The clear retainer in your mouth isn't as clean as it looks.
Traditional retainers are made from PETG, a petroleum-based plastic. The Unplastic retainer is made from PHA, a biopolymer grown by microbes. Watch what happens to each over time.
0nights of wear
Standard (PETG)
Sheds persistent microplastic flakes that stick around in your body.

Particles Accumulate
Unplastic
Particles break down into a molecule your body already produces (3-hydroxybutyric acid)

Particles Break Down

The average retainer persists in your body.

Worn 6-8 hours a night, for years.

Heat, moisture, and abrasion break plastic down over time.

Anything that doesn't manage to get out accumulates forever.
The solution
The
retainer is made from PHA, grown by microbes and broken down safely by your body.
- Grown by microbes, not refined from petroleum
- Breaks down into a molecule your body already makes
- Third-party tested for contaminants
Grown through fermentation
