How RetainFresh Is Built and Used

Ultrasonic Cleaning Action

The unit sends ultrasonic waves through a water-filled tank. The waves form tiny bubbles around the appliance, including in grooves and small surfaces where a brush has limited access.

Built-In UV LEDs

UV LEDs with a 254 nm wavelength sit inside the unit and run during the same cycle as the ultrasonic waves. The cycle uses water and light only.

RetainFresh

Single Button and Auto Shut-Off

One button starts the cycle. The unit switches itself off when the cycle ends, so you can start it during your morning or evening routine and return to it afterward.

Appliance Compatibility

RetainFresh is made for retainers, clear aligners, mouthguards and full dentures. One unit can be used for any of these appliances, whichever ones your household wears.
