Use the cleaning method approved for the exact retainer, aligner or night guard. Tablets and ultrasonic devices are not universally compatible, so follow the appliance maker or orthodontist instructions before soaking or using a machine.
Cleaning tablets and ultrasonic devices are tools, not universal instructions. Clear aligners, wire retainers, acrylic appliances and night guards can use different materials. Check the appliance maker’s cleaning directions or ask the orthodontist before soaking it, using a tablet or placing it in a powered cleaner.

Invisalign’s FAQ directs users toward lukewarm water and its crystals or special cleaning tablets. Other appliance manufacturers can give different instructions. Do not generalize one brand’s method to all retainers.
Keep the daily routine simple
Rinse the appliance when removed, clean it as directed, and store it in its case. Do not leave it in a napkin or expose it to heat. If the appliance becomes cloudy, cracked, distorted or uncomfortable, ask the orthodontist before continuing to use it.
See how to clean retainers and aligners for the routine, and check the specific manufacturer’s directions before choosing a cleaner. This is appliance-care information, not dental advice.
