Basically, these tooth whitening light products use a blue-light turned on gel of 35% Cross Carbamide Peroxide solution. That gel is positioned by you inside a teeth mold, and then clamp down on one’s teeth mildew. Then, you place the light-emitting device against your lips and hold it as the light would go to work.
The blue light is established by LEDs. It responds with the gel to whiten and enhance your pearly whites by rapidly taking away surface discolorations and embedded staining. Ultimately, carbamide peroxide and similar alternatives are available in other pearly whites whitening products often. However, there is no information or studies posted online that White Light Smile could work as advertised (along using its competitors).
