Review on 🦷 Crest 3D Whitestrips Classic White Teeth Whitening Kit: 10 Treatments - 20 Strips by Lori Okuno

Their enamel is completely transparent. The natural color of the teeth is determined by the color of the dentine. My dentin is quite yellow and after this product removed all superficial stains from my teeth the lightest I got was maybe a light pale eggshell color. The only way to achieve whiter teeth with yellow dentin is through abrasion, which changes the opacity of the enamel, or through porcelain veneers. However, if your dentin is less pigmented, you should at least get some shade of white. I noticed a difference after just 2 treatments. They peaked for me after the 6th treatment. They also resemble the smell of washing powder.
