Is Boka Toothpaste Clean?

📅 Updated February 2026⏱️ 4 min readNEW

TL;DR

Boka makes an effective fluoride-free toothpaste that scores well on EWG, but we give it a caution rating. In 2025, independent lab tests detected trace amounts of lead, arsenic, and mercury in their formulas. While legally compliant, there are cleaner hydroxyapatite options available.

🔑 Key Findings

1

Scores a Low Hazard (1-2) rating on EWG for most flavors.

2

Pioneered the use of nano-hydroxyapatite (n-Ha) as a fluoride alternative in the US.

3

Independent 2025 testing found trace heavy metals in both adult and kids' formulas.

4

Hides the exact concentration percentage of their active ingredient (n-Ha).

The Short Answer

Boka is arguably the brand that made nano-hydroxyapatite mainstream in America. Their Ela Mint toothpaste is a massive bestseller for people looking to ditch fluoride without sacrificing cavity protection.

But we currently give Boka a caution rating. While the ingredients label looks pristine and scores a "Low Hazard" on EWG, independent 2025 lab tests detected trace amounts of lead, arsenic, and mercury in multiple Boka formulas.

Why This Matters

Heavy metal contamination is the dirty secret of the "clean" personal care industry. Because the FDA classifies fluoride-free toothpaste as a cosmetic, brands are legally allowed to have up to 10,000 parts per billion (ppb) of lead in their formulas. What Toothpaste Ingredients Are Harmful

Boka maintains that their products are completely safe and comply with California Prop 65, the strictest heavy metal standard in the country. Since toothpaste is spat out, exposure is technically minimal compared to contaminated food.

But for health-conscious consumers, legal limits don't equal safe limits. When you are putting a product in your mouth twice a day—especially if you're buying it for young children—trace levels of lead and arsenic are a valid reason to seek out cleaner alternatives. Is Kids Toothpaste Safe

What's Actually In Boka Toothpaste

Boka's ingredient list is generally free of the worst offenders, but it's not completely perfect.

  • Nano-hydroxyapatite (n-Ha) — A biomimetic mineral that makes up 97% of your tooth enamel. It naturally remineralizes teeth and reduces sensitivity. Fluoride Vs Hydroxyapatite
  • Sodium Lauroyl Sarcosinate — A milder foaming agent than standard sulfates. It's safer than SLS, but it's still a synthetic surfactant. Is Sls In Toothpaste Bad
  • Xylitol — A natural sugar alcohol that starves cavity-causing bacteria and prevents plaque buildup.
  • Trace Heavy Metals — Independent 2025 testing found detectable levels of lead, arsenic, and mercury in both the Ela Mint and Kids Orange Cream formulas.

What to Look For

Green Flags:

  • No SLS or Fluoride — Boka skips the harsh foaming agents and controversial neurotoxins.
  • Biocompatible Minerals — Nano-hydroxyapatite is proven to reverse early decay just as effectively as fluoride.

Red Flags:

  • Proprietary Concentrations — Boka refuses to disclose the exact percentage of n-Ha in their toothpaste, making it hard to compare to clinical studies.
  • Heavy Metal Detection — Trace amounts of lead and mercury were found in recent third-party lab testing.

2. Demand transparency. Brands should disclose their exact active ingredient percentages and publish their heavy metal testing.

3. Don't panic if you use it. Boka is still significantly safer than conventional brands, but there is room for improvement in their sourcing.

FAQ

Is Boka better than fluoride toothpaste?

Studies show that nano-hydroxyapatite is just as effective as fluoride at remineralizing teeth and preventing cavities. It also works better for reducing tooth sensitivity without the toxicity concerns of fluoride. Is Hydroxyapatite As Good As Fluoride

Did Boka test positive for lead?

Yes, in early 2025, independent lab tests from Lead Safe Mama detected trace amounts of lead, arsenic, and mercury in Boka's Ela Mint and Kids Orange Cream flavors. While these levels are fully legal under FDA cosmetic guidelines, they raise red flags for clean living advocates.

Is it safe to swallow Boka toothpaste?

Because it is fluoride-free, Boka is generally considered safe if accidentally swallowed. However, due to the recent trace heavy metal findings, you should still encourage kids to spit it out completely. Is Swallowing Toothpaste Dangerous

Miracle Tooth Powder

VanMan's

Community-funded 2025 lab reports found incredibly high levels of lead and arsenic, along with detectable cadmium and mercury in this powder. The toxicant levels explicitly violate Washington State’s strict 2025 limit of 1,000 parts per billion (ppb) for lead in cosmetics.

Avoid
🚫

Dirty Mouth Tooth Powder (Bubblegum)

Primal Life Organics

Marketed directly to children, this powder tested at an alarming 7,800 ppb of lead in March 2025 third-party lab tests. While technically legal under the FDA's outdated 10,000 ppb cosmetic allowance, this severely exceeds state health limits for pediatric exposure.

Avoid
🚫

Cool Mint Remineralizing Tooth Powder

Just Ingredients

June 2025 lab tests revealed dangerous levels of arsenic and lead hovering near the 1,000 ppb threshold. The formula relies on unpurified bentonite clay, a geological ingredient that inherently concentrates heavy metals from the soil.

Avoid
🚫

Clean Toothpaste (Fluoride-Free)

Truvani

Despite its 'clean' marketing claims, 2025 independent tests detected trace amounts of mercury, lead, cadmium, and arsenic. The formulation uses calcium carbonate and hydrated silica, two mineral abrasives well-documented as frequent vectors for heavy metal contamination.

Avoid
🚫

Natural Toothpaste

Uncle Harry's

This clay-based paste carries a California Proposition 65 warning specifically for lead exposure. Because bentonite clay naturally absorbs soil metals during its formation, complete purification of heavy metals is virtually impossible.

Avoid
⚠️

Kid's Natural Toothpaste (Outrageous Orange Mango)

Tom's of Maine

Independent 2025 laboratory screens flagged this specific pediatric flavor for detectable lead levels. Although it complies with federal FDA limits, the presence of any neurotoxin in a product that young children frequently swallow is a valid concern.

Use Caution
⚠️

Nakedpaste Fluoride Free Toothpaste

Hello

Recent 2025 laboratory screens detected trace amounts of lead in the kids' watermelon flavor. While the ingredient list appears clean, the sourcing of its natural mineral abrasives raises mild contamination concerns for health-conscious consumers.

Use Caution
⚠️
3D White Charcoal

Crest

This whitening paste incorporates activated charcoal, which the American Dental Association explicitly warns can be excessively abrasive. High-abrasion formulas can permanently damage cosmetic dental bonding and wear away natural enamel over time.

Use Caution
🚫

Advanced Whitening

Ultrabrite

This conventional paste scores an exceptionally high 133 on the Relative Dentin Abrasivity (RDA) index. Dental professionals consider products with an RDA over 100 to be highly abrasive, risking long-term dentin exposure and permanent tooth sensitivity.

Avoid
⚠️

Extra Whitening Toothpaste

Sensodyne

While effective at desensitizing nerves, 2025 independent testing reported by Gizmodo found detectable levels of lead in this formula. Furthermore, it scores a 104 on the RDA index, classifying it as a highly abrasive option compared to their Pronamel line.

Use Caution
⚠️

All-One Toothpaste

Dr. Bronner's

This paste is formulated with citric acid, an ingredient that lowers oral pH and can actively erode tooth enamel. It also uses potassium cocoate, a foaming agent linked to dry mouth, and tested positive for trace lead in early 2025 screens.

Use Caution
⚠️

Tartar Control with Baking Soda and Peroxide

Colgate

This conventional paste utilizes sodium lauryl sulfate (SLS), a harsh synthetic detergent clinically linked to an increased risk of aphthous ulcers (canker sores). It also relies on artificial dyes like Blue 1 to achieve its visual appeal.

Use Caution
⚠️

Advance White Extreme Whitening

Arm & Hammer

Despite the naturally low abrasivity of baking soda (RDA 7), the added silica in this 'extreme whitening' formula pushes its total RDA to 106. This places it in the highly abrasive category, which can gradually wear down enamel with twice-daily use.

Use Caution
⚠️

Regular Toothpaste

Crest

A 2025 investigation of 51 popular toothpaste brands found detectable lead in this standard Crest formulation. The widespread presence of heavy metals even in mainstream, non-clay formulas points to systemic issues with mineral ingredient sourcing.
