Medical-grade PHA
Custom-fit from your existing dental scan and grown through microbial fermentation, not refined from oil. Designed to avoid the persistent microplastics that standard PETG retainers shed in your mouth every night. Third-party tested at body temperature against PETG, and screened for BPA, phthalates, heavy metals, and PFAS.
Ships within five business days of receiving your scan.
$585.00
$-185.00 offSubscribers get free replacements for broken or lost retainers.
We retrieve your dental scan from your practitioner. If we can't retrieve it, we set up an appointment with a scanning partner near you at no extra cost.
Every retainer comes with a 30 day fit guarantee. We fix and replace retainers that don't fit right in the first month of delivery.
Made of pure PHA, and nothing else. We test every batch of material for contaminants, additives, and degradation. Learn more about our materials and testing here.
Our retainers are designed to break down after six months of wear. We recommend a subscription so a new retainer arrives before your current one wears out.
Is the price for an upper and lower?
Yes. The listed price is for the pair.
How do I clean my retainer?
The same way you’d clean any retainer. Just avoid soaking it in water for more than six hours, and keep it away from very hot water.
Why isn’t the retainer perfectly clear?
Making plastic crystal-clear requires adding chemical clarifiers and stabilizers. We leave them out. The slight translucence is the material in its natural state.
