They Found Out Their Kid's Toothbrush Was Shedding 3,000 Microplastics Per Brush
A 2025 study found nylon toothbrushes release 3,000 plastic particles per use. That's 6,000 a day and 2.3 million a year into your child's mouth. Children's gums absorb these 10x faster than skin. Microplastics have been found in brain tissue at 7 to 30 times higher levels than 2016.
PUBLISHED SCIENCE: A 2025 study confirmed standard nylon toothbrushes shed approximately 3,000 microplastic particles per use. Combined with a child's significantly higher gum permeability, this delivers particles directly into developing tissue. (PMID:40680448)

They Discovered Their Kid's "Fun" Branded Toothbrush Was a Chemical Cocktail
Cartoon characters, glitter handles, bright colors. The materials tell a different story: polypropylene with synthetic dyes, trace lead and cadmium in paint, BPA and phthalate plasticizers classified as endocrine disruptors. Your kid chews the bristles and swallows whatever leaches off.
THE SCIENCE: Phthalates are linked to early puberty in girls and reduced testosterone in boys. BPA mimics estrogen and disrupts hormone signaling during critical developmental windows. Children absorb at higher rates due to thinner tissue. (J Endocrinol Metab, 2019)
WITH PRIMALS KIDS TOOTHBRUSH:
- Zero BPA, BPS, or PhthalatesNo plastic handle means no plasticizers, no endocrine disruptors in your child's developing body
- Only Non-Toxic, Food-Safe PaintA small color band at the base for multi-kid households. Food-safe pigments, no lead, cadmium, or synthetic dyes.
- Toxin-Free, PeriodThe same standard you apply to their food, water, and skincare. Now applied to the tool in their mouth twice a day.
They Found The Softest Natural Bristle Without Touching Plastic
Every "soft" kids' toothbrush bristle is nylon. Horse bristle is the gentlest natural option most parents don't know exists. Finer and more flexible than boar, genuinely softer than nylon, 100% natural protein. Perfect for sensitive gums, smaller mouths, and kids still developing their brushing technique.
BRISTLE SOFTNESS: From softest to firmest: Horse hair, Boar hair, everything else is synthetic. Horse hair has been used for premium brushes for centuries because of how gentle each strand is. Same property that makes it ideal for delicate hair makes it ideal for delicate gums.
WITH PRIMALS KIDS HORSE BRISTLE:
- The Softest Natural Bristle AvailableGenuinely softer than nylon and boar. The gentlest option for delicate gums and beginner brushers.
- Natural Protein, Not PetroleumReal horse hair is the same biological material as human hair. Natural materials for natural mouths.
- Forgiving for Beginner BrushersKids press too hard. Horse bristle flexes under pressure instead of digging in. Beginner mistakes don't cause damage.
They Switched to Bamboo and Horse Bristle Because Nature Already Solved This
Bamboo has natural antimicrobial properties from bamboo kun, resisting bacterial buildup that turns plastic brushes into microbial farms (10 to 12 million bacteria on a used brush). Horse bristles clean gently without scraping enamel. Used in premium brushes for centuries. We just put it in a size built for kids.
ANCIENT WISDOM: Natural bristle toothbrushes were the standard for centuries before nylon replaced them in 1938. Bamboo handles have been used in Asia for over 1,000 years thanks to bamboo kun. Modern science is confirming what tradition already knew.
WITH PRIMALS KIDS HORSE BRISTLE:
- Naturally Antimicrobial BambooBamboo kun resists bacterial growth. The brush doesn't become a science experiment between uses.
- Fine, Flexible Horse BristlesNatural structure cleans teeth gently and effectively. Flexes with the contours of small mouths.
- Zero Glue. Hand Woven Bristles.No industrial adhesives dissolving into your child's saliva. Bristles are secured directly into the bamboo head.
- Biodegradable End-of-LifeHandle composts, bristles break down. No plastic going to landfill or the ocean.
They Realized The "Bamboo" Toothbrush At Whole Foods Still Had Plastic Bristles
Most bamboo toothbrushes still use nylon bristles, shedding the same microplastics as conventional brushes. On top of that, 76% of bamboo toothbrushes tested positive for Candida fungus within 48 hours because most sit flat on wet counters. Half the swap. Double the problem.
INDUSTRY DECEPTION: The vast majority of "bamboo" toothbrushes use nylon bristles despite green packaging. 76% tested positive for Candida contamination with mold onset within 48 hours. The bamboo handle is an aesthetic upgrade, not a health one.
WITH PRIMALS KIDS TOOTHBRUSH:
- Natural From Handle to BristleBamboo handle plus actual horse bristle. The whole brush is natural, not just the part you can see.
- No Hidden Nylon BristlesThe bristle is the part that touches the mouth. Ours is natural protein, not petroleum.
