Review on 🦷 Crest 3D Whitestrips Charcoal Mint, Teeth Whitening Kit, 28 Strips (14 Treatments) + 1 Tube of Flavor Serum by Jim Bodnarchek

In terms of whitening properties, it's really great. I notice and love the difference in whitening my teeth! The taste is pleasant and it is very easy to use and very comfortable to wear. My only one is tiny and I repeat that's just a tiny criticism, sometimes after wearing these and even after rinsing and brushing I see a tiny wavy white line down the center of one of my front teeth which makes me uneasy. This reminds me of the reason I stopped using Crest Whitening Strips years ago. My actor friend also uses Crest Whitening Strips and I also noticed this white wavy line on his tooth. It's actually noticeable. I also read a review of these crest whitening strips or other crest whitening strips where someone noticed the same thing on their tooth. I want Cross to understand this and try to solve this problem and find a way to fix it. No other whitening system I've tried does this. That's my only small concern. But then again, in terms of whitening abilities, convenience, taste, and ease of use, it's great!
