Few brands have disrupted the oral care market quite like Hello Products. With their “naturally friendly” aesthetic, bright packaging, and exotic flavors such as Dragon Dazzle and Blue Raspberry, they’ve managed to transform a mundane task into a lifestyle decision.
However, with recent news stories and a major 2025 class-action lawsuit about heavy metal contamination, consumers have been left wondering: Is Hello toothpaste still safe for my family?
In this detailed 2026 guide, we’ll dissect the science behind the ingredients, evaluate the brand's on-the-ground performance, and take a closer look at the legal troubles currently plaguing the brand.
Hello Toothpaste Ingredients: What’s in the Tube?
Hello’s philosophy revolves around what’s not in the product—no artificial sweeteners, dyes, or SLS. But the health of your enamel is ultimately determined by what they do put in.
Key Active Ingredients
Nano-Hydroxyapatite (nHAp) — Found in their fluoride-free lines. This synthetic form of the same mineral that forms 97% of your tooth enamel works by “plugging” tiny gaps in the teeth to help relieve sensitivity.
Sodium Monofluorophosphate — Included in their “anti-cavity” lines, this is standard, dentist-approved fluoride that strengthens enamel and makes it more resistant to acid attacks.
Activated Charcoal — Featured in their “Epic Whitening” line, this ingredient binds to surface stains to help whiten teeth.
Calcium Carbonate — A mildly abrasive substance that gently scrubs away plaque and surface stains without being too harsh.
The "Natural" Support Team
Coconut Oil — Used for its moisturizing properties and pleasant “mouthfeel.”
Tea Tree Oil — Known for its antimicrobial properties, it helps fight bad breath.
Xylitol & Erythritol — Non-fermentable, plant-based sweeteners that bacteria cannot ferment, helping prevent decay.
Everything You Should Know About the 2025 Lead & Mercury Lawsuit
The largest cloud over the brand is a series of class-action lawsuits filed in late 2025 (e.g., Browne v. Hello Products LLC and Barton v. Colgate-Palmolive).
The Allegations
The civil suits claim that independent laboratory testing found “dangerously high levels” of heavy metals in multiple Hello products, including the Kids’ Fluoride-Free and Unicorn Sparkle lines.
Lead Contamination: The testing showed lead levels between 236 and 658 parts per billion (ppb). For comparison, the FDA limit for lead in candy—a similar edible—is 100 ppb.
Mercury Issues: The filings also mentioned smaller amounts of mercury.
The Defense
In early 2026, Hello’s parent company, Colgate-Palmolive, stated that their products are safe and comply with all relevant regulatory authorities and guidelines for cosmetic oral care.
Know Your Metals
Because heavy metals are naturally found in the earth, they often appear as “trace contaminants.” Since Hello uses natural minerals like clay and calcium carbonate, ultra-pure filtration is a constant challenge for "natural" brands.
Real User Reviews: The Good, The Bad, and The Grimy
Hello has found huge success with its unique brand, but reviews are divided between fans of the “natural” feel and users who miss a more “traditional” clean.
✅ The Pros (What Users Love)
Kid-Approved Flavors: Parents love that kids who once complained about brushing now enjoy flavors like “Dragon Dazzle” or “Watermelon.”
No “Canker Sores”: Many users with sensitive mouths appreciate the lack of SLS, noticing a significant decrease in painful mouth ulcers.
Ethics: Hello is Leaping Bunny certified (cruelty-free) and vegan.
❌ The Cons (Common Complaints)
The “Yellow” Effect: Some users complain that while the fluoride-free, charcoal-infused paste can remove surface stains, it can’t stop internal yellowing over time, resulting in a “duller” smile.
Endurance for Freshness: While the minty freshness is pleasant at first, it wears off quickly compared to brands like Crest or Colgate.
Tube Design: The thick plastic tube can make it frustrating to get out the last 15% of product.
General Comparison: Hello vs. Traditionals vs. Hismile
| Feature | Hello (Natural) | Traditional (Crest) | Hismile (Cosmetic) |
|---|---|---|---|
| Whitening | Charcoal/Abrasives | Peroxide | PAP+ (Non-peroxide) |
| Foaming | Low (SLS-Free) | High (Contains SLS) | Moderate |
| Key Mineral | Hydroxyapatite or Fluoride | Fluoride | Hydroxyapatite |
Is Hello "Dentist Approved"?
The short answer is yes, but with caveats.
Several Hello products, including Hello Kid’s Fluoride Toothpaste, bear the ADA Seal of Acceptance. This means that clinical data establishing the product’s safety and effectiveness in preventing cavities has been reviewed by the American Dental Association.
However, dentists typically warn against:
Fluoride-Free for High-Risk Patients: If you or your child has had cavities, switching to a fluoride-free natural paste may result in a “cavity explosion” within 6–12 months.
Charcoal Abrasivity: Some dentists believe the charcoal line is too abrasive to use daily, as it could wear down enamel if you brush too hard.
💡 Takeaways for Consumers in 2026
Check the Label: If you’re concerned about cavities, seek out the “Anticavity” version with fluoride.
Monitor Lawsuit Developments: If you’re using the Kids’ Fluoride-Free or Unicorn Sparkle lines, you might want to keep an eye on the ongoing lawsuit.
Vary Your Paste: Some dental experts recommend using a natural paste during the day and a fluoride-based paste at night for better protection.
❓ Frequently Asked Questions (FAQ)
1. Is Hello toothpaste safe for toddlers?
Hello’s fluoride-free training toothpastes are marketed as “safe if swallowed.” However, due to lead allegations in 2025, many parents are now choosing brands that have third-party “Clean Label” certifications. It’s recommended to wait until the lawsuit is settled before making a final decision.
2. Does Hello toothpaste have fluoride?
Yes! Hello offers both fluoride and fluoride-free options. Be sure to check the “Active Ingredients” on the back of the box to confirm which version you have.
3. What do we know about the Hello toothpaste lawsuit?
The 2025 class-action lawsuit alleges that some batches of Hello kids’ toothpaste contained lead and mercury levels above safety guidelines for products likely to be ingested by children.
4. Does it actually whiten teeth?
Yes, Hello whitens teeth "naturally" by removing surface stains (specifically from coffee, tea, and wine). Unlike peroxide-based whitening gels, it does not bleach the internal structure of the tooth.
5. Is Hello owned by Colgate?
Yes, Hello Products was acquired by Colgate-Palmolive in early 2020. However, it remains its own brand and still operates under its own formulations.
Final Verdict
Hello Toothpaste offers an excellent option for SLS-free, vegan, and pleasant-tasting oral care. The 2025 lawsuit is concerning, but it underscores the need for higher-quality testing when it comes to natural products. If you love the brand, consider using their ADA-approved lines or alternating with a remineralizing paste to balance both safety and the benefits of natural ingredients.
