Our mouths play the role of host to quite a few bacteria – hundreds of millions to be exact. In fact, if you've ever had a cavity, or even swollen and bleeding gums, you can blame those guys. With that said, if you wear a removable appliance like a retainer or mouth guard, it's definitely not enough to give it a quick rinse or brush it with a little toothpaste and call it "clean". The Clean Case UV Dental Sanitizer is a uniquely designed portable case that effectively cleans dentures, retainers, mouth and night guards, whitening trays, and other dental devices in just 10 minutes. Using germicidal ultraviolet light, the Clean Case UV Dental Sanitizer kills 99.9% of microorganisms, mold, fungi, and bacteria.
