The caps are made based on the shape of your teeth. This feature allows us to approach each client individually, which guarantees the best effectiveness and comfort. The teeth whitening process is repeated until a satisfactory degree of whitening is achieved, from about 1 to 4 weeks. We can whiten teeth during the day, at work or at home, and while sleeping. Thanks to the transparent material, they are virtually invisible. Once purchased, the overlays can last for up to a dozen years.
