I have been using for 2 weeks and haven't noticed any change. A couple packs of my strips wouldn't even stick to my teeth. Very disappointing. I'm guessing I received an old product.

[This review was collected as part of a promotion.] I'm so excited about this journey..I've been wanting to try these for awhile but have been a bit pricey so when I saw these I jumped on the opportunity

I am on day 4 of using the white strips as indicated in the directions, and I've noticed my teeth have gotten whiter. Although, I would like some clarification as to if you're to brush before, or after strip application??

I have been using these white strips for the past couple of years and they have actually changed my teeth! I can tell a huge difference in my smile when I dont use them for a while. All of my friends use them now too!!! Love them so much.

This product really works! I just followed the directions on the package and used the strips. Teeth look whiter. I use the strips about once a week just to keep my teeth white.

I am using CREST its very unambiguous product.I love it.its reduced yellowish color quickly not an week its done in few days.Thank you CREST Team members......TEETH+CREST=WHITENING TEETH+OTHERS(COSTLY)=YELLOw

Whenever I use one of these strips, it makes me feel dazzling. They brighten up my smile enough to make a difference. I get compliments all the time on how white my teeth are. I cannot live without them. I keep one in my make-up case in my purse.

I had put off my dental work and had family issues come up that made me totally forget to bleach to prepare for it. I bought these 5 days before and used them and can't believe how well they worked! And no sensitivity at all!

I bought this product at a local Festival store about 2 months ago. When attemnpted to use the strips the backing would not come off the as I pulled the actual treated strip. The backing and strip were then impossible to seperate.

Strips are easy to apply. Seems to take several weeks to notice any improvement. Stubborn stains on cracked teeth are still visible but fading. The strips cause gum irritation and inflammation.
