Quick Answer
If you’re looking for the best non-toxic toothpaste, our top pick is Risewell Mineral Toothpaste — co-founded by a prosthodontist, 10% micro-hydroxyapatite at a disclosed concentration, and one of the longest track records of any hydroxyapatite brand in the US. For sensitive teeth and an oral microbiome-focused formula backed by a peer-reviewed study, Fygg Nano-Hydroxyapatite Toothpaste with Prebiotics is worth the upgrade — and unlike the others, it’s designed to be left on the teeth without rinsing, which maximizes how long the hydroxyapatite stays in contact with enamel. For the easiest first swap you can grab in person, Boka is available at Target. For kids specifically, Risewell Kids uses the same formula in a non-mint flavor, and Fygg Kids is the pick for sensitivity with a no-rinse design built around how kids actually brush. Every option in this guide is fluoride-free — here’s what we use instead, and why.
Why I Started Looking at Toothpaste
I got to toothpaste the same way I get to most things on this site: I read the ingredient list on the tube in our bathroom and couldn’t explain what half of it was doing there. Toothpaste is one of those products we use twice a day, don’t rinse out completely, and hand to our kids before they’ve fully learned not to swallow it. That combination — daily use, low rinse-off, small bodies — makes it worth a closer look.
This guide focuses on hydroxyapatite toothpaste, the main fluoride-free category with real dental research behind it right now. I’ve compared six brands across ingredients, remineralization approach, and price. And if you’re working through the rest of your family’s personal care routine, the non-toxic deodorant guide and non-toxic hand soap guide apply the same ingredient-first thinking to two other daily-use products.
Remineralization: What We’re Actually Looking For
Teeth lose and regain minerals all day long as acids from food and bacteria wear down enamel, and saliva — along with what’s in your toothpaste — helps rebuild it. That rebuilding process is remineralization, and it’s the real job a toothpaste needs to do. Cleaning is almost secondary.
Hydroxyapatite is the mineral doing that work in every product in this guide. It’s naturally occurring, makes up the majority of tooth enamel already, and works by physically filling in worn or weakened spots on the tooth surface. Some brands use micro-hydroxyapatite (larger particles, longer track record), others use nano-hydroxyapatite (smaller particles that can get into finer cracks), and a couple use both. Neither is universally “better” — it depends on concentration and the specific formula, which is why I’ve noted each brand’s approach below rather than treating hydroxyapatite as one interchangeable ingredient.
Ingredient Breakdown: What’s Actually in These Tubes
Hydroxyapatite toothpaste ingredient lists look unfamiliar at first, but most ingredients are doing one of three jobs: remineralizing, cleaning gently, or holding the paste together. Here’s what shows up most often and why it’s there.
Hydroxyapatite (micro or nano) — The core active ingredient in every pick here. A calcium-phosphate mineral that makes up the majority of natural tooth enamel. In toothpaste form it deposits onto the tooth surface and fills in worn spots or micro-cracks — similar to spackling a wall rather than hardening existing material the way fluoride does.
Xylitol — A sugar alcohol in nearly every formula here. It doesn’t remineralize on its own, but cavity-causing bacteria can’t metabolize it the way they metabolize sugar, so it helps starve the bacteria that produce the acid that wears down enamel.
Hydrated Silica — A mild, naturally derived abrasive that provides gentle polishing and stain removal without scratching enamel the way harsher abrasives can.
Calcium Carbonate — Another mild abrasive, often used alongside silica for cleaning and light polishing.
Glycerin and Sorbitol — Both are humectants that keep the paste from drying out in the tube. Texture ingredients, not active ones.
Propanediol — A plant-derived solvent that helps keep the formula smooth and stable; functions similarly to glycerin.
Potassium Cocoate — A coconut-oil-derived mild surfactant used in place of SLS to create a small amount of lather without the detergent effect that strips the mouth’s natural bacteria.
Cellulose Gum / Xanthan Gum / Sclerotium Gum — Plant-derived thickeners that give the toothpaste its texture and keep ingredients evenly suspended rather than separating in the tube.
Sodium Gluconate — A mineral-chelating ingredient that helps stabilize the formula and supports the calcium-binding environment hydroxyapatite needs to work effectively.
Chicory Root (Inulin) and L-Arginine — Both act as prebiotics, feeding the beneficial bacteria in the mouth rather than wiping out bacteria indiscriminately. This is the ingredient pairing behind Fygg’s and SuperTeeth’s oral microbiome positioning.
CoQ10 — An antioxidant compound associated with gum tissue support, included in SuperTeeth’s formula separately from the enamel work hydroxyapatite does.
Potassium Nitrate — Found in Boka’s Sensitive line; a clinically recognized ingredient for calming nerve sensitivity inside the tooth.
Fluoride: Why We Don’t Include It Here
Fluoride works, and the dental research behind it is long-standing — this guide isn’t built on the idea that fluoride is dangerous at the levels used in toothpaste. The reasoning for leaving it out is simpler: many families today already get fluoride from municipal water, mouthwash, and professional treatments, and are specifically looking for a toothpaste that lets them dial back total exposure without giving up a remineralizing ingredient. This guide exists for that reader.
If your family uses fluoridated water and your dentist recommends fluoride toothpaste for your specific dental history, that conversation is worth having with them directly. What we can say is that hydroxyapatite has a growing body of research showing it remineralizes enamel effectively without fluoride, which is why every option below uses that approach.

The Best Non-Toxic Toothpastes
1. Risewell Mineral Toothpaste — Best Overall
Best for: The whole family; first-time switchers who want a proven formula with a dentist-founded track record.
Risewell was one of the first hydroxyapatite brands to gain real traction in the US — co-founded by a prosthodontist, with a dental advisory panel that’s been involved since the beginning. That track record matters in a category where newer brands make bold claims without the real-world use data to back them up. The Original line uses 10% micro-hydroxyapatite, a concentration the brand discloses clearly — which is worth noting because many hydroxyapatite brands don’t publish their exact concentration at all. The formula also includes xylitol, silica, and calcium carbonate for gentle cleaning, with no SLS, no parabens, and no propylene glycol. The ingredient list is short and every component has a clear function.
Risewell was co-founded by a prosthodontist, and the brand’s dental advisory panel notes that hydroxyapatite has gained broad acceptance in dentistry for its ability to bond to tooth surfaces without toxicity or inflammation. There’s also a flavorless version, which is handy for kids who resist minty flavors or anyone with sensitivity to essential oils.
Risewell Original vs. Risewell PRO — which one do you actually need?
Both skip fluoride, SLS, and parabens. The difference is how much hydroxyapatite you’re getting and in what form.
| Risewell Original | Risewell PRO | |
|---|---|---|
| Hydroxyapatite type | 10% micro-hydroxyapatite | 5% nano (NanoXIM) + 10% micro |
| Best for | Everyday maintenance, first-time switchers, kids | Sensitivity, visible enamel wear, stronger remineralization goals |
| Price tier | Budget (~$12 direct) | Premium (~$22 direct) |
For most families starting out, the Original is the right entry point — it’s the formula with the longest track record on the market and a gentler price. PRO makes sense specifically if a dentist has flagged enamel thinning or sensitivity, since the added nano-hydroxyapatite is designed to reach finer surface cracks the micro-only formula may not fully address.
2. Fygg Nano-Hydroxyapatite Toothpaste with Prebiotics — Best for Sensitive Teeth
Best for: Households dealing with tooth sensitivity; families who want an oral microbiome-focused formula.
Fygg was developed by functional dentists specifically around protecting the oral microbiome — no essential oils, no emulsifiers, no detergents, and no SLS on top of being fluoride-free. The formula uses nano-hydroxyapatite alongside L-arginine, xylitol, and chicory root, which functions as a prebiotic to feed beneficial bacteria rather than wiping everything out indiscriminately.
One distinguishing instruction worth knowing: Fygg is designed to be used without rinsing afterward. You brush, spit, and leave it on — no water rinse. This keeps the hydroxyapatite in contact with enamel for longer after brushing, which is the mechanism the brand believes maximizes the remineralization window. For kids especially, this is a meaningful advantage since young children often rinse instinctively and don’t fully keep fluoride-free toothpaste on their teeth long enough to do much work. With Fygg, the no-rinse approach sidesteps that entirely.
It’s also the only brand in this guide backed by a published peer-reviewed study. A 2025 University of Texas Health San Antonio trial tested Fygg against seven other toothpastes — including Boka and two fluoride controls — and found Fygg produced the highest remineralization of the group, statistically matching the 5,000 ppm prescription-strength fluoride toothpaste in the study.
Two honest caveats worth knowing: it’s an in vitro study using bovine enamel rather than a clinical trial in people’s mouths, and it was funded by Oral Microbiome Solutions, LLC, which appears affiliated with Fygg. That’s disclosed in the published paper. The study was peer-reviewed and published in the Journal of Dentistry — but it’s the kind of detail that deserves to be visible rather than buried.
3. SuperTeeth Prebiotic Mineral Toothpaste — Best for Families Wanting One Tube for Everyone
Best for: Families with kids aged 3+ who want one toothpaste for everyone; households interested in gum support alongside enamel remineralization.
SuperTeeth hits a nice middle ground: hydroxyapatite for remineralization, prebiotics and CoQ10 for gum support, and a shorter, more recognizable ingredient list than some of the more clinical-feeling premium brands. Free of fluoride, sulfates, parabens, SLS, artificial flavors, and dyes, and formulated gentle enough for kids three and up — which matters a lot when you’re trying to standardize what’s in the bathroom cabinet rather than running two separate toothpaste systems.
4. Boka Ela Mint — Best for In-Store Availability
Best for: Families who want to pick up hydroxyapatite toothpaste at Target without ordering online.
Boka is the only hydroxyapatite toothpaste in this guide available at Target, making it the go-to if you want to grab something in person without ordering online. The Ela Mint formula uses nano-hydroxyapatite with green tea extract and xylitol, peroxide-free, SLS-free, paraben-free, and free of artificial dyes. Boka also makes a dedicated Sensitive line with potassium nitrate for households dealing with tooth sensitivity specifically.
Two things worth knowing before you buy. First, a 2025 independent test published by Lead Safe Mama found trace levels of lead, arsenic, and mercury in Boka’s Ela Mint formula. Boka confirmed the levels fall within FDA guidelines and California Proposition 65 limits — which are among the most stringent heavy metal standards in the US — and pointed out that trace heavy metals are naturally present in many mineral-derived ingredients, including hydroxyapatite itself. The levels are legally compliant and the toothpaste is spit out rather than swallowed, which limits bioavailability. But it’s the kind of detail we think you should know. Second, in May 2025, the National Advertising Division (NAD) recommended that Boka discontinue its remineralization and whitening claims after a challenge brought by Procter & Gamble. The ruling wasn’t that hydroxyapatite doesn’t remineralize — the ingredient research supports that it does — but that Boka hadn’t conducted studies on its specific finished formula to support those claims. Boka ultimately agreed to comply.
None of this makes Boka a harmful product. It’s still a fluoride-free, SLS-free formula at a fair price point with wide availability. We’re including it because those practical qualities matter, and naming these issues rather than burying them is exactly the kind of transparency this site exists to provide.
5. Davids Hydroxi — Best for Sustainability-Minded Families
Best for: Families who want a certified B Corp, a metal recyclable tube, and a short ingredient list; eco-conscious households.
Davids is a Certified B Corp making toothpaste in the USA with a commitment to sustainability that runs through everything — the tube is made from stainless steel and fully recyclable, the packaging is minimal, and the ingredient list is deliberately short. The Hydroxi line applies that same philosophy to nano-hydroxyapatite: remineralizing, sensitivity-supportive, SLS-free, fluoride-free. Calcium carbonate and xylitol round out the formula.
If the metal tube and B Corp credentials matter to your family — and for many families working through a low-tox routine, they do — Davids delivers those alongside a clean formula at a budget-accessible price.
For Kids Specifically
Every toothpaste in this guide is safe for children, but two formulas are designed specifically for younger brushers.
Risewell Kids Cake Batter uses the same 10% micro-hydroxyapatite formula as the Original but in a Cake Batter flavor that makes the switch easier for kids who resist mint. The flavorless version of the Original also works well for young children who are sensitive to any flavoring. Safe to swallow in normal brushing amounts.

Fygg Kids is the pick for children with sensitivity or families who want a prebiotic-focused formula. Same formula as the adult version — no essential oils, no SLS, no detergents, safe to swallow. Crucially, Fygg is designed to be used without rinsing: brush, spit, don’t rinse. For kids who rinse immediately out of habit and don’t let toothpaste do its work, this no-rinse design keeps the hydroxyapatite on the enamel long enough to actually remineralize. It’s one of the most practical advantages of the formula for younger brushers.
For children under 3, talk to your pediatric dentist before switching from a fluoride formula — this is a conversation worth having based on your child’s specific dental history and your local water fluoridation levels.
Is hydroxyapatite toothpaste actually as effective as fluoride? The research on hydroxyapatite is real and growing, including comparative studies against fluoride for cavity prevention. It’s a smaller and newer body of research than the decades behind fluoride, but well-supported enough that many family dentists have started recommending it as a genuine alternative. We think it’s a reasonable, well-supported choice for families who want to reduce total fluoride exposure — not a claim that it’s definitively superior in every measure.
Is nano-hydroxyapatite safe for kids to swallow? Every brand in this guide markets its formula as safe to swallow in normal toothpaste amounts, which is part of why several are positioned specifically for young children. As always, supervise young brushers and follow the amount guidance on the tube.
Can I alternate between hydroxyapatite and fluoride toothpaste? Yes. There’s no conflict in alternating, and some families use a fluoride toothpaste for one brushing session and a hydroxyapatite formula for another, depending on their dentist’s guidance.
Why doesn’t this toothpaste foam much? Foaming comes from SLS or a similar detergent, which every brand here intentionally leaves out. It takes a few days to adjust to the lower-foam texture, but it doesn’t mean the toothpaste isn’t cleaning effectively.
What’s the difference between micro and nano-hydroxyapatite? Micro-hydroxyapatite has the longer research history and larger particle size. Nano-hydroxyapatite uses smaller particles specifically designed to reach finer surface cracks in enamel. Neither is definitively better — concentration and formula matter more than particle size alone.
Is this safe for toddlers? Risewell’s flavorless version and SuperTeeth’s formula are specifically designed to be safe for young children including those who may accidentally swallow some toothpaste. If your child is under 3, talk to your pediatric dentist before switching from a fluoride formula.
Bottom Line
Risewell is the go-to starting point for most families — EWG Verified, well-priced, and the formula with the longest track record in the hydroxyapatite category. Fygg is the upgrade for sensitive teeth, backed by peer-reviewed research, and the best choice for kids who need something with no essential oils. Boka is the only one available at Target if you want to pick something up in person — just go in knowing about the 2025 NAD ruling and heavy metal testing. SuperTeeth is the best one tube for the whole family including kids 3 and up. Davids Hydroxi is for families where the B Corp certification, metal recyclable tube, and short ingredient list matter alongside the formula.
The goal isn’t perfection — it’s finding the option that fits your family’s routine and actually gets used.
