Crest Whitestrips actually do make your teeth whiter. I could see the difference after about 3 or 4 days of applications. It can be somewhat irritating to your gums if you position them too much over them, so try to do it in a way that they fold more over the back of your teeth rather than on the gums. If they are too irritating, I suggest you use once a day instead of the directed twice.

It does make my teeth so much whiter but i found that while i was using them, my teeth got very sensitive. I was using them constantly every day then i stopped for a few day. When i started using them again, my teeth was feeling so painful, I couldn't sleep. The feeling lasted for 24 hrs then disappeared gradually. Great result but quite painful for me.

Delivery took a while however would recommend product. Wanted a brighter smile before my wedding. Used all the strips consecutively, I would say that I could tell a difference with the whitening of my teeth from day 7 and it got whiter after that too. Downside is I was left with very sensitive teeth with took weeks to go. Otherwise very good product, will recommend and may use again in the future for touch ups for a short duration for a week.

I have used white strips ever since they came out. I have occasionally tried other brands and have always been disappointed. You really do get what you pay for. I have had a ton of trouble getting other brands to adhere to my bottom teeth. These adhere great and cover more teeth because they stretch. Love them.

This is my first time doing any type of whitening treatment and I love the results! It does make my teeth sensitive but it did go away pretty fast.

Was skeptical at first about how good these would be but I’m very very satisfied and will continue to buy these through eBay. So much cheaper than from the store.

I am very satisfied with this purchase. The product was delivered in a timely manner and everything was just as described. I have to admit, I was worried about the possibility of the product causing sensitivity so I was extremly cautious with this product. After the second application of this product, my teeth did feel mildly sensitive so I stopped use of this product for about 2-3 days. After I gave my teeth that much needed break, I continued using the product and my teeth felt fine. After using this product my teeth are definatley whiter and I 100% recomend this product. However, A word of advice the I would give is to avoid placing this product on your gums at all costs as it will whiten them and I will cause a burning sensation.

I love these strips. The first time I tried them I followed the instructions explicitly and my teeth looked absolutely beautiful when I was done. All the yellowing and stains from drinking cola and coffee were gone. I now use them as needed to keep my teeth their whitest. Totally recommend!

The stripes arrived in about two weeks just like promised. They were pretty easy to use and I definitely saw results after using them 10 days in a row! They didn't make my teeth hurt although drinking hot or cold drinks felt a bit unpleasant. Only downside is that I feel like the whitening isn't very long-lasting... I quit drinking coffee while using the stripes but as soon as I started to drink it again I felt like my teeth got as yellow as before after only a week. However I will definitely buy these again to maintain the whiteness!
