The Short Answer
Hello Kids Toothpaste is a massive step up from conventional brands like Crest or Colgate. They successfully eliminated the worst offenders in children's oral care, replacing harsh SLS and artificial dyes with gentle surfactants and natural sweeteners.
However, recent independent testing found concerning levels of lead and mercury in their popular Watermelon fluoride-free formula. Between the heavy metal lawsuits surfacing in 2025 and confusing brand messaging around their use of titanium dioxide, we recommend proceeding with caution. Safest Kids Toothpaste
Why This Matters
Kids are notorious for treating toothpaste like a snack. Because toddlers routinely swallow their toothpaste, ingredient purity is non-negotiable. The FDA doesn't strictly regulate heavy metals in cosmetics, meaning parents have to act as their own quality control. Is Swallowing Toothpaste Dangerous
The brand's acquisition changed its trajectory. Colgate-Palmolive quietly bought Hello Products in 2020, taking it from an indie darling to a corporate subsidiary. Is Colgate Safe While the formulas initially stayed the same, mass production under a mega-corporation often introduces supply chain vulnerabilities.
Natural doesn't always mean safe. Ingredients sourced from the earth can carry heavy metals if the soil is contaminated. When a brand fails to rigorously test their raw materials, elements like lead and arsenic can easily slip into the final product.
What's Actually In Hello Kids Toothpaste
- Sodium Fluoride — The active cavity-fighter in their non-training toothpastes. While effective, it carries risks of dental fluorosis and systemic toxicity if your child swallows too much. Should Kids Use Fluoride Toothpaste
- Titanium Dioxide — Used purely to make the paste look bright white. Hello claims on their FAQ to be free of it, yet it's actively listed on several of their ingredient labels. Is Titanium Dioxide In Toothpaste Safe
- Xylitol & Erythritol — These natural sugar alcohols are oral care superheroes. They actively starve the bacteria that cause plaque and cavities.
- Sorbitol — A safe humectant that keeps the paste from drying out. However, it is currently the center of a class-action lawsuit claiming Hello falsely markets it as a non-artificial sweetener.
- Cocamidopropyl Betaine & Sodium Cocoyl Glutamate — Gentle, coconut-derived alternatives to harsh sulfates. These create a satisfying foam without causing canker sores or stripping the oral microbiome. What Toothpaste Has No Sls
- Natural Flavor — A frustrating catch-all term. Because they don't disclose the exact flavor compounds, the EWG bumps their hazard score to a moderate 3.
What to Look For
Green Flags:
- No SLS — They skip sodium lauryl sulfate entirely, relying on gentler cleansers that won't irritate sensitive toddler gums. Is Sls In Toothpaste Bad
- No Artificial Dyes — You won't find Red 40 or Blue 1 here, ensuring your kid's oral care routine isn't contributing to synthetic dye exposure.
- Xylitol Inclusion — Using xylitol is a massive win for cavity prevention, especially in their fluoride-free formulas.
Red Flags:
- Heavy Metal Contamination — Independent 2025 lab tests found lead, mercury, and arsenic in the fluoride-free watermelon flavor, sparking intense concern among parents.
- Titanium Dioxide — This whitening agent is banned as a food additive in the EU due to DNA damage concerns, yet Hello still uses it in several kids' formulas.
- Lack of Transparency — Hiding behind "natural flavor" prevents parents from knowing exactly what their kids are consuming.

2. Watch out for heavy metals. If you currently use Hello, you may want to pause until the 2025 lead and mercury lawsuits are resolved and the brand shares updated purity tests.
3. Check the label for titanium dioxide. Avoid pastes that rely on this unnecessary cosmetic whitener, especially for children who swallow their toothpaste.
FAQ
Does Hello Kids Toothpaste have fluoride?
They offer both. Hello makes specific fluoride versions containing 0.24% Sodium Fluoride, as well as fluoride-free alternatives sweetened with xylitol. You have to read the packaging carefully to ensure you're buying the right one.
Is Hello Kids Toothpaste EWG Verified?
No, they are not EWG Verified. Their kids' toothpastes generally score between a 2 and 3 (Low to Moderate Hazard) on the EWG Skin Deep database. The main factor dragging down their score is the undisclosed "natural flavor" ingredient.
Did Colgate buy Hello Toothpaste?
Yes, Colgate-Palmolive acquired Hello Products in early 2020. While the brand still operates semi-independently with its original branding, it is now fully owned by one of the largest personal care conglomerates in the world.
