodontitis or any infection. Bleeding gums, persistent bad breath, pain or a receding gum line are reasons to see a dentist, not reasons to change toothpaste.
- For external use in the mouth. Do not swallow. Keep out of reach of children.

FAQ
What is the difference between Double Mint and Sweet Herb Mint?
The flavour, and only the flavour. Both are Citeeth White Premium, both are 70 g, both carry the same three stain agents, the same double fluoride and the same CPC and glycyrrhizic acid. Double Mint is peppermint with spearmint — cold, sharp, the taste most people associate with a clean mouth. Sweet Herb Mint is softer and more herbal, and it is the one to pick if strong mint makes your mouth feel raw or if you dislike that particular cold burn. Until today our two product pages carried identical descriptions and said nothing about this, which made the choice between them impossible.
Will it actually whiten my teeth?
It will remove the stain film on them, which on a coffee, tea, wine or tobacco drinker is usually a visible change over four to six weeks. It will not lighten the natural colour of the tooth. Japanese whitening pastes — ホワイトニング — contain no peroxide and work entirely on what has settled on the outside of the enamel; the colour underneath comes from dentine and nothing you rinse out after two minutes reaches it. If your teeth are already clean and you want them a shade lighter, you want a dentist's bleaching treatment, and we would rather tell you that now than sell you a tube on a promise it cannot keep.
Can this be my only toothpaste?
Yes, and that is worth stating because it is not true of every product in this category. Citeeth White Premium contains two fluorides — sodium fluoride and sodium monofluorophosphate — so it protects against decay as well as lifting stain. Some Japanese stain pastes contain no fluoride at all, and using one of those as your everyday paste quietly removes fluoride from your routine. This is not one of those. Use it twice a day, spit rather than rinse, and it does both jobs.
Is it safe for enamel? The old page said it does not damage it.
We removed that sentence, because it was an absolute claim and Daiichi-Sankyo publishes no RDA figure that would let anyone verify it. What is worth knowing instead: this formula does most of its stain work chemically rather than by abrasion — polyphosphate loosens, PEG-8 dissolves, PVP keeps the pigment suspended — which is a gentler route than scrubbing. Use a soft brush, light pressure, twice a day rather than the "several times" the old page suggested, and do not brush within half an hour of anything acidic. That last habit protects enamel more than any paste choice does.
Will I pay customs duty or import VAT?
That depends on your country and on the declared value of the parcel, not on us. We ship from Japan with a correct customs declaration and full tracking; any duty or import VAT your country charges is collected by your local carrier or customs office on delivery. Check your national de-minimis threshold before ordering if you want to avoid a surprise.
