I have noticed a slight improvement already with using these whitening strips. The only downside is that I have noticed is one tooth on my bottom row of teeth is very sensitive during and after the application. At first I was a bit worried but crest on the package says that it may very well happen and that it is normal. That was a relief. I will be posting some pictures soon of my teeth on my facebook and twitter. My facebook name is leah stobe my icon is of minnie mouse, my twitter is @chrissy11217 So far, so good. Excited to see how white my teeth do get.
I was invited, via influenster and crest, to review the whitening strips. I have just used it for the first time. I have noticed some significant changes.
1. The box is much nicer than it once was, I like the structure and the sturdiness, especially since I have to keep this box for many days and it typically sits next to a sink.
2. The gel formula on the strips have changed. The previous white strips I used, and was dissatisfied with had a watery gel that slipped on my teeth. This new gel formula is definitely improved and a thicker and sturdier.
