I kept brushing my retainer every day and it still had that white film and smell by day five. A week into using RetainFresh and my only complaint is that I did not get one sooner — it comes out crystal clear every single morning.

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.

I wear a night guard every night and used to scrub it every morning — it never felt truly clean. Three years of daily use and RetainFresh still works perfectly, keeps the guard spotless, and it's quiet enough to run while I get ready. Compact enough to travel with too.

Frequently Asked Questions

+212 expertsreviewed it

Brushing misses biofilm in micro-scratches — that's what clouds trays by day five. RetainFresh cavitation implodes inside every groove, blasting loose film and odor your brush can't reach.

Daily use is ideal. Running a cycle each morning takes only 5 minutes and prevents bacteria from accumulating on your appliances overnight, keeping your oral hygiene consistently at its best.

Plain water works fine on its own. That said, pairing RetainFresh with dental cleaning tablets can boost results even further — especially for appliances with heavier buildup or persistent odors.

Cheap units with thin plastic and weak transducers fail within months. RetainFresh uses proper sealing and a calibrated transducer built for daily home use — real users running quality ultrasonic pods report one to three years of reliable use.

Not at all. The ultrasonic frequency and UV intensity are precisely tuned to break down bacteria and debris without affecting the structural integrity or surface finish of your appliances.

Absolutely. Its compact footprint fits easily in a toiletry bag, and it charges via a standard USB cable — so you can keep your hygiene routine on track whether you're at a hotel or on the road.

Film and odor come from biofilm in micro-scratches your brush can't reach. RetainFresh cavitation implodes in those grooves while UV neutralizes bacteria — users report trays staying clear through day ten of a fourteen-day cycle.

Yes. Dental professionals regularly advocate for ultrasonic and UV cleaning because it removes what manual scrubbing misses. RetainFresh brings that same professional-level standard directly to your countertop.
