Professional Dental Hygiene, Now Built for Your Home
Hospital-Grade UV Sterilization
RetainFresh targets pathogens with precision 254nm UV light, wiping out 99.99% of harmful bacteria on contact. Your appliances come out not just clean — but clinically sanitized.
42,000 Hz Deep-Clean Waves
Ultrasonic vibrations generate microscopic cleaning bubbles that reach into every groove and crevice your brush can't touch. Stubborn stains and hidden debris simply don't stand a chance.
5-Minute Hands-Free Cycle
A full sterilization and deep-clean cycle completes in just five minutes — with automatic shut-off when it's done. Fits seamlessly into even the most packed morning routine.
Universal Appliance Compatibility
Designed to work safely with retainers, clear aligners, mouthguards, and full dentures. One device covers every appliance in your household without risk of damage.

Based On Real and Honest Experiences
I've been dealing with persistent odor on my retainer for months despite regular brushing. Two weeks with RetainFresh and the difference is night and day — it smells fresh, looks clear, and I actually feel confident wearing it again. This thing genuinely changed my routine.
As someone who wears a mouthguard every night, keeping it clean has always been a chore. RetainFresh handles the whole job in 5 minutes while I'm making coffee. The UV sterilization gives me real peace of mind knowing it's not just visually clean but actually sanitized.
I'll be honest — I thought a gadget this small couldn't do much. I was wrong. RetainFresh cleaned staining off my aligners that weeks of soaking tablets never touched. I now recommend it to everyone in my Invisalign group. Skeptic officially converted.
