Crest 3d whitening strips made my teeth amazing, but also sensitive. The stuff tastes gross. Follow the directions. I think it was like… Dry your teeth, put the strip on for like 30 minutes (which sucks ass) and then rinse your mouth. Took a few weeks for me to notice and I stopped using them as my teeth looked fine.
