The Best Ultrasonic Retainer Cleaners That Keep Trays Shiny And Bacteria-Free


You brush your teeth, floss regularly and faithfully wear your retainer every night. But despite your diligent oral health habits, your retainer or mouth guard can get yellowed, cloudy or stained. Translation: Your oral care device is pressed up against your teeth for hours every night, exposing it to bacteria. The best ultrasonic retainer cleaners (like the Souncrise Dental Pod, our top pick) remove stains and films, sanitize, are easy to use, and look good in your bathroom.

“A retainer accumulates plaque, bacteria and biofilm just like natural teeth does,” says Dr. Pia Lieb, founder of Cosmetic Dentistry Center NYC. “If not cleaned properly, it can lead to persistent bad breath, gum inflammation, fungal infections and even tooth decay.” Ultrasonic retainer cleaners use high-frequency sound waves to create microscopic vibrations and bubbles in water, effectively dislodging bacteria, debris and buildup. When purchasing, look for a high vibration frequency for better cleaning, quiet operation, a tank size that accommodates your appliance and helpful features like an auto-shutoff. Whether you have an aligner, night guard or complex retainer, we found the best ultrasonic retainer cleaners to deep-clean your dental appliance.

After having braces twice, I wanted an effective, reliable cleaner that would keep my Invisalign aligners sparkling but also look nice in my bathroom. The Souncrise Dental Pod uses high-frequency 48,000 kilohertz (kHz) ultrasonic waves to dislodge gunk like plaque and stains from the nooks and crannies. How it works: You fill the container with water, put on the lid and press a single button before it automatically shuts off five minutes later. Plus, the slim profile and sleek silhouette—it comes in four colors—make it good looking enough that you can leave it out on your bathroom counter all year long. I’ve owned this device for more than a year and use it religiously. My husband has the Souncrise Dental Pod, which is slightly roomier since he has a bigger night guard, and he loves his as well.
