I love seeing the difference in my teeth after using the strips, even after the first few applications. I do a box every six months. It does the job I need. Only thing I don't like is the feeling left on your teeth after the application. However, this will not stop me from buying it again.

These products completely are changing my life I am in recovery now almost 3 years sober but have always struggled with appearance issues and my teeth weren't so white after carelessness and ciggerettes smoking. My teeth are getting whiter I'm loosing weight and starting to love myself again and because of this product I love my smile again.

I was a little dubious at first but after a couple of uses the results were remarkable. I`ve just stopped smoking but my teeth were never that bad as I frequently go to the dentist. After 10 days my teeth are now a dazzling brilliant white and pleased with the comments I`ve received. No sensitivity at all. Easy to apply and remove when finished. Highly recommended and cheaper than other methods.

I love red wine, coffee, and iced tea. The worst possible trifecta for also wanting white teeth! However, crest white strips have saved my booty on more than one occasion. Following the directions exactly from the box has made a HUGE difference in the color and brightness of my smile. A huge huge confidence boost to have whiter teeth! Best money I have ever spent.

Crest 3-d white strips were recommended to me by my dental hygienist when I asked about professional teeth whitening. She said that they work just as well for a fraction of the price. She was right. After a seven day treatment my teeth were noticeably whitened and people started commenting on how white they were. I use the treatment every couple months to keep my teeth looking white. Easy to use!

I LOVE these! I have used these white strips for years. The initial box made my teeth noticeably brighter. Now I keep a box on hand and just use them here and there when I need a quick refresher. The extra treatments may not be necessary for some, but I'm an avid coffee drinker and these gems make quick work of the coffee stains.

Not terrible at whitening, it does a bit but this are very, very intense and strong. I would not recommend for those with sensitive tether or gums as it made mine hurt for days. Definitely a more “affordable” item for whitening your teeth but I prefer to use something a little more gentle.

My favorite teeth whitening product. I have only ever used these because they have yet to fail me. I have never had a problem and my smile is always glistening. A great price for a white smile without the hassle of getting your teeth whitened professionally.

I started using Crest Professional White Strips last year. I whiten my teeth once a year. These white strips are by far the best product on the market. My teeth are not really stained, however, due to me being an avid coffee drinker, I choose to whiten yearly. These strips are awesome, and I have not had any sensitivity so far. Try them out, and I'm sure you won't be disappointed.

These 100% exceeded my expectations. My teeth were so stained and I used these for 2 months. They were so effective and easy to use. The only con was that my teeth were more sensitive for awhile. But in my opinion it was worth it. I would definitely recommend and but again.
