EverSmile WhiteFoam Cleans aligners with no need to rinse, brush or soak. It prevents stains on aligners, freshens breath, and whitens teeth. Portable and easy to use WhiteFoam can be used in the morning, at night, between meals, or while you’re on the go. Simply remove your aligner, add a half pump of foam directly to the tray, and pop it right back in with no need to rinse, brush or soak. While the foam gets to work, patients can get back to their busy day.
