Teeth Whitening Set Simplesmile Teeth Whitening X4 Expert Kit Refill

The Expert Kit is a complete set for effective at-home teeth whitening — quick, easy, and gentle. It includes a 10ml teeth whitening gel for use with mouth trays, which are individually designed for use with hot water.
The gel contains several active ingredients, including PAP, sodium bicarbonate, and coconut sulfate, which together effectively clean and whiten teeth. PAP is an organic ingredient that leads to a high degree of oxidation. Oxidation is necessary for the whitening process, as it neutralizes organic bonds that cause tooth discoloration.
The Expert Kit teeth whitening gel is 100% peroxide-free, causing no irritation or other unpleasant side effects on teeth or gums.
