Join thousands who ditched plastic for good

No plastic in my routine

Brushing synthetic bristles across my teeth twice a day never sat right with me. Real horse bristle means nothing plastic in my mouth.

ANDRE K.

Natural down to the handle

Wanted a brush with no plastic anywhere in it. Bamboo and soft horse bristle is the whole thing, so that's exactly what I got.

MARISA T.

Nothing synthetic touching my teeth

Cutting plastic out of my body wherever I could was the goal. The brush I use every day felt like the right place to begin.

JONAH P.

Dries upright, stays fresh

My old brush sat damp in a cup and got grimy. This one stands on its own base, so it air-dries and never stays wet between uses.

CLARA H.

No pooled water, no funk

Love that it dries standing up instead of face-down in a holder. Nothing collects on it, so it looks and smells clean every day.

FELIX V.

Clean handle, every time

Old brushes built up gunk where they rested. This one dries out fully on its stand, so there's nowhere for anything to grow.

IMANI B.

No glued-in tufts

Most brushes set the bristles in glue that wears down and traps residue. These are woven in without any, which is what won me over.

SOPHIE S.

Stayed intact, no shedding

Cheap brushes drop bristles once the adhesive fails. Woven with no glue, so mine has held together the whole time I've used it.

TOBIAS A.

Clean construction, no glue

No glue wells, no filler, just bristles woven into the bamboo. One less thing sitting in my mouth that I have to wonder about.

LUCIA G.

My gums finally stopped hurting

Brushing used to leave my gums sore every time. A week into the soft horse bristle and that tenderness was just gone.

NINA L.

Soft but still gets everything

I've got sensitive gums and most brushes feel rough. This one is gentle and my mouth still feels properly clean afterward.

DESMOND H.

Kind on a receding gumline

My gums had started pulling back and firmer brushes made it worse. Soft horse bristle cleans without that scraping feeling.

YARA N.

Microplastics released from a toothbrush
The problem

The hidden cost of brushing

Your toothbrush releases 2.3 million microplastics every year

Every brush session releases thousands of invisible plastic particles straight into your mouth. Nylon bristles break down under friction, and the fragments end up somewhere they were never meant to go.

  • Plastic bristles shed with every brush stroke
  • Nylon bristles are made from petroleum
  • That's 3,192 particles per brush session
  • BPA and phthalates hidden inside every bristle
Microplastic particles absorbing through gum tissue
The mechanism

How it gets inside your body

You are not swallowing it. You are absorbing it.

Gum tissue is among the most permeable in your body. Microplastics do not need to be swallowed to reach you. They absorb straight through the gums into your bloodstream.

  • Friction breaks bristles into invisible toxic fragments
  • Gums absorb directly, no swallowing required
  • Gum tissue is among your body's most permeable
  • Particles found in blood, brain and gut

The effects

What it does once inside

Microplastics don't leave. They build up and damage.

BPA and phthalates from nylon bristles disrupt hormones, drive inflammation and accumulate in vital organs. Your body has no way to break these compounds down, so exposure compounds over years.

  • Disrupts hormone balance and testosterone levels
  • Triggers chronic inflammation throughout the body
  • Associated with fatigue, brain fog and infertility
  • Linked to gut damage and digestive issues

US VS THEM

Not every toothbrush marketed as safe or healthy actually delivers on that promise.
