Crest whitening strips
« on: July 05, 2018, 02:39:49 AM »
Hi all,
So I used crest whitening strips for the first time ever today. I left them on for an hour. When I took them off I noticed all of my teeth are transparent on the bottom and they are also sensitive. I learned that transparency happens from over whitening teeth however the last time I did was 2 years ago for a laser treatment.

Did anyone else have the problem of transparency after use? I’m extremely worried as I read online that it is permanent.
