If you are here because you want fluoride-free enamel care, you are also the reader our gum is for, as an add-on rather than a swap. Minvelle prints what this review had to go looking for: 5.7 mg of nano-hydroxyapatite per 1.9 g piece, 18 pieces per box, one piece a day, chewed for at least 20 minutes between brushings. Keep your paste. The gum covers the hours after lunch and coffee when a sink is not around.

Boka compared: what is published, what stays open

Swipe sideways on mobile. All rows reflect the listed pages and records as checked on 25 September 2026; pages change, so use the sources to re-check anything before relying on it.

Part 1

What Boka actually sells

Boka sells a range, not a single tube. On its own store the catalogue ran to 56 listings when we checked, including bundles and multi-packs. The core is a family of fluoride-free toothpastes built on nano-hydroxyapatite, abbreviated n-Ha or nHA on Boka's pages. The flagship is Ela Mint. Around it sit more adult flavors: Cinna Mint, Coco Ginger, Lemon Lavender, Cherry Blossom (sold as mint-free) and Bold Mint.

Then come the specialty lines. The whitening line includes Refresh Mint Whitening, Charcoal Yuzu Mint Whitening and a Whitening 3-Pack, and there is a BrightBoost whitening powder that Boka describes as peroxide-free. The Sensitive paste, sold as Mint Coconut Cream, adds 5% potassium nitrate, which makes it a different regulatory animal, covered in Part 7. A probiotic line, Citrus Mint Probiotic and Peppermint Blossom Probiotic, contains Lactobacillus paracasei according to Boka's launch press release. The kids' range covers Bubble Gum, Blueberry Dragon Fruit, Strawberry Mango, Watermelon Mint and Orange Cream. Floss, mouthwash tablets and travel sizes round it out.

This review focuses on the adult nano-hydroxyapatite pastes, with Ela Mint as the reference product, because that is what most people mean when they search for a Boka toothpaste review. Where the Sensitive or whitening lines differ in a way that matters, we say so. Our wider fluoride-free toothpaste ranking puts Boka next to seven other pastes if you want the category view first.

One thing to keep in mind from the start: the flavors differ, and flavor systems differ in essential oils, which matters to people who react to mint, anise or cinnamon. Boka sells Cherry Blossom as mint-free for exactly that reason. The nano-hydroxyapatite question, how much of it is in the tube, applies to all of them equally, because Boka does not publish the figure for any of them.

Part 2

Who makes Boka: the paper trail

Start with the trademark, because it is the cleanest record. The USPTO register shows the word mark BOKA, serial number 86534719, registration 4965811. It was filed on February 13, 2015, lists a first use in commerce of August 19, 2015, and was registered on May 24, 2016. It is live, and a renewal was recorded on July 16, 2026. The owner is Boka, LLC, which the register describes as a Minnesota limited liability company. The goods on record today are toothpastes, toothbrushes and dental floss, plus online retail services for dental hygiene products. Mouthwash and whitening kits were once in the toothpaste class and were later deleted from it.

Theodent points to an FDA clearance in its marketing, and our Theodent toothpaste review checks that claim and its study numbers the same way.

A Boka and Essor press release gives 2015 as the founding year, which lines up with the USPTO first-use date. One trade-press profile says 2016. We go with 2015 because a federal register backs it.

Addresses differ across records. Boka's refund policy names the return address as Boka, LLC, 2801 Galvin Dr #200, Elgin, Illinois. The Better Business Bureau lists Boka, LLC in Chicago. A DentistryIQ interview with the co-founder gave Minneapolis as headquarters, consistent with the Minnesota organization on the trademark.

Essor Group, the company above the brand

Boka today is part of Essor Group, Inc., a Chicago consumer-goods company that trade press describes as a brand-building platform. Trade press reported that Essor was formed in September 2024 by the merger of two companies, Branded and Heyday, in a deal reported at around $400 million. Those deal details come from trade press, not from a filing we could read. The primary-source link between Essor and Boka is firmer: both 2025 BBB National Programs advertising decisions, and a federal court docket, name Essor Group, Inc. as the company behind Boka products.

There is also a third name. The FDA's drug directory lists the labeler for the Boka Sensitive paste as Karaka LLC, 444 W Lake St, Suite 1700, Chicago. That is a different legal name from Boka, LLC, in the same city as the BBB listing. Large consumer-goods groups often split brands and product registrations across several legal entities, and nothing in the records suggests anything beyond that. It is simply useful to know if you ever need to find the company behind a specific tube.

The founder, and a claim you may read elsewhere

Boka's own About Us and advisory pages do not name a founder. Trade press does: a DentistryIQ interview identifies James Hagen as co-founder and CEO. Per that interview, Hagen "started his career as a hedge-fund analyst in NYC before becoming the president of American Dental Accessories," and holds a bachelor's degree from the University of Michigan and an MBA from Columbia. He is not described as a dentist in any source we found. If you have read that Boka was founded by a dentist, we could not find evidence for it, and Boka's own pages make no such claim.

What Boka does publish is an Oral Health Advisory Committee: Diane Cummins, described as an oral health researcher and industry consultant; Dr. Foti Panagakos, described as a founding dean of a school of dental medicine; Raj Kohli, PhD, described as a former executive vice president for global R&D and technology strategy; Alan Wolpert, described as a consumer brands and oral care leader; and Dr. Victoria Sampson, described as a functional dentist and oral microbiome researcher. We list the names as Boka presents them and did not verify licenses or credentials.

Part 3

Ela Mint ingredients, line by line

Here is the full Ela Mint ingredient list as printed on the product page, in order: Water (Aqua/Eau), Glycerin, Hydrated Silica, Sorbitol, Silica, Hydroxyapatite*, Sodium Benzoate, Sodium Lauroyl Sarcosinate, Mentha Piperita (Peppermint) Oil, Mentha Viridis (Spearmint) Leaf Oil, Illicium Verum (Anise) Fruit/Seed Oil, Gaultheria Procumbens (Wintergreen) Leaf Oil, Xylitol, Xanthan Gum, Stevia Rebaudiana Leaf/Stem Extract, Dimethyl Sulfone, Aloe Barbadensis Leaf Juice, Sodium Bicarbonate, Camellia Sinensis Leaf Extract, Cucumis Sativus (Cucumber) Fruit Extract, Persea Gratissima (Avocado) Fruit Extract, Mangifera Indica (Mango) Fruit Extract, Menthol, Elettaria Cardamomum Seed Oil, Potassium Chloride, Limonene. The asterisk is footnoted "Nano".

Taken on its own terms, this is a conventional modern paste with a natural-leaning extras list. The skeleton is water, humectants and silica abrasives, the same as in most mainstream toothpastes. What sets it apart is what is missing: no fluoride, no sodium lauryl sulfate, no parabens. What it adds is nano-hydroxyapatite and a long tail of botanicals.

Swipe sideways on mobile. Ingredient list as printed on the Ela Mint product page, checked 25 September 2026. Function notes are general descriptions of each ingredient's usual role, not claims made by Boka.

Two things to take from the list. First, hydroxyapatite in sixth place tells you it is a real ingredient and not a trace addition. But ingredient order only gives a rough hint of amounts, and it cannot be turned into a percentage. That is why the next part matters. Second, silica is doing the cleaning, and Boka publishes no RDA (relative dentin abrasivity) figure for any paste we checked. If abrasivity matters to you, for example because you have exposed root surfaces, our RDA explainer covers what the number means and why so few brands print it.

On the product page, Boka describes the active like this: "Our proprietary and innovative formula includes Nano-hydroxyapatite (n-Ha), a biomimetic mineral form of the same material that naturally makes up 97% of your teeth material and 70% of your dentin." Read that sentence carefully, because it gets misquoted. The 97% and 70% figures describe natural enamel and dentin. They are not the amount of nano-hydroxyapatite in the tube, and Boka does not say they are.

Part 4

The missing number: dose versus particle size

Every nano-hydroxyapatite paste raises the same two questions: how much of it is in there, and how small are the particles. Boka answers one of them in unusual detail and declines the other in so many words.

What Boka says about the percentage

Boka's help center has an article titled "What is the percentage of Nano-Hydroxyapatite?". Its answer, verbatim: "Boka works with a high-quality lab in Western Europe. Our Boka toothpaste has a safe level of nHA and we've partnered with formulators to come up with the perfect concentration to ensure safety while delivering the maximum benefits of tooth remineralization, enamel protection, and anti-sensitivity. For proprietary purposes, we're unable to share the exact % of nHA in our products."

The same article continues: "While the % of n-Ha in our toothpaste is proprietary, we can share that our toothpaste is proven to support enamel health, helping to fill small holes and depressions on the enamel's surface." That is Boka's wording. How the "remineralization" part of that language fared before advertising regulators is Part 6.

So this is not a gap by silence. Boka was asked, published the question in its own help center, and answered that the figure is proprietary. That is a legitimate business choice, and plenty of brands in this category make it. It does mean a buyer cannot compare Boka against pastes that do print a percentage, and it means researchers cannot either, as the next part shows.

What Boka says about particle size

A second help-center article, "What is the shape of the Nano-Hydroxyapatite?", goes the other way. Verbatim: "Our n-Ha nanoparticles are nanorods having lengths of 20-80 nm (typically 50-60 nm) and widths of 10-15 nm. This is significantly much smaller than the dentine tubules that typically have 1-2 microns diameter (so, considering an averaged size of 50 nm) we have particles about 40x smaller than the dentine tubules."

It also compares itself with micro-sized hydroxyapatite, which some other brands use: "...the smaller mean particle size of micro-HA you find in the market has at least 5 or 10 microns, which are 5 to 10 times larger than the dentine tubules and will not occlude effectively..." That comparison is Boka's own argument, and we pass it on as such. If you want the neutral version of the nano versus micro debate, our nano vs non-nano explainer walks through it.

Particle size is a real disclosure, and more than most brands give. Boka deserves credit for it. It is just the less useful half of the pair for a shopper, because two pastes with identical particles can contain very different amounts of them.

The contrast inside Boka's own range

The Sensitive paste makes the gap easy to see. Its product description states that it is "formulated with 5% potassium nitrate to help reduce sensitivity caused by cold, heat, acids, sweets, or contact." The FDA-listed Drug Facts panel agrees: "Potassium Nitrate 5%" as the active ingredient. The same panel lists "Hydroxyapatite (nano)" among the inactive ingredients, with no percentage. A Drug Facts panel states the strength of the drug active, while cosmetic ingredients carry no percentages, so this follows the labeling format. The practical result is that in the same tube, one active has a number and the other does not.

If you want to know why the dose question matters so much in this category, our piece on how many milligrams of hydroxyapatite are actually in a product explains it with the numbers other brands do print. Twice, for example, prints 5 percent nano-hydroxyapatite on its Happy Mint tube, as our Twice toothpaste review shows.

Part 5

What the one Boka study actually tested

We searched PubMed for studies naming Boka. Exactly one paper tests an actual Boka product. Two other hits contain "Boka" only as an unrelated word in Greek pediatric-dentistry studies, and we set them aside.

The paper is Amaechi and colleagues, "In vitro evaluation of the ability of nanohydroxyapatite toothpastes to enhance remineralization of enamel caries lesion," Journal of Dentistry, 2025. Here is what it did, as recorded in PubMed. The researchers used bovine enamel blocks, 160 in total, 20 per product across 8 products. They created early caries-like lesions, then ran 14 days of pH cycling with toothpaste treatments three times a day. The main outcome was the percentage change in surface microhardness, a laboratory stand-in for remineralization.

The eight products were: Crest Cavity Protection (1100 ppm fluoride), ClinPro 5000 (5000 ppm fluoride), Fygg (20% nanoXIM as the study labels it; Fygg's own FAQ gives 3.1% final nano-hydroxyapatite), Boka (listed as "nanoXIM; concentration not disclosed"), Dr. Jen (10% nanoHAP), Risewell Regular (10% microHAP), Risewell PRO (5% nanoXIM plus microHAP) and Just-Ingredients Powder (15% microHAP). Notice that Boka is the only product in the table without a percentage. The authors could not fill in that cell either.

Swipe sideways on mobile. Figures as recorded in the PubMed entry for PMID 40744295, checked 25 September 2026.

Read it fairly in both directions. In favor of Boka: in this lab model it did produce measurable surface remineralization, and it was statistically in the same range as most of the other pastes, including the fluoride products. Against the strongest version of the marketing: it trailed the one high-percentage nano-hydroxyapatite paste in the panel by a clear, statistically significant margin.

And keep the limits in view. This was an in-vitro study on cow enamel, not a trial in human mouths. Lab remineralization of surface lesions tells you a paste can deliver mineral under controlled conditions; it does not tell you how many cavities it prevents in people. It was one study, not a series. No PubMed record we found reports a clinical trial of a finished Boka product, and Boka's pages do not cite one for the finished formula. The broader nano-hydroxyapatite literature is a separate question, covered in our roundup of hydroxyapatite toothpaste studies and our nano-hydroxyapatite vs fluoride comparison.

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

Part 6

The 2025 advertising decisions

This is the part of the record most Boka reviews leave out, and it is a primary source. BBB National Programs runs the US advertising industry's self-regulation system. Its National Advertising Division (NAD) reviews challenges to advertising claims, and its National Advertising Review Board (NARB) hears appeals. It is not a court and not the FDA. Companies take part voluntarily, and its decisions are recommendations.

The challenge came from The Procter & Gamble Company, the maker of Crest, a fluoride competitor. That context matters and a fair reader should keep it in mind: a rival brought the case. It does not change what the reviewers found, but it explains why the case exists.

NAD, case #7412

In its 2025 decision, NAD found that Essor Group had a reasonable basis for the claim that Boka toothpaste is made with nano-hydroxyapatite. That part of the challenge failed. NAD recommended that Essor discontinue claims that Boka toothpaste "remineralizes" or "fortifies" teeth or enamel, along with whitening claims and prebiotic claims for the mouthwash, citing insufficient evidence on the products themselves. Essor said it would appeal.

Wellnesse, another fluoride-free US brand, makes cavity claims of its own, and our Wellnesse toothpaste review quotes each one next to what the trials found.

NARB, July 2025

On appeal, NARB affirmed. Its decision found that Essor "lacked adequate substantiation" for the challenged claims. On remineralization, NARB wrote that "neither the Food & Drug Administration nor the American Dental Association has concluded that n-HA remineralizes teeth." On whitening, it said Essor "provided no evidence of any testing on its own formulated oral care products." On the breath and prebiotic mouthwash claim, it found "no testing on the product as formulated by Essor."

Essor's response, as reported in the decision: it would comply with the recommendations, while stating that its position is "underpinned by a comprehensive dossier of decades of peer-reviewed research." That dossier refers to research on nano-hydroxyapatite as a material. NARB's point was narrower: the question was testing of Essor's finished products, not of the ingredient in general.

What this does and does not mean

It does not mean nano-hydroxyapatite does nothing. NAD accepted that Boka contains it, and the ingredient has its own research base. It does not say anything about safety. What it means is that, as of 2025, the advertising reviewers did not find product-specific evidence behind Boka's remineralize, fortify and whitening claims, and Essor agreed to comply. We did not re-audit every page of Boka's live site against the decision, so we cannot tell you which lines have changed since. The help-center sentence quoted in Part 4 was still live when we checked. If a claim on a Boka page matters to your decision, compare it against the NARB wording in the sources.

One interesting overlap: the 2025 lab study in Part 5, published the same year, did measure remineralization with a Boka paste on enamel blocks. That is not the same as a clinical claim that a paste remineralizes teeth in people, and the regulators and the researchers were answering different questions. Both are real. We present them side by side.

Part 7

FDA, the ADA Seal, and the Sensitive paste

Boka's help center answers the regulatory question directly. Verbatim: "Boka toothpaste is not FDA or ADA-approved but has been tested and proven to be non-toxic and safe if swallowed. Our products are often recommended by dental professionals to their patients."

Some context makes this less alarming than it may sound. A toothpaste without a drug active, like Ela Mint, is sold as a cosmetic in the US, and the FDA does not approve cosmetics before sale. So "not FDA-approved" is true of most toothpastes that make no drug claim. The ADA Seal of Acceptance is voluntary, and Boka does not carry it by its own account. Our piece on why many dentists still default to fluoride covers why the Seal matters to some dentists and not to others.

The one Boka product that is an FDA-listed drug

Boka Sensitive is the exception. It is listed in the FDA's National Drug Code directory as an over-the-counter monograph drug, application number M022, NDC 87161-444, with a marketing start date of October 9, 2025. The labeler is Karaka LLC in Chicago. Its active ingredient is potassium nitrate at 5%, listed on the Drug Facts panel with the purpose "Antisensitivity". The brand says the paste helps "reduce sensitivity caused by cold, heat, acids, sweets, or contact". Nano-hydroxyapatite appears in that panel as an inactive ingredient.

For a buyer this means two things. The Sensitive paste has a declared, regulated active at a declared strength, and its label follows the drug-facts format. And its sensitivity claim rests on potassium nitrate, the same active many conventional sensitivity pastes use, rather than on the nano-hydroxyapatite. Boka Sensitive costs $13.98 a tube, about $2.36 more than Ela Mint.

Heavy metals, in Boka's words

Boka also has a help-center article on heavy metals. It says trace amounts "can be present at low levels that are not harmful to health," and that "Boka requires that our toothpaste not only meets FDA guidelines (as confirmed through third party testing), but also that all our raw materials are tested and verified to be within California Proposition 65 limits for heavy metals." Independent lab results about Boka pastes are discussed online. We did not verify the original reports, so we quote only Boka's own statement and do not repeat any numbers. For the general safety question around the ingredient itself, see is nano-hydroxyapatite safe.

We also looked for FDA warning letters and recalls naming Boka, Boka LLC, Essor Group or Karaka LLC and found none in our search. That is a "none found", not a certified absence.

Part 8

Boka vs Sensodyne: the facts side by side

"Boka vs Sensodyne" is a common search, and the honest answer starts with the fact that they are different kinds of product. Our Sensodyne label check went through all 26 US Sensodyne and Pronamel leaflets in August 2026. Every one is an OTC drug built on fluoride plus a desensitizing active: either stannous fluoride 0.454%, or potassium nitrate 5% plus sodium fluoride. None lists hydroxyapatite, active or inactive.

Swipe sideways on mobile. Boka facts checked 25 September 2026; Sensodyne facts from our August 2026 label check, linked above.

The practical split: if you want fluoride in your paste, Sensodyne has it and Boka does not. If you specifically want a fluoride-free paste with nano-hydroxyapatite, Boka is in that category and Sensodyne is not. If your reason for looking at either is tooth sensitivity, note that Boka Sensitive and Sensodyne's potassium-nitrate lines declare the same desensitizing active at the same strength; the difference is the fluoride on Sensodyne's side and the nano-hydroxyapatite on Boka's. Which of those suits your teeth is a question for your dentist, not for a product page. Our list of Sensodyne alternatives covers more options on both sides of the fluoride line.

Part 9

Price math, per tube and per month

Prices on boka.com when we checked, in US dollars:

Swipe sideways on mobile. Prices as displayed on boka.com, 25 September 2026. Retail prices at Target, CVS, Walmart and other stores may differ.

How long a tube lasts depends on how much you use and how many people share it, so we will not invent a number. The simple way to cost it: if one tube lasts you a month, Boka costs $11.62 a month at one-time prices, $9.88 on the subscription, or about $10.66 buying 3-packs. If it lasts six weeks, divide accordingly.

Shipping from boka.com is free on standard orders over $34.99 within the contiguous US, and over $74.99 to Hawaii, Alaska and Canada. Below that it is a flat $5.99 standard or $9.99 expedited. A single tube therefore costs $17.61 delivered, while a 3-pack at $31.99 still falls short of free shipping. That quirk is worth knowing before you check out.

For context against the rest of the category, Boka's shelf price sits in the middle of fluoride-free nano-hydroxyapatite pastes. You pay a premium over a mainstream fluoride paste, and you get a brand you can find in stores, which several smaller competitors cannot offer.

And since you may be weighing the gum too, here is ours in the same terms. Minvelle is €24.99 for a box of 18 pieces at one piece a day, which works out to about €1.39 per piece. It is a separate cost on top of your toothpaste, not a replacement for it, and it only makes sense if you want something for the between-brushings part of the day.

Part 10

Refunds, subscriptions and shipping

Boka's refund policy, verbatim: "If you decide that you'd like to return your Boka product, please contact us to initiate a return within 30 days of purchase. We offer a full product cost refund (less any incurred shipping costs) within 30 days of your purchase. To be eligible for a return, your item must be unused and in the same condition that you received it. It must also be in the original packaging." On exchanges: "We only replace items if they are defective or damaged."

The practical meaning is simple. If you open a tube, try it and dislike the taste or texture, the policy as written does not cover a refund. We found no satisfaction guarantee or "try it risk-free" wording anywhere on Boka's own site. If you see money-back guarantee language on a marketplace listing, it comes from that seller, not from Boka's policy, so check which seller you are actually buying from.

Our own guarantee is also for unopened boxes only, so this is not a criticism unique to Boka. It is simply a detail to know before you order several tubes at once.

Subscriptions

Boka promotes "Subscribe & Save 15% Every Order" across its site. Its FAQ says "Subscriptions can be cancelled at any time," and adds: "If you choose to cancel after your order has been processed you will still receive and be charged for that Boka order." In other words, cancel before the next order is processed, not after the charge. That timing detail also comes up in the reviews in Part 12.

Shipping

Boka's shipping policy lists one to two business days to process an order and up to five business days for delivery, with the free-shipping thresholds given in Part 9.

Part 11

Where to buy Boka

According to Boka's own press release, the brand is sold on boka.com, including subscriptions, at Walmart in stores and online, on Amazon, and at Target, CVS, Sprouts, Erewhon, H-E-B and Fresh Thyme. Boka's store locator needs your location to show results, so check it for stock near you. To see Boka's price and disclosures next to 10 other brands, read our best hydroxyapatite toothpaste 2026 comparison.

Two practical notes. If price matters, compare the in-store price with boka.com's 3-pack and subscription prices, because the per-tube math above can beat a single tube in a shop. And on marketplaces, check that the seller is Boka or the marketplace itself, since third-party sellers set their own return terms. We do not link to any store here; Boka's own site and the retailers are easy to find by name.

A further practical point for shoppers outside the US: the channels in Boka's release are all American. We did not check international shipping beyond the Canada threshold in the shipping policy.

Part 12

What reviewers say, on and off Boka's site

There are three review records, and they tell different stories. Here they are side by side, with where each comes from.

Swipe sideways on mobile. As displayed on 25 September 2026; counts on these platforms change daily.

The two records measure different things. On-site ratings come mostly from buyers who stayed and were asked to rate the product. Trustpilot and the BBB tend to collect people with a problem, often about service rather than the paste. Twenty-eight Trustpilot reviews for a brand of this size is a very small sample, and it would be unfair to treat it as the verdict of Boka's customers. It is useful for one thing: it shows what goes wrong when something does.

The recurring complaint themes

On Trustpilot, the one- and two-star reviews repeat a handful of themes: customer service that reviewers describe as unresponsive, subscription charges that reviewers say they did not authorize or could not cancel, shipping delays, and a smaller group of reviewers who report tooth damage, discoloration or cavities despite using the paste. Those are the reviewers' accounts, and we did not verify any individual case.

Two representative quotes, as posted. A reviewer named Em wrote: "They shipped my subscription order without letting me know, to a wrong address...can't cancel." A reviewer named Terry Shaw wrote: "I've been charged on my credit card every 3 months for almost 2 years for a recurring subscription that I never signed up for." Both are readable in full on the Trustpilot profile in the sources. Set them next to the FAQ line in Part 10, that an order already processed will still be charged, and the practical advice writes itself: if you subscribe, note your renewal dates and cancel well ahead of one.

On the positive side, the general consumer roundups that rank for Boka searches tend to praise flavor and comfort for people with sensitive teeth, while the negative side focuses on cost and the smaller set of cavity and canker-sore complaints. We report that as the shape of the public conversation, not as our finding.

The court docket

A federal docket names Essor Group, Inc., the company that operates Boka: Herrera v. Essor Group, Inc., U.S. District Court for the Southern District of New York, case 1:25-cv-04247, filed 21 May 2025. CourtListener records its nature of suit as "Civil Rights: Americans with Disabilities - Other". That is not a product, ingredient or labeling category. A second docket, Silvia Garcia v. Essor Group, Inc. (C.D. Cal. 2:25-cv-11610, filed 5 December 2025), lists no nature of suit on CourtListener, and Essor Group runs more than one brand, so we do not know whether it concerns Boka. A lawsuit is a claim, not a verdict, and we found no court ruling about Boka toothpaste itself as of 25 September 2026. Several websites describe a "Boka toothpaste lawsuit" in detail; the ones we found were attorney marketing pages rather than court records, so we did not use them.

In fairness

What Boka does genuinely well

A review built on documents owes the brand the documents in its favor, and Boka has several. It publishes its full ingredient list in plain text. It publishes a particle size in nanometers, with length and width, which most brands in this category never do. It answers the percentage question openly in its help center instead of ignoring it, even if the answer is no. Its regular pastes are fluoride-free, SLS-free and paraben-free exactly as stated. Its Sensitive paste goes through the FDA's drug-listing route and declares its active at a stated strength.

Boka is also one of the few nano-hydroxyapatite brands that an independent research group has tested by name, and in that test it performed in the same statistical range as most other pastes, fluoride products included. It has national retail distribution, so you can buy a single tube in a store before committing to anything online. It has held its trademark since 2015 and is backed by a known parent company. It names an advisory committee. And when the advertising reviewers ruled against its claims, the company said it would comply, which is how that system is supposed to work.

None of this cancels Parts 4, 6 and 10, and those parts do not cancel this. Both are the record.

Who it suits

Who Boka suits, and who should skip it

Boka makes sense if

You want a fluoride-free toothpaste and have decided that with your dentist. You want nano-hydroxyapatite rather than micro-sized hydroxyapatite and value a stated particle size. You want a paste you can buy in regular stores rather than only online. You like the flavor range, including a mint-free option. Or you want a potassium-nitrate sensitivity paste without fluoride, which the Sensitive formula provides.

Consider something else if

You want to know the nano-hydroxyapatite percentage before you buy, because Boka will not tell you. You want a paste backed by the ADA Seal, which Boka does not carry. Your dentist has recommended fluoride for your caries risk, in which case a fluoride-free paste works against that advice. Or you dislike subscriptions and one-way refund terms; in that case buy single tubes in a store.

And one point regardless of brand: if you have active decay, pain or rapidly worsening sensitivity, no toothpaste choice replaces a dental visit.

Where we fit

Where a nano-hydroxyapatite gum fits next to Boka

We make a gum, so weigh this section accordingly. Minvelle is a chewing gum, meant to sit alongside your paste. It is a xylitol-sweetened chewing gum with 5.7 mg of nano-hydroxyapatite per 1.9 g piece, which is 0.30% by weight, printed on the box. One piece a day, chewed for at least 20 minutes, usually after a meal or coffee when brushing is not practical. Its particle specification, supplied by the manufacturer of the mineral, is rods of 200 nm by 20 to 50 nm. A batch certificate is published, so the lab-tested numbers can be checked.

What it does not have: a clinical trial of its own. We have never run one, and we do not claim one. It contains egg. And it is an add-on between brushings. If you use Boka, keep brushing with it twice a day; the gum just covers a different part of the day. Our comparison of hydroxyapatite paste vs gum explains how the two formats divide the work.

Questions, answered

The things people actually ask

Facts checked on 25 September 2026 from the sources below; if Boka changes its pages, tell us and we will update.

Documents over adjectives. This review set out to answer the most searched question about a well-known nano-hydroxyapatite toothpaste without adding a single characterization of our own. The record turned out to be more favorable in some places and more pointed in others than most review pages suggest. Boka is an established brand with real distribution, a published particle size and one independent lab test to its name. It also withholds the one number a buyer would most like to compare, lost an advertising challenge over its remineralize and whitening claims in 2025, and offers refunds on unused product only. Boka could change the most important line in this article in an afternoon: publish the percentage. We would gladly update the page if it does.
