Everything that touches your body every day, held to a higher standard than food.

In early 2025 I noticed my retainer was full of cracks and holes.

Where did the missing material go? Was I swallowing it? As someone with a stainless steel and glass kitchen, this freaked me out.

My orthodontist, Dr. Weeman, and I looked for a retainer that wouldn’t leave plastic in my body. There wasn’t one. So I started working with Andrea, our lead scientist, on developing an alternative. We also set out to measure exactly how many microplastics I was eating.

Wearing a retainer doubles the microplastics you eat. What else don’t we know?

We get curious about anything that touches your body a lot.

Toothbrushes. Water bottles. Pacifiers. They all pass a standard. The standard is just too low. So we test them ourselves for contaminants, leachables, and microplastics, and we publish what we find. If it’s bad enough, we start working on an alternative.

Sometimes that means a new material, sometimes a new design. Sometimes it means telling you what you have is fine.

Our standard requires a little paranoia.

Assume contamination.

Toxins get in at every step of the supply chain. We test everything and trust nothing until we verify it.

Everything sheds.

We only use materials that break down harmlessly and cannot accumulate.

Bad products don’t get used.

Nobody switches to something worse. Better for you has to also be better to use.
