I saw a recent photo of myself (where admittedly the lighting was horrible) and I was not happy with the non-bright-white state of my teeth. I don't drink a lot of red wine, and coffee is my only real tooth-staining vice, but I still felt like my teeth could be so much whiter. So I hopped to my local Target and was happy to find Crest 3D Whitestrips Shimmer White. Applied daily it promises a much whiter smile in 12 days (you also could double up daily and accomplish this in six days). After just the first application ,I could tell my teeth where already whiter. And after six days of one application daily I was happy with the results of my whitening (and now I have six strips left over for when I feel like they could use a freshening up). Crest's Whitestrips have come a long way from when I first used them many years ago -- they stuck perfectly to my teeth and the chemical didn't seep everywhere and ruin my taste buds. I also, happily, didn't notice as much tooth sensitivity as I had before. All in all, it was the best $35 I had spent in a while!
You can get Crest 3D Whitestrips Shimmer White for $35 exclusively at Target stores and target.com.
