Cocoshine answers a different question from the one our product answers. Cocoshine is a toothpaste, the thing you brush with twice a day. Minvelle is a chewing gum for between brushings, one piece a day, chewed for at least 20 minutes, with 5.7 mg of nano-hydroxyapatite per 1.9 g piece printed on the box. It is an extra step, not a replacement for any toothpaste, Cocoshine included.

Cocofloss, COCOLAB, Cocoshine: one company, three names

Most people who search for "Cocofloss toothpaste" have met the floss first. Cocofloss is the original product: a textured dental floss that gave the company its name. The toothpaste came later, and it is not called Cocofloss. It is called Cocoshine. A third name sits on top of both. The company now trades as COCOLAB, and a bundle on its own store, the "COCOLAB SmileCare System", names the three product lines together: "Cocofloss, Cocoshine, and Cocobrush". So the floss, the toothpaste and the toothbrush are three lines under one house.

The legal name behind all three is Cocofloss, Inc. The brand's Terms & Conditions, checked on 26 September 2026, open with: "This page contains the terms & conditions ('Terms') from COCOFLOSS Inc. ('COCOLAB', 'we' or 'our')". The privacy notice says the same in nearly the same words, naming "Cocofloss, Inc. ('COCOLAB', 'we', 'us' and/or 'our')". Both documents list two websites: cocolab.com and pro.cocolab.com, the second being a channel for dental professionals.

Why cocofloss.com lands on cocolab.com

If you type cocofloss.com into a browser today, you end up at cocolab.com. We checked the redirect on 26 September 2026: the server answers with a permanent 301 redirect, and the response carries Shopify's own header "x-redirect-reason: primary_domain_redirection". That header means the store's platform has cocolab.com set as the main address and treats cocofloss.com as a secondary name for the same shop. Both hostnames serve the same store, with the same shop ID in the page code.

The domain records fit that picture. According to the registry record (RDAP), cocofloss.com was registered on 12 December 2014. Cocolab.com is much older, registered on 2 December 2000, which suggests a generic domain the company acquired later. Both now share the same registrar, the same expiry date in 2031 and the same last-change date in December 2025. Nothing about this is unusual. Brands that grow past their first product often move to a broader name, and the redirect is set up the standard way.

For a shopper, the practical point is simple: a Cocofloss toothpaste, a Cocoshine toothpaste and a COCOLAB toothpaste are the same product family, sold from the same store. When you compare listings, you compare Cocoshine.

Part 2

How much nano-hydroxyapatite is in Cocoshine? 3% active, two carriers

This is the question the review exists to answer, and the brand gives a clear headline figure: 3% active nano-hydroxyapatite. It repeats that number on every Cocoshine listing we checked. Its dedicated hydroxyapatite page says: "Cocoshine uses 3% of the highest-quality nano-hydroxyapatite, suspended in a silky-smooth formula designed for gentle, everyday brushing."

The same page names the raw material, which many brands do not: "We use nanoXIM® CarePaste by Fluidinova, the most trusted, high-performance nHA on the market. It's synthetic, vegan, and precision-engineered for purity, safety, and serious shine." Fluidinova is a Portuguese hydroxyapatite manufacturer, and CarePaste is its paste form of the ingredient. A paste raw material is hydroxyapatite suspended in a carrier, so the amount of raw material in the tube is larger than the amount of hydroxyapatite it delivers. That is why a brand can speak of two numbers: how much of the paste goes in, and how much active hydroxyapatite results.

The two listings, side by side

Here the brand's own pages part ways. Cocofloss sells the regular 4 oz Cocoshine tube under two live listings. They have the same ingredient panel, in the same order, with the same glosses; the same size; the same $15.00 price; and the same four flavours. Both say the tube delivers 3% active hydroxyapatite. They state different amounts of the raw material that produces it. Both quotes were captured from the product data on 26 September 2026:

Both quotes from the brand's live product data, checked 26 September 2026. The 15.5% wording also appears on the Jumbo, Travel, Duo, Trio and both Jumbo multipack listings.

We report both figures as the brand states them. We do not know which one describes the tube in your hand, and we have not tried to reconcile them: the two percentages could reflect different carrier concentrations, a formula change, or an older text left on one listing, and the pages do not say. What stays the same on both is the headline number, 3% active hydroxyapatite, and the formal ingredient list. If the carrier percentage matters to you, the brand's customer service line published in its refund policy (855.661.4719 or help@cocolab.com) is the place to ask.

What the ingredient panel says, and what it leaves out

The formal ingredient list on every Cocoshine product page we checked, adult and kids, names the ingredient plainly as "hydroxyapatite (mineral that strengthens, whitens, and reverses sensitivity)". It carries no percentage, no "(nano)" qualifier and no raw-material name. The word nano appears in the marketing copy around the panel, not in the panel itself. We note this as a difference between two parts of the same page and draw no conclusion about the particles in the tube.

The gloss in brackets is the brand's own wording. "Reverses sensitivity" is a strong claim, stronger than "reduces sensitivity", and it is the brand's claim, printed on its ingredient panel. We did not test it and we do not repeat it as fact.

Particle shape and size

Cocofloss describes the particles in two sentences on its hydroxyapatite page: "We use rod-shaped particles (not irregular ones), sourced from nanoXIM®", and "Nano particles (under 100nm) fit into the surface's microscopic grooves for a polished, smooth finish." "Under 100nm" is the only size figure the brand gives; there is no mean particle size or specification sheet on the pages we checked. That is still more than several brands we have reviewed, which say "nano" and nothing else.

The safety wording, and the EU rules

The brand's hydroxyapatite FAQ answers the safety question like this: "Our formula features nanoXIM®, the only nano-hydroxyapatite certified as safe for oral care by the European Scientific Committee on Consumer Safety." That is Cocofloss's wording, not ours, and it uses a word we would not. The Scientific Committee on Consumer Safety (SCCS) is an advisory scientific committee of the European Commission. It does not certify products or ingredients. It writes opinions, and the law comes afterwards.

Here is how the EU position stands on 26 September 2026. Hydroxyapatite (nano) was assessed as safe by the SCCS in opinion SCCS/1648/22, and it is permitted by Regulation (EU) 2024/858, in force since 4 April 2024, at up to 10% in toothpaste and 0.465% in mouthwash, for rod-shaped, uncoated particles. A later opinion, SCCS/1677/25, adopted on 26 June 2025, assessed higher levels as safe for a different particle specification; that is an opinion, not law. Cocoshine's stated 3% active sits inside the 10% toothpaste limit, and the brand's "rod-shaped" description matches the particle shape the regulation names. Cocoshine is sold from a US store, where the EU rule does not apply, but it is a useful yardstick. Our longer article on whether nano-hydroxyapatite is safe covers the safety research in detail.

If you are choosing between hydroxyapatite toothpastes mainly on the stated amount, 3% is on the lower side of what brands in this category print, and our ranking of hydroxyapatite toothpastes sorts the field by exactly what each brand publishes. A lower percentage is not a verdict on the paste. The research on hydroxyapatite toothpaste covers a range of concentrations, and few brands tell you both the raw-material and the active figure.

Part 3

The full ingredient list, in plain English

Cocofloss publishes the complete ingredient list on every Cocoshine product page, and it pairs each ingredient with a short gloss in its own words. That makes the panel easy to read. Here it is for the regular 4 oz tube in Delightful Mint, Lychee Breeze and Piña Colada, as captured on 26 September 2026:

water (you know, H₂O) · glycerin (natural hydrator) · silica (naturally-derived mineral that gently polishes) · xylitol* (plant-based sweetener that's microbiome-friendly) · hydroxyapatite (mineral that strengthens, whitens, and reverses sensitivity) · cellulose gum (plant-based thickener) · cocos nucifera (coconut) oil · natural flavor (spearmint oil, cornmint oil, anise, camphor, and menthol for breath freshening) · aloe barbadensis leaf juice* (naturally soothing) · sodium bicarbonate (baking soda, a natural surface stain remover) · sodium citrate (salt derivative that reduces sensitivity) · potassium chloride (natural mineral salt that reduces sensitivity) · stevia rebaudiana extract (natural sugar-free sweetener) · sodium lauroyl sarcosinate (naturally-derived cleanser). *Certified Organic (xylitol, aloe barbadensis leaf juice).

Read in plain English: water and glycerin form the base; silica is the polishing agent; xylitol and stevia sweeten it; hydroxyapatite is fifth on the list; cellulose gum thickens it; coconut oil and aloe juice are there for texture and feel; baking soda is a mild secondary cleaner; sodium lauroyl sarcosinate is the foaming agent. We compared the second 4 oz listing, the one with the 19.35% wording, line by line on the same day, and its panel is identical: same ingredients, same order, same glosses.

No sulfates, no peroxide, no fluoride

Every Cocoshine listing carries a "Made Without" line: "Fluoride, sulfates, parabens, peroxide, dyes, and artificial sweeteners", with some listings adding triclosan and propylene glycol. We checked that claim against the panel above. It holds: there is no fluoride, no peroxide and no sodium lauryl sulfate. The cleanser is sodium lauroyl sarcosinate, a different surfactant. Where a brand's marketing line and its ingredient list agree, that is worth saying, because it is not always the case in this category.

Three ingredients with a sensitivity gloss

The panel attributes a sensitivity effect to three ingredients at once: hydroxyapatite ("reverses sensitivity"), sodium citrate ("reduces sensitivity") and potassium chloride ("reduces sensitivity"). Potassium chloride and sodium citrate are a different route from potassium nitrate, which many toothpastes for sensitive teeth use; our Twice toothpaste review covers a potassium nitrate formula for comparison. The brand does not say how much each of the three contributes, and it does not cite a study for any of them. These are Cocofloss's claims. If sensitivity is your main reason for switching toothpaste, the person to ask is your dentist, because sensitivity has several causes.

Abrasivity: RDA 37, stated consistently

RDA, relative dentin abrasivity, is a lab score for how abrasive a toothpaste is. Cocofloss states it: "Low-abrasion polish (RDA 37) that creates a smoother, more reflective shine" on the adult tube, and "An ultra-gentle kid-friendly formula (RDA 37) that protects delicate young enamel while it cleans" on the kids tube. The figure is the same everywhere it appears. It is the brand's own figure; no lab certificate for it is published. By comparison, our BioMin review found two different RDA figures for the same tube on that brand's own pages. A consistent, low stated RDA is a point in Cocoshine's favour, particularly for a toothpaste sold on whitening.

Part 4

Does Cocoshine whiten teeth? What the evidence is

Cocoshine is sold as a whitening toothpaste, and every listing puts "Whitening" in the product name. So it is fair to ask what the whitening claim rests on. The answer, from the brand's own pages, is two lab footnotes and a described mechanism.

The mechanism, in the brand's words

The listings explain it this way: "Cocoshine helps fill in mineral gaps in the teeth, remove stains, and smooth the surface. Light is then better able to reflect off the teeth for a brighter, whiter smile." A bullet on the same pages splits the work between two ingredients: "Dual-Action Whitening: While gentle silica lifts existing stains, nHA smooths the tooth surface to help stop new ones from taking hold."

That is a clear and fairly modest description. By the brand's own account, the stain removal is done by silica, the polishing agent, and hydroxyapatite's role is to smooth the surface so it reflects light better. There is no peroxide in any Cocoshine tube, so there is no bleaching. This is surface whitening, the same broad category as other low-abrasion whitening toothpastes, and it works on surface stains rather than on the colour inside the tooth.

The single-tooth test

The whitening claim carries this footnote, repeated on nearly every Cocoshine listing we checked on 26 September 2026:

"After 1 week's worth of brushing for a single tooth, the Delicious Mint toothpaste formulation whitened by a maximum of 1.96 VITA® tooth shades (Intertek, 2023)."

Three details in that sentence matter. First, by its own wording the test was on "a single tooth", which reads as a lab test on one tooth rather than a study of people brushing. Second, "1 week's worth of brushing" describes simulated brushing time, not a week of daily use by a person. Third, "a maximum of 1.96 VITA tooth shades" is a best-case figure, not an average across teeth or people. VITA is a standard shade guide dentists use to describe tooth colour. Intertek is a large, well-known testing company, and the test was commissioned by the brand. No sample size, method or full report is published on the pages we checked, and the test is not a journal article.

A second footnote reads "Clinically tested by HelloBiome, 2024". HelloBiome is a microbiome testing service, and the footnote sits next to the brand's claim that Cocoshine respects the oral microbiome. The brand gives no method, sample size or result for it on the pages we checked.

We also searched PubMed, the US National Library of Medicine's database of biomedical research, for "Cocoshine" and "Cocofloss" on 26 September 2026. Both searches returned zero records. There is no peer-reviewed study of Cocoshine, or of any Cocofloss product, in PubMed. That does not mean the paste does not whiten. It means the published evidence is one brand-commissioned test on one tooth, and readers should weigh it as that.

What the wider research says about hydroxyapatite and tooth colour

Independent of Cocoshine, researchers have looked at whether hydroxyapatite toothpaste whitens teeth. A 2023 systematic review by Limeback, Meyer and Enax in Dentistry Journal (PMID 36826195) included 17 studies, most of them laboratory studies, and concluded that "the regular use of hydroxyapatite-containing oral care products effectively whitens teeth, but more clinical trials are required to support the preliminary in vivo evidence." Two of the three authors are employees of Dr. Kurt Wolff GmbH & Co. KG, a German toothpaste manufacturer with no tie to Cocofloss, and the paper declares it.

A 2021 review by Chen and colleagues in Materials (PMID 34500955), from university authors who declared no conflict of interest, lists tooth whitening as one of the main uses of hydroxyapatite in oral care, alongside remineralisation and reduced sensitivity, and adds that "clinical data on these products is limited with varied results." Neither review tested Cocoshine, a 3% active formula or nanoXIM specifically. They describe hydroxyapatite as an ingredient category.

We cover that question in its own article. Read does hydroxyapatite whiten teeth for the full evidence on hydroxyapatite and tooth colour.

If whitening is your main goal, it also helps to know which stains a toothpaste can reach. Our guide on how to whiten teeth without damaging enamel explains the difference between surface stains and colour inside the tooth, and why a low RDA matters when you brush every day.

Part 5

Who makes Cocofloss? The founders and the records

Cocofloss is a founder-led brand with named people behind it, which is more than many oral-care storefronts offer. The brand's Our Story page, checked on 26 September 2026, opens: "We are the Cu sisters. Chrystle, the dentist, is an extreme, pro-flosser. Cat, the dreamer, is a little lazier when it comes to flossing." The About page describes the pair as "a dentist and an artist" and says "Dr. Cu has perfected new oral care solutions". An image on the site's own menu carries the caption "Dr. Chrystle and Cat Cu holding Cocolab products".

The brand calls Chrystle Cu "the dentist" and "Dr. Cu". It does not publish a dental school, degree or licence number on the pages we checked, so we report that description as the brand's own. We did not look her up in a state dental board registry for this review.

One more name on the site is easy to mix up. Cocofloss publishes an author page for Dr. Joyce Kahng, described on that page as a cosmetic and restorative dentist who owns a dental studio in Orange County, California, and who attended the University of the Pacific Arthur A. Dugoni School of Dentistry. Her page sits in the site's authors section with other named contributors. Nothing on it says she co-founded Cocofloss or formulated Cocoshine, so we treat her as a content contributor, not as part of the company.

The kids listing adds its own line: "Formulated by a dentist with her own kids in mind". The listing does not name the dentist, so we quote it as the listing's claim.

Company records

The legal entity is Cocofloss, Inc., named in both the Terms & Conditions and the privacy notice. The brand does not publish a state of incorporation, a registration number or a registered address on any page we checked. We tried the California Secretary of State's business search and OpenCorporates on 26 September 2026; both blocked automated access, so we could not confirm the registration details and we state none. The federal court record in Part 6 names Cocofloss Inc. as a defendant and shows a lawyer appearing on its behalf, which independently confirms that the company exists.

Customer service, per the brand's refund policy: 855.661.4719 or help@cocolab.com, 9 a.m. to 6 p.m. Eastern time, Monday to Friday.

Part 6

Is there a Cocofloss lawsuit? One case, not about the toothpaste

"Cocofloss lawsuit" is a real search, so here is the direct answer. On 26 September 2026 we searched CourtListener, the public archive of US federal court records, for "Cocofloss", "Cocolab" and "Cocoshine". "Cocolab" and "Cocoshine" returned no results. "Cocofloss" returned four, and one of them concerns this company. The other three were unrelated cases that matched the keyword.

CourtListener federal docket, checked 26 September 2026. No settlement terms appear on the public docket.

What kind of case was it? The cause and nature-of-suit codes place it under the Americans with Disabilities Act. Cases filed under these codes against online shops usually allege that a website is not accessible to people with disabilities, for example to blind users who rely on screen readers. It was not a product-safety case, a false-advertising case or a claim about what is in the toothpaste. The complaint's allegations were never tested in court: the plaintiff dismissed the case herself about three months after filing it.

The public docket shows no settlement terms, and we do not state or suggest any. The record shows only this: the case was filed, the company's lawyer appeared, the plaintiff filed a notice of voluntary dismissal, and the court closed the case.

FDA records and recalls

We searched DailyMed, the US National Library of Medicine's database of drug labels, for Cocofloss, Cocoshine and Cocolab on 26 September 2026. All three returned no labels. That is expected: Cocoshine contains no fluoride and makes no anticavity drug claim, so it is sold as a cosmetic toothpaste and does not need a drug label. The openFDA enforcement database returned no recall or enforcement record under any of the three names on the same day.

The brand does not claim the ADA Seal of Acceptance anywhere we checked. That is also expected. The American Dental Association's anticavity Seal requires fluoride, which Cocoshine does not contain.

Part 7

Price, subscription and returns: the fine print

On 26 September 2026 a 4 oz (113 g) Cocoshine tube cost $15.00 on the brand's store. The 7 oz Jumbo cost $25.00, the 1 oz Travel tube $7.00, a Duo of 4 oz tubes $28.00 and a Trio $45.00. Jumbo multipacks were $46.00 for two and $65.00 for three. Per ounce, the Jumbo is the cheapest way to buy it, at about $3.57 an ounce against $3.75 for the 4 oz tube.

Subscription

On the product page we checked, the subscription option is selected by default. It takes 10% off: $15.00 one-time becomes $13.50, with delivery every 2, 4 or 6 months. If you only want to try one tube, switch the selector to one-time purchase before you check out. The page code also contains an old pop-up for a "Semi-Annual Sale" that, by its own text, ended on 8 July 2026. We treat it as leftover markup, not a current offer. It does confirm 10% as the brand's standard subscription rate.

Shipping and where it is sold

The site banner read "FREE shipping on orders +$30" when we checked. We did not find the full shipping policy, so we cannot tell you which countries the store ships to. Besides its own store, Cocofloss confirms on its own site that it sells on Amazon; we do not link marketplace listings. It also runs a separate store for dental professionals at pro.cocolab.com. The Meta Ad Library showed about 155 active ads matching "Cocofloss" on 26 September 2026, almost all from the brand's "Cocolab" page, including a 15% first-order code offer.

Returns

The refund policy, checked on 26 September 2026, reads in part: "If the Products delivered to you do not match this warranty, our sole obligation and your sole remedy is an exchange or refund within 30 days of your purchase. Please note that the Product must be returned unused, in original packaging including all tags. In case of refund neither the original shipping cost nor the return shipping cost will be repaid." Purchases made through third parties such as Amazon go back through that platform.

In practice this means an opened tube cannot be returned. If you try Cocoshine and do not like it, you keep it. Starting with the $7.00 Travel tube is the cheapest way to test the taste and texture. In the brand's favour: we searched the home page, About page, FAQ, hydroxyapatite page and every toothpaste listing for "guarantee", "risk-free", "money-back" and "100% satisfaction" and found none. The site does not promise more than the policy gives.

Reviews

The Trustpilot profile for cocofloss.com showed a TrustScore of 3.8 from 2 reviews on 26 September 2026, both five stars. One is about the toothpaste, the other about the floss. Two reviews tell you almost nothing either way. The Better Business Bureau had no business profile for Cocofloss or Cocolab, so there is no BBB rating to report. We did not base this review on forum threads or social posts; if you read them, weigh single experiences as single experiences.

Part 8

Kids Cocoshine: what the label says

Cocofloss sells a kids listing, "Kids-Favorite Flavors", in Wild Strawberry and Piña Colada, 4 oz, $15.00. It uses the same hydroxyapatite ingredient line as the adult paste, is fluoride-free, and states "RDA 37". The listing describes it as "Formulated by a dentist with her own kids in mind, Cocoshine delivers serious dental care made for little routines". The kids panel we captured lists water, glycerin, silica, xylitol, hydroxyapatite, flavor, cellulose gum, coconut oil, potassium chloride, aloe leaf juice, sodium bicarbonate and sodium citrate, with no fluoride, no peroxide and no sodium lauryl sulfate.

We searched the kids product page on 26 September 2026 for an age range, a pea-size amount, a supervision note, a swallowing warning or a line about asking a dentist. We found none of them. A fluoride-free cosmetic toothpaste is not required under US rules to carry the Drug Facts warnings that a fluoride toothpaste carries, so this is not a compliance question. It does mean the page leaves those decisions to the parent.

If you are choosing a toothpaste for a young child, the questions that matter are the child's age, how much paste to use, whether the child still swallows toothpaste, and whether your dentist recommends fluoride for your child's cavity risk. Our guide to oral care for children under 6 walks through those questions. Ask your child's dentist before you switch.

Part 9

Cocoshine and a nano-hydroxyapatite gum: different tools

You may be here because you are weighing a hydroxyapatite toothpaste against a fluoride one. We sell a nano-hydroxyapatite product, so here is our position plainly. Fluoride is not the enemy. A fluoride toothpaste brushed twice a day is what most dentists recommend as the base of home care, and it has decades of cavity-prevention research behind it. Hydroxyapatite toothpaste is a real alternative for people who choose it with their dentist; our comparison of nano-hydroxyapatite and fluoride sets out the evidence for each. Cocoshine is one fluoride-free option; our ranking of fluoride-free toothpastes covers the wider field.

A nano-hydroxyapatite gum does a different job at a different time. You brush in the morning and at night. Between those two moments you eat and drink, and the mouth goes through acid swings. A sugar-free gum chewed after a meal increases saliva flow, and ours adds a measured amount of nano-hydroxyapatite during that time. That is an extra step, not a substitute for Cocoshine or any other paste.

What a gum cannot do

• It does not replace brushing. A gum does not remove plaque the way a toothbrush and paste do.
• It does not replace fluoride toothpaste. If your dentist has recommended fluoride, keep using it.
• It does not repair a cavity. No gum and no toothpaste fills a hole in a tooth. That is a job for a dentist.
• It contains no peroxide and does not bleach teeth. Minvelle contains no peroxide and does not bleach teeth. If whitening is your main goal, a gum is not the tool; our comparison of whitening strips and remineralizing gum explains why.
• It has not been in a clinical trial. There is no clinical trial on the finished Minvelle gum. What we publish is the dose, the full ingredient list and a batch certificate from lab testing of the finished gum.

Minvelle prints the dose on the box: 5.7 mg nano-hydroxyapatite per piece. See the gum.

In fairness

What Cocofloss does well

A review built on documents owes the brand the documents in its favour, and Cocofloss has several. The first is openness about ingredients. Every Cocoshine product page shows the full ingredient list, with a plain-English note next to each item, on the page itself rather than in a PDF or behind a login. We checked the "Made Without" line against that list and it holds.

The second is traceability. Cocofloss names its raw material and supplier, nanoXIM CarePaste by Fluidinova, and describes the particle shape and an upper size limit. Many brands in this category say "nano-hydroxyapatite" and stop there. Naming a supplier gives a reader something to check.

The third is a consistent abrasivity figure. RDA 37 appears on the adult and kids listings alike, and it is low. For a toothpaste sold on whitening, a low stated abrasivity is a sensible design choice, and the brand's own description of how the whitening works, silica for stains and hydroxyapatite for surface smoothness, is modest rather than dramatic.

The fourth is a clean record on what we could check. No FDA recall or enforcement record under any of its three names, and one federal case in the public record, an ADA accessibility claim that the plaintiff dismissed within three months and that did not concern the product. The company has named founders with a specific story, not an anonymous storefront. And its return policy, while strict, is the only return language on the site: there is no guarantee promise on top of it.

The points a reader should still know, the two carrier percentages on two listings of the same tube, a panel that does not say nano, a whitening claim resting on one brand-commissioned test on a single tooth, no percentage-by-weight beyond the 3% figure, no age guidance on the kids page, and returns only for unused tubes, do not cancel any of that. They are the record, reported alongside it.

The verdict

Cocofloss toothpaste, in one paragraph

Cocofloss toothpaste is Cocoshine, sold by Cocofloss, Inc. under the COCOLAB name and founded by the Cu sisters, one of whom the brand describes as a dentist. Every tube is fluoride-free and peroxide-free and states 3% active nano-hydroxyapatite from nanoXIM CarePaste by Fluidinova, rod-shaped and under 100 nm by the brand's description, with a stated RDA of 37. Two live listings of the same 4 oz tube give different carrier percentages for that 3%: 15.5% and 19.35%. The whitening claim rests on one Intertek lab test on a single tooth from 2023, and there is no PubMed record for the product. A 4 oz tube is $15.00, or $13.50 on subscription, and opened tubes cannot be returned. The one federal case we found, Bunting v. Cocofloss Inc., was an ADA website-accessibility claim that the plaintiff voluntarily dismissed in April 2022.

Who it suits: buyers who want a fluoride-free, low-abrasion hydroxyapatite toothpaste with a named supplier and a readable ingredient panel, and who like the flavour range. Who should look elsewhere: readers who want a clinical study of the finished paste, a higher stated hydroxyapatite percentage, or a toothpaste with fluoride.

Where Minvelle fits, briefly. A gum does not replace a toothpaste. Minvelle is an add-on for between brushings: one piece a day, chewed for at least 20 minutes, with 5.7 mg of nano-hydroxyapatite per piece printed on the box and a published batch certificate. It contains no peroxide, does not bleach teeth, and there is no clinical trial on the gum itself.

Questions, answered

The things people actually ask
