One thing first: "Boka vs RiseWell" is a nano-versus-micro question as much as a brand question. RiseWell's $12 Original contains no nano-hydroxyapatite at all; only the PRO line does. If you compare Boka with "RiseWell" without naming the tube, you may be comparing a nano paste with a micro one.

At a glance

Boka vs RiseWell, side by side

Swipe sideways on mobile. Boka and RiseWell pages checked 25 September 2026 for our full reviews; study figures from PubMed, resolved 26 September 2026.

Part 1

The active ingredient: nano, micro, and how much

This is the biggest difference and the easiest to miss. Boka uses nano-hydroxyapatite. Its Ela Mint ingredient list shows "Hydroxyapatite*" sixth, footnoted "Nano", and its help centre gives a particle description: nanorods 20 to 80 nm long, typically 50 to 60 nm, and 10 to 15 nm wide. What it does not give is the amount; its help centre says it is "unable to share" the percentage "for proprietary purposes".

RiseWell does the opposite. It publishes the amount and not the particle size. Its Original line "use[s] a 10% concentration of micro-hydroxyapatite", which RiseWell says it sources "from a mine in France", and the PRO FAQ states that PRO combines "Nano and Micro Hydroxyapatite", naming the nano ingredient as 5% NanoXIM CarePaste from the supplier Fluidinova. RiseWell is explicit that the Original is "micro hydroxyapatite ONLY".

So the honest comparison has three corners. Boka: nano, amount undisclosed. RiseWell Original: micro, 10%. RiseWell PRO: 10% micro plus 5% nano. Which matters more to you, knowing the dose or getting nano, decides most of the choice. Our hydroxyapatite toothpaste ranking puts both next to nine other brands on exactly these questions.

A practical note on reading the labels in a shop or on a marketplace listing. Boka marks its hydroxyapatite with an asterisk footnoted "Nano". RiseWell uses the product name: if "PRO" is not in the title, the tube is micro-only, and if you want nano from RiseWell you should also see "Nano-Hydroxyapatite" in the ingredient list. Marketplace listings sometimes blur the two, so check the photo of the ingredient panel before you buy.

Does nano vs micro matter?

Both forms have clinical evidence, in different trials. A one-year randomised trial in young children used microcrystalline hydroxyapatite and found it not inferior to a fluoride children's toothpaste (Paszynska 2021, Sci Rep, PMID 33514787); systematic reviews of nano-hydroxyapatite toothpaste support the nano form for caries prevention too (Wierichs 2022, PMID 35103837). Smaller particles are often argued to penetrate surface defects and dentine tubules better, which is one reason sensitivity-focused pastes favour nano. No trial we found compared a micro and a nano paste head to head for cavities. Our explainer on nano vs non-nano hydroxyapatite goes further.

Part 2

The one study that tested both

Amaechi and colleagues (J Dent 2025, PMID 40744295) is the only PubMed-indexed study we found that tested both brands' pastes, and it tested three of them at once. Researchers created early caries lesions on 160 bovine enamel blocks with a microbial caries model, split them into eight groups of 20, and ran 14 days of pH cycling with three two-minute toothpaste treatments a day. The outcome was the percentage recovery of surface microhardness.

J Dent 2025;161:106006, PMID 40744295, as recorded in PubMed; resolved 26 September 2026. The paper has a published erratum (J Dent 2026).

Read it in both directions. Every product, including both brands and both fluoride pastes, produced significant remineralization. Boka and RiseWell Original were statistically indistinguishable from each other and from most products, including the fluoride pastes. Both were significantly behind the one paste labelled 20% nano. RiseWell PRO was not significantly different from the top performer, but the abstract does not report its number, so we cannot say how close it came. The limits are the usual ones: bovine enamel, a lab model, 14 days, and no measure of cavities in people. The study also lists Boka as "concentration not disclosed", the same gap buyers face.

Part 3

Ingredients, abrasivity and feel

Boka's Ela Mint list runs to 26 ingredients: water, glycerin, hydrated silica, sorbitol, silica, then hydroxyapatite, followed by a foaming agent (sodium lauroyl sarcosinate), several essential oils (peppermint, spearmint, anise, wintergreen, cardamom), xylitol, stevia, and botanical extracts from aloe to mango. It is a conventional paste with a natural-leaning extras list. Boka sells several adult flavours and a kids range, which is the thing Reddit users praise most about it, and a Sensitive paste with 5% potassium nitrate.

RiseWell publishes something almost no brand does: abrasivity. It states an RDA of 85 for the Original and 65 for PRO, and a pH of 8 for both. For context, RDA values below about 250 are within the widely accepted safe limit, and many everyday pastes sit between 50 and 100. We found no RDA figure on Boka's product pages, FAQ or label. If abrasivity matters to you, for example because you have exposed dentine, only RiseWell gives you a number to work with.

On feel, Reddit users describe Boka as a "cloudy gel texture" with some flavours that people either love or find too sweet, and some find it less foamy than conventional pastes. We did not find a comparable volume of feedback on RiseWell's texture; see our round-up of Boka on Reddit for what users say.

Part 4

Claims, advertising and legal record

Boka

In 2025, after a challenge by Procter & Gamble, the maker of Crest, the National Advertising Division of BBB National Programs (case #7412) found that Boka's parent company, Essor Group, had a reasonable basis to say Boka is made with nano-hydroxyapatite, and recommended that it stop claiming the toothpaste "remineralizes" or "fortifies" teeth, along with some whitening and prebiotic claims. The National Advertising Review Board affirmed in July 2025, finding Essor "lacked adequate substantiation" for the challenged claims, and Essor said it would comply. That is advertising self-regulation, not a court ruling. On court records, the one docket clearly naming Essor, Herrera v. Essor Group (S.D.N.Y.), is recorded as a disability-access case, not a product case.

RiseWell

RiseWell's record is in court rather than advertising review. Two class actions filed in 2024 in the Northern District of California, Watkins v. RiseWell LLC, alleged PFAS in the toothpaste; both ended in voluntary dismissal by the plaintiffs, the second with prejudice on 14 August 2025, and no court ruled on the allegations. RiseWell states its products and packaging are "BPA, PFAS, and Phthalate-free". A third case runs the other way: RiseWell LLC v. Happy Tooth Products (D. Utah, filed 6 May 2025), in which RiseWell alleges a competitor used its confidential formula; it was active when we checked. We found no advertising-review decision on RiseWell. Details and docket numbers are in our full RiseWell review.

Neither record tells you whether a paste works. They tell you where each brand's claims have been challenged: Boka on its marketing language, RiseWell on an allegation about contaminants that was withdrawn.

Part 5

Who is behind each brand

Boka. The BOKA word mark (USPTO registration 4965811) was filed on 13 February 2015, lists a first use in commerce of 19 August 2015 and is owned by Boka, LLC, which the register describes as a Minnesota company; it was renewed in 2026. Today Boka is part of Essor Group, Inc., a Chicago consumer-goods company named in both 2025 advertising decisions. The FDA drug directory lists the labeler of the Boka Sensitive paste, which contains potassium nitrate, as Karaka LLC in Chicago, a separate legal name within the same group. Boka's own pages do not name a founder; trade press identifies a co-founder, which we did not verify independently.

RiseWell. RiseWell says it was co-founded by John and Kori Estrada and Kori's brother, Dr. Derek Gatta, whom it describes as a dentist and prosthodontist; we did not check the licence. Its Terms of Use name Illuminati Labs LLC, doing business as RiseWell, as the contracting party under New York law, and the USPTO records RiseWell LLC, a New York company, as the owner of both RISEWELL marks after an assignment update in June 2022. RiseWell's own court filing names Wallsburg Farms, Inc., a Utah corporation, as its toothpaste manufacturer.

Both are established US brands with traceable owners. Boka sits inside a larger consumer-goods group; RiseWell is a smaller, founder-led company that names more of its supply chain.

Part 6

The studies each brand points to

RiseWell ships a research pack of eight items, which our RiseWell review resolved one by one. They include a 2014 narrative review of nano-hydroxyapatite in dentistry (Pepla, PMID 25506416), a 2011 lab study of nano-hydroxyapatite pastes on bovine enamel and dentine (Tschoppe, PMID 21504777), and a 2019 in situ randomised crossover study in which 30 adults wore enamel blocks while using a 10% hydroxyapatite paste or a 500 ppm amine-fluoride paste for 14 days each, with no significant difference in remineralization between them (Amaechi, BDJ Open, PMID 31839988). None of these tested a RiseWell product; they support the ingredient at a stated concentration, which RiseWell matches.

Boka's pages lean on the general hydroxyapatite literature rather than a pack of specific citations, and after the 2025 advertising decisions they no longer carry the remineralize and fortify claims that were challenged. The only PubMed study naming a Boka product is the 2025 lab comparison in Part 2.

Neither brand, then, has a clinical trial on its own paste. The trials that exist, in children and adults, tested other hydroxyapatite pastes at 10%, which is one reason RiseWell's stated 10% is useful: it lets you line the product up with the research. Boka's undisclosed percentage does not.

Kids' pastes

Both brands sell children's pastes. Boka's kids range includes Bubble Gum, Blueberry Dragon Fruit, Strawberry Mango, Watermelon Mint and Orange Cream, all nano-hydroxyapatite with the percentage undisclosed. RiseWell sells a Kids paste in Cake Batter at $12, which is micro-only like the adult Original, and a Kids PRO with micro plus nano at $22. For young children, most paediatric dental guidance still recommends a fluoride toothpaste in a smear or pea-sized amount; a one-year trial of a microcrystalline hydroxyapatite paste in young children found it not inferior to a fluoride children's paste (PMID 33514787), but it tested neither brand. Discuss the choice with your child's dentist.

Part 7

Price, availability and returns

Prices as displayed on each brand's store on 25 September 2026; retail prices differ.

For the base tubes, price is effectively a tie. The practical differences are access and returns: Boka is easier to pick up in a store, RiseWell ships more widely, and RiseWell's written refund policy is more generous because Boka's requires the product to be unused.

Part 8

Reviews and what buyers report

Both brands host very large review counts on their own sites, which are not independent: Boka showed Ela Mint at 4.8 across about 3,900 reviews, and RiseWell showed 6,980 reviews on its Original Wild Mint paste when we checked. The independent records are small and skew negative, as they usually do. Boka's Trustpilot profile showed 2.5 out of 5 from 28 reviews, with recurring themes of customer service and subscription charges; RiseWell's showed 2.8 out of 5 from 18 reviews. Neither sample is large enough to be the verdict of either brand's customers.

On Reddit, Boka dominates the conversation. The most-upvoted Boka thread of 2026 is a user who went back to fluoride after six cavities, with replies strongly defending fluoride, alongside many users who praise Boka's flavours and report less sensitivity. RiseWell comes up far less often in the threads we read. Our round-up of hydroxyapatite toothpaste on Reddit covers the wider conversation.

Part 9

Which one should you buy?

Beyond the toothpaste

Both brands sell a wider range, and the same disclosure pattern carries over. RiseWell's micro-hydroxyapatite also appears in its a-HA Mints ($12 a pack) and Scrubby Floss ($8), and its professional-strength Hydroxyapatite Varnish, sold at $98, contains both micro and nano; its Balancing Mouthwash is xylitol-based and contains no hydroxyapatite. Boka's range adds whitening pastes, a peroxide-free whitening powder, probiotic pastes, floss and mouthwash tablets. If you are comparing hydroxyapatite rinses from either brand, our hydroxyapatite mouthwash guide covers the category and the EU limit of 0.465% for nano-hydroxyapatite in mouthwash.

If you are switching from one to the other

Switching between Boka and RiseWell is low-risk: both are fluoride-free hydroxyapatite pastes with similar lab performance in the one shared study. Three practical points help. If you move from Boka to RiseWell Original, you are moving from nano to micro; if nano matters to you, choose PRO. If you move from RiseWell to Boka, you lose the stated dose and the RDA figure. And whichever you use, the routine matters more than the brand: two minutes, twice a day, spit and do not rinse straight away, floss daily, and keep your check-ups. If your dentist finds new early lesions after the switch, that is the signal to discuss adding fluoride back, which many users on Reddit report doing.

Choose RiseWell if

• you want a stated dose: 10% micro in Original, 10% micro plus 5% nano in PRO;
• you care about abrasivity and want an RDA number;
• you want nano-hydroxyapatite with a stated amount and can pay $22 for PRO;
• you want a refund policy that does not require the tube to be unopened.

Choose Boka if

• you specifically want nano-hydroxyapatite at around $12;
• you want to buy in a store rather than online;
• flavour and variety matter to you, including kids' flavours;
• you accept that the percentage is not published.

Consider neither as a full fluoride replacement if

• you are cavity-prone or your dentist recommends fluoride. Both are fluoride-free, neither has a clinical trial on its own paste, and many users pair either brand with a fluoride product.

Part 10

Where a nano-hydroxyapatite gum fits

Both of these are toothpastes for the two minutes you brush. Neither covers the hours after lunch or coffee, which is when saliva has to do the work of buffering acid and returning minerals. Chewing sugar-free gum for at least 20 minutes after eating increases saliva, and that 20-minute condition is attached to the EU-authorised claim for sugar-free gum. Minvelle adds a stated 5.7 mg of nano-hydroxyapatite per 1.9 g piece to that window, printed on the box. It fits next to Boka, RiseWell or a fluoride paste; it replaces none of them.

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 does not bleach teeth. There is no peroxide in it; at most it helps with surface stains between brushings.
• 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 each brand does well

Boka made hydroxyapatite toothpaste mainstream in the US, publishes a real particle description, performed in line with most pastes in the 2025 lab study, and is the most accessible option in physical stores. Its flavours are the most-praised thing about it among users. RiseWell publishes more of the numbers that matter than almost any brand in the category: percentages for every line, RDA, pH and its nano supplier. It is clear about which tubes contain nano, and it names its co-founder, a dentist, and its manufacturer in court filings. Both are legitimate, established brands; the differences are in what each chooses to disclose.

How we checked

Method and conflict of interest

This comparison draws on our full reviews of Boka and RiseWell, both checked against the brands' own pages, USPTO, court dockets, advertising-review decisions, FDA databases and review platforms on 25 September 2026, and re-resolves the shared study in PubMed on 26 September 2026. We did not buy or lab-test either paste. Minvelle sells a nano-hydroxyapatite gum, not a toothpaste; neither brand's result affects our business directly, but we have an interest in hydroxyapatite generally.

The verdict

Boka vs RiseWell, in one paragraph

RiseWell wins on disclosure: it states its percentages, abrasivity and pH, and its PRO line gives you stated nano plus micro at $22. Boka wins on access and variety: nano-hydroxyapatite at about $12 in stores, with more flavours, but with the percentage withheld and a 2025 advertising decision against some of its claims. In the one lab study that tested both, the base pastes performed alike. If you want the numbers, choose RiseWell; if you want nano off the shelf, choose Boka; if you are cavity-prone, keep fluoride in the picture either way.
