My teeth are super sensitive so I have had a hard time using mainstream whitening products. That was until I found these sensitive whitening strips from Crest.
They are wonderful! They pack the same punch as the Crest 3D whitening stips, but with very minimal sensitivity. I have only used 4 strips and am already noticing a difference. You can keep these on for up to an hour for faster results. The price tag is also very attractive. Right now on Amazon.com you can get 56 strips for $29.99! I highly recommend giving these a try.
