Our story

How we started

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. The results of our study were shocking.

Then I looked at the other things I use every day. My toothbrush? My water bottle? Pacifiers? Nobody had checked any of it. I’d already decided microplastics were a problem, but what about everything else that could be in there? The things we use every day should be held to a higher standard than food. None of them were.

What we do

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

What we believe

We’re researchers, designers, and engineers guided by our three principles.

Test everything. Toxins can sneak in at every step of the supply chain. We don’t trust until we verify.

Everything sheds. So we only use materials that break down harmlessly and cannot accumulate.

Better to use, not just better for you. If the swap isn’t painless, nobody will make it.
