Extensive clinical and consumer testing was done to establish the safety and efficacy of Crest 3D White Whitestrips. However, based on the results of that work we do not recommend using more than 2 upper strips and 2 lower strips in a day. Limit use to just 5 minutes a day. Longer wear time can result in tooth sensitivity. If you are looking for faster whitening results, please try Crest 3D White Whitestrips Classic Vivid , It is formulated to be worn for 30 minutes daily and provide results in only 10 days.
