Why a Child's Toothpaste Is Judged as Food

A toddler swallows toothpaste. A training paste goes down almost entirely, and a six year old still swallows a good share of a pea. That is why the American Academy of Pediatrics and the American Dental Association tell parents to use a smear the size of a grain of rice from the first tooth and a pea from age three, partly for fluorosis and partly because small children cannot reliably spit.

Swallowing turns a cosmetic into a food. A trace of lead in a paste an adult spits out is a passing exposure. The same trace in a paste a two year old swallows twice a day is a daily dose, children absorb a far larger share of the lead they swallow than adults do, and the CDC's position is that no level of lead exposure in a child is known to be safe. So this page holds kids toothpaste to the bars for food eaten by children: 5 ppb lead, 5 cadmium, 2 mercury and 10 arsenic, the action levels proposed in the Baby Food Safety Act of 2021.

What Independent Testing Found

Through 2025 the advocacy project Lead Safe Mama sent toothpastes, one retail unit at a time, to Purity Laboratories in Lake Oswego, Oregon, for ICP mass spectrometry on lead, cadmium, mercury and arsenic, with limits of 5 ppb for the first three and 10 ppb for arsenic. The list, updated in May 2026, holds 69 published products, 39 of them sold for children. Nothing was retested in 2026, so every result on this page stands on its original report.

Thirty five of the 39 kids products carried lead. The readings run from 16.8 ppb at the bottom to 568 ppb in a bubblegum fluoride gel, with two clay powders sold for children in the thousands. Four came back non detect for all four metals: Spry Kids Tooth Gel in the Original flavor, Dr. Brown's baby toothpaste, Orajel's Elmo training paste and a watermelon foam called Pegciz. The products most parents actually buy sit in the middle of the range, between about 130 and 500 ppb.

The pattern in the chemistry is plain once you read the labels side by side. Lead Safe Mama's single ingredient tests put hydroxyapatite at about 269 ppb lead and calcium carbonate at about 292, and her narrative names bentonite clay, hydroxyapatite, calcium carbonate, hydrated silica and titanium dioxide as the ingredients that appear to drive the results. The four clean kids pastes are xylitol and glycerin gels with none of those as a main ingredient. The metals are not a contamination accident. They come in with the minerals.

The Picks

One product clears every check: a non detect lab result, a complete label with nothing on the hazard list, a plastic tube that passes the materials check for a water based paste, and a clean recall and lawsuit search. Two more share its lab result and fall short on one line of the label, so they are here as the honest second choice for a child who refuses an unflavored gel, with the gap stated on the card.

$ · TOP PICK, NON DETECT, EVERY INGREDIENT NAMED

Spry Kids Tooth Gel, Original

Xylitol gel with five named ingredients and no flavor line, sold for use from the first tooth. Non detect for lead, cadmium, mercury and arsenic at Purity Laboratories in March 2025. Fluoride free, plastic tube.

Dr. Brown's Fluoride Free Baby Toothpaste

Xylitol and glycerin paste for babies, non detect for all four metals in March 2025. Careful: its single flavor line reads Aroma/Flavor with no source named, which is the one thing that keeps it from being the pick.

Orajel Kids Training Toothpaste, Elmo

Fluoride free training paste on glycerin and banana extract, non detect for all four metals at SGS North America in February 2025. Careful: its Natural Flavor names nothing, the same gap that holds Dr. Brown's.

Spry Kids Tooth Gel, Original is the pick because it is the only kids paste that is clean on both counts at once. The label reads purified water, xylitol, calcium glycerophosphate, cellulose gum and grapefruit seed extract, and that is the whole of it: no flavor entry, no sweetener beyond the xylitol, no mineral abrasive. The Original flavor is the SKU that was tested, which matters, because the same brand's bubblegum fluoride gel read 568 ppb lead. Buy the plain one.

Dr. Brown's and Orajel's training paste tested exactly as clean, at the same limits, and both are a real option for a baby who will not take an unflavored gel. The trade is written on the card. Each lists its flavor as a bare umbrella term, Aroma/Flavor on one and Natural Flavor on the other, with no source and no components, and a flavor is the one ingredient a paste for an infant should not leave vague. That is a disclosure gap, not a hazard finding, which is why both are careful rather than skip, and why they sit behind Spry rather than beside it.

What Separates the Four Clean Results

Four kids pastes tested non detect and only one is a pick, and the reason is the label. Spry Original names every ingredient. Dr. Brown's and Orajel hide the flavor behind an umbrella word. The fourth, Pegciz, a low fluoride watermelon foam sold through Amazon and Walmart, publishes no ingredient list anywhere, not on the box, not on either listing and not on a website we could find, and the company behind it has no traceable identity. A clean lab result on a product nobody can read the label of is not a recommendation, so it is held at careful and left off the cards.

Two more kids products on Lead Safe Mama's list are still marked pending with no numbers, an Elmex infant paste from France and a product called Vitamin Paste, so neither can be rated yet.

Fluoride for Kids, Honestly

The American Academy of Pediatrics and the American Dental Association advise fluoride toothpaste from the first tooth, in a smear under three and a pea from three to six, and your child's dentist may well say the same. Nothing on this page argues with that advice. The problem is narrower: which fluoride kids paste, given what the lab found.

None of the fluoride kids pastes tested is both non detect and fully labeled. Pegciz is non detect with no label at all. The lowest fluoride reading with a label is Red Seal's kids gel from New Zealand at 41.5 ppb lead with everything else non detect, then Made by Dentists' Cheetah Dust at 79.4. The mainstream fluoride kids pastes read 100 to 568: Orajel's own Paw Patrol anticavity paste at 100, Crest Kids at 132, Colgate's watermelon paste at 302, the fluoride versions from Tom's of Maine and Hello at 421 and 428, and Spry's bubblegum gel at 568.

What that leaves a parent is a dose problem rather than a brand problem. A smear instead of a squeeze cuts the swallowed lead by the same factor it cuts the swallowed fluoride. Fluoride varnish applied at dental visits puts the fluoride on the teeth and not down the throat, and is what the AAP recommends from the first tooth for children at risk of cavities. And for the twice daily brushing in between, a non detect gel is the one choice that adds no lead at all. Ask the dentist about the first two; the third is on the cards above.

The Hydroxyapatite Kids Pastes

Hydroxyapatite is sold to parents as the clean alternative to fluoride, and every hydroxyapatite paste in the round, fourteen products, carries a detection. The kids versions are the best of that class and still fail the bar: the two lowest read 26 and 27 ppb lead, five times the food bar, with mercury, cadmium or arsenic detected beside it, and the rest run from 54 to over 400. The single ingredient test explains why. The hydroxyapatite itself read about 269 ppb lead, so a paste built on it starts with the metal already in the tube.

Products We Did Not Pick

These are the kids pastes parents ask about most. Each reading is lead in parts per billion from Lead Safe Mama's 2025 testing at Purity Laboratories, with the other metals where they were detected, against a bar of 5 ppb.

Every Kids Toothpaste Tested

All 41 children's products with a published result on Lead Safe Mama's May 2026 list, lead first, lowest to highest, in parts per billion. "nd" is non detect at the lab's limit, 5 ppb for lead, cadmium and mercury and 10 ppb for arsenic. Caution means a detection; fail means lead at 500 ppb or more, the line German food safety authorities apply to toothpaste.

How We Checked

Every product here was run through the same four checks the whole site uses: the ingredient list read verbatim from the label or the brand's own page, the material in contact with the paste, the independent lab result, and a search of the FDA enforcement database, the Proposition 65 register and the court dockets, all done on 16 October 2026. The lab numbers are Lead Safe Mama's, read from the laboratory reports on her product posts rather than from a summary, with the case and lot numbers recorded. We ran no tests of our own. Every Amazon listing on this page was opened the same day and was in stock. The full standard every verdict is held to is published in our verdict standard.
