The problem with your retainer
You eat plastic in your sleep.
For 8 hours every night, for years, your retainer sits in your mouth under heat, saliva, and bite pressure. Standard PETG retainers shed microplastics straight into your body the entire time you sleep.

Why retainers are different
Warm. Wet. Chewed on.
Your retainer doesn't sit on a shelf. Heat, moisture, and abrasion are exactly the conditions that accelerate plastic degradation. Your retainer experiences all three, inside your body, for a third of your life.
PHA grown by microbes, not petroleum-based plastic.
moses is grown through microbial fermentation. Standard clear retainers are made from PETG, a petroleum-derived plastic originally engineered for food packaging. It was never designed with nightly ingestion in mind.
When it sheds, where does it go?
The particles your retainer sheds under wear are persistent, they build up in the body rather than clearing out the way food does.
The solution
Made from PHA grown by microbes, not petroleum-based plastic. Same custom fit, without the conventional plastic tray.
- Grown through microbial fermentation
- Designed to break down into a body-made molecule
- Actually biodegradable, not just “bio”
Grown through fermentation.
