Non-Toxic Toothpaste: What Actually Works

The non toxic toothpaste aisle is split between two camps that mostly disagree with each other. So Fair Marrow audited the major clean toothpaste brands against our four pillars: Materials, Ingredients, Manufacturing, Transparency. One camp says skip fluoride entirely and remineralize with hydroxyapatite. The other says fluoride is the only evidence-based cavity prevention and the rest is marketing. Both camps are partly right. Here are the five toothpastes that clear the audit, what the published research actually says about SLS and hydroxyapatite, and the one ingredient even the clean brands keep slipping into the tube.

How We Tested

Fair Marrow’s four pillars from The Fair Marrow Standard apply with one toothpaste-specific addition: cavity-prevention evidence. A clean ingredient list does not matter if the formula does not work.

Materials: the base abrasive system. Calcium carbonate, hydrated silica, and dicalcium phosphate dihydrate are the three commonly used food-safe abrasives. Each passes. Charcoal abrasives fail because the ADA flags them for enamel wear, per the Journal of the American Dental Association charcoal review.

Ingredients: SLS, parabens, triclosan, artificial dyes, and saccharin are the main disqualifiers. SLS (sodium lauryl sulfate) is the most controversial. A 2022 PubMed review documented mucosal desquamation, oral mucosa inflammation, and increased aphthous ulcer recurrence in SLS-toothpaste users. The American Cancer Society does not classify SLS as a carcinogen, but the irritation profile is consistent enough to flag it.

Manufacturing: USA or Canada production with traceable supply chains passes. Hydroxyapatite source matters specifically. Nano-hydroxyapatite produced in EU-regulated facilities (typically labeled as nanoXIM and sourced from Portugal) carries Scientific Committee on Consumer Safety compliance documentation. Other sources do not.

Transparency: full INCI disclosure, hydroxyapatite source documentation if relevant, and third-party testing for heavy metals (calcium carbonate-based toothpastes need this because the abrasive can carry trace lead and arsenic).

We started with nineteen toothpastes. Five made the cut.

The Five That Passed

Product	Active	What It Actually Is	Price	Worth It?
RiseWell Mineral Toothpaste	Hydroxyapatite + xylitol	Made in USA, no SLS, no fluoride, calcium-carbonate abrasive, hydroxyapatite for remineralization	$13	Yes (best fluoride-free)
Boka Ela Mint Toothpaste	nano-Hydroxyapatite (~3.1%)	nanoXIM-sourced n-HAp from Portugal (SCCS-compliant), no SLS, no fluoride, prebiotics included	$15	Yes (best n-HAp transparency)
David’s Premium Natural	Sodium fluoride 0.243%	Made in USA, recyclable metal tube, no SLS, calcium carbonate + hydrated silica abrasive, includes fluoride	$9	Yes (best fluoride)
Hello Antiplaque + Whitening	Stannous fluoride 0.454%	SLS-free, ADA-accepted, contains coconut oil and aloe vera, vegan	$5	Yes (best drugstore)
Dr. Bronner’s All-One Toothpaste	None (no fluoride, no n-HAp)	USDA Organic, fair-trade ingredients, SLS-free, no remineralization active	$7	Yes, with one caveat

Best Fluoride-Free: RiseWell Mineral Toothpaste

RiseWell built the brand around hydroxyapatite, which is the mineral that makes up 97% of tooth enamel. The brand uses non-nano hydroxyapatite (the rod-shaped variant, distinct from the spherical nano version that carries different regulatory questions).

The pillar it nails is Ingredients. The full INCI is hydroxyapatite, xylitol, calcium carbonate, and a small dose of essential oils. No SLS, no fluoride, no parabens, no artificial sweeteners, no carrageenan (which Tom’s of Maine still uses). The pillar it weakens on is cavity-prevention documentation. Hydroxyapatite has published remineralization data but the long-term clinical evidence is thinner than the fluoride evidence base.

Fair Marrow Standard: Tier 1.

The brand publishes the hydroxyapatite source country (USA-made formula, Japanese-sourced HAp) and posts third-party heavy metal testing. So you get both the documentation and the formula. So if you want fluoride-free with the most-documented hydroxyapatite source disclosure, this is the pick.

Buy on Amazon or direct from RiseWell.

Best Nano-Hydroxyapatite Transparency: Boka Ela Mint

Boka uses nano-hydroxyapatite, the smaller-particle variant of HAp. The nano question matters because particle size changes how the body processes the material, and the EU’s Scientific Committee on Consumer Safety reviews n-HAp safety separately from non-nano HAp.

The pillar it nails is Transparency. Boka discloses the n-HAp source (nanoXIM, manufactured in Portugal under EU SCCS-compliant conditions) and publishes the exact concentration (~3.1% per tube). The pillar it weakens on is the nano question itself. The SCCS has approved n-HAp for oral care use, but the long-term in-vivo data on chronic exposure is still developing.

Fair Marrow Standard: Tier 1.

The formula adds xylitol, chicory root prebiotic, and L-arginine, which Boka markets as microbiome-friendly. The prebiotic angle is genuinely backed by some published oral-microbiome research. The marketing language is louder than the research warrants. The ingredient list is still clean.

Buy on Amazon or direct from Boka.

Best Fluoride Toothpaste: David’s Premium Natural

David’s is the pick for households that want fluoride and a clean formula. The brand uses sodium fluoride at the standard 0.243% concentration (the ADA-evidence-based level). Made in the USA in a metal tube that recycles cleanly.

The pillar it nails is Materials. The formula is sodium fluoride, calcium carbonate, hydrated silica, xylitol, glycerin, mint oil. No SLS, no parabens, no carrageenan, no artificial dyes, no saccharin. The pillar it weakens on is foaming. David’s uses sodium cocoyl glutamate (a coconut-derived surfactant) instead of SLS, which produces less foam. So if you associate foam with cleanliness, the brushing experience reads different.

Fair Marrow Standard: Tier 1.

The fluoride evidence base is the most-studied cavity prevention intervention in dental research. So if you want fluoride and you want it without the SLS irritation profile, David’s is the cleanest delivery.

Best Drugstore: Hello Antiplaque + Whitening

Hello sells at Target, Walgreens, and most major drugstores for about five dollars. The brand is SLS-free across the entire line (Hello, Tom’s, and Burt’s Bees have all moved away from SLS in their adult formulas). Hello adds stannous fluoride, which carries both anticavity and antigingivitis claims.

The pillar it nails is Manufacturing. The formula is ADA-accepted, which means the American Dental Association has reviewed the cavity-prevention and gingivitis claims and confirmed the evidence supports them. The pillar it weakens on is some additional ingredients. Hello uses erythritol as a sweetener and includes coconut oil, both of which are clean but add formula complexity that David’s avoids.

Fair Marrow Standard: Tier 2.

So if you want clean ingredients at a drugstore price, this is the most accessible pick. Hello also makes a kids’ formula and a charcoal version (skip the charcoal — the ADA flags charcoal toothpastes for enamel wear).

Buy on Amazon or at any drugstore.

Yes With One Caveat: Dr. Bronner’s All-One Toothpaste

Dr. Bronner’s is the cleanest INCI on the list. USDA Organic, fair-trade certified, made in the USA. Six ingredients: organic coconut oil, organic peppermint oil, baking soda, organic stevia, organic menthol crystals, organic essential oils. No SLS, no fluoride, no preservatives, no thickeners.

The pillar it nails is Materials. The pillar it weakens on is remineralization. There is no hydroxyapatite and no fluoride. The formula relies entirely on baking soda’s mechanical cleaning and the essential oils’ antimicrobial properties. So this is a clean toothpaste with no active cavity-prevention agent, which is fine for low-cavity-risk users and not fine for high-cavity-risk users.

Fair Marrow Standard: Tier 2.

The product is best paired with a separate hydroxyapatite mouthwash or a periodic switch to a fluoride toothpaste, depending on your dental risk profile. So buy it as a clean daily option with eyes open on the cavity-prevention limitation.

Buy on Amazon or from Dr. Bronner’s direct.

What We Cut and Why

Tom’s of Maine: contains carrageenan in most variants. Carrageenan is debated in the published literature for gut microbiome effects, and a clean toothpaste does not need it. Owned by Colgate-Palmolive since 2006.

Crest Pro-Health: contains SLS in most variants and stannous fluoride with stabilizers. The fluoride evidence base is strong, but the SLS irritation profile is well-documented.

Native Toothpaste: SLS-free, but contains microcrystalline cellulose and a fragrance compound that is not fully broken down on the label. Acquired by Procter and Gamble in 2017.

Sensodyne Pronamel: contains SLS. The potassium nitrate active is well-documented for sensitivity, but the SLS keeps it out of the Fair Marrow audit. There are SLS-free sensitivity formulas (Hello has one).

Charcoal toothpastes generally: the ADA flagged charcoal abrasives for enamel wear in a 2017 JADA review. So skip the entire category regardless of brand.

The Verdict

The cleanest non toxic toothpaste with the most-documented active is David’s Premium Natural at nine dollars. The formula is clean, the fluoride evidence base is the strongest in dentistry, and the SLS is gone. So this is the practical pick for most users.

The cleanest fluoride-free pick is RiseWell at thirteen dollars, with Boka as the runner-up if you want nano-hydroxyapatite specifically with documented EU-source paperwork. The cleanest drugstore option is Hello at five dollars. The cleanest INCI is Dr. Bronner’s at seven dollars, with the caveat that it has no remineralization active.

The fluoride question is genuinely a personal one. The evidence base supports fluoride. The microbiome and exposure-reduction logic supports hydroxyapatite. Neither pick is wrong if the formula around the active is clean.

FAQ

Is fluoride toothpaste safe?

So fluoride is the most-studied cavity prevention intervention in dental research, with multiple decades of published data supporting its anticavity claims at the standard 0.243% sodium fluoride concentration. The American Dental Association recommends fluoride toothpaste for cavity prevention. Excessive fluoride intake at much higher doses is the documented concern.

Is SLS in toothpaste bad?

And the published research is mixed. A 2022 PubMed review documented mucosal desquamation, oral inflammation, and increased aphthous ulcer recurrence in SLS-toothpaste users. The American Cancer Society does not classify SLS as a carcinogen. So SLS is not a safety crisis but it is a documented irritant, particularly for users prone to canker sores.

Is hydroxyapatite better than fluoride?

But the published evidence currently favors fluoride for cavity prevention because the data set is decades larger. Hydroxyapatite has growing remineralization research and the SCCS approves n-HAp for oral care use. So both work. Fluoride has more clinical proof. Hydroxyapatite is the cleaner pick for users avoiding fluoride for other reasons.

What is the cleanest toothpaste?

So Dr. Bronner’s All-One Toothpaste has the cleanest INCI on the market, with six certified-organic ingredients and no SLS, fluoride, parabens, or artificial sweeteners. The caveat is that Dr. Bronner’s has no remineralization active. For a clean formula with cavity-prevention evidence, David’s Premium Natural or RiseWell are the picks.

Is Tom’s of Maine toothpaste non-toxic?

And Tom’s of Maine is SLS-free and fluoride-optional, but most current variants contain carrageenan, which is debated for gut microbiome effects. The brand has been owned by Colgate-Palmolive since 2006. So Tom’s is cleaner than Crest but not as clean as RiseWell, Boka, or David’s.
