2025 Research — New England Journal of Medicine

Your plastic toothbrush sheds microplastics directly into your gums — twice a day.

The average plastic toothbrush releases 2.3 million microplastics into your body per year. Scientists just found them inside human arteries. We made the one that doesn't.

What's actually going into your body every morning

Most people obsess over diet, filtered water, and organic food — then pick up a petroleum-derived nylon brush twice a day.

ScienceDirect · 2025

Plastic bristles shed particles directly into your gum tissue

39 microplastic fragments per session enter the gingival tissue and bloodstream pathways.

Regulators now classify microplastics as a health risk

Global restrictions are increasing — but toothbrush brands haven't changed.

Not all "natural" toothbrushes are equal

Most bamboo toothbrushes still use nylon bristles — meaning they're plastic where it counts most.

Boar and horse hair are natural keratin fibers — the same protein as your own hair and nails. They flex. They clean. They biodegrade. And they shed zero synthetic polymer fragments.

🌿
Step 01

Natural Keratin Bristles

Boar or horse hair is pure protein — no nylon, no polypropylene, no PFAS coatings. Under a microscope, they look nothing like plastic bristles. Under any test, they release nothing synthetic.

🎋
Step 02

Sustainable Bamboo Handle

Grown from a single piece of sustainably-sourced bamboo. No plasticizers, no synthetic coatings. It feels dense, premium, and real — because it is. Sealed with a non-toxic base to resist moisture and mould.

♻️
Step 03

Fully Biodegrades

When it's done, it goes back to the earth — not to a landfill for 500 years. No microplastic residue. No synthetic fibers in the ocean. Just a toothbrush that existed and then disappeared the way nature intended.

What people are saying

★★★★★

"I've been trying to reduce microplastics for a while — filtered water, glass containers, organic food. Then I saw the research on toothbrushes and had a lightbulb moment. Made the switch immediately. The boar bristle feels firm but not harsh."

Sarah M. — Melbourne
Boar Bristle
★★★★★

"My naturopath recommended switching during our TTC journey. I didn't think a toothbrush could matter but the research convinced me. The horse hair is incredibly soft — my gums have never felt better. Two months in."

Jess T. — Brisbane
Horse Hair
★★★★★

"My partner works in cardiology. When I sent him the NEJM study he immediately switched. We both use the boar bristle now. Feels premium, cleans well, and we feel good about not adding to our microplastic load every day."

Frequently asked

Do boar and horse hair bristles actually clean properly?

Yes — natural bristle toothbrushes have been used for centuries and are highly effective at plaque removal. Boar hair is firm and ideal for thorough cleaning. Horse hair is softer and excellent for sensitive gums and gum lines. Neither require any synthetic additives to perform.

Are the bristles sterilized?

Yes. All Toxin 3 bristles are 100% pure sterilized animal hair. The handle's self-standing base and non-toxic sealer also prevent moisture and bacterial buildup between uses.

Where does Toxin 3 deliver?

We deliver Australia-wide, with free shipping on orders over $50. International shipping is available — contact us for rates and delivery times to your country.

What is the TTC protocol and why does it matter?

TTC (Trying to Conceive) protocols often recommend eliminating sources of endocrine-disrupting chemicals and synthetic polymers. Standard toothbrush bristles are made of nylon — a plastic with documented endocrine-disrupting additives. Toxin 3's all-natural bristles contain no synthetic polymers, making them the recommended choice for those following TTC or hormone-sensitive health protocols.

What makes Toxin 3 different from other bamboo toothbrushes?

Most "eco" bamboo toothbrushes still use nylon bristles — which means they're plastic where it matters most. The bristle is the only part that contacts your gums and teeth. Toxin 3 uses boar or horse hair b
