Our take on the M3 Naturals Retainer and Denture Cleansers 240 Tablets

M3 Naturals Retainer and Denture Cleansers are effervescent mint tablets that dissolve in warm water to lift stains, plaque and odor from retainers, dentures, night guards and clear aligners. Each tablet is individually wrapped, and a soak of 15 to 30 minutes in one cup of warm water is enough. They are marketed as cruelty free and claim to kill 99% of odor-causing bacteria. They compete with Efferdent, Polident and Retainer Brite on convenience and price per tablet rather than on any unique cleaning technology, and the large tablet count makes them a long-lasting pick for daily users.
