Your Child's Toothbrush Sheds 2.3 Million Microplastic Particles Into Their Mouth Every Year
A new study found that plastic toothbrushes shed 3,000 microplastic particles per use directly into the mouth. For children, whose gums are thinner and 10x more absorbent than skin, the exposure is even more dangerous.

Their Child's Toothbrush Is Shedding 3,000 Microplastic Particles Per Use Into Their Mouth
Friction between nylon bristles and teeth sheds 3,000 microplastic particles per brush. That's 6,000 per day and 2.3 million per year. These particles enter your child's body through their gums, which absorb 10 times faster than skin.
PUBLISHED SCIENCE: A 2024 study confirmed plastic toothbrushes shed approximately 3,000 microplastic particles per use into the oral cavity. These particles include nylon-6 and nylon-6,6 fibers that break off through mechanical friction during brushing. (PMID: 40680448)

Those Microplastics Carry Hormone-Disrupting Chemicals Straight Into Your Child's Body
Those microplastics carry BPA, phthalates, and PFAS directly into your child's mouth. These are classified endocrine disruptors linked to hormone disruption, early puberty, and reproductive damage. Your child absorbs them through their gums twice a day.
THE SCIENCE: BPA exposure has been linked to a 39% reduction in testosterone levels. Phthalates are classified as endocrine disruptors linked to early puberty and reproductive damage. Microplastics have been classified as obesogens, chemicals that promote fat storage and metabolic disruption, particularly dangerous during childhood development.
WITH PRIMALS KIDS HORSE BRISTLE TOOTHBRUSH:
-
Zero Chemical Exposure No BPA, no phthalates, no PFAS. Natural horse bristle contains none of these chemicals because it was never made from petroleum
-
Protect Their Hormonal Development Your child's endocrine system is still forming. Every chemical exposure during this window has an outsized impact on their growth
-
Nothing Synthetic Touching Their Mouth Every material is natural. Horse bristle and bamboo. That's it. Nothing else
Their Brain, Immune System, and Hormones Are Still Under Construction
Children's brains, hormones, and immune systems are still forming. Microplastics accumulate in the brain at 7 to 30 times higher concentrations than other organs. Brain levels increased 50% from 2016 to 2024. A developing brain is far more vulnerable.
PUBLISHED SCIENCE: Microplastics accumulate in the human brain at 7 to 30 times higher concentrations than other organs. Brain microplastic levels increased 50% between 2016 and 2024. Dementia brains contain 10 times more microplastics than healthy brains. (Nature Medicine, 2024). Children's blood-brain barriers are more permeable than adults, making them more vulnerable to neurotoxic contamination.
WITH PRIMALS KIDS HORSE BRISTLE TOOTHBRUSH:
-
Protect Their Developing Brain Zero microplastics means zero plastic reaching their brain during the most critical years of neural development
-
Shield Their Immune System Their immune system is still learning what to fight. Don't add synthetic chemicals to the list of things their body has to process
-
Give Their Body a Clean Start The toothbrush you choose today shapes their toxic load for decades. Start clean. Stay clean
You Already Switched to Bamboo. The Bristles Are Still Plastic.
You switched to bamboo but the bristles are still nylon. Still shedding microplastics. "Castor oil" bristles are still synthetic polymers. And 76% of bamboo toothbrushes tested positive for Candida fungus within 48 hours. You only solved half the problem.
THE DATA: 76% of bamboo toothbrushes tested positive for Candida contamination with mold onset within 48 hours. "Castor oil" and "plant-based" bristles are still nylon-based synthetic polymers that shed microplastics identical to conventional plastic bristles. The green label doesn't change the chemistry.

Moms Who Made The Switch.
And Never Looked Back.
"I had no idea plastic toothbrushes were shedding microplastics into my son's mouth. Once I learned about it I couldn't unsee it. Switched the whole family to PRIMALS. The horse bristles are noticeably softer than nylon and my son with sensitive gums finally stopped complaining at brush time."
"We tried bamboo toothbrushes before but the bristles were still nylon. PRIMALS is the first one where everything is actually natural. My daughter's dentist even commented on how clean her teeth were at her last visit."
"The standing design is a game changer. Our old bamboo brushes would get green spots within weeks because they sat flat on the counter. These stand upright, dry properly, and my kids don't fight me at brushing time anymore. Worth every penny."
⚠️ Every brush = 3,000 more microplastics in their developing body

Questions? We Have Answers.
When nylon bristles press against teeth, the mechanical friction creates microscopic fragments of plastic that break off. A 2024 study found approximately 3,000 microplastic particles per brushing session are released into the mouth. Over a year, that adds up to more than 2.3 million particles entering your child's body through their gums.
Yes. Horse bristle is the softest natural bristle option available for toothbrushes. The strands are finer and more flexible than boar (which is firmer by nature) and softer than the synthetic nylon used in conventional kids' brushes. Horse hair has been the premium choice for delicate hairbrushes and makeup brushes for centuries because of how gentle each strand is. The same property makes it ideal for sensitive gums, smaller mouths, and beginner brushers who don't always control their pressure.
The bristles are humanely collected from the manes and tails of working horses, harvested as a byproduct of routine grooming and trimming. No animal is harmed in the collection. Horse hair grows back continuously, so this is sustainable and renewable. We choose this source because the alternative is petroleum-based plastic that ends up in your child's bloodstream and the ocean. The hair is thoroughly washed, sanitized, and trimmed to the appropriate length before being set into the bamboo handle.
Yes. PRIMALS offers a Kids Boar Bristle Toothbrush for older kids and stronger brushers who want a firmer, deeper clean. Boar bristle is naturally firm but not harsh, providing thorough plaque removal without the abrasive micro-scratches of nylon. Same zero-plastic, zero-glue design that stands on its own and dries properly. Both options share the bamboo handle and 100% plastic-free promise.
No. The PRIMALS Kids Toothbrush is designed to stand on its own so it dries properly between uses. The bottom of the handle is coated with non-toxic paint to prevent mold growth. Unlike most bamboo toothbrushes that sit flat in wet environments, ours stays upright and dry.
Ages 3 and up. The handle is sized specifically for small hands, making it easy for children to grip and maneuver during brushing. We recommend swapping the toothbrush every 2 to 3 months for optimal hygiene.
