Children's toothbrushes come in every color and character. What they almost never come in is something other than nylon — the synthetic plastic that makes up every mainstream bristle on the market.

Every time a child brushes, nylon bristles shed microparticles directly against their gum line and oral tissue. Children's mucosal membranes are particularly absorptive. Their bodies are smaller, which means a given dose of any substance represents a larger proportional exposure. And they're doing it twice a day from the time their first teeth appear.

The Primals Kids Horse Bristle Toothbrush was built specifically for this. The horse hair bristles are 100% natural, among the softest available in natural bristle options — gentle enough for developing gums while still removing plaque effectively. The handle is sized for small hands, made from bamboo with no synthetic coatings or glue. Nothing in this toothbrush contains BPA, phthalates, or PFAS. Nothing about it sheds microplastics.

The switch eliminates an estimated 2.3 million microplastic particles from your child's yearly intake. Given how early the habit starts and how long it continues, that's a meaningful number.

It also biodegrades. Unlike every plastic toothbrush your child would otherwise go through — which will outlast them by centuries — this one doesn't.
