Bests & Worsts Reviews from Amazon

These strips are super gross. Gross in that they tend to turn to a jelly while wearing them. At least they taste good. And if you’re buying them for whitening - these strips are for you!! I find it helpful to place the strip, then use my fingernails to gently shove the strip between my teeth, as they really do whiten, and I want the cracks to whiten as well. I noticed a difference after the first try. After three I started getting comments on my teeth. By day three on a Crest strip, I would be on my knees begging for sensitive tooth relief - no issue with these strips so far.
