Review on 🦷 Crest 3D Whitestrips Sensitive Teeth Whitening Kit: Gentle and Effective 14-Treatment Solution by Dana Johnson

I have been using Crest White Strips for sensitive teeth for many years and love them. They have visibly discolored my teeth and as I have very sensitive teeth/gums I really appreciate that they are not bothersome. However, this last twist on the gentle routine of white stripes with extra glue is useless to me. They were very expensive (I paid $67 for 28 treatments of Revain) and I really can't tell any difference in the color of my teeth before and after using them. I used them as intended and increased the time they stayed on my teeth to see if that would make a difference. None of these options worked. I don't know if the increased adhesive somehow neutralized the bleach chemicals, but they don't really work for me. Needless to say, I won't be buying them again. I wish I could get my money back but I threw away the receipt as I used the previous version for a couple of years and was very happy so I didn't expect circumstances to force me to return it.
